Micro Planetary Gear Assembly

The coordinate precision of the central bore and lateral countersunk holes directly determines the assembly concentricity and locking stability of this component within reduction mechanisms. The disc-shaped parts shown include a transmission wheel with external straight teeth and a flat mounting end cap. Commonly found inside micro motors or precision transmission modules, they respectively perform torque transmission and axial positioning support functions.

Manufacturing these transmission components requires strict control over module consistency, pressure angle precision, and tooth surface finish to ensure smooth operation and low noise during multi-stage gear meshing. The coaxiality of the bearing seat on the end cap and the positional tolerance of the side countersunk holes directly affect the radial runout of the rotor system, preventing rotor-stator rubbing or abnormal wear caused by eccentric loading. The fine texture of the metal surface typically results from precise deburring and grinding after CNC turning and milling, strictly avoiding sharp edges that could damage mating parts.

Dongguan Kangsile Precision Technology leverages CNC machining centers, surface grinders, and gear meshing testers to provide refined manufacturing from raw material to finished product for such precision rotating bodies with gear features. The factory is IATF16949 and ISO 9001 certified, equipped with automatic video measuring machines and 3D contour measuring instruments. We perform strict 100% inspection of key gear parameters, bore tolerances, and geometric errors to meet the high consistency demands of core transmission components in power tools, smart home drive modules, and automation equipment.
