The cam indexer is a kind of intermittent transmission machine. Many people who don't know it will think that the internal structure of the cam indexer will be very complicated. The insider knows that the structure of the indexer is relatively simple, just the inside of the cam indexer. The complexity of the cam surface is mainly reflected in the processing of the cam itself. The indexing cam mounted in the input shaft is connected with the output shaft tower, and the cam roller is radially embedded in the circumferential surface of the output shaft tower, and the dimensional support of the cam is supported. The ribs make linear contact on their respective bevels.
  During the use of the cam indexer, in the case where the input shaft of the indexer rotates, the cam roller rotates out of the force shaft according to the displacement curve on the cam while simultaneously rolling along the inclined surface of the rib. In the region where the ribs are balanced with the end faces of the cams, that is, in the static energy range, the rollers are connected to their axes, but the output shaft itself does not rotate. The dimensional support ribs of the same portion are simultaneously in contact with two or more rollers, so that the rotation of the input shaft can be uniformly transmitted to the output shaft. This produces smooth and smooth intermittent motion. Very much about the problem of cam-drive dynamic-to-static ratio. I am concerned with the proportion of time in the dynamic and static conditions of the cam indexer during use.

  Then, since the inside of the indexer is a more complicated curved surface drive, the cam indexer can be generated in the case of rough machining or wear during use, if the cam surface of the dimensional support rib and the cam roller There is a non-slip condition between them, and the cam indexer will be damaged. By rotating the eccentric bearing seat that supports the input shaft and adjusting the distance between the input shaft and the output shaft, the phenomenon of non-slip can be completely eliminated. In the use, pay special attention to the accuracy measurement of the product itself and the change of noise. Most engineers adjust the preloading load to close the elastic area of ​​the cam roller and cam, thus strengthening the rigidity of the cam indexer.
  The simplicity of the principle structure of the indexer does not mean that it is simple to use. On the contrary, from the perspective of accuracy, it must be strictly in accordance with the product specification and the manufacturer's requirements. In addition, during use, Pay attention to its maintenance and maintenance.
