Product description
The influence of the radial runout of the load-bearing roller group on the belt conveyor: within the specified runout range, the belt conveyor can be kept running smoothly, otherwise it will cause the belt conveyor belt to resonate and jump, causing material toss and polluting the environment. The higher the belt speed, the greater the benefit of the smaller radial runout.
The amount specified in the Chinese standard is 0.7 mm, and the amount specified in the Japanese JIS standard is 0.5 mm.
The impact of the flexibility of the load-bearing roller group on the belt conveyor: During the operation of the belt conveyor, the flexibility of the roller is very important. If the roller is not flexible and the rotation resistance coefficient is high, the entire belt conveyor The system has to pay a lot of power, consume a lot of electricity, and sometimes cause the tape to tear, the motor burns, and in severe cases, it can cause a fire. Therefore, the selection of idlers with low rotation resistance coefficient (less than 0.020) is an important part of the design and selection of belt conveyors.
The impact of axial movement on the belt conveyor: my country’s belt conveyor manufacturing technology is increasing, but the axis movement is still a topic that needs to be studied, because my country’s belt manufacturing technology and belt conveyor installation technology are still in line with the world’s Larger gaps often cause the tape to deviate. If the amount of axial movement of the roller is large, it will cause early damage to the roller. Generally, it is better to control the axial movement within 0.5-0.7 mm.
There are five other criteria for judging the quality of rollers:
1. Dustproof performance of roller.
2. Roller performance.
3. The axial bearing capacity of the roller.
4. The impact resistance of the roller.
5. The service life of the roller.
