Embodiment Construction

[0026] The present invention will be further described in conjunction with the following examples.

[0027] A kind of PR wheel bearing dismantling jig described in the present invention, such as figure 1 , figure 2 As shown, it includes a bearing card 100 for clamping the PR wheel bearing 410, an extractor sleeve 200 for accommodating the PR wheel shaft center 400, and an ejector device 300. One end of the bearing card 100 and the extractor sleeve 200 is clamped, and the A portion of the device 300 is located within the extractor sleeve 200 and rests against the end of the PR wheel axle 400 away from the PR wheel bearing 410 . Bearing card 100, under the action of extractor sleeve 200 and ejector device 300, thrust acts on the outer ring and inner ring of PR wheel bearing 410 at the same time, and it is not easy to damage PR wheel bearing 410 during disassembly; adopt bearing card 100 and extractor sleeve 200 split structure, different types of PR wheel bearings 410 can be...

Abstract

The invention belongs to the technical field of maintenance of mechanical equipment and particularly relates to a PR wheel bearing dismounting clamp. The PR wheel bearing dismounting clamp comprises a bearing clip used for clamping a PR wheel bearing, an extractor sleeve used for accommodating a PR wheel axis, and a lift-out device; the bearing clip is connected with one end of the extractor sleeve in a clamping manner; and a part of the lift-out device is positioned in the extractor sleeve and is propped against one end of the PR wheel axis, which is away from the PR wheel bearing. According to the PR wheel bearing dismounting clamp provided by the invention, the bearing clip is under the action of a pushing force of the extractor sleeve and the lift-out device, and the pushing force is applied on the outer ring and the inner ring of the bearing at the same time, so that the bearing is not damaged easily when being dismounted; and the bearing clip and the extractor sleeve are arranged in a split manner, and different models of bearings can be used with corresponding models of bearing clips and with the same extractor sleeve, so that the structure is simple, the dismounting speed is high, the use is convenient, the dismounting effect is good, and the PR wheel bearing dismounting clamp is particularly suitable for dismounting bearings on PR wheels.

Description

technical field [0001] The invention belongs to the technical field of fixtures for maintenance of mechanical equipment, in particular to a fixture for removing PR wheel bearings. Background technique [0002] Generally speaking, the bearing is fixed on the shaft by interference fit, but it is often necessary to disassemble the bearing from the shaft during repair and maintenance. The removal method includes tapping the metal rod with a hammer to slowly knock the bearing out , but this method is very inefficient, inconvenient to disassemble, and will damage the bearing during knocking. [0003] In order to improve this situation, various devices for dismounting bearings have appeared. The more common one is the triangle puller. The triangle puller uses three claws to buckle one side of the bearing, and then pulls the triangle puller so that Drive the movement of the bearing, but in the process of using the triangle puller, the triangle puller mainly acts on the outer ring o...
