A pull-out type disassembly device for inner bushing of a bearing

Abstract

The invention discloses a tightly-propping pulling type detaching device for a bearing neck bush. The tightly-propping pulling type detaching device is used for achieving zero-damage detaching work of the bearing neck bush in the narrow space of a machine body and comprises a tightly-propping sleeve, a guiding supporting sleeve, an annular supporting seat, a pressing plate, a rotation nut assembly and a pull rod. The tightly-propping sleeve is of a split type hinged structure and is assembled with the left end of the pull rod, and the right end of the pull rod is assembled with the rotation nut assembly. The pull rod is sequentially sleeved with the guiding supporting sleeve, the annular supporting seat and the pressing plate from left to right, and the annular supporting seat is assembled with a bearing hole of the machine body. The tightly-propping pulling type detaching device solves the problem that the structural space of the machine body is small and a general tool cannot get into the machine body, damage to the structure of the machine body and the bearing neck bush is avoided, especially, the tightly-propping sleeve is of the hinged split structural design, the bearing neck bush can be accurately and tightly propped and positioned, and the detaching work efficiency of the bearing neck bush is improved.

Description

technical field [0001] The invention relates to a dismantling device for a bearing inner bush, in particular to a tensioning and pulling type dismantling device for a bearing inner bush, which belongs to the technical field of hand tools. Background technique [0002] As we all know, the assembly accuracy requirements of aircraft parts are very strict. Therefore, during aircraft maintenance operations, the disassembly and assembly of parts is one of the key links that affect the quality of work. as attached figure 1 As shown, in the maintenance process of a certain type of aircraft, the bearing inner bush 9 will remain on the airframe bearing seat 8 after the wing is disassembled, and the airframe bearing seat 8 is in the narrow space of the airframe structure, and can only pass through a diameter Ф120 The body bearing hole 10 of the body will remove the tool deep into the position of the body bearing seat 8, so it is very difficult to disassemble the bearing inner bushing ...

AI Technical Summary

Problems solved by technology

as attached figure 1 As shown, in the maintenance process of a certain type of aircraft, the bearing inner bush 9 will remain on the airframe bearing seat 8 after the wing is disassembled, and the airframe bearing seat 8 is located in the narrow space of the airframe structure, and can only pass through a diameter Ф120 The body bearing hole 10 of the body will remove the tool deep into the position of the body bearing seat 8, so it is very difficult to disassemble the bearing inner bushing 9 with existing general tools, which will not only cause damage to the body structure and bearing inner bushing 9, but also Work efficiency is also very low
