Precision Small Module Gear Shaft

As a core power transmission component in micro-drive systems, this part features an integrated design with a cylindrical shaft and external spur gears. It is commonly used in the reduction mechanisms of power tools, home appliances, and automation equipment. One end is configured with a square drive head or positioning step for torque connection to motor rotors or couplings, while the other end retains a smooth shaft section to accommodate bearing support, ensuring radial stability and low-noise performance during rotation.

Manufacturing such small module gears requires strict control over gear profile machining accuracy and heat treatment hardness to prevent wear or tooth breakage under high-load conditions. The coaxiality of the central bore relative to the outer diameter and gear teeth directly affects operational smoothness after assembly and is typically controlled within micron-level tolerances. For complex structures with square heads or异形 shafts, turn-mill compound machining processes are involved, strictly ensuring positional accuracy of feature surfaces and deburring quality to avoid sharp edges that could affect assembly feel or damage mating parts.

Dongguan Kangle Precision Technology relies on CNC machining centers, surface grinders, and gear meshing testers to perform refined manufacturing of such precision rotary parts from raw material to finished product. The factory is certified with IATF16949 and ISO 9001, possessing comprehensive gearbox component integration capabilities. We utilize automatic image measuring instruments for 100% inspection of key dimensions to ensure consistency in batch delivery. Combining powder metallurgy (PM/MIM) and precision machining production lines, we support one-stop solutions including material selection, gear profile machining, and surface treatment according to drawing requirements.
