1. The normal service life of the roller is more than 20000h, generally no maintenance is required. However, according to the size of the place of use and the load, the corresponding maintenance date should be established, the oil filling maintenance should be timely cleaned, and the floating coal should be cleaned in time. For rollers with abnormal sound and no rotation, change them in time.
2. When changing the bearing, make the bearing cage open outward. After the bearing is loaded into the roller, it should maintain proper clearance and must not be crushed.
3. The labyrinth seals should be made of original parts. They should be loaded into the rollers separately during assembly and should not be assembled together.
4. the use of the roller, should be strictly prevented from hitting the roller body.
5. In order to ensure the sealing performance and performance of the roller, it is forbidden to disassemble the roller at will.
6. The roller support device is convenient for the roller support device of the change roller, and relates to a deflectable roller support, a support, a pin, a fuselage, a roller, a limit block and a fastener. The lower end of the support is connected with the upper end of the fuselage by a fastener, and the support is connected with the deflectable roller bracket by a pin, and the idler roller bracket is provided with a roller. On the deflectable roller bracket, a card slot for rotating around the pin shaft is arranged, the roller is installed in the slot of the deflectable roller bracket, and the limiting block for controlling the deflection angle is arranged on the deflectable roller bracket .
7. A pin for rotating the deflectable roller bracket is arranged on the support or the fuselage. When the fastener is removed, the deflectable roller bracket can be horizontally fixed under the control of the limit block. The angle at which the pin rotates. The trough bracket is a type of roller bracket. Adopt advanced production technology to ensure product quality. The grooved roller belt is dipped, and the force is large on the slope belt, the resistance is small, and the effect is good. The double-section idler can reduce the heavy pressure point of the belt on the ceramic idler. The hollow device of the idler can make the belt drop by itself, and the suction roller can not extend the service life of the roller.
