Eccentric Gear and Cam Assembly

This transmission component integrates external spur gears with an eccentric cam profile, commonly used in valve timing or feed mechanisms for small powertrains and lawn mowers. The structure transmits rotational power through gear meshing while converting rotation into the reciprocating linear motion of a push rod via the asymmetric cam surface, ensuring precise timing control of mechanical actions.

Manufacturing such complex shaft components requires strict control over the positional accuracy between gear parameters and the cam lift curve. Our facility is equipped with CNC gear hobbing machines and specialized CNC cam grinders to ensure tooth form errors and profile tolerances meet drawing specifications. Critical journal fits are precision-machined using CNC cylindrical grinders to guarantee coaxiality and surface roughness, meeting wear resistance requirements for high-speed operation.

Taizhou Dingzhen Cam holds IATF 16949 quality management system certification and supports customized production using alloy steels such as 40Cr and 20CrMnTi. Depending on operating conditions, we offer quenching and tempering or carburizing and quenching processes to enhance core toughness and tooth surface hardness. We conduct full-dimensional inspections using CMMs, gear inspection centers, and pneumatic gauges, providing material reports and hardness data to ensure consistency in batch deliveries.
