Embodiment 1

[0046] A bearing 10 quick removal tool, the removal tool includes:

[0047] A pneumatic disc 40, the upper end surface of the pneumatic disc 40 has a rectangular groove;

[0048] Specifically, the pneumatic disc 40 is circular and preferably made of metal. When the bearing 10 is disassembled with a dismounting tool, the centers of the pneumatic disc 40 and the shaft 90 are collinear, and the upper end surface of the pneumatic disc 40 is close to the shaft 90 and The side opposite to the end face of the shaft 90.

[0049] A pneumatic block 30, the pneumatic block 30 is arranged in the rectangular groove, and the upper surface of the pneumatic block 30 has a wavy surface;

[0050] Specifically, the pneumatic block 30 is long and preferably made of metal; and the hardness of the pneumatic block 30 is smaller than that of the pneumatic disc 40, so that the pneumatic block 30 can bear the pneumatic block 30 and the pneumatic disc 40 during long-term use. The loss of friction betw...

Embodiment 2

[0076] On the basis of Embodiment 1, do further optimization, specifically:

[0077] The wavy surface of the pneumatic block 30 is composed of triangular tooth grooves. The lower surface of the pneumatic clamp 20 is provided with a triangular tooth groove matching the pneumatic block 30 .

[0078] Specifically, the purpose of setting the wavy surface is to achieve orderly adjustment between the pneumatic block 30 and the pneumatic clamp 20, and also to prevent the relative rotation and slippage between the pneumatic clamp 20 and the pneumatic block 30; so the setting of the tooth groove It can be formed in various forms, which can be set as trapezoidal alveolar or square alveolar; among them, setting triangular alveolar is the most choice. First, under the same area, when the triangular alveolar is mated and connected, the fitting relationship between the surface and the surface At most, the effect of preventing rotation and slippage is the best; the second is the matching co...

Embodiment 3

[0087] On the basis of embodiment one or two, do further optimization, specifically

[0088]The removal tool includes: a cover 60 , one end of the cover 60 is connected to the lower end surface of the base 100 , and a side surface of the cover 60 is arranged on the outer wall of the stressed column 70 .

[0089] Specifically, the cover 60 is set on the force-bearing column 70 and connected to the base 100. One is to cover the pressure sleeve 50 in the cover 60 to prevent uneven force or excessive force, resulting in ejection and fragmentation. The second is to unify the force transmission direction of the base 100 and the stressed column 70, so as to avoid deviations in the applied force direction of the stressed column 70 to the shaft 90 and the applied force direction of the pneumatic clamp 20 to the bearing 10. The first is to cause the disassembly of the bearing 10. The second is that the bearing 10 and the shaft 90 are easily damaged during the disassembly process; the th...

Abstract

An embodiment of the invention provides a quick detaching tool for a bearing and belongs to the technical field of detaching tools. The detaching tool comprises a pneumatic disk, a pneumatic block, apneumatic clamp, a base, a pressure sleeve, a stressed column, a hydraulic disk and a hydraulic mechanism; a rectangular groove is formed in the upper end surface of the pneumatic disk; the pneumaticblock is arranged in the rectangular groove; a wavy surface is arranged on the upper surface of the pneumatic block; the lower surface of the pneumatic clamp is connected with the wavy surface of thepneumatic block; the bearing is clamped in the bent position of the pneumatic clamp; the pressure sleeve is arranged at the top end of the bearing; the outer surface of the pressure sleeve is connected with the base; one end of the stressed column is connected with the pressure sleeve; a round groove is formed in the other end of the stressed column; the hydraulic disk is connected with the roundgroove of the stressed column; the hydraulic mechanism is connected with the hydraulic disk. By the aid of the detaching tool, the problem that the bearing or other parts are prone to damage by commondetaching manners and detaching tools is solved.

Description

technical field [0001] The invention relates to the technical field of disassembly tools, in particular to a quick disassembly tool for bearings. Background technique [0002] Bearings are an indispensable part of mechanical transmission. During the installation process, the precision between the shafts that are required to be matched with them is high. Generally, it is an interference fit, so as not to cause movement during the working process, which will affect the reliability of the operation, especially In the field of aviation, higher precision is required for its installation, such as the bearing on the tail drive shaft of a helicopter. In order to meet the requirements of use, during installation, the method of heating the inner ring of the bearing is generally used to enlarge the inner diameter, and then the bearing is assembled to the shaft by a press. [0003] However, during disassembly, since the inner ring of the bearing cannot be heated alone, and due to the p...
