Ceramic Lagging- A Good Thing Can Be Costly If Misused Allen V. Reicks P.E., Timothy Mess ... Pulley torque is transferred to the conveyor belt as circumferential shear force between it and the belt. The classic equation states that the maximum permissible torque and therefore tension transfer is related to the slack side tension, the wrap and the limiting friction factor between the pulley ...

Get Price### Motion of a box in a conveyor belt - Physics Stack Exchange

The conveyor belt rollers being pulled along by the belt interact with the belt via static friction as their outer surfaces move at the same speed as the belt. This static friction will not change since the rollers are the load. Only a pulley driving the belt (via a motor) will experience an increase in torque, and thus interaction friction, as the box is dropped onto the belt.

The standard speed for most unit handling conveyors is 65 FPM (feet per minute) which works out to the average speed a person walks when carrying a 50-pound box. This pace is ideal for many—but not all—order picking and assembly operations. There are always situations where transport through an area, into a process, or toward a packing operation can be accelerated.

The angle of inclination (alpha) is used for the derivation, which results as the angle between the center line of the pulleys and the straight line of the belt. As the figure above shows, the inclination and the wrap angle (varphi) of the small pulley are related as follows (unless explicitly stated otherwise, the entire angle specifications and functions refer to the radians!):
