[0025] A bearing disassembly tool comprises a base 1, wherein the base 1 is provided with a bracket 2, the upper end of the bracket 2 is provided with a mounting arm 3, a disassembly screw 4 is installed on the mounting arm 3, a connecting plate 5 is rotatably installed on the lower end of the disassembly screw 4, a top block 6 is provided on the lower end of the connecting plate 5, a fixed bearing plate 7 is relatively installed in the middle part of the bracket 2, a bearing placement mechanism is detachably installed on the fixed bearing plate 7, a containing cup 8 is provided on the upper end surface of the base 1, and a buffer pad 9 is provided at the bottom of the containing cup 8.

[0026] Specifically, an L-shaped fixing groove 10 is provided at one end of the fixed supporting plate 7 away from the bracket, and a plurality of insertion rods 11 are provided on the horizontal portion of the L-shaped fixing groove 10. The bearing placement mechanism includes a placement plate 12, and a plurality of insertion holes 13 adapted to the insertion rods 11 are provided on the placement plate 12. A semicircular bearing placement groove 14 is provided at the end of the placement plate 12.

[0027] The holding cup 8 and the top block 6 are located on the same vertical line, and the cross-sectional dimension of the holding cup 8 is larger than the cross-sectional dimension of the top block 6 .

[0028] The placement plate 12 cooperates with the insertion rod 11 through the insertion hole 13 and is placed on the L-shaped fixing groove 10 to adapt to bearings of different sizes. The bearing can be clamped in the bearing placement groove 14. The operation is simple and convenient. Then the handle of the disassembly screw 4 is operated to move the top block 6 downward and push out the rotating shaft mounted on the bearing, thereby realizing the disassembly of the bearing. The lower end of the fallen rotating shaft falls vertically into the containing cup 8, and under the action of the buffer pad 9, it is prevented from being damaged by bumps.

[0029] Furthermore, a guide rail 15 is provided at the lower end of the fixed bearing plate 7 , an L-shaped bracket 16 is slidably mounted on the guide rail 15 , and a semicircular protective plate 17 is threadedly connected to the end of the horizontal portion of the L-shaped bracket 16 .

[0030] In the disassembly mode, the L-shaped bracket 16 can be slid to make the two semicircular protective plates 17 surround the shaft, so as to ensure that the lower end of the shaft falls vertically into the cup 8, and its upper part can be against the semicircular protective plates 17 to avoid damage caused by falling. Therefore, during the disassembly operation, only the disassembly screw rod needs to be operated, and there is no need to pay attention to the state of the shaft at any time, and it can also ensure that the shaft will not bump during the fall.

[0031] In order to further improve the installation stability of the placement plate, in this embodiment, the height of the placement plate 12 is consistent with the height of the vertical part of the L-shaped fixing groove 10, the height of the insertion rod 11 is lower than the height of the placement plate 12, and an anti-slip baffle 18 adapted to the placement plate 12 is rotatably installed on the fixed supporting plate 7.

[0032] By providing the anti-slip baffle 18, after the placement plate 12 is placed and fixed, the anti-slip baffle 18 is rotated to be located above the placement plate 12, thereby preventing the placement plate 12 from slipping out.

[0033] An anti-slip seat 19 is provided at the lower end of the base 1 .

[0034] Furthermore, a lubricating oil groove 20 is formed in an annular shape on the connecting plate 5 , and a plurality of oil leakage holes 21 are formed at the bottom of the lubricating oil groove 20 , and the oil leakage holes 21 are inclined toward the top block 6 .

[0035] The lubricating oil groove 20 and the oil leakage hole 21 are provided, and lubricating oil can be added therein during the disassembly process, so that the lubricating oil slowly drips to the connection part between the bearing and the rotating shaft, thereby improving the disassembly efficiency.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
