Description

Frock is dismantled to bearing

Technical Field

The utility model relates to a bearing disassembly tool, and belongs to the technical field of mechanical tools.

Background

In mining operations, machinery often requires maintenance, repair, wherein the repair of the machine shaft requires the disassembly of bearings on the machine shaft. The existing bearing dismounting mode is to cut off the bearing by adopting the gas cutting for the fire operation, if precise equipment such as a scraper pump and a motor needs to be dismounted, the bearing can not be cut off by adopting the gas cutting for the fire operation in order to protect the equipment, and only the bearing can be scraped and taken down by a flat shovel, so that the damage of a mechanical shaft is easily caused in the bearing dismounting process, and the use of the equipment is influenced.

Therefore, a bearing disassembly tool is needed.

The utility model aims at the defects in the prior art, and provides a bearing dismounting tool which is suitable for dismounting and maintaining a bearing of a mechanical shaft of precision equipment and is not easy to damage the mechanical shaft.

The technical scheme for solving the technical problems is as follows:

a bearing disassembly tool comprises a jacket and a jacking mechanism; the jacket comprises two half jackets which are oppositely arranged, the two half jackets are detachably connected, a limiting table is arranged at the end part of each half jacket, the jacking mechanism is arranged between the two half jackets and comprises a jacking bolt and a limiting block, the limiting block is sleeved on the jacking bolt and is in threaded connection with the jacking bolt, a limiting hole is formed in each half jacket, and the limiting hole is matched with the limiting block in size.

The beneficial effects of the utility model are as follows: according to the utility model, the top pull bolt and the limiting block are enabled to generate relative movement by rotating the top pull bolt, the limiting block drives the jacket and the top pull bolt to generate relative movement, and the limiting table of the jacket pulls the bearing, so that the relative movement of the bearing and the mechanical shaft is realized, and the bearing is disassembled. The utility model has simple structure and convenient operation, and effectively avoids the damage of violently dismantling the bearing to the mechanical shaft.

Based on the technical scheme, the utility model can also make the following improvements:

further, a mounting nut is arranged on the limiting block, the mounting nut is in threaded connection with the jacking bolt, and a through hole for the jacking bolt to pass through is formed in the limiting block.

Further, the end part of the jacking bolt is provided with a jacking block.

Further, the material of the top pressing block is rubber, silica gel, TPU or sponge.

Further, the left side and the right side of the half jacket are respectively provided with a connecting ring, and the two half jackets are detachably connected through a fastening nut and a fastening bolt fastened on the connecting rings.

Further, the limiting table is a crescent plate

Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

Referring to fig. 1-2, a bearing disassembly tool comprises a jacket and a jacking mechanism; the jacket comprises two half jackets 1 which are oppositely arranged, the two half jackets 1 are detachably connected, a limiting table 2 is arranged at the end part of each half jacket 1, a jacking mechanism is arranged between the two half jackets 1 and comprises a jacking bolt 3 and a limiting block 4, the jacking bolt 3 is sleeved with the limiting block 4, the limiting block 4 is in threaded connection with the jacking bolt 3, a limiting hole 5 is formed in each half jacket 1, and the limiting hole 5 is matched with the limiting block 4 in size.

The limiting block 4 is provided with a mounting nut 6, the mounting nut 6 is in threaded connection with the jacking bolt 3, and the limiting block 4 is provided with a through hole for the jacking bolt 3 to pass through; the through hole is arranged coaxially with the mounting nut 6.

The end of the jacking bolt 3 is provided with a jacking block (not shown in the figure), and the size of the jacking block is smaller than the inner diameter of the bearing 9 with disassembly.

The pressing block is made of rubber, silica gel, TPU or sponge; when the end part of the jacking bolt 3 is jacked on the mechanical shaft 10, the jacking block made of soft materials can better protect the mechanical shaft 10.

The left side and the right side of the half jacket 1 are respectively provided with a connecting ring 11, and the two half jackets 1 are detachably connected through a fastening nut 7 and a fastening bolt 8 which are fastened on the connecting rings 11.

The limiting table 2 is a crescent plate, the crescent plate and the half jacket 1 are integrally formed or welded, and when the jacket is clamped on the bearing 9 to be detached, the end part of the bearing 9 is propped against the crescent plate.

The bearing disassembly tool comprises the following operation processes:

when the bearing 9 on the mechanical shaft 10 needs to be disassembled, the jacking blocks of the jacking bolts 3 are jacked on the mechanical shaft 10, the limiting holes 5 of the two half jackets 1 are respectively matched and clamped with the limiting blocks 4 on the jacking bolts 3, the crescent-shaped limiting platforms 2 are jacked on one end face of the jacket with the disassembling bearing 9 far away from the jacking mechanism, then the two half jackets 1 are gathered and aligned, the fastening bolts 8 are installed on the fastening nuts 7 of the two half jackets 1, the jacking bolts 3 are rotated, the rotation of the jacking bolts 3 can be realized by adopting external equipment such as a spanner or a motor, the rotation of the jacking bolts 3 and the limiting blocks 4 generate axial relative movement, at the moment, because the jacking bolts 3 are jacked on the mechanical shaft 10, the axial movement of the limiting blocks 4 cannot be realized, the limiting blocks 4 are clamped in the limiting holes 5, the jacket 4 drives the jacket to move, and the limiting platforms 2 of the jacket drive the jacket with the disassembling bearing 9 to move, and the relative movement of the jacket with the disassembling bearing 9 and the mechanical shaft 10 is realized until the disassembly of the bearing 9 is completed.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
