Precision Metal Spur Gear Assembly

Designed to meet the power transmission needs of micro-drive systems, this component features an integrated structure with a disc-shaped body and external spur teeth. The center incorporates a drive journal with internal threads. This design is commonly used in the primary or secondary meshing stages of reduction motors or automation equipment. The threaded shaft end enables rigid locking with rotors or couplings, ensuring stable torque transmission during high-speed operation.

The core of manufacturing lies in ensuring the precision consistency of tooth profile parameters (module, pressure angle) and surface finish to reduce noise and wear during multi-stage meshing. Strict control of the coaxiality between the central journal and the tip circle is essential to prevent scraping or vibration caused by eccentricity. The position tolerance of weight-reduction holes around the wheel body must be maintained to optimize moment of inertia and preserve dynamic balance performance.

Leveraging CNC turn-mill composite machining centers and gear meshing testers, Dongguan Kangsile Precision Technology provides full-process manufacturing from blank forming to finishing for such rotary parts. The factory is IATF16949 and ISO 9001 certified, equipped with automatic vision measuring machines and 3D contour measurers. We perform strict 100% inspection on key tooth profile errors, bore tolerances, and geometric deviations, meeting the high reliability requirements for core transmission components in power tools, smart home devices, and industrial modules.
