                  Introduction of driving wheel and driven wheel of belt conveyor line

                  Information summary:

                  The belt drive pulley is a roller that directly receives the torque transmitted by the motor drive system (motor + gearbox + drive belt, chain, timing belt, etc.) to drive the movement of the conveyor belt. The driving wheel relies on the friction force generated by contact with the inner side of the conveyor belt to drive the belt. The axle of the belt line driving wheel and the hub are generally fixed (key connection or directly made into a part), and this axle is connected with the output shaft of the motor drive system (key connection, keyless connection or direct connection). Use couplings, etc.).


                          The driven wheel of the belt line does not directly drive power, but only plays the role of structural support and changing the direction of the belt line. It moves with the belt line, so it is also called the follower wheel and the reversing wheel. In terms of structure, the belt line driven wheel can be made into a fixed shaft (connected with the bracket), the hub and the shaft are connected through a bearing, so that the shaft and the hub can rotate freely; it can also be made into a shaft and the hub connected as a whole , And the shaft and the bracket are connected by a bearing. This structure is similar to the driving wheel (in this way, the shaft of the belt line driven wheel is shorter, thinner and simpler than the shaft of the driving wheel, because it is only a rotating shaft, not transmission shaft). Among them, the former method is more conducive to reducing the moment of inertia of the entire system, and is suitable for use in larger and more complex occasions. The latter method, because its structure is almost the same as that of the belt line drive pulley, has the advantages of simple design and manufacture. For the belt line in the automation equipment of the electronics industry, because the belt is thin and the weight of the workpiece is small, the moment of inertia is generally not a problem. , So it can also be used.
