Turning conical conveyor roller
The driving drum is composed of shaft, bearing seat, spoke plate and barrel. The surface is covered with rubber to increase the friction coefficient between the driving drum and conveyor belt. The bearing seat is equipped with self-aligning roller bearing to ensure the stability of support and flexible rotation. When the driving device is running, the torque in the driving device is transmitted to the shaft of the driving drum, and then the shaft is connected through the internal expansion sleeve (or key) to transmit the torque to the cylinder. Due to the friction between the drum and the belt, the torque is transmitted to the belt to drive the operation of the whole belt conveyor. Conical double chain conveying roller can be divided into steel plate rolling and welding, cast steel and cast iron from the production material; assembly spoke plate, spoke type and integral spoke plate from the structural type; in addition, the roller surface can also be smooth, coated, cast rubber and other types; among them, steel plate welding assembly spoke plate cast rubber roller is widely used.
Maintenance method of conical double chain conveying roller:
1. The dust and other foreign matters on the transmission drum should be cleaned regularly;
2. For the drum shell and end cover welding is firm to do regular inspection;
3. It is necessary to keep the good lubrication of the transmission drum and reduce the damage of friction to the transmission drum;
4. It is necessary to avoid overload operation of transmission drum and prolong its service life.
