Micro Gearbox Housing With D-Shape Output Shaft

Featuring a cylindrical black metal casing and a protruding flattened drive shaft, this assembly functions as the structural backbone for micro reduction mechanisms. The front flange integrates a precision bearing seat to support the output axis, while side slots facilitate the axial locking of internal stator components, ensuring stable torque transmission in compact spaces.

Manufacturing precision focuses on the concentricity between the front bearing bore and the rear support structure to minimize radial runout and vibration during high-speed rotation. The D-shape profile of the output shaft requires strict symmetry control to guarantee secure coupling with pulleys or linkages, preventing slippage under load. Surface treatment consistency is also critical to maintain corrosion resistance and dimensional stability within tight assembly tolerances.

Dongguan Kangsile Precision Technology leverages CNC machining centers and gear meshing testers to produce such transmission housings with high repeatability. Certified to IATF16949 and ISO 9001, the facility utilizes automated optical inspection systems to verify critical features like shaft dimensions, hole positions, and surface finish. This ensures that each unit meets the rigorous reliability standards required for electric tools, home appliances, and automotive actuators.
