Abstract
The utility model provides a spline hollow shaft subassembly includes axis body, external tooth cover, the one end of axis body is equipped with the spline, external tooth cover is the annular, and the inner ring is equipped with the spline groove, the spline cooperatees with the spline groove, the axis body is hugged closely the spline lower extreme and is equipped with an annular groove, the spline number is 5~36 on the axis body, be equipped with positioning groove on the axis body, be equipped with the sealing washer in the positioning groove. The utility model discloses an adopt the split type hollow shaft of splined connection, reduction in production cost, simple structure, the result of use is obvious.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, particularly relates to a kind of hollow spline assembly for gear-box.
Background technique
Uni-drive gear box belongs to the vitals in machinery, and it assume responsibility for the transmission of power of machinery, and the output shaft form of gear-box is mainly divided into solid shaft to export according to the difference of its latter linked coupling and hollow shaft exports two kinds.When hollow shaft exports, due to the particularity of its structure, the cooperation of internal tooth casing is needed in assembly process, current hollow shaft mostly adopts gear to connect or Flange joint, high for point body component precision requirement, cost of production is improved, and consumptive material increases, therefore invent a kind of cost of production low, the hollow shaft assembly that consumptive material is few seems particularly important.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of new hollow spline assembly.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hollow spline assembly, comprises axis body, external tooth cover, and one end of described axis body is provided with spline, and described external tooth cover is annular, and be inside equipped with spline, described spline matches with spline.
Split type hollow axle of the present utility model and external tooth cover, by spline joint, compare gear connecting way, reduce the precision of equipment, reduce cost of production, reduce consumptive material.
Preferably, described axis body upper spline number is 5 ~ 36.
Preferably, described axis body upper spline number is 16.
Preferably, described axis body is provided with positioning groove, is provided with seal ring in described positioning groove.This preferred version is positioned at gear-box due to hollow shaft, arranges seal ring and is conducive to seal case, reduces oil leakage phenomenon.
Preferably, described axis body is close to spline lower end and is provided with an annular groove.This optimal way is close to spline lower end and is provided with annular groove, more carefully and neatly done when can make component processing, real external tooth cover spline and hollow shaft one end spline engagement more abundant, ensure operation stability, and effectively can prevent the play between hollow shaft and external tooth cover, decrease the friction to seal ring, improve the working life of seal ring.
The beneficial effects of the utility model are: Split type hollow axle, by spline joint, is compared gear connecting way, reduced cost of production, reduce consumptive material.Be close to the annular groove of spline lower end, more carefully and neatly done when can make component processing, real external tooth cover spline and hollow shaft one end spline engagement more abundant, ensure operation stability, and effectively can prevent the play between hollow shaft and external tooth cover, decrease the friction to seal ring, improve the working life of seal ring.。
Accompanying drawing explanation
Fig. 1 is the overall structure schematic top plan view of hollow spline assembly of the present utility model;
Fig. 2 be the utility model central axis face structural representation;
Fig. 3 is the plan view of Fig. 2.
In figure: 1-axis body, 2-external tooth cover, 3-spline, 4-spline, 5-annular groove, 6-positioning groove, 7-seal ring.
Embodiment
Following introduction according to Fig. 1 illustrates an embodiment of the present utility model.
A kind of hollow spline assembly, comprise axis body 1, external tooth cover 2, one end of described axis body 1 is provided with spline 3, described external tooth cover 2 is annular, and be inside equipped with spline 4, described spline 3 matches with spline 4, described axis body 1 is close to spline 3 lower end and is provided with an annular groove 5, described axis body 1 upper spline number is 16, and described axis body 1 is provided with positioning groove 6, is provided with seal ring 7 in described positioning groove 6.
Axis body 1 and external tooth cover 2 are engaged each other by spline, and form one, on axis body 1, seal ring 7 is for keeping airtight in gear-box, prevents lubricating oil leakage.Hollow shaft and miscellaneous part combine and form complete gear wheel case.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
Claims (3)
1. a hollow spline assembly, comprise axis body, external tooth cover, it is characterized in that: one end of described axis body is provided with spline, described external tooth cover is annular, inside be equipped with spline, described spline matches with axis body spline, and described axis body is provided with positioning groove, be provided with seal ring in described positioning groove, described axis body is close to spline lower end and is provided with an annular groove.
