Abstract
The utility model is related to a kind of borescope hole stopper structure；It includes bolt head, blocked shot, it is characterised in that the rod end oscillating bearing between bolt head and blocked shot.Spherical plain bearing rod end is bulb spherical plain bearing rod end.Rod end can be around bulb beat certain angle；It is made of self-lubricating material, belongs to self-lubricating ball head spherical plain bearing rod end.The utility model solves cumulative limit and causes outer culvert casing and compressor stator casing mounting hole concentricity tolerance caused borescope hole plug installation difficulty bigger than normal；Solve the problems, such as that operating temperature difference causes greatly outer culvert casing and the inconsistent caused borescope hole plug stress deformation of compressor stator casing mounting hole axial displacement.The utility model is simple in construction, assembling is reliable, with preferable technology application value.
Description
Technical field
The utility model belongs to engine compressor field of components, is related to a kind of the new stifled of compressor part borescope hole
Header structure.
Background technology
As shown in Figure 1, intrinsic borescope plug is one to intrinsic compressor part borescope hole stopper structure
Threaded and bolt head straight-bar structure.Due to casing axial dimension tolerance stack and circumferential angle tolerance, outer culvert casing and pressure
The axiality form and position tolerance of the borescope mounting hole of mechanism of qi rectification casing is bigger than normal, and the assembling of borescope plug will be caused difficult.Because of work
Making temperature difference causes greatly outer culvert casing and compressor stator casing mounting hole axial displacement inconsistent, causes borescope hole to block up
Head stress deformation, there is the risk for cracking failure in the case of long-term work.
The content of the invention
The purpose of this utility model：
The purpose of this utility model is：A kind of stopper structure in borescope hole is provided, solved the above problems.
The technical solution of the utility model：
As shown in Figure 1, intrinsic compressor part borescope hole plug is threaded and bolt head a straight-bar knot
Structure；The characteristics of the utility model can deflect certain angle using the rod end of bulb spherical plain bearing rod end (2) around bulb, by bulb
Spherical plain bearing rod end (2) is applied in the stopper structure of compressor borescope hole.The utility model solves what cumulative limit was caused
Outer culvert casing and compressor stator casing mounting hole axiality problem；Solve operating temperature difference it is big caused by it is outer contain casing with
The problem of compressor stator casing mounting hole axial displacement is inconsistent.
A kind of stopper structure in borescope hole, it includes bolt head, blocked shot, it is characterised in that bolt head and blocked shot it
Between rod end oscillating bearing.
Spherical plain bearing rod end is bulb spherical plain bearing rod end.
The beneficial effects of the utility model：
The utility model has the characteristics that and effect：
(1) the characteristics of the utility model can deflect certain angle using bulb spherical plain bearing rod end, by self-lubricating bulb
Spherical plain bearing rod end is used in compressor borescope stopper structure.
(2) the utility model solves outer culvert casing and the compressor stator casing mounting hole axiality that cumulative limit is caused
Problem.
(3) the utility model solves the big caused outer culvert casing of operating temperature difference and compressor stator casing mounting hole
The problem of axial displacement is inconsistent.
Brief description of the drawings
Fig. 1 is the utility model structure and former design structure contrast schematic diagram；
Fig. 2 is the rod end of bulb spherical plain bearing rod end around bulb deflection angle schematic diagram；
In figure, 1- bolt heads, 2- bulbs spherical plain bearing rod end, 3- blocked shots.
Embodiment
Below by embodiment, the utility model is described in further detail：
As shown in figure 1, containing the screw thread that casing uses M24 × 1.5 with bolt head (1) mate with threaded holes outside, its path is Φ
22.376.Fig. 2 be the rod end of bulb spherical plain bearing rod end (2) around bulb deflection angle schematic diagram, the deflection angle β of rod end is general
At 10~15 ° or so, it is fully able to meet requirement of the structure of the present invention to deflection angle.The ball of bulb spherical plain bearing rod end (2)
Head shell maximum gauge is S Φ 20, and the part can have no problem through the screwed hole of outer culvert casing M24 × 1.5, assembling.
Claims (3)
1. a kind of stopper structure in borescope hole, it includes bolt head, blocked shot, it is characterised in that between bolt head and blocked shot
Rod end oscillating bearing.
2. the stopper structure in borescope hole according to claim 1, it is characterised in that spherical plain bearing rod end is that bulb rod end is closed
Bearings.
