How to determine the sprocket of the chain conveyor roller conveyor

Generally determine the diameter of the drum, the installation spacing, and determine the torque according to the size of the cargo.

1. First select the Geared motor, determine the torque speed, reduction ratio and other parameters, the drive wheel passive wheel selection is the same, the deceleration is fully delivered to the geared motor;

2. Select the chain specification according to the load chain speed;

3. According to the sprocket motor position to choose the size of the sprocket, the considerations are: chain specifications, installation space, sprocket wrap angle, etc., generally choose 17-21 teeth enough. The number of teeth is small, the sprocket is small, the polygon effect causes the transmission to be unstable, and the number of teeth takes up space;

4. Select the sprocket shaft and installation method, generally the clearance fit, the flat key connection + the set screw
