Cam follower is a mechanism that the rotary motion or reciprocating motion of the cam drives the follower to perform specified reciprocating movement or swing. Cams have curved profiles or grooves, including disc cams, cylindrical cams and moving cams. The groove curves of cylindrical cams are spatial curves, so they belong to spatial cams. Now let's look at the classification of cam followers according to their shapes:

Classification by cam follower shape:

1.Tip cam follower: The tip of the follower can keep in contact with any complex cam profile, so that the follower can achieve any rule of motion. This kind of follower is simple in structure, but easy to wear at the tip, so it is only suitable for occasions with low speed and small force transmission.

2.Roller cam follower: In order to reduce friction and wear, a roller is installed at the end of the follower to change the sliding friction between the follower and the cam into rolling friction. Therefore, the friction and wear is small, and it can be used to transmit greater power. Therefore, this type of follower is widely used.

3.Flat bottomed cam follower: the follower is in line contact with the cam contour, and the contact is easy to form an oil film, with good lubrication. In addition, when the friction is not considered, the force exerted by the cam on the follower is always perpendicular to the flat bottom of the follower. The force is stable and the transmission efficiency is high, which is often used in high-speed occasions. The disadvantage is that the cam contour matched with it must be all convex.

4.Curved cam follower: In order to overcome the shortcomings of the tip follower, the end of the follower can be made into a curved surface, which is called a curved follower. This type of follower is widely used in production.
