Speaking of the cam indexer angle, there may be no understanding of the indexer. Here is a brief explanation for everyone.
The angle of the indexer can be divided into the rotation angle of the output shaft and the rotation angle of the input shaft. For the output shaft, the rotation angle of the output shaft from the A-station to the B-station under the action of the input shaft is called the output. The displacement angle of the shaft. For example, for a 4-station indexer, when the output shaft rotates one revolution, the output shaft of the indexer will be displaced 4 times to 360 degrees per week, and each displacement angle is 90 degrees. Similarly, the displacement angle of the 2 stations is 180 degrees, and the output shaft reaches one revolution in the case of the rotational displacement twice.
The rotational displacement angle of the output shaft is the driving angle of the input shaft rotation. Because the indexer is the input shaft and the drive source, the output shaft rotates to drive the output shaft for intermittent motion. The process is the driving angle of the input shaft rotation. The movement of the input shaft is continuous rotation. When the output shaft stops, the rotation angle of the input shaft is called the angle of repose. According to the driving angle, the indexer runs. The more stable the principle, the rotation of the input shaft every revolution is the sum of the driving angle and the angle of repose. In the case where the driving angle is 270 degrees, then the angle of repose is 90 degrees.
The choice of the driving angle and the angle of repose of the indexer is inseparable from the requirements of the automatic system for intermittent motion. In the case of high speed operation, the driving angle will be relatively small. In the case of heavy load, the speed will be selecte. Large drive angle. For the non-intermittent indexer, if the servo or stepper drive is used to stop at any point, there is no drive angle and angle of repose, so the cam indexer is equivalent to a reducer.
