About driving pulley / Belt conveyor -15

Belt conveyor moves its conveyor forwards and transports objects by turning pulley (roller) wound conveyor belt around it. There are two main driving method to transmit power and turn pulley.

1. Motor pulley (roller)

Motor is set inside of pulley (roller) and conveyor belt move forwards by just turning the power on. Conveyor with black rubber belt that we can get in marketplace is conveyor with motor pulley. However, there are few choices in external diameter for motor pulley, and one with large external diameter can be hardly found. Therefore, strength of conveyor belt needs to be less than 160N/mm and large belts which have thickness and strength are not used.
Other than the above, motor roller is used in roller conveyor which transports objects by turning multiple rollers put side by side. Motor roller used in belt conveyor has larger external diameter and rotational power compared with rollers used in roller conveyor.
Rotational speed is constant and the speed can be changed by invertor.

 

2. Motors

1)Roller chain, or V belt
Motor and pulley are attached separately and connected with roller chain or V belt, then conveyor belt is moved forwards by turning pully.
Roller chain and V belts are connected each other while they are attached to both of motor and pulley (roller), and pulley (roller) rotates when motor moves.
By turning pulley, conveyor belt moves forwards and objects can be transported.
Rotation speed can be changed by changing ratio of external diameter of sprocket wheel to V pulley. It can also be changed by invertor.

2) hollow shaft motor
Hollow shaft is used as shaft of pulley (motor), and conveyor belt moves forwards when motor turns and pulley rotate.
Rotational speed is constant and the speed can be changed by invertor.
