These three requirements pull in opposing directions: reducing backlash by tightening the tooth clearance increases mesh friction and heating that accelerates wear; increasing the tooth face width to improve fatigue life increases the gear inertia; specifying the smallest possible gear to minimise inertia reduces the tooth bending strength margin. The robot gear designer must find the optimal balance of these parameters for each joint&#8217;s specific torque, speed, and duty cycle.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1545 aligncenter\" src=\"https:\/\/gearrack.top\/wp-content\/uploads\/2026\/07\/Tractor-Spur-Gears.webp\" alt=\"Tractor Spur Gears\" width=\"600\" height=\"600\" srcset=\"https:\/\/gearrack.top\/wp-content\/uploads\/2026\/07\/Tractor-Spur-Gears.webp 600w, https:\/\/gearrack.top\/wp-content\/uploads\/2026\/07\/Tractor-Spur-Gears-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 600px, 100vw\" \/><\/p>\n<p style=\"font-size: 15.5px; margin: 0 0 20px;\">Korea Ever-Power&#8217;s <a style=\"color: #2563a8; font-weight: bold; text-decoration: none; border-bottom: 2px solid #f97316;\" href=\"https:\/\/gearrack.top\/ja\/product-category\/spur-gear\/\">spur gears for robotics applications<\/a> are manufactured in 20CrMnTi case carburized and profile ground (the standard specification for industrial and collaborative robot joint gears where the combination of high contact fatigue resistance and low surface roughness after grinding is required), 17-4 PH stainless steel precipitation hardened (for medical and surgical robot applications where sterilisability and corrosion resistance are required alongside the mechanical performance), and PEEK high-performance polymer (for collaborative robot and cobot applications in food, pharmaceutical, or cleanroom environments where metal contamination is unacceptable and the joint torque is below the PEEK material&#8217;s load-carrying capacity). All robotic spur gears are individually measured for transmission error below 4 \u03bcrad at the module-appropriate pitch circle before shipment \u2014 this measurement directly correlates to the robot&#8217;s positioning repeatability as a component of the total drivetrain transmission error budget.<\/p>\n<p style=\"font-size: 15.5px; margin: 0 0 24px;\">Backlash control in robotic spur gears requires both tight manufacturing tolerances and an appropriate installation strategy. The backlash at a spur gear mesh is determined by the combination of the centre distance variation (how far the pinion centre deviates from the theoretical pitch-point-contact distance with the wheel) and the tooth thickness deviation of both gears. For a M1.5 robot joint spur gear pair, the theoretical backlash at zero centre distance error and nominal tooth thickness is approximately 0.04\u20130.06 mm \u2014 equivalent to 1.5\u20132.3 arc-minutes at a 30-tooth pinion. Achieving the 1 arc-minute or below target requires either: (1) <strong>Tight tolerance tooth thickness<\/strong> \u2014 manufacturing both gears to the upper end of the tooth thickness tolerance (thicker teeth, less clearance) and selecting matched pairs from the production lot whose combined tooth thickness minimises backlash; or (2) <strong>Adjustable centre distance<\/strong> \u2014 designing the robot joint housing with an eccentric adjustment on the motor mounting that allows the centre distance to be reduced until the backlash reaches the target, then locking the motor position. Korea Ever-Power supplies matched robotic spur gear pairs with the measured tooth thickness of each gear and the calculated assembly backlash range documented on the measurement certificate, enabling the robot builder to select the assembly centre distance that achieves the target backlash without scrapping gears.<\/p>\n<figure style=\"margin: 0 0 28px;\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; border: 1px solid #d1d9e6;\" title=\"Precision Spur Gears for Robotics \u2014 Korea Ever-Power\" src=\"https:\/\/gearrack.top\/wp-content\/uploads\/2026\/07\/Spur-Gears-European-Standard.webp\" alt=\"precision spur gears robotics European standard DIN Korea Ever-Power\" \/><figcaption style=\"font-size: 12.5px; color: #64748b; margin-top: 10px; padding: 8px 14px; border-left: 4px solid #f97316; background: #fff; line-height: 1.65;\">Korea Ever-Power precision spur gears for robotic joint drives \u2014 European standard (DIN\/ISO) tooth profile, M1.5, 28T and 42T pair shown for collaborative robot shoulder joint application. 20CrMnTi case carburized HRC 60\u201362, profile ground DIN 5, individual transmission error measurement \u22643.5 \u03bcrad.

These wrist gears are driven by high-speed servo motors (3,000\u20136,000 RPM at the motor shaft) through a reduction ratio of 50:1\u2013150:1 achieved across multiple stages including a spur gear pre-stage and a harmonic drive final stage. The spur gear pre-stage in the robot wrist runs at the highest pitch line velocity in the joint (often 5\u201312 m\/s at M1.5\u2013M2 module), making it the most noise-sensitive gear in the system and requiring DIN 5\u20136 ground profile with tip relief to meet the robot manufacturer&#8217;s specification for transmitted vibration to the tool flange.

Collaborative robots (Universal Robots UR series, FANUC CRX, KUKA LBR iiwa, Doosan, Techman) share the workspace with human operators and require the joint drive to be transparent to external forces \u2014 the robot must be able to detect the force a human applies to its arm and stop or comply with it before a harmful impact occurs. This safety requirement places unique demands on the spur gear: the gear backlash must be minimised (to prevent the robot controller from misinterpreting backlash dead-band reversal as external force), and the gear friction must be low and consistent (so the joint torque sensor signal is not dominated by gear friction hysteresis). Korea Ever-Power cobot spur gears are individually measured for torque hysteresis (the difference in output torque when the same input torque is applied in CW vs CCW direction), with a maximum specification of 3% of rated torque at the gear mesh \u2014 a key parameter not measured for standard industrial gears but essential for collaborative robot safety compliance.<\/p>\n<\/div>\n<\/div>\n<div style=\"display: flex; flex-wrap: wrap; background: #fff; border-bottom: 2px solid #f4f6f9; overflow: hidden;\">\n<div style=\"background: #f97316; padding: 20px 22px; min-width: 130px; display: flex; flex-direction: column; justify-content: center;\">\n<p style=\"font-size: 9px; font-weight: 800; letter-spacing: 2px; text-transform: uppercase; color: rgba(0,0,0,0.4); margin: 0 0 5px;\">ROBOT 03<\/p>\n<p style=\"font-size: 13px; font-weight: 800; color: #fff; margin: 0; line-height: 1.3;\">SCARA ROBOT<br \/>\nARM<\/p>\n<\/div>\n<div style=\"padding: 18px 22px; flex: 1; min-width: 220px;\">\n<p style=\"font-size: 14.5px; color: #374151; line-height: 1.78; margin: 0;\"><strong style=\"color: #1c2330;\">Spur gear specification:<\/strong> M0.8\u2013M2, 20CrMnTi carburized, DIN 5\u20136, flat (minimal face width for compactness in the planar SCARA arm structure), high tooth count for smoother transmission.

Korea Ever-Power SCARA robot spur gears use a high tooth count (\u226520T) to increase the contact ratio above 1.7, which smooths the transmission error at the high cycle rates of SCARA pick-and-place operations.

Gears with TE above the specification limit are rejected \u2014 not regraded to a lower quality class, since robotic spur gears in the production batch are specified for a specific robot model and cannot be substituted to a lower-specification application.<\/figcaption><\/figure>\n<\/section>\n<section style=\"margin: 64px 0 0;\">\n<h2 style=\"font-size: clamp(18px,2.6vw,24px); font-weight: 800; color: #1c2330; margin: 0 0 20px; padding-bottom: 10px; border-bottom: 3px solid #2563a8;\">Backlash Elimination Methods for Robotic Spur Gears<\/h2>\n<p style=\"font-size: 15.5px; margin: 0 0 20px;\">For robot applications that require backlash levels below 0.5 arc-minutes \u2014 typically high-precision assembly robots, measurement systems, and surgical robots \u2014 standard spur gears with tightly controlled tooth thickness can no longer achieve the target, and anti-backlash gear mechanisms are required. Korea Ever-Power manufactures several anti-backlash spur gear configurations for robotic applications where the standard tight-tolerance gear pair is insufficient.<\/p>\n<div style=\"display: flex; flex-wrap: wrap; gap: 16px; margin: 0 0 28px;\">\n<div style=\"flex: 1 1 210px; background: #fff; border: 1px solid #d1d9e6; border-top: 4px solid #2563a8; border-radius: 4px; padding: 20px 22px;\">\n<h3 style=\"font-size: 13.5px; font-weight: 800; color: #1c2330; margin: 0 0 10px;\">Spring-Loaded Split Gear<\/h3>\n<p style=\"font-size: 13.5px; color: #4b5768; line-height: 1.72; margin: 0;\">Two spur gear halves with the same tooth count mounted co-axially on the same shaft, with a torsion spring between them that pre-loads the tooth flanks of each half in opposite rotational directions against the mating gear&#8217;s teeth. The spring pre-load fills the backlash gap and maintains tooth flank contact in both rotation directions. Limitation: the spring pre-load adds a constant drag torque at the mesh, reducing efficiency and heating the oil \u2014 the spring rate must be sized below the minimum drive torque to avoid dynamic gear separation at high speed. Best for: SCARA robots at moderate cycle rates, measurement robot axes with low dynamic forces.<\/p>\n<\/div>\n<div style=\"flex: 1 1 210px; background: #fff; border: 1px solid #d1d9e6; border-top: 4px solid #f97316; border-radius: 4px; padding: 20px 22px;\">\n<h3 style=\"font-size: 13.5px; font-weight: 800; color: #1c2330; margin: 0 0 10px;\">Adjustable Centre Distance Mount<\/h3>\n<p style=\"font-size: 13.5px; color: #4b5768; line-height: 1.72; margin: 0;\">The motor or intermediate gear shaft is mounted on an eccentric bushing or a sliding rail that allows the centre distance between the pinion and wheel to be reduced below the standard pitch-point distance. Reducing the centre distance from the nominal value tightens the mesh and reduces backlash \u2014 at the cost of increased tooth load from the interference pre-loading. This is the most common anti-backlash approach in industrial robot wrist joints because it requires no additional parts (the eccentric is in the housing) and the backlash can be re-adjusted after the tooth surface runs in and wears to a stable level. Korea Ever-Power supplies eccentric bushing mounting hardware for robotic spur gear housings on request.<\/p>\n<\/div>\n<div style=\"flex: 1 1 210px; background: #fff; border: 1px solid #d1d9e6; border-top: 4px solid #1c2330; border-radius: 4px; padding: 20px 22px;\">\n<h3 style=\"font-size: 13.5px; font-weight: 800; color: #1c2330; margin: 0 0 10px;\">Zero-Backlash Crowned Tooth<\/h3>\n<p style=\"font-size: 13.5px; color: #4b5768; line-height: 1.72; margin: 0;\">A micro-crowning of the tooth profile (a slight convex curvature in the face width direction) allows the gear mesh to be assembled with slight misalignment or centre distance reduction without edge loading \u2014 making it compatible with tighter centre distance settings for backlash reduction. The crowned tooth form is generated during the profile grinding process using a modified grinding wheel path programmed into the CNC gear grinder. Crowning amount: 2\u20135 \u03bcm face convexity for M1\u2013M2 robot gears. This enables aggressive centre distance reduction (reducing the nominal backlash by 40\u201360%) without the risk of tooth edge contact that would occur with a standard involute tooth at the same centre distance reduction. Korea Ever-Power applies crowned tooth profiles on all robotic spur gears at M1.5 and above where backlash below 1 arc-minute is specified.<\/p>\n<\/div>\n<\/div>\n<figure style=\"margin: 0 0 24px;\"><img decoding=\"async\" style=\"width: 100%; height: auto; display: block; border-radius: 6px; border: 1px solid #d1d9e6;\" title=\"Korea Ever-Power Robot Spur Gear Manufacturing\" src=\"https:\/\/gearrack.top\/wp-content\/uploads\/2026\/07\/Ever-Power-workshop-1.webp\" alt=\"Korea Ever-Power precision gear manufacturing robot joint spur gear\" \/><figcaption style=\"font-size: 12.5px; color: #64748b; margin-top: 10px; padding: 8px 14px; border-left: 4px solid #f97316; background: #fff; line-height: 1.65;\">Korea Ever-Power precision spur gear manufacturing facility for robotic joint applications \u2014 CNC profile grinding machines with 0.1 \u03bcm positioning resolution for M0.5\u2013M3 small-module robot gears. Small-module robotic spur gears (M0.5\u2013M1) present significant manufacturing challenges: the tooth height is only 1.125\u20132.25 mm, the tooth root radius must be ground without undercutting the adjacent tooth flank, and the profile measurement requires a stylus tip radius of 0.1 mm or smaller to trace the full involute from root to tip without measurement error from stylus interference. Korea Ever-Power uses laser profilometry as a supplementary measurement technique for M0.5\u2013M0.8 gears where conventional involute measurement stylii cannot reach the root area \u2014 laser profilometry provides non-contact measurement of the complete tooth profile including the root radius, confirming that profile ground roots meet the DIN 4\u20135 tolerance at all measurement positions from root to tip.<\/figcaption><\/figure>\n<\/section>\n<section style=\"margin: 64px 0 0;\">\n<h2 style=\"font-size: clamp(18px,2.6vw,24px); font-weight: 800; color: #1c2330; margin: 0 0 24px; padding-bottom: 10px; border-bottom: 3px solid #2563a8;\">Frequently Asked Questions \u2014 Spur Gears for Robotics<\/h2>\n<div style=\"display: flex; flex-direction: column; gap: 12px;\">\n<div style=\"background: #fff; border: 1px solid #d1d9e6; border-radius: 4px; overflow: hidden;\">\n<div style=\"padding: 16px 20px; display: flex; align-items: flex-start; gap: 14px; background: #f7f9fc; border-bottom: 1px solid #e8edf4;\"><span style=\"background: #1c2330; color: #f97316; font-size: 10px; font-weight: 800; padding: 3px 10px; border-radius: 2px; white-space: nowrap; letter-spacing: 1px;\">Q 01<\/span><\/p>\n<p style=\"font-size: 14.5px; font-weight: bold; color: #1c2330; line-height: 1.35; margin: 0;\">Our SCARA robot&#8217;s J2 joint is showing increasing position error after 18 months of operation \u2014 the ISO 9283 repeatability has degraded from \u00b10.02 mm to \u00b10.08 mm. The joint spur gears are worn. What specification should we use for the replacement gears to improve on the original?<\/p>\n<\/div>\n<div style=\"padding: 18px 20px;\">\n<p style=\"font-size: 14.5px; color: #374151; line-height: 1.78; margin: 0;\">The repeatability degradation from \u00b10.02 mm to \u00b10.08 mm over 18 months in a SCARA J2 joint indicates that the combined gear wear and backlash increase have exceeded the controller&#8217;s ability to compensate \u2014 the dead-band in the position control loop is now \u00b10.08 mm rather than the designed \u00b10.02 mm. To achieve the original specification with replacement gears and also improve on the original: (1) <strong>Upgrade the material from C45 (if original) to 20CrMnTi carburized:<\/strong> if the original gears were hobbed C45 (often used in cost-optimised SCARA robots), the carburized replacement will have 3\u20134\u00d7 higher contact fatigue resistance and will sustain the original backlash for significantly longer than 18 months. (2) <strong>Upgrade the quality class from DIN 7 to DIN 6:<\/strong> the tighter profile tolerance of DIN 6 reduces the transmission error contribution to the position error budget, allowing the robot controller to achieve better repeatability even with the same total backlash. (3) <strong>Apply crowned tooth profile on the replacement gears:<\/strong> the micro-crowning allows a tighter centre distance setting that reduces the initial backlash from the original design value, giving more wear margin before repeatability degrades to the \u00b10.08 mm limit again. (4) <strong>Record the J2 assembly backlash after replacement:<\/strong> use a dial indicator tangentially against the output gear teeth with the input locked, and record the dead-band in the indicator reading \u2014 this establishes the baseline for future maintenance monitoring. Korea Ever-Power can provide matched replacement pairs with individual backlash documentation for the most common SCARA robot J2 gear sizes \u2014 submit the SCARA robot model and the worn gear&#8217;s tooth count, OD, and bore for cross-reference and quotation.<\/p>\n<\/div>\n<\/div>\n<div style=\"background: #fff; border: 1px solid #d1d9e6; border-radius: 4px; overflow: hidden;\">\n<div style=\"padding: 16px 20px; display: flex; align-items: flex-start; gap: 14px; background: #f7f9fc; border-bottom: 1px solid #e8edf4;\"><span style=\"background: #1c2330; color: #f97316; font-size: 10px; font-weight: 800; padding: 3px 10px; border-radius: 2px; white-space: nowrap; letter-spacing: 1px;\">Q 02<\/span><\/p>\n<p style=\"font-size: 14.5px; font-weight: bold; color: #1c2330; line-height: 1.35; margin: 0;\">What is the minimum order quantity and lead time for custom robotic spur gears at M1 and M1.5 module with DIN 5 quality class?<\/p>\n<\/div>\n<div style=\"padding: 18px 20px;\">\n<p style=\"font-size: 14.5px; color: #374151; line-height: 1.78; margin: 0;\">Korea Ever-Power robotic spur gear supply parameters for M1\u2013M1.5, DIN 5: <strong>Standard catalogue sizes (M1, M1.5 with tooth counts 12T, 16T, 20T, 24T, 28T, 32T, 36T, 40T in 20CrMnTi carburized):<\/strong> available from stock or in 5\u201310 working days; minimum order 5 pieces per size.

This is sufficient for the J5 and J6 wrist joints of small collaborative robots (e.g. Universal Robots UR3, FANUC CRX-5iA) where the rated wrist torque is 10\u201328 Nm. For J1\u2013J3 shoulder and elbow joints with rated torques of 50\u2013100 Nm, PEEK is undersized at M1.5 and would require M3\u2013M4 module to carry the load \u2014 at which point the gear is large enough to negate the mass advantage of using PEEK over steel. Practical PEEK robot spur gear applications: (1) Food and pharmaceutical cobot wrists (UR3\/UR5 food-grade variants) where the FDA 21 CFR 177.2415 compliant PEEK material prevents metallic contamination in case of gear chip generation. (2) Cleanroom assembly robots where the grease-free operation of PEEK (running dry without lubricant for the first 1 million cycles) and zero oil mist generation are required for ISO Class 4 cleanroom compatibility. (3) MRI-compatible surgical robots where ferromagnetic metal gears are excluded. For all PEEK robot gear applications, Korea Ever-Power recommends a duty cycle calculation confirming the operating temperature remains below 220\u00b0C (PEEK\u2019s continuous service limit) and the contact stress remains below 40 MPa (the PEEK fatigue endurance contact stress at 10\u2077 cycles).<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<section style=\"margin: 72px 0 0;\">\n<div style=\"text-align: center;
