Advantages of the cam indexer

The indexer plays a large role in the real life. Then, there are not many people who know the advantages of the indexer. Here, we will briefly introduce the advantages of the indexer. 1. Compact structure, large transmission ratio, because there are only two basic components when the cam is driven, so that the number of indexing rollers is small, and the surfaces of the plurality of lead rollers are in meshing state, then the indexer is The cam drive can be compact in the case of large gear ratios. Through more stringent calculations, the first-order cam drive has a transmission ratio of 6:80 when transmitting power, and even the transmission ratio can reach 1500. The biggest advantage of such a transmission is that it can replace the multi-stage gear transmission. 2. The work is stable and the transmission precision is high. The cam surface designed by the designer is generally a spiral surface with a small angle of elevation. When the surface of the cam rotates at a high speed, the normal division speed on the cam will be small, so the cam transmission can be used. The roller is rotated by a rack that is seen as a low-speed translation. It is also because of this design, the cam drive will be in a relatively stable state, and the way of such curved surface transmission is more obvious than the general involute gear, and the transmission stability is improved, and there is another obvious The advantage is that the impact is low and low noise, suitable for high speed indexing. 3. The accuracy is improved, the error is reduced, because the cam surface is a continuous spiral surface, and the design of such a continuous spiral surface is relatively easy to obtain high processing precision, and the cam drive has a large degree of coincidence, then when used There is a homogenization of the cam manufacturing error, and it is precisely because of this that higher transmission accuracy can be obtained when using the indexer. 4. It can realize self-locking. For the self-locking use state, it can be said that the use effect of the indexer is greatly improved. Then, under what circumstances will the self-locking state occur, that is, when the cam spiral angle is smaller than that between the conjugate surfaces? At the equivalent friction angle, the cam drive reverse stroke will appear in a self-locking state. 5. Others, the advantage of the indexer is that the transmission torque is large, there is a wide range of motion and static ratio, product standardization, serialization and so on.
