Abstract
The utility model provides a cooperation structure in axle sleeve and shaft hole, it includes an external conjugate diameter and starter casing shaft hole aperture complex axle sleeve, the outer end of axle sleeve is equipped with the flange and blocks in the outside in shaft hole, is equipped with laminated chain on the edge of shaft hole inboard, the inner of axle sleeve is equipped with the shirt rim to rivet the shirt rim side through the riveting and fix a position in laminated chain. The device has increased laminated chain in the inboard in shaft hole to the inner flower tooth that forms at the axle sleeve makes the axle sleeve can both fix a position at axial displacement and rotation in a circumferential direction, has realized having improved reliability of an item.
Description
Technical field
This utility model belongs to automobile starter technical field, particularly to a kind of axle sleeve
And the fit structure between casing axis hole.
Background technology
The casing of automobile starter is provided with axis hole, is inserted in axle sleeve (oil-containing axle in axis hole
Hold), as it is shown in figure 1, in general, axle sleeve and casing are interference fit, by between the two
Extruding fix axle sleeve, and the outside of only axle sleeve is provided with rib, the therefore axle of axle sleeve
Being very poor to motion and circumferencial direction stationarity in fact, the easy loose or dislocation of axle sleeve, impact is produced
The reliability of product.
Summary of the invention
The purpose of this utility model is the problem coordinating axis hole to exist for existing axle sleeve,
And the fit structure that a kind of comprehensive restriction axle sleeve rotates is provided.
The purpose of this utility model can be realized by following technical proposal: a kind of axle sleeve and axle
The fit structure in hole, it includes the axle sleeve of an overall diameter and casing axis hole apertures, institute
The outer end stating axle sleeve is provided with rib and is blocked in the outside of axis hole, it is characterised in that in axis hole
The edge of side is provided with alligator, and the inner of described axle sleeve is provided with shirt rim, and by riveting by skirt
Avris riveting positions in alligator.
Described alligator forms spline along the edge annular array inside axis hole, described axle sleeve
Shirt rim riveting one by one is in spline, and therefore shirt rim also forms colored tooth at outer wall.
Compared with prior art, this device adds alligator in the inner side of axis hole, and at axle sleeve
Inner form flower tooth, it is achieved that two purposes, 1, together with rib, axle sleeve is axially limited
Position；2, the circumference making axle sleeve is spacing, prevents it from rotating, and this device increases in the inner side of axis hole
Add alligator, and formed flower tooth the inner of axle sleeve, it is achieved that two purposes, 1 and gear
Limit is together by axle sleeve axial limiting；2, the circumference making axle sleeve is spacing, prevents it from rotating, carries
The high reliability of product.

Fig. 1 is prior art construction schematic diagram.
Fig. 2 is axis hole schematic diagram of the present utility model.
Fig. 3 is the sectional view of C-C part at Fig. 2.
Fig. 4 is assembling schematic diagram of the present utility model.
In figure, 1, axle sleeve；2, rib；3, axis hole；4, casing；5, spline；6、
Flower tooth.
Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, to this utility model
Technical scheme be further described, but this utility model is not limited to these embodiments.
As shown in Figure 2,3, 4, the axis hole 3 of casing 4 is arranged with an axle sleeve 1, axle sleeve
The outer end of 1 is provided with rib 2, when axle sleeve 1 inserts in axis hole 3, and the outer end rib 2 of axle sleeve 1
It is stuck in the outside of axis hole 3.The inside edge of described axis hole 3 is provided with spline 5, and at axle sleeve 1
Lower end be provided with shirt rim, described shirt rim is embedded in spline 5 by riveting, and with spline 5
One_to_one corresponding forms colored tooth 6.Shirt rim needs to side coil riveting, therefore spends tooth 6 and rib 2
Together by axle sleeve 1 axial limiting；Meanwhile, the circumference making axle sleeve 1 is spacing, prevents it from rotating.
Claims (2)
1. axle sleeve and a fit structure for axis hole, it includes an overall diameter and casing (4)
The axle sleeve (1) of axis hole (3) apertures, the outer end of described axle sleeve (1) is provided with rib (2) and resistance
Keep off the outside in axis hole (3), it is characterised in that the edge of axis hole (3) inner side is provided with alligator,
The inner of described axle sleeve (1) is provided with shirt rim, and the riveting of side, shirt rim is determined in alligator by riveting
Position.
A kind of axle sleeve the most according to claim 1 and the fit structure of axis hole, its feature
Being, described alligator forms spline (5), institute along the edge annular array of axis hole (3) inner side
Stating the shirt rim riveting one by one of axle sleeve (1) in spline (5), therefore shirt rim also forms flower at outer wall
Tooth (6).
