Along with the development of rubber oil sea technology, it is increasingly mature that the installation method of rubber oil sea is studied by people, rubber oil
The dismounting of envelope is the most out in the cold, and main engine plants typically use barbarous dismounting, the rubber oil sea gross distortion after dismounting.If there is letting out
The situation of leakage effect, personnel after sale are corrupted to product sealing surface when dismantling, have no point for the manufacturer of rubber oil sea
The value of analysis, it is impossible to distinguish the reason of inefficacy, it is impossible to the problem fundamentally solving to lose efficacy.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that can also be right after a kind of dismounting
The rubber oil sea of the band removal hole that work surface is analyzed.
The purpose of this utility model can be realized by following technical proposal: the rubber oil sea of a kind of band removal hole, including
Mounting shell, installation axle, rubber bodies, support frame and spring, support frame is positioned at rubber bodies, with mounting shell mistake outside rubber bodies
Contact of being full of forms external seal face, and inner side has set ring packing lip on the mounting shaft, and the seal lip back side is provided with spring groove,
Spring housing on spring groove, spring compression seal lip, make seal lip form inner sealing surface with installing axle Interference contact, it is special
Levy and be: inner sealing surface and external seal face form the work surface of rubber bodies, and the non-working surface bottom rubber bodies has for rubber
The integral part of facing groove of body, the support frame that the facing groove back side is corresponding has removal hole.
Owing to having facing groove on the non-working surface of rubber bodies, and have on support frame corresponding to the facing groove back side
There is removal hole, penetrate rubber bodies hence with extracting tool by removal hole, product is taken out of, the work of product will not be destroyed
Face, it is ensured that the integrity of product, can be analyzed work surface afterwards, to determine leakage reason.
In the rubber oil sea of above-mentioned a kind of band removal hole, bottom described rubber bodies, it is provided with some facing groove,
There are on support bone frame the some removal holes being corresponding in turn to some facing groove, and some facing groove and removal hole are around installation
Axle is distributed.
Multiple instrument is the most conveniently utilized together to coordinate dismounting.
In the rubber oil sea of above-mentioned a kind of band removal hole, the described facing groove back side is embedded in removal hole, and end
Face groove bottom land and removal hole correspondence position have depression.
Therefore facilitate and determine removal hole position by depression.
In the rubber oil sea of above-mentioned a kind of band removal hole, described removal hole flare cavernous structure, and laminating
One end hole wall at the facing groove back side is less than other end hole wall.
Therefore instrument is facilitated to penetrate removal hole.
Compared with prior art, this utility model has the advantage that
Owing to having facing groove on the non-working surface of rubber bodies, and have on support frame corresponding to the facing groove back side
There is removal hole, penetrate rubber bodies hence with extracting tool by removal hole, product is taken out of, the work of product will not be destroyed
Face, it is ensured that the integrity of product, can be analyzed work surface afterwards, to determine leakage reason.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As it is shown in figure 1, the rubber oil sea of this utility model a kind of band removal hole, including mounting shell 1, axle 11, rubber are installed
Body 2, support frame 3 and spring 41, support frame 3 is positioned at rubber bodies 2, is formed with mounting shell 1 Interference contact outside rubber bodies 2
External seal face 21, inner side has the ring packing lip 22 being enclosed within installation axle 11, and seal lip 22 back side is provided with spring groove 4,
Spring 41 is enclosed within spring groove 4, and spring 41 compresses seal lip 22, in making seal lip 22 be formed with installation axle 11 Interference contact
Sealing surface 23, inner sealing surface 23 and external seal face 21 form the work surface of rubber bodies 2, and the non-working surface bottom rubber bodies 2 has
The promising integral part of facing groove of rubber bodies 2 24, the support frame 3 that facing groove 24 back side is corresponding has removal hole 31.
Further, bottom rubber bodies 2, it is provided with some facing groove 24, support frame 3 has and some facing groove
The 24 some removal holes 31 being corresponding in turn to, and some facing groove 24 and removal hole 31 be distributed around installing axle 11.Facing groove
