Cams are very common in our lives, and of course, they play a very important role. Here's an introduction to the basic parameters of a cam. If you are interested in this topic, let's take a look together, hoping to help some relevant people.

Of course, the use of cams also brings many benefits. For example, a cam refers to a rotating or sliding mechanical component (such as a wheel or a wheel protrusion), which transmits motion in use to a roller moving along its edge or a needle bar moving freely on the groove surface, or from such rollers and needle bars. In recent years, this cam follower mechanism can be designed to meet almost any input-output relationship within its range of motion. For some purposes, cams and linkage mechanisms can serve the same purpose, so you need to know that for work that can be done by both, cams are easier to design than linkages, and can do many things that linkages can do. On the other hand, they are easier to manufacture than linkages. Current products are generally composed of three components: cam, follower, and frame, forming a high-score mechanism. Moreover, it usually rotates continuously at a constant speed, and the follower is designed according to the usage requirements, so that it can obtain a certain regular motion.

It can achieve complex motion requirements and is widely used in various automatic and semi-automatic mechanical devices. Almost any arbitrary motion can be generated through this mechanism. When using a cam, you also need to know that it can be defined as a mechanism with a curved or curved groove. By swinging or rotating, another component, the follower, can provide preset motion. Generally speaking, the path of the follower is mostly limited to the slide groove to obtain reciprocating motion. In its return stroke, it sometimes relies on its own weight, but some mechanisms often use springs as restoring force to obtain precise action, while others use guide grooves to make it move on a specific path. Now the main function of the cam is to make the follower complete various complex movements according to the needs of the work, including linear motion, swing, constant speed motion and variable speed motion. It can be seen in many places. For example, the motion law of the valve stem defines the profile of the cam. When the cam profile with different radii contacts the flat bottom of the valve stem, reciprocating motion occurs; when the arc segment profile centered on the cam rotation center contacts the valve stem, the valve stem will remain stationary.

That's all for the information about "Basic parameters of a cam", hoping it can help more friends. More exciting content will be brought in the next issue, remember to come and watch if you have time.
