Description

Technical Field

[0001] This utility model relates to the field of turbine bushing technology, specifically a wear-resistant and anti-detachment turbine housing bushing structure. Background Technology

[0002] A turbine is a fan in a car or airplane engine that uses exhaust gases to blow fuel vapor into the engine, thereby improving engine performance. A turbine is a rotating power machine that converts the energy of a flowing working fluid into mechanical work. It is one of the main components of aircraft engines, gas turbines, and steam turbines. To increase the wear resistance of the turbine housing's inner wall, existing technology typically incorporates wear-resistant bushings on the inner wall of the turbine housing.

[0003] A turbine housing bushing with easy press-fitting is described in the prior art (application number 202221967551.1). It includes a bushing body with an upper limit seat installed at one end, the width of which is greater than the thickness of the bushing body. An inclined end face is provided on the outer side of the lower end of the bushing body, and an outer reinforcing rib is installed on the outer side of the bushing body. The upper limit seat at one end of the bushing body increases the press-fitting contact surface, and the inclined end face facilitates rapid press-fitting of the bushing body into the turbine housing. The outer reinforcing rib, inserted into the limiting groove of the turbine housing, improves the installation and positioning stability of the bushing body, resulting in high structural strength and long service life. However, the stability of the bushing installation and fixing is relatively poor, and disassembly and assembly are inconvenient. Summary of the Invention

[0004] The purpose of this utility model is to provide a wear-resistant and anti-detachment turbine housing bushing structure to solve the problems of general stability of bushing installation and fixation and inconvenience of disassembly and assembly in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant and anti-detachment turbine housing bushing structure, comprising a turbine housing and a bushing body, wherein the inner wall of the turbine housing is provided with a first snap-fit ​​groove, the bushing body is configured as a plurality of bushing blocks, and the outer sides of the plurality of bushing blocks are snapped and fixed to the first snap-fit ​​groove by a first snap-fit ​​seat, the outer side of the center seat inside the turbine housing is provided with a second snap-fit ​​groove, and the inner side of the bushing block is also snapped and engaged with the second snap-fit ​​groove by a second snap-fit ​​seat, and the turbine housing and the first snap-fit ​​seat are further limited by an insertion seat and a limiting groove.

[0006] Furthermore, the bushing block is configured as an arc-shaped block, and the inner wall of the bushing block is provided with a wear-resistant layer.

[0007] Furthermore, the wear-resistant layer is made of polyurethane rubber and has a thickness of 0.5-1.5 mm.

[0008] Furthermore, both the first and second locking seats are welded perpendicularly to the bushing block, and the included angle between two adjacent locking seats is ninety degrees.

[0009] Furthermore, the connector is configured as an L-shaped support, and one end of the connector slides through the limiting hole in the side wall of the turbine housing, and one end of the connector is provided with a connector block.

[0010] Furthermore, one end of the connector is also threadedly connected to a locking bolt through a threaded hole, and the locking bolt is vertically rotated and positioned outside the turbine housing via a bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model sets the bushing body into multiple bushing blocks, and the multiple bushing blocks are fixed to the turbine housing by a first snap-fit ​​seat, a second snap-fit ​​seat, a first snap-fit ​​groove and a second snap-fit ​​groove. This makes it easy to install the bushing body in the turbine housing, and the installation and fixing stability is high. It is convenient and quick to disassemble and assemble. Moreover, if there is serious local damage, only a single bushing block needs to be replaced, and the whole system does not need to be replaced, thus improving the utilization rate of resources.

[0013] Furthermore, this invention increases the wear resistance of the inner wall of the turbine housing by providing a bushing body inside the turbine housing. At the same time, the inner wall of the bushing block is also provided with a wear-resistant layer, which improves the wear resistance of the inner wall of the bushing block, thereby further improving the wear resistance of the inner wall of the turbine housing.

[0014] Furthermore, the turbine housing and the first snap-fit ​​seat are further limited by a plug-in seat and a limiting groove. One end of the plug-in seat is also threadedly connected to a locking bolt through a threaded hole. The locking bolt is vertically rotated outside the turbine housing by a bearing, so that the plug-in seat can be moved and adjusted by rotating the locking bolt. When the plug-in block at one end of the plug-in seat is inserted into the limiting groove, it can limit the first snap-fit ​​seat that is snapped into the first snap-fit ​​groove, thereby improving the stability of the bushing block installed in the turbine housing. At the same time, rotating the locking bolt in the opposite direction causes the plug-in block to be pulled out of the limiting groove, which facilitates the disassembly of the bushing block.

This hole is used to guide the movement of the plug-in seat 10 during adjustment, which helps to improve the stability of the plug-in seat 10 when it is plugged in and fixed. A plug-in block 6 is provided at one end of the plug-in seat 10, and a locking bolt 11 is threadedly connected to one end of the plug-in seat 10 through a threaded hole 13. The locking bolt 11 is vertically rotated outside the turbine housing 1 through a bearing 12, which facilitates the adjustment of the movement of the plug-in seat 10 by rotating the locking bolt 11.
