Bearing removal tool

This creation is about a bearing removal tool, especially a bearing removal tool that is small and easy to carry.

Most of the known bearing removal tools can only be used to remove a single size bearing from a bearing housing. If you need to disassemble other sizes of bearings, you must replace them with other sizes of bearing removal tools or replace some components, resulting in users. Carrying the burden.

Another conventional bearing removal tool comprises a two-pillar, a support beam, a screw, a nut and a mandrel. In use, the two support columns are first supported on the bearing seat around the bearing, and then the The support beam is connected between the support columns, and the support beam must be used to adjust the distance between the support columns to correspond to the diameter of the bearing, so that the distance between the support columns is greater than the diameter of the bearing, Inserting the mandrel into the bearing hole of the bearing, and inserting the screw into the mandrel, so that the mandrel is stretched and pressed into the bearing hole, and then rotating the nut disposed on the screw, so that the nut The nut continues to abut against the support beam, and the screw is reversely rotated away from the bearing seat. At this time, the bearing can be disengaged from the bearing seat by the screw to complete the disassembly of the bearing. However, due to the numerous components of the bearing dismounting tool, it is time consuming and laborious to erect the bearing dismounting tool, and the overall volume of the bearing dismounting tool is still large and inconvenient to carry.

Therefore, how to create a bearing disassembly tool and improve the overall volume of the conventional bearing disassembly tool is large and inconvenient to carry, which will be actively exposed by the creative office.

In order to solve the above-mentioned shortcomings of the prior art, the present invention provides a bearing dismounting tool, which is suitable for disassembling bearings of various sizes and having the advantages of small size and convenient carrying.

To achieve the above and other objects, the present invention provides a bearing removal tool including a pushing member, a nut and a hollow shaft, the pushing member including a threaded portion and one of the threaded portions The shank is movably disposed on the threaded portion, and the hollow shaft is sleeved on the urging portion, wherein the bearing detaching tool further comprises a first sleeve and a second sleeve. The first sleeve includes a through hole and a first joint portion, and the first joint portion is disposed on an outer wall surface of one end of the first sleeve, and the pusher member is movably disposed in the through hole. And the second sleeve includes a second joint portion, and the second joint portion is disposed on an inner wall surface of one end of the second sleeve and joined to the first joint portion.

The bearing removal tool as described above further includes a third sleeve, the third sleeve includes a fourth joint portion, the fourth joint portion is disposed on an inner wall surface of the third sleeve, and the second sleeve The barrel includes a third joint portion disposed on an outer wall surface of the other end of the second sleeve, the fourth joint portion being joined to the third joint portion.

In the bearing removal tool as described above, the first sleeve is provided with one end of the first joint portion including at least one first notch.

In the bearing removal tool as described above, the second sleeve includes at least one second notch away from one end of the second joint.

In the bearing detaching tool as described above, the free end of the third sleeve includes at least a third notch.
