Rapid dismounting device for bearing of supporting shaft of armor belt coal feeder and use method for rapid dismounting device

Abstract

The invention is suitable for the technical field of coal instruments, and provides a rapid dismounting device for a bearing of a supporting shaft of an armor belt coal feeder and a use method for the rapid dismounting device. The rapid dismounting device comprises a lead screw, one end of the lead screw penetrates through a leveraging assembly and then abuts against the supporting shaft fixedly connected with the bearing, a thrust assembly is arranged on the side, away from the leveraging assembly, of the bearing, a connecting part is arranged between the leveraging assembly and the thrust assembly, the leveraging assembly and the thrust assembly are connected to a base in a sliding mode, and an adjusting part is arranged on the thrust assembly. Therefore, the rapid dismounting device and the use method thereof have the advantages that it can be guaranteed that the thrust applied to the bearing is in the same direction and is uniform, the bearing can be smoothly dismounted, the situation that the bearing dismounting difficulty is increased due to the fact that the direction of the force deviates can be avoided, bearings of various sizes can be dismounted, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of coal equipment, in particular to a quick dismounting device for a support shaft bearing of a belt coal machine and a method for using the same. Background technique [0002] Since the supporting shaft bearings of the A-belt coal feeder have been in a humid environment with a lot of foreign matter such as coal slag for a long time, the service life of the bearings is short, and the bearings are replaced frequently. When replacing the bearings, the bearings need to be disassembled first. The methods include tapping method, pulling method, and thermal removal method. The force of the knocking method is generally applied to the inner ring of the bearing, which is easy to damage the bearing; the pulling method is to use a special tool to hook the inner ring of the bearing, which is easy to cause the pulling direction to deviate or the pulling force to be too large when pulling out the bearing. It is also easy...

AI Technical Summary

Problems solved by technology

The force of the knocking method is generally applied to the inner ring of the bearing, which is easy to damage the bearing; the pulling method is to use a special tool to hook the inner ring of the bearing, which is easy to cause the pulling direction to deviate or the pulling force to be too large when pulling out the bearing. It is also easy to damage the bearing; the hot disassembly method is complicated to operate, and the structure of the device used is also relatively complicated, and it is easy to cause safety hazards

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
