Description

[0002] In a transmission system, a cam plate is a core component for converting rotary motion into reciprocating motion, and is widely used in automobile engines. The working principle is that the irregular profile on the outer periphery of the cam plate contacts with a follower to convert the rotary power of the camshaft into precise reciprocating displacement of the follower.

[0003] Traditional integrated cam plates are mostly solid structures with only a simple central hole, and have low functionality. Although the strength can be guaranteed, the weight is relatively large, and in high-speed scenarios, large inertial forces are easily generated, increasing the energy consumption and vibration noise of the transmission system. Some attempts at lightweight design have opened weight-reducing cavities. During the operation of the cam plate, cracks are easily generated at the edges of the weight-reducing cavities, shortening the service life. It is difficult to balance the requirements of lightweight and strength. In addition, during the pressing process of the cam plate and the camshaft, pressing jamming and surface scratches are easily generated, leading to an increase in the assembly failure rate.
