Precision External Spur Gear Disc

As a core drive unit in industrial reducers, automated conveyor lines, or heavy machinery power modules, this disc-shaped transmission component features standard involute teeth uniformly distributed along the outer circumference. It engages rigidly with mating gears or racks. The central through-hole and keyway structure facilitate torque transmission to the drive shaft. The overall design balances bending strength under high loads with rotational stability, making it suitable for power transmission scenarios with strict requirements for transmission precision and load-bearing capacity.

Manufacturing focuses on ensuring tooth profile accuracy, tooth direction deviation, and surface roughness to achieve low noise and long service life during engagement. For the thick-walled disc structure shown, strict control of coaxiality between the inner hole and outer circle, as well as端面 flatness, is essential to prevent radial runout or concentrated contact stress after assembly. For large-diameter gear discs, significant material removal requires reasonable allocation of machining allowances and the use of specialized fixtures to suppress deformation, ensuring dimensional consistency and interchangeability across batches in mass production.

Leveraging our Dongguan facility's expertise in precision machining, we are equipped with vertical machining centers, CNC lathes, and high-precision grinding equipment. We offer full-cycle services from single-piece prototyping to small and medium-batch delivery. By combining Coordinate Measuring Machines (CMM) with gear inspection instruments, we strictly control dimensional accuracy, geometric tolerances, and tooth surface quality of key mating surfaces. Buyers should provide 2D/3D drawings specifying material grades (e.g., #45 steel, alloy steel, or stainless steel), heat treatment hardness requirements, and key inspection points. We evaluate costs and lead times based on drawing complexity, material utilization, and post-processing techniques, supporting custom development from drawings.
