Spline Spur Compound Gear

Featuring a multi-tooth spline structure in the central bore and precision involute spur teeth on the outer circumference, this dual-meshing design is commonly used in power transmission links for micro reduction motors or planetary gearboxes. The internal spline ensures rigid, high-torque connection and anti-rotation positioning with the drive shaft or coupling, while the external teeth transmit power to the next stage of the transmission mechanism, ensuring concentricity stability and efficient power output during rotation.

Manufacturing such compound gears requires strict control over the relative position and coaxiality between the internal spline and external teeth to prevent meshing impact, rotor-stator rubbing, or abnormal noise caused by eccentricity during high-speed operation. Surface finish and deburring quality directly affect wear resistance and assembly feel; therefore, processes typically include precision turning, hobbing, and fine grinding. For mass production, consistency in tooth profile parameters (such as module and pressure angle) is strictly monitored to ensure smooth engagement in multi-stage gear systems.

Dongguan Kansile Precision Technology leverages CNC machining centers, surface grinders, and gear meshing testers to provide refined manufacturing from raw material to finished product for these precision rotating components with complex tooth profiles. The factory is IATF16949 and ISO 9001 certified, equipped with automatic video measuring machines and 3D contour profilers. These tools enable rigorous full inspection of key tooth profile errors, bore tolerances, and geometric deviations, meeting the high reliability demands of core transmission parts in power tools, smart home appliances, and automation equipment.
