Abstract
A kind of splines shell of the utility model, relates to auto parts machinery and prepares field, including body, the axle center of described body is provided with central shaft hole；Described body is divided into installation end and abutting end；The outer surface of described installation end is provided with reticulate pattern；The outer surface of described abutting end is provided with multiple projection；Described projection is uniformly distributed along rotary surface；It is provided with positive stop lug boss between described installation end and abutting end；Described installation end is additionally provided with the turning slot caving inward.This splines shell is it can be avoided that the connection that coupling part occurs during docking deforms.And this splines shell prepares precision height, installs and convenient disassembly, the tight ness rating of cooperation is good, reliability and durability.
Description
Technical field
The utility model relates to auto parts machinery and prepares field, particularly relates to a kind of splines shell.
Background technology
In the attachment structure of automobile, generally shaft element realizes connection by being mutually butted, in order to improve the security connecting between structure, it is to avoid its docking is insecure produces fracture, generally uses the splines shell of tubulose to carry out closed and butted in two or more junctions.Structure is interconnective be inserted partially into splines shell after, in addition it is also necessary to use pressure apparatus be attached fixing on splines shell, so result in structure connect and dismounting Operating Complexity.Further, owing to the deformation of splines shell is very easy to again cause coupling part that the phenomenon loosening and coming off occurs.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of splines shell, and it is reasonable in design, simple in construction, solves spline connection structure inconvenience and holds caducous problem.
For solving above-mentioned technical problem, the technical scheme that the utility model uses is to provide a kind of splines shell, including body, the axle center of described body is provided with central shaft hole；Described body is divided into installation end and abutting end；The outer surface of described installation end is provided with reticulate pattern；The outer surface of described abutting end is provided with multiple projection；Described projection is uniformly distributed along rotary surface；It is provided with positive stop lug boss between described installation end and abutting end；Described installation end is additionally provided with the turning slot caving inward.
Preferably, described projection is provided with 3, and 3 projections are distributed on the rotary surface of described abutting end.
Preferably, described three projections are respectively first protruding, the second protruding and the 3rd projection；Central angle between first projection and the second projection is 145 °；Central angle between second projection and the 3rd projection is 75 °.
The beneficial effects of the utility model are: provide a kind of splines shell, it can be avoided that the connection deformation that coupling part occurs during docking.And this splines shell prepares precision height, installs and convenient disassembly, the tight ness rating of cooperation is good, reliability and durability.
Brief description
Fig. 1 is the structural representation of a kind of splines shell of the utility model；
Fig. 2 is the structure sectional view of splines shell；
In accompanying drawing, the mark of each parts is as follows: the 1st, installation end；2nd, abutting end；3rd, protruding；4th, positive stop lug boss；5th, turning slot.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantages and features of the present utility model can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made and apparent clearly defines.
Referring to attached Fig. 1 and 2, the utility model embodiment includes:
A kind of splines shell, including body, the axle center of described body is provided with central shaft hole；Described body is divided into installation end 1 and abutting end 2, and the external diameter of installation end 1 is 7.2mm, and the external diameter of abutting end 2 is 7.0mm；The outer surface of described installation end 1 is provided with reticulate pattern, reticulate pattern: m0.20 p=0.8；The outer surface of described abutting end 2 is provided with multiple protruding 3；Described protruding 3 are uniformly distributed along rotary surface；Being provided with positive stop lug boss 4 between described installation end 1 and abutting end 2, the thickness of positive stop lug boss is 1.9mm；Described installation end is additionally provided with the turning slot 5 caving inward.Projection is provided with 3, and 3 projections are distributed on the rotary surface of described abutting end.Described three projections are respectively first protruding, the second protruding and the 3rd projection, and the width of the first projection is 1.5mm, and the second protruding width with the 3rd projection is 1.0mm；Central angle between first projection and the second projection is 145 °；Central angle between second projection and the 3rd projection is 75 °.This splines shell is it can be avoided that the connection that coupling part occurs during docking deforms.And this splines shell prepares precision height, installs and convenient disassembly, the tight ness rating of cooperation is good, reliability and durability.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing the utility model description to be made or equivalence flow process conversion; or it is directly or indirectly used in other related technical fields, all in like manner include in scope of patent protection of the present utility model.
