PulleyIt can be drum or drum type, and is the most common simple machine used to drive the belts of most conveyor systems.

 Due to its widespread use, manufacturers have improved it to obtain better system performance and longevity.One of these belts is the pulley of the crown.Pulleys are tubular rollers used to drive belt conveyor systems.The drive pulley is connected to the engine, so it can transmit the torque required for the steering belt.As a result, the conveyor belt moves along the way.However, due to its mechanism, a common problem with most conveyor belt wheels is that the conveyor belt tends to move laterally or away from its assumed track.When this happens, the belt will wear excessively due to friction with the frame material, in fact, it is rapidly deteriorating.In addition, the friction caused by friction, in turn, leads to an increase in the training load and power consumption of the engine.This is the role of the crown pulley.They are installed to ensure Pulley It is on the track, not drifting sideways.

Regardless of whether it is conical or trapezoidal, the crown pulley is composed of a drive wheel whose center diameter is slightly longer than the ends.The difference in diameter causes the belt to fix constant motion back to its track because it tends to move away.However, the disadvantage is cost.The material itself and the processing process make it a bit expensive.At present, heavy metals are used for the wall of the crown.And in the process, a lot of unusable materials are wasted. As a conveyor belt, the drive pulley tends to slip. This prompted manufacturers to develop smaller diameter drive pulleys.However, due to the smaller diameter, there is less contact with the surface of the conveyor belt.This, in turn, will result in limited torque transmission.In order to solve this problem, engineers believe that molding rubber or some synthetic materials on the surface of the drive wheel can increase adhesion, which is actually the transmission of torque.The rubber coating is what they call it.

The train provides the traction required for the pulleys to work more efficiently.The rubber material is compounded and applied to the pulley.The manufacturer makes vulcanized encapsulation of different hardness according to the customer's specifications, in any size or length.There are different models to choose from-plain ceramic crowns, herringbone patterns and grooves.However, this can be expensive.The cost of putting rubber on the drum and the material itself is relatively high.There is a cheaper alternative to the train, which includes a package at the back.The result is a crown effect on the pulley.The disadvantage of this type of delay is the effect of stretching Pulley,.
