How many pause positions does the cam indexer have? At the beginning of the design of the automation system, and for some engineers who want to carry out multi-station transmission design, they will think or ask this question, that is to say, how many stations can be designed as such a revolving device as a splitter .
The number of positions where the splitter pauses refers to the output shaft of the cam indexer used in the automatic transmission system. In the case of 360 degrees of rotation, the number of stops is also the number of turns of the output shaft, because in the splitter, Each time the input shaft rotates, the output shaft runs from the A point to the B point, that is, it stops once. In this case, it is only for the single-lead cams with less common working digits, generally below 16 stations. As shown in the figure below, it is a schematic diagram of the running curve of the single-lead splitter cam.

Here is a concept of "lead". The lead of the splitter cam means that in the cam, a spiral groove rotates 360 degrees around the cylinder, completes the splitter of the input shaft and stops the movement, and runs a station. Single lead cam. For multi-station high-speed splitters, it is necessary to complete intermittent motion with more than two-way multi-lead cams. The two-lead cams refer to the input shafts rotating at 360 degrees and the output shafts running two. Station. Other more and so on. As shown in the figure below, it is the running curve of the double-lead splitter cam.

The design of the splitter station is established when the output shaft rotates one revolution, and the circumference is 360 degrees. Therefore, the design number of the station must be divisible by 360 degrees to perform the sinusoidal processing of the cam, like the Kemide brand. The maximum can be 72 stations, that is to say, the number that can be divisible by 360 degrees below 72 stations is the number of work stations that can be done.
