Product Overview<\/h2>\n

\n \"Aircraft\n <\/div>\n
\n

The double helical gear<\/strong> form in aircraft applications is the engineering choice when a single helical gear’s axial thrust force would create an unacceptable load on the bearing arrangement of a compact aircraft mechanism. The helical gear has a transverse force on the shaft. To eliminate this force, the gear is made into a double helical gear \u2014 two helical tooth sets of symmetrically opposite direction on a common blank \u2014 stopping the net axial force. Viewed from above, the tooth grooves form the letter V; in quantity they produce the herringbone pattern. Korea Ever-Power’s aircraft double helical gears deliver high coincidence degree, small axial load, high bearing capacity, and stable operation \u2014 and adopt the double-helical form to transmit torque from the drive motor to the load shaft in the same way as industrial herringbone gears, but optimised for the lightweight, compact, and precision requirements of aircraft mechanisms.<\/p>\n

Standard example: \u03a68 mm, module M0.15\u2013M2.0, in any of the available materials including bronze, titanium alloy, aluminium, or stainless steel. Highly precise aircraft double helical gears<\/a> are produced to AGMA 13 \/ DIN 5 accuracy \u2014 the highest practical accuracy in the small-module, small-diameter range. ODM and OEM service. ISO 9001:2008 \/ RoHS certified. 24-month warranty.<\/p>\n<\/p><\/div>\n<\/div>\n

Korea Ever-Power has some stock items available with short delivery times; custom configurations are produced with a sample lead time of 5\u20137 days and production delivery of 25\u201330 days from order confirmation. The quotation response time is 24 hours for standard products and 48 hours for custom configurations requiring cost calculation. The 24-month warranty covers all products inspected under the factory QC process system before shipment; non-conformance response within 48 hours; compensation scheme implemented within 48 hours of complaint receipt.<\/p>\n

Material Selection Guide for Aircraft Mechanism Gears<\/h2>\n

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

Aircraft mechanism gear material selection is driven by three primary constraints: weight (aluminium and titanium alloys preferred for weight-critical applications), operating environment (temperature range, moisture, hydraulic fluid exposure, vibration), and electromagnetic compatibility (non-magnetic materials for avionics-adjacent gear trains). Korea Ever-Power’s broad material offering \u2014 11 standard options \u2014 covers the most common aircraft gear requirements.<\/p>\n

\n\n\n\n\n\n\n\n\n\n\n
Material<\/th>\nKey Property<\/th>\nAircraft Application<\/th>\n<\/tr>\n<\/thead>\n
Aluminium<\/td>\nLightweight (2.7 g\/cm\u00b3), non-magnetic, corrosion resistant with anodising<\/td>\nUAV payload drives, light aircraft instrument actuators, satellite mechanism gears \u2014 where weight is the dominant constraint<\/td>\n<\/tr>\n
Stainless Steel<\/td>\nCorrosion resistant, non-magnetic (austenitic), autoclave-compatible<\/td>\nAircraft galley equipment drives, avionics bay gear trains, helicopter hydraulic actuator gears in wet\/humid compartments<\/td>\n<\/tr>\n
Alloy Steel (hardened)<\/td>\nHigh strength, high fatigue life, compact gear size for given torque<\/td>\nFlight control surface actuator gears, landing gear drive mechanisms, turboprop engine accessory gear trains<\/td>\n<\/tr>\n
Bronze<\/td>\nSelf-lubricating against steel, corrosion resistant, non-sparking<\/td>\nAircraft fuel system gear drives \u2014 non-sparking property prevents ignition risk; corrosion resistant in aviation fuel environment<\/td>\n<\/tr>\n

Key Performance Features<\/h2>\n

\"measuring<\/p>\n

\n
\n

High Coincidence, High Bearing Capacity<\/h3>\n

The double helical form provides the highest contact ratio among external gear types. In aircraft mechanism drives where the weight and size of the gearbox must be minimised, the high bearing capacity of herringbone gears allows the same torque to be transmitted in a smaller and lighter gear package than spur gears of equal centre distance.<\/p>\n<\/p><\/div>\n

\n

Zero Axial Load<\/h3>\n

Elimination of axial load means the shaft bearings of aircraft mechanism gear trains need only accommodate radial loads. In a UAV payload actuator or flight control surface drive where the shaft support is a miniature bearing, this thrust elimination directly reduces bearing size and thus mechanism weight \u2014 an explicit advantage in the weight-sensitive aircraft application.<\/p>\n<\/p><\/div>\n

\n

Stable, Quiet Operation<\/h3>\n

Aircraft interior environments are noise-sensitive for passenger comfort; electronic rack environments require low vibration to avoid interference with precision instrument readings. The herringbone gear’s smooth, continuous tooth engagement and high contact ratio produce the lowest gear-generated noise and vibration among external gear configurations \u2014 without the weight penalty of vibration-damping coatings or housings.<\/p>\n<\/p><\/div>\n

\n

AGMA 13 Precision<\/h3>\n

AGMA 13 (\u2248 DIN 5) is the highest accuracy achievable in the M0.15\u2013M2.0 size range for machined metal gears. At this accuracy level, transmission error at the tooth mesh frequency is minimised \u2014 the gear pair delivers the closest approach to constant velocity ratio that is practically achievable in a manufactured gear set, which is the required property for precision aircraft actuator drives.<\/p>\n<\/p><\/div>\n<\/div>\n

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

Can Korea Ever-Power supply products not currently listed on the website?<\/p>\n

Yes \u2014 send the requirements and Korea Ever-Power will assess whether production is feasible. If production is not possible directly, Korea Ever-Power can act as a China sourcing agent to identify the appropriate manufacturer. This applies to aircraft mechanism gears in materials, sizes, or configurations outside the standard range, as well as to other precision mechanical components required alongside the gear set.<\/p>\n<\/div>\n

\n
\n

What certifications does Korea Ever-Power hold for aircraft gear supply?<\/p>\n

Korea Ever-Power holds ISO 9001:2008 and RoHS compliance certification. For aircraft component supply programmes requiring AS9100 or NADCAP certification, these are not currently held \u2014 customers whose programme requires AS9100 should confirm requirements at the enquiry stage so that the available documentation and quality assurance provision can be assessed against the programme requirement. ISO 9001:2008 certified production with 100% pre-shipment inspection and 24-month warranty is the standard quality assurance provision.<\/p>\n<\/div>\n

\n
\n

What is the warranty and warranty response process?<\/p>\n

The warranty period is 24 months before shipment \u2014 products are strictly inspected under the factory QC process system before dispatch. If any abnormality is found after receipt, the customer should contact Korea Ever-Power immediately. The customer complaint handling procedure activates at once: a reasonable resolution and compensation scheme is negotiated and the implementation is confirmed within 48 hours. This warranty applies equally to prototype and production quantities.<\/p>\n<\/div>\n

\n
\n

How is the product packed for air and express shipment?<\/p>\n

Standard packing is one piece per carry bag, suitable quantity per export carton, without additional packing accessories. Vacuum-packed in plastic tray packaging is also available \u2014 recommended for aluminium gears (to prevent surface oxidation during extended transit) and for any gear where moisture absorption or surface contamination during shipping must be prevented. Customer-specified packing is available and should be stated at the order stage. Shipment is by air, sea, or DHL\/UPS express per the customer’s requirement.<\/p>\n<\/div>\n

\n
\n

Why should I choose Korea Ever-Power for aircraft double helical gears?<\/p>\n

Korea Ever-Power takes customers’ requirements as the mission and carefully addresses each specification. The 11-material option range (metal, bronze, steel, alloy, POM, zinc, aluminium, iron, stainless, brass, copper) in the M0.15\u2013M2.0 size range at AGMA 13 accuracy gives aircraft component buyers access to a wider material and accuracy combination than is available from most specialist small-gear suppliers.
