Background

A cam refers to a mechanical rotary or sliding member (such as a wheel or a projecting portion of a wheel) which transmits motion to a roller moving against its edge or to a needle bar moving freely on a grooved surface, or which is subjected to forces from such a roller and needle bar. The cam follower can be designed to satisfy almost any input-output relationship over its range of motion-for some applications, the cam and linkage can function the same (the trade-off between them is often designer-specific-translator-specific), the cam is easier to design than the linkage for both possible uses, and the cam can do many things the linkage cannot do, on the other hand, the cam is easier to manufacture than the linkage.

Cam seat is often used in textile industry, and cam seat's main function lies in fixed camshaft, and along with the development of science and technology, current cam seat majority adopts aluminum alloy material to make, possesses fine wear resistance, and this type of cam seat is integrated into one piece processing usually, though stable in structure, but the processing technology is comparatively complicated, and when a certain department of cam seat damaged, leads to whole cam seat can not normal use, is unfavorable for the enterprise to develop.
