The cam splitter is a high-precision and simple structure intermittent motion device (). Recently, many friends have called to inquire about the meaning of the cam splitter. Today, Xiaobian takes this opportunity to share with you the knowledge of the stop-and-go ratio.
First, the dynamic stop ratio is also called the dynamic and static ratio, which refers to the ratio of the rotation time to the stop time when the output end face of the cam splitter completes a station. Simply put: the ratio of the time to turn a station to the time required to stop at this station. For example: we turn a station for 1 second, and we need to stop for 3 seconds at this station, then the ratio is 1:3.
Second, the driving angle and the stopping angle: the driving angle refers to the input shaft (input shaft) rotating a certain angle to drive the output shaft (output shaft) to complete an indexing movement (one station movement). The stop angle refers to the angle at which the input shaft rotates when the output shaft (output shaft) is stationary. The sum of these two angles is 360Â°, that is, one turn.
Third, in general, the input shaft rotates once, and the output shaft completes all the movements and stops of a station. For example: the rotation station time is 1 second, the station stops for 3 seconds, the movement stop ratio is 1:3, the drive angle and stop angle reflected on the input shaft are also 1:3, and the drive angle can be calculated as 90Â°. The stop angle is 270Â°.
Fourth, of course, when the driving angle is too small (<90Â°), the motion stability is worse. We can stop the motor to extend the stopping time. If the previous example is changed to 1 second for 5 seconds, then the motor should be stopped. .
The dynamic stop ratio of the cam splitter is a comprehensive result determined by the customer's needs. The customer can also select the principle after understanding the principle. The examples are only illustrative. The specific problems should be analyzed in detail. The requirements of each device are not necessarily the same. If in doubt, you can call for detailed consultation.
