Driving pulley is the main part for transmitting the power. As per the different carrying capacities, The driving pulley can be divided into three categories: light duty, medium duty and heavy duty. And for the same diameter of the pulley, there are many different axle diameters and central spans. - Light-duty:
Bearing Aperture: 80~100mm.
The axle and the hub are connected by the single key. And it’s single plate welding. The axle is unidirectional out.
- Medium-duty:
Bearing Aperture: 120~180mm.
The axle and the hub are connected by the ring lock.
- Heavy-duty:
Bearing Aperture:: 200~220mm.
The axle and the hub are connected by the ring lock. The shell body is aluminothermic welding fabric. The axle can be unidirectional and two-way out.
The surface treatment of the driving pulley can be smooth steel, herringbone or rhombic rubber lagging.
- The smooth steel pulley is available for the place which environment is small power, small belt width and dry.
- The herringbone rubber lagging has a big friction factor, better anti-slippery and drainage ability, but it has its own direction.
- The rhombic rubber lagging is available for two-way operating conveyors.
- The vulcanized rubber lagged pulley are mostly used for important applications
The bearing housing of the pulley is lubricated by grease cup style lubrication. |
