In order to make the purpose, technical solution and advantages of the embodiments more apparent, the present invention is further described in detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

In the embodiment, as shown in fig. 1, fig. 2 and fig. 3, a bearing dismounting tool comprises a fixing ring 1 and a supporting plate 2, wherein the fixing ring 1 and the supporting plate 2 are parallel to each other and are arranged in a front-back manner; the fixing ring 1 is circular and mainly used for fixing a bearing to be disassembled and being convenient to take out. The support plate 2 is a circular plate body, and the main function of the support plate is to provide a supporting force to disassemble the bearing.

The front surface of the fixing ring 1 is provided with an annular clamping groove 3, the diameter of the annular clamping groove 3 is consistent with the diameter of an outer ring of a bearing to be disassembled, the fixing ring 1 is composed of a first semi-ring 4 and a second semi-ring 5, and the first semi-ring 4 and the second semi-ring 5 both comprise a rotating end and a separating end; the front of solid fixed ring 1 is provided with annular ring groove 3 of circle, and ring groove 3 is unanimous with the outer lane diameter of the bearing that needs to be dismantled, when the bearing was dismantled to needs, goes into ring groove 3 with the outer lane card of bearing in, then screws up solid fixed ring 1 to the bearing has been in the same place with solid fixed ring 1 zonulae occludens. The fixing ring 1 is composed of a first half ring 4 and a second half ring 5, when the first half ring 4 and the second half ring 5 are separated by taking a rotating end as a center, the first half ring 4 and the second half ring 5 can be buckled on the bearing, then the separated ends of the first half ring 4 and the second half ring 5 are fixed together, and the fixing ring 1 finishes the fixing of the outer ring of the bearing.

The rotating ends of the first half ring 4 and the second half ring 5 are fixed together by a rotating shaft 6, the first half ring 4 and the second half ring 5 can rotate around the rotating shaft 6 as a center, the separated ends of the first half ring 4 and the second half ring 5 are both provided with a first threaded hole 7, and a first screw 8 can be arranged in the first threaded hole 7 to fix the first half ring 4 and the second half ring 5 together; the rotating ends of the first half ring 4 and the second half ring 5 are connected through a rotating shaft 6 and can rotate around the rotating shaft in a small range. The first threaded holes 7 are formed at the separated ends of the first half ring 4 and the second half ring 5, and when the first half ring 4 and the second half ring 5 need to be fixed, the first threaded holes 7 on the first half ring 4 and the second half ring 5 are overlapped, so that the first threaded rods 8 can be screwed into the first threaded holes 7 to fix the first half ring 4 and the second half ring 5 together.

The back of the fixing ring 1 is provided with the supporting plate 2, the supporting plate 2 is provided with a second threaded hole 9, a second screw 10 is installed in the second threaded hole 9, and the second screw 10 faces to the inner ring of the fixing ring 1; the back of the fixing ring 1 is provided with a supporting plate 2, the center of the supporting plate 2 is provided with a second threaded hole 9, and a second screw rod 10 is installed in the second threaded hole 9. When the second screw 10 is rotated, the second screw 10 moves toward the fixing ring 1.

The backup pad 2 with it connects to be provided with two at least third screw rods 11 between the solid fixed ring 1, third screw rod 11 can with gu fixed ring 1 with the relative position of backup pad 2 is fixed. Two third screws 11 are arranged between the support plate 2 and the fixing ring 1, and the third screws 11 provide supporting force to fix the relative positions of the fixing ring 1 and the support plate 2.

The second threaded hole 9 is formed in the middle of the supporting plate 2, and the second screw 10 is opposite to the center of the inner ring of the fixing ring 1. The second screw hole 9 is installed at the center of the support plate 2, and thus the second screw 10 is also installed at the center of the support plate 2. When the screw is installed in the middle of the support plate 2, the force applied to the support plate 2 is more uniform. The second screw 10 faces the centre of the inner ring of the fixed ring 1, which in use of the tool faces the inner shaft of the bearing, thus making the force exerted by the second screw 10 on the inner shaft of the bearing more uniform.

The third screw 11 is connected to the first half ring 4 of the fixed ring 1 from the supporting plate 2, and the third screw 11 is arranged symmetrically by taking the inner ring of the fixed ring 1 as the center. The third screw 11 is connected between the support plate 2 and the first half ring 4 of the fixing ring 1, so that the position of the support plate 2 and the fixing ring 1 is fixed. Meanwhile, when the second half ring 5 rotates around the rotating shaft 6 as a center, since the second half ring is not connected to the third screw 11, the rotation of the second half ring 5 is not affected. Two third screw rods 11 are symmetrically arranged, so that the force exerted by the second screw rods 10 on the fixing ring 1 and the supporting plate 2 is more uniform.

The fixing ring 1 is in a circular ring shape, the supporting plate 2 is a circular plate body, and the diameter of the outer ring of the fixing ring 1 is the same as that of the outer ring of the supporting plate 2. The fixing ring 1 is circular, the supporting plate 2 is circular, and the diameters of the fixing ring and the supporting plate are the same.

The fixing ring 1 and the supporting plate 2 are both made of steel. The fixing ring 1 and the supporting plate 2 need to bear certain supporting force, so that steel is selected, and the fixing ring is more durable.

The following is further detailed by the specific embodiments: when the bearing needs to be disassembled, the second screw rods 10 on the first half ring 4 and the second half ring 5 are removed, so that the first half ring 4 and the second half ring 5 are separated, the first half ring 4 and the second half ring 5 are buckled on the outer ring of the bearing, then the second screw rods 10 are installed, and then the bearing is fixedly connected together by the fixing ring 1.

The second screw 10 is then rotated and the second screw 10 extends in the bearing direction until it contacts the inner shaft on the bearing. Then, the second screw 10 is rotated continuously, so that the bearing is driven by the fixing ring 1 and the support plate 2 to move in the opposite direction of the movement of the second screw 10, and finally the bearing is detached from the inner shaft.

The above description is only an example of the present invention, and the common general knowledge of the known specific structures and characteristics of the embodiments is not described herein. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
