Hello, engineers! While you are selecting the cam divider model, you will definitely choose the cam divider reducer reduction ratio, and today we take this opportunity to discuss the cam divider reducer reduction ratio.
According to the working condition of the customer's cam indexer, we know the rotation time of rotating the turntable to rotate one station. We already know clearly that the rotation time + rest time (default drive cam splitter motor continuous operation without stopping) = input shaft rotation time, since we know the input shaft rotation time, through the unit of conversion, it can be calculated that the input shaft revolutions are how much (the unit of rotation speed is rpm), calculated gearhead output revolutions, and then the motor revolutions divided by the output of the speed reducer. After calculating the speed reducer output, then divide the motor speed by the speed reducer output, then the speed reducer output will be the speed reduction ratio of the reducer. Need to add is that the rest time is calculated by the ratio of the rest angle to the drive angle. It's a bit confusing, right? Let's give you an example and you'll understand.
If the rotation time is 1 second, the rest time is 3 seconds. First of all, we have to determine the drive angle, static and dynamic time ratio is 1:3, then we choose the drive angle of 90 degrees, the stationary angle of 270 degrees, so right, as if there is no problem, in fact, there is a problem. As we said, the cam indexer drive angle the larger the smoother the operation, the drive angle of 270 degrees is best, 90 degrees is too small, it is best not to choose, otherwise the operation is not smooth resulting in jitter is the probability of phenomena. It is still recommended to choose the drive angle of 270 degrees. At this point you have another problem came up, the drive angle of 270 degrees, the stationary angle of 90 degrees, static ratio is not 3:1, not my initial 1:3 ah, you forget, we can stop the motor to extend the cam indexer of the rest time ah, that is, the rotation time of 1 second, the rest time of 1/3 seconds, and then by stopping the motor to extend the rest time to 3 seconds can be. Turning time 1 second + stationary time 1/3 second = input shaft rotation time, i.e., the input shaft rotation of a circle to 4/3 seconds, through the unit conversion, the input shaft rotation is 45 rpm, the cam splitter input shaft rotation is the output speed reducer, that is to say, the speed reducer output rotation is 45 rpm. Generally, the motor speed is 1400 rpm, the speed reducer ratio = motor speed divided by speed reducer output speed = 1400 divided by 45 = 31, the speed reducer speed ratio is close to 30, then the speed reducer ratio is 30.
