Description

Technical Field

[0001] This utility model belongs to the field of bearing disassembly technology, specifically relating to a bearing remover for a conveyor rotating component. Background Technology

[0002] In the maintenance and replacement of rotating components of light-load conveyors, the traditional methods for disassembling and removing seated bearings are as follows: 1) Using a hammer and pry bar to punch out the gap in the base, and then prying it off along the gap; 2) Using a common puller to hook the bearing seat for forced disassembly. Both of these methods involve strong force transmission such as hammering, prying, pressing, and pulling during the disassembly of seated bearings. This inevitably causes irreversible damage such as scratches and deformation to the bearing balls, bearing shells, rollers, and mechanical equipment frames. Moreover, the disassembly is time-consuming and inefficient.

[0003] While Chinese utility model patent application number 201621468003.9 discloses a bearing extractor, it is used to remove bearings from fan shafts. During extraction, a combination of claws grips the outer ring of the bearing, and a hook structure holds the bearing in place. The bearing is removed by utilizing the opposing motion of the rotating push rod and the claws. The problem is that the clamping component of the bearing extractor is fixed to the outer ring of the bearing. This structure is suitable for fans, which are rarely corroded. However, in light-load conveyors, the rollers of rotating components often corrode together with the inner ring of the bearing. Removing the bearing by gripping the outer ring can easily damage the bearing. Therefore, this device is not suitable for removing bearings from rotating components of light-load conveyors.

[0004] Therefore, developing a bearing remover for conveyor rotating components is crucial for disassembling bearings without damage and improving bearing removal efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the series of defects caused by the need for manual disassembly of the bearings on the rotating parts of light-load conveyors, which requires strong disassembly by hammering, prying, pressing, and pulling. This utility model provides a bearing remover for the rotating parts of conveyors.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A bearing remover for a conveyor rotating component includes a fixing sleeve for fixing the inner ring of the bearing, a pry bar socket disposed on the side wall of the fixing sleeve, a threaded push rod inserted into the fixing sleeve and threadedly connected to the fixing sleeve, and a pry bar.

[0008] As a further technical solution, one end of the crowbar is inserted into the crowbar socket, and the other end is positioned outside the fixed sleeve.

[0009] As a further technical scheme, the fixed sleeve comprises a barrel, one end of the barrel is provided with a threaded sleeve, the other end is provided with one or more adjusting openings, mounting plates are arranged on the two sides of the adjusting openings, and the two mounting plates on the two sides of the adjusting openings are connected through bolts.

[0010] As a further technical scheme, a threaded hole is arranged at one end of the barrel close to the adjusting opening, and a locking jackscrew is arranged in the threaded hole through threads.

[0011] As a further technical scheme, an annular groove is arranged on the inner ring wall of the threaded sleeve, and the barrel is inserted into the annular groove and fixedly connected with the annular groove.

[0012] As a further technical scheme, the adjusting openings are two, the barrel is formed by two half barrels, and the two mounting plates on the two sides of the adjusting openings are arranged on the two half barrels respectively.

[0013] As a further technical scheme, the threaded jackscrew is provided with a mounting handle at the end away from the fixed sleeve.

[0014] As a further technical scheme, the mounting handle adopts a hexagonal screw head.

[0015] Compared with the prior art, the beneficial effects of the utility model lie in:

[0016] 1. The fixed sleeve is connected with the bearing inner ring, and a crowbar insertion opening for inserting a crowbar is arranged on the fixed sleeve, so that when disassembling, the bearing inner ring is fixed with the fixed sleeve, the crowbar is rotated back and forth first, the high torque brought by the crowbar drives the bearing inner ring to rotate, the rust between the bearing inner ring and the roller shaft of the light load conveyor rotating part is broken and polished, and damage of the bearing and the mechanical equipment caused by rusting of the bearing inner ring and the roller shaft of the light load conveyor rotating part when the shaft is pulled out of the bearing is avoided.
