The roller is an important part of the belt conveyor, with many types and large quantities. The function is to support the belt, reduce the running resistance of the belt, and make the belt straightness not exceed a certain limit to ensure the smooth running of the belt.
The rollers are classified into self-aligning rollers, buffer rollers, trough rollers, and parallel rollers according to their uses. The function of the self-aligning roller is to correct the deviation of the belt conveyor. Usually, a rotary groove-shaped self-aligning roller is installed on the heavy-duty section of the conveyor, and a parallel self-aligning roller is installed on the no-load section. The buffer roller is applied to the tailstock according to the actual situation. When receiving the material, it may reduce the impact of the material on the belt, which is beneficial to prolong the service life of the belt. The trough-shaped roller is generally composed of two side rollers and a flat roller. The groove angle is generally 35 degrees. For a detachable belt conveyor, the three rollers of the trough-shaped roller are hinged to each other, so Called hinged roller. The parallel roller is generally a long roller, which is installed at the lower end under pressure, so it is called the lower roller.
2.1. The normal service life of the roller is more than 20000h, and generally does not need to be repaired. However, according to the place of use and the size of the load, the corresponding maintenance date should be established, and the oil injection maintenance should be cleaned in time, and the floating coal should be cleaned in time. The rollers with abnormal noise and non-rotating should be replaced in time.
2.2. The labyrinth seals should be made of original parts, and should be put into the supporting rollers when assembling, and should not be assembled together.
2.3. During use, the roller should be strictly prevented from hitting the roller tube by heavy objects.
2.4. In order to ensure the sealing performance and use performance of the roller, it is forbidden to disassemble the roller at will.
