Product Overview<\/h2>\n
\n
\n \"Plastic\n <\/div>\n
\n

Plastic bevel gears<\/strong> have a conical shape with straight or spiral-cut teeth and transmit motion between two axles that intersect, changing the rotation axis direction. They are the standard gear type for 90\u00b0 direction changes in compact drives \u2014 power tools, automotive applications, food production machines, consumer electronics, chemical equipment, toys, and medical equipment. Korea Ever-Power’s plastic bevel gears are available in Plastic, POM, and Nylon (and other materials as required), module M0.25 and up, with ratios 1:1, 2:1, 3:1, 4:1, 5:1, operating temperature \u221240\u00b0C to +80\u00b0C. Standard catalogue dimensions from M0.5 (GB05M016) through M1 and above, in both 1:1 and other ratios.<\/p>\n

Korea Ever-Power’s plastic bevel gears<\/a> offer: lightweight and non-rusting construction; quiet operation (especially the spiral-cut variant which is smoother and less noisy than straight bevel); injection-moulding enabling low cost and large production volumes; ability to operate without lubrication by mating with metal gears; and a wide choice of standard sizes from the Korea Ever-Power catalogue. The degree of dimensional change with temperature, moisture absorption, and chemical exposure depends on material grade \u2014 Korea Ever-Power advises on the correct material for each application.<\/p>\n<\/p><\/div>\n<\/div>\n

Plastic Bevel Gear Operating Principles<\/h2>\n

\"All<\/p>\n

Bevel gears transmit power between intersecting shafts \u2014 the most common arrangement is 90\u00b0 (right-angle output). Understanding bevel gear geometry and the straight vs spiral tooth choice is essential for correct selection:<\/p>\n

\n
\n

Conical Pitch Surface<\/h3>\n

Bevel gear pitch surfaces are cones \u2014 the apex of both mating bevel gears’ pitch cones coincides at the intersection point of the two shaft axes. The teeth are cut on the conical surface, decreasing in size from the large (heel) end to the small (toe) end. The tooth form varies along the face width to maintain the correct involute profile at the mean pitch diameter, where tooth load analysis is typically performed. This tapering tooth form distinguishes bevel gears from cylindrical gears and makes them the only standard gear type for intersecting-shaft power transmission.<\/p>\n<\/p><\/div>\n

\n

Straight vs Spiral Bevel Teeth<\/h3>\n

Straight bevel gears have teeth cut radially on the cone surface \u2014 the teeth are parallel to the pitch cone generatrix. They engage abruptly across the full tooth width, producing an impulse at each tooth mesh (similar to spur gears). Spiral bevel gears have curved, oblique teeth \u2014 contact begins at one end and progresses gradually, like helical gears. The spiral bevel version is smoother and less noisy than straight bevel on all designs \u2014 at the cost of higher manufacturing complexity and the presence of an axial thrust force in both bevel shafts that must be reacted by thrust bearings. Korea Ever-Power’s plastic bevel gears are available in both tooth forms.<\/p>\n<\/p><\/div>\n

\n

Gear Ratio and Shaft Angle<\/h3>\n

Bevel gear ratio i = Z\u2082\/Z\u2081 = tan(\u03b4\u2081)\/tan(\u03b4\u2082) \u2014 where \u03b4\u2081 and \u03b4\u2082 are the pitch cone angles of the pinion and gear respectively. For 90\u00b0 shaft angle bevel gears, the two pitch cone angles sum to 90\u00b0 (\u03b4\u2081 + \u03b4\u2082 = 90\u00b0). For a 1:1 ratio, both gears have \u03b4 = 45\u00b0 and are geometrically identical (miter gears). For higher ratios (2:1, 3:1), the pinion has a smaller cone angle and the gear has a larger cone angle. Korea Ever-Power’s standard catalogue covers 1:1 through 5:1 at modules M0.5 and M1; custom ratios available.<\/p>\n<\/p><\/div>\n

\n

Operating Without Lubrication<\/h3>\n

Plastic bevel gears can operate without lubrication \u2014 especially when the plastic bevel gear meshes with a metal gear (typically the harder material is metal, and the plastic gear acts as the softer, sacrificial wear element). The POM bevel gear’s inherently low friction coefficient (\u03bc \u2248 0.1 against steel) provides adequate lubrication through the POM surface’s tribological properties without requiring added oil or grease. This dry-running capability is essential in food industry, medical, and clean-room applications where lubricant contamination is unacceptable.<\/p>\n<\/p><\/div>\n

\n

Plastic Bevel Gear Cautions<\/h3>\n

Plastic bevel gears require design caution for three characteristics: (1) Low strength \u2014 plastic bevel gears have lower tooth root bending strength than metal, limiting the maximum torque; tooth width should be slightly narrower than the equivalent metal gear to reduce the risk of mechanical interference at the toe end. (2) Heat retention \u2014 plastic has low thermal conductivity; sustained high-speed, high-load operation causes thermal build-up that degrades the tooth surface; duty cycles must be limited at elevated ambient temperatures. (3) Dimensional change \u2014 thermal expansion and moisture absorption both change dimensions beyond metal equivalent; backlash must be set at the equilibrium operating condition, not the as-moulded dry-room condition.<\/p>\n<\/p><\/div>\n

\n

Injection Moulding Plastic Bevel Gears<\/h3>\n

Plastic straight bevel gears are injection-moulded with straight-pull (or simple core-pull) moulds \u2014 the tapered conical tooth form allows axial ejection from the mould without an unscrewing mechanism (unlike helical gears). This simplifies the mould design and reduces tooling cost. Spiral bevel gears require more complex moulds with curved cavity surfaces, increasing mould cost. For most plastic bevel gear applications where the load is light and noise is moderate, straight bevel gears from injection moulds are preferred for their lower mould cost and faster production cycle.<\/p>\n<\/p><\/div>\n<\/div>\n

Positive Characteristics of Plastic Bevel Gears<\/h2>\n

\"Ever-Power<\/p>\n

\n
\n

Lightweight<\/h3>\n

POM and nylon bevel gears are 5\u20137\u00d7 lighter than equivalent steel bevel gears. In hand-held power tools, this weight reduction reduces user fatigue. In battery-powered devices, the lower rotor inertia of the lightweight bevel gear reduces the motor’s acceleration energy demand, directly extending battery life per charge cycle.<\/p>\n<\/div>\n

\n

Non-Rusting<\/h3>\n

POM and nylon bevel gears do not rust \u2014 they are completely corrosion-resistant to the salt spray, humidity, and cleaning chemicals that destroy unprotected steel bevel gears. This non-rusting property is critical in food machinery, marine equipment, garden tools, and outdoor consumer products where steel bevel gears would require expensive stainless steel or surface treatment to maintain corrosion resistance.<\/p>\n<\/div>\n

\n

Quiet Operation<\/h3>\n

Plastic bevel gears are significantly quieter than metal bevel gears \u2014 from the inherent damping of POM and nylon materials. In consumer electronics and household appliances where gear noise is a product quality signal to the user, the quieter plastic bevel gear improves the perceived product quality without the cost of adding acoustic enclosures. The spiral bevel variant is quieter still \u2014 typically 3\u20136 dB(A) quieter than the equivalent straight bevel at the same speed.<\/p>\n<\/div>\n

\n

Low Cost at Volume<\/h3>\n

Injection moulding enables low-cost, large-volume production of plastic bevel gears \u2014 once the mould is made, each part is produced in seconds at minimal incremental cost. The standard M0.5 and M1 bevel gears in Korea Ever-Power’s catalogue use existing mould tooling \u2014 no new tooling cost for standard sizes. This makes plastic bevel gears accessible for high-volume, cost-sensitive consumer applications.<\/p>\n<\/div>\n

\n

Operates Without Lubrication<\/h3>\n

POM bevel gears can operate without lubrication when mating with metal pinions \u2014 the POM’s intrinsic tribological properties provide adequate tooth surface lubrication in light-duty applications. This eliminates maintenance (no re-greasing) and contamination risk, making plastic bevel gears the preferred choice for food machinery, medical equipment, and sealed consumer product applications.<\/p>\n<\/div>\n<\/div>\n

Consumer Electronics<\/h3>\n

Fine-pitch POM bevel gears (M0.25\u2013M0.5) in camera lens focus and tilt drives, phone camera module tilt actuators, and small appliance 90\u00b0 drive mechanisms. The standard M0.5 catalogue gear (GB05M016, 16T, OD 8.7 mm, bore 3.0 mm) covers most miniature consumer electronics bevel gear applications \u2014 available from Korea Ever-Power’s stock without custom tooling.<\/p>\n<\/div>\n

\n
<\/div>\n

Toys and Robots<\/h3>\n

ABS and nylon bevel gears in RC cars (front axle differentials), walking robot leg joints, and educational robot kits. The 1:1 ratio bevel gear pair is standard in toy differential mechanisms; the lightweight, low-cost, and self-lubricating properties match toy product design requirements exactly. The plastic bevel gear meets toy safety standards (no sharp edges, no toxic materials) inherently.<\/p>\n<\/div>\n

\n
<\/div>\n

Medical Equipment<\/h3>\n

POM and PEEK bevel gears in medical instrument drives, surgical robot joints, and diagnostic equipment positioning stages. The dry-running, no-lubrication operation eliminates contamination risk in sterile medical environments; PEEK bevel gears can be steam-autoclaved at 134\u00b0C for repeated sterilisation cycles; the lightweight construction reduces the arm weight of surgical robots where surgeons hold the instrument continuously.<\/p>\n<\/div>\n<\/div>\n

Frequently Asked Questions<\/h2>\n
\n
\n

Should I choose straight or spiral bevel gears in plastic?<\/p>\n

Straight bevel gears are the standard choice for most plastic bevel gear applications \u2014 simpler mould, lower tooling cost, adequate noise performance for most consumer and industrial applications. Choose spiral bevel gears when: noise is a primary concern (3\u20136 dB(A) quieter than straight bevel at the same speed); load is higher (spiral bevel’s higher contact ratio gives better load capacity per unit size); or speed is higher (spiral bevel’s gradual tooth engagement reduces impact loading at speed). Korea Ever-Power supplies both; the standard catalogue is straight bevel; spiral bevel is available on custom order.<\/p>\n<\/div>\n

\n
\n

What is the operating temperature limit of plastic bevel gears?<\/p>\n

Korea Ever-Power’s standard plastic bevel gears (POM\/Nylon) are rated \u221240\u00b0C to +80\u00b0C for continuous operation \u2014 covering typical consumer electronics, automotive interior, food production, and general industrial ambient temperature ranges. For applications above +80\u00b0C, specify PPA (to ~120\u00b0C), PEEK (to ~250\u00b0C), or glass-fibre-reinforced PA66 (to ~130\u00b0C). Korea Ever-Power can supply plastic bevel gears in higher-temperature materials for under-hood automotive, oven equipment, and industrial high-temperature applications.<\/p>\n<\/div>\n

\n
\n

Can Korea Ever-Power supply matched plastic bevel gear sets (pinion + gear) at non-1:1 ratios?<\/p>\n

Yes \u2014 Korea Ever-Power supplies matched plastic bevel gear sets in ratios 1:1, 2:1, 3:1, 4:1, and 5:1 at modules M0.5 and M1 from standard catalogue stock. For non-standard ratios or modules, custom matched sets are produced per customer drawing. Matched set supply ensures that the pitch cone angles, module, and pressure angle are geometrically consistent \u2014 mismatched bevel gear sets from different sources produce incorrect cone apex alignment and accelerated tooth wear at the misaligned contact zone. Contact Korea Ever-Power<\/a> with your ratio and module requirement.<\/p>\n<\/div>\n<\/div>\n
