Abstract
The utility model discloses a kind of spline housing, it comprises circular axis body, it is characterized in that: the inner ring of described axis body is provided with the internal spline of several projection, described internal spline is an isosceles trapezoid shape, and the dual-side of described internal spline is provided with the many chutes caved in.Spline housing of the present utility model is equidistantly provided with the internal spline of several projection for increasing friction at the inner ring of axis body, increases driving force; At least arrange six internal splines then because the number of teeth is more, total area of contact is comparatively large, thus can bear larger load; And six internal splines facilitate centering, centering is good, this at a high speed and precision machinery very important.It is simple that the utility model has structure, long service life, low cost and other advantages.
Description
Technical field
The utility model relates to a kind of auxiliary component, especially a kind of spline housing.
Background technique
Splined is made up of internal spline and external splines.Inside and outside spline is multiple tooth part, and the spline on inner periphery is internal spline, and the spline on outer cylinder surface is external splines.Obviously, splined is the development of Flat dey joint on number.Spline is normal structure.Due to the difference of structural type and manufacturing process, compare with Flat dey joint, splined has advantage more in intensity, technique and use; At present, also there is a little flaw in spline housing in making, and as tooth root place stress is concentrated less, the number of teeth is more, and total area of contact is comparatively large, and thus can bear larger load, guidance quality is bad.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides that a kind of structure is simple, the spline housing of long service life.
The technical solution of the utility model is to provide a kind of spline housing, it comprises circular axis body, it is characterized in that: the inner ring of described axis body is provided with the internal spline of several projection, described internal spline is an isosceles trapezoid shape, and the dual-side of described internal spline is provided with the many chutes caved in.
In the utility model preferred embodiment, outer side surface bottom 1/3rd place that a kind of spline housing comprises described axis body is further provided with an annular recess, described groove is provided with the corresponding shrinkage pool arranged of multiple and described internal spline, described shrinkage pool is equidistant setting.
In the utility model preferred embodiment, the both sides that a kind of spline housing comprises described shrinkage pool further are equidistantly provided with projection, and described projection and described shrinkage pool are arranged at sustained height.
In the utility model preferred embodiment, a kind of spline housing comprises described internal spline further and is at least provided with six, is equidistant setting between described internal spline.
In the utility model preferred embodiment, a kind of spline housing comprises described axis body and described internal spline further and is formed in one and arranges.
In the utility model preferred embodiment, a kind of spline housing comprises described axis body further and described internal spline all adopts stainless steel material to make.
Spline housing of the present utility model is equidistantly provided with the internal spline of several projection for increasing friction at the inner ring of axis body, increases driving force; At least arrange six internal splines then because the number of teeth is more, total area of contact is comparatively large, thus can bear larger load; And six internal splines facilitate centering, centering is good, this at a high speed and precision machinery very important.It is simple that the utility model has structure, long service life, low cost and other advantages.

Fig. 2 is the side structure schematic diagram of a kind of spline housing of the utility model most preferred embodiment.
Embodiment
Below embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of spline housing of the present utility model, it comprises circular axis body 1, and the inner ring of axis body 1 is equidistantly provided with the internal spline 2 of several projection, and internal spline 2 is at least provided with six, and the present embodiment is provided with six internal splines 2; Internal spline 2 is an isosceles trapezoid shape, and the dual-side of internal spline 2 is provided with the many chutes caved in 3; Outer side surface bottom 1/3rd place of axis body 1 is provided with an annular recess 4, groove 4 is provided with multiple shrinkage pool 5 of arranging corresponding to internal spline 2, and shrinkage pool 5 is equidistant setting.
The both sides of shrinkage pool 5 are equidistantly provided with protruding 6, and protruding 6 are arranged at sustained height with shrinkage pool 5; Axis body 1 and internal spline 2 are formed in one and arrange; Axis body 1 and internal spline 2 all adopt stainless steel material to make.
Spline housing of the present utility model is equidistantly provided with the internal spline 2 of several projection for increasing friction at the inner ring of axis body 1, increases driving force; At least arrange six internal splines 2 due to the number of teeth more, total area of contact is comparatively large, thus can bear larger load; And six internal splines 2 facilitate centering, centering is good, this at a high speed and precision machinery very important; Annular recess 4, for placing driving tools, groove 4 is provided with multiple shrinkage pool 5 of arranging corresponding to internal spline 2, and the projection 6 that the both sides of shrinkage pool 5 are equidistantly arranged all has increase frictional force and driving force; The spline housing of one-body molded setting is more firm, and stainless material is also more durable.
Above embodiment is only the utility model a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
