Aluminum Gear Housing

Aluminum gear housing is the core structural component of transmission systems. It houses gears, bearings, and shaft assemblies. It maintains the precise positional relationship between transmission shafts. Our aluminum gear housing serves industrial reducers, automotive transmissions, robot joint modules, and power tool drive systems. Compared to cast iron gear housings, aluminum gear housing significantly reduces weight. It also offers better heat dissipation. These benefits make it ideal for applications where weight and operating temperature are critical. Every aluminum gear housing we produce is built for accurate and reliable gear operation.

Aluminum gear housing machining presents one major challenge: maintaining center distances and position accuracy between bearing bores. These dimensions directly determine gear meshing quality. If bearing bore positions deviate too much, gears experience misalignment, noise, and abnormal wear. Our machining solution uses 5-axis machining centers with high-precision fixtures. We complete all bearing bores, mounting surfaces, and connection holes in a single setup. We use high-precision boring tools and electronic tool setters to ensure consistent bore dimensions. Our aluminum gear housing bearing bore position accuracy is controlled within ±0.02mm. Center distance deviation between bearing bores is within 0.025mm. Parallelism is within 0.02mm. These dimensions are verified by our HEXAGON CMM. Every product's inspection record is archived for future reference.

Quality control for aluminum gear housing goes beyond conventional dimensional inspection. We pay special attention to mounting surface flatness and thread hole perpendicularity. These factors directly affect gear housing assembly quality and sealing performance. We use pneumatic gauges to check thread hole pilot diameters. This ensures thread accuracy after tapping. For split line surfaces, we finish mill and then lap. Flatness is within 0.02mm. Surface roughness is Ra≤0.8μm. This guarantees effective sealing with sealant or gaskets. Every product undergoes visual inspection (6000K light) and full dimensional inspection. Only parts with QC PASS labels are packed for shipment.
