do you know the cam and groove coupling had been widely used in what application areas ?

　　The first application area: generally speaking, when we go to the market to choose some cam and groove coupling , you should according to your actual requirements to confirm, for example, if the movement rule of the valve stem is different, then the shapes of the cam and groove coupling would be different too. For example, when the cam contour has a radius vector change, and when the cam and groove is working, it had to flat bottom contact with the valve stem, then the motion action of the valve stem would be the advance and return movement, so you should choose the cylindrical cam; but when the centre of gyration of the cam is the circular arc of the circle, and when the circular arc section contour had contact with the valve stem, then the valve stem would be static without no actions, so with the continuous rotation moving of the cam and groove coupling , the valve stem can have an intermittent regular exercise, it would just like you had planning the curtain expected rule, you need to pay more attention about this factor;

　　The second application area: when the type of the cam and groove couplings are the cylindrical cam and groove coupling , the under the effect of the sides of the groove, the follower would be swing at the same time too, then after the follower is swing, the knife rest, which connect with the follower would be swing too, then the whole cam and groove coupling can be efficient working. But as the professional cam and groove coupling manufacturer, we need to attention you that the main factor which can influenced the movement rule of the knife rest is the shape of the grooves, so you need to take account more about this problem.
