Precision Machined Double Gear Disc

As a core torque transmission component in power transmission systems, this double gear structure achieves rigid meshing with mating gears or racks through two-stage involute tooth profiles (internal and external). The center features a precisely machined through-hole and keyway interface for a secure connection to the drive shaft, ensuring smooth power output under high-speed rotation or heavy-load conditions. It is widely used in automated conveyor lines, industrial reducers, and precision mechanical transmission modules.

The core of manufacturing such parts lies in strictly controlling tooth profile accuracy, tooth direction deviation, and tooth surface roughness to reduce meshing noise and extend service life. For the thick-walled disc characteristics shown, it is crucial to control the coaxiality of the inner hole relative to the outer circle and the flatness of the end face to prevent radial runout or concentrated contact stress after assembly. The machining process typically involves turning reference surfaces, milling tooth profiles, and subsequent heat treatment and precision grinding, requiring high standards for tool path planning and clamping rigidity.

Leveraging high-precision vertical machining centers and CNC lathes at our Dongguan facility, combined with Coordinate Measuring Machines (CMM) and gear inspection instruments, we ensure closed-loop control of critical dimensions and geometric tolerances, guaranteeing consistency in batch deliveries. Buyers need to provide 2D/3D drawings specifying material grades (such as #45 steel, alloy steel, or stainless steel), module, pressure angle, heat treatment hardness requirements, and surface finish standards. We evaluate costs and lead times based on drawing complexity, material utilization, and inspection standards, supporting full-cycle services from single-piece prototyping to large-scale mass production.
