How to determine the sprocket of the chain driven roller conveyor

First determine the drum diameter and installation distance, and determine the torque according to the size of the goods 1. Select the gear motor first, determine the torque speed, reduction ratio and other parameters, select the same driving wheel and passive wheel, and the deceleration is all handed over to the gear motor; 2. According to the speed of the load chain Select the chain specification; 3. Select the size of the sprocket according to the position of the sprocket motor, considering factors: chain specification, installation space, sprocket wrap angle, etc. Generally, 17-21 teeth are enough.low number of teethSprocketSmall, polygonal effect leads to unstable transmission, and the number of teeth takes up space; 4. Select sprocket shaft and installation method, general clearance fit, flat key connection + set screw; 5. Draw a picture and find a factory for processing.The material and surface treatment can refer to the design manual.You can also buy a similar one in the market, and the chain drive has high fault tolerance.
