Abstract
The utility model discloses self-centering spherical pads, and there is spherical surface body, the spherical surface body center to be equipped with through-hole, it is characterised in that：The Internal Spherical Surface of the spherical surface body is equipped with spiral groove, and the spherical outside surface of the spherical surface body is equipped with the oil guiding hole communicated with the spiral groove, and the outer rim of the spherical surface body is additionally provided with the annular flange upwarped.The utility model can effectively improve the greasy property of gasket, reduce the friction of pad contacting surface, extend gasket service life.
Description
Technical field
The utility model is related to pad fields, and in particular to self-centering spherical pad.
Background technology
Spherical pad is the gasket that a kind of both ends of the surface are spherical surface, it is mainly used on automobile differential, and differential mechanism is answered
Adapt to it is serious jolt and can under high and low temperature environment long-term high-speed cruising, spherical pad is as a kind of gasket, it is in differential mechanism
Shell and Hindley worm gear between install, play reduction friction and improve lubricating action.Due to current used spherical pad
Both ends of the surface be all smooth, or only the Internal Spherical Surface of spherical pad be equipped with small concave point, ran at high speed in this way in differential mechanism
The contact surface lubrication of Cheng Zhong, spherical pad are not ideal enough, and the friction between contact surface is larger, is susceptible to failure.
For the high spherical pad of some spherical outside surface required precisions, need by grinding, but spherical pad itself is justified
It is sliding, it is difficult to have reliable clamping point on clamp, prodigious trouble can be caused.In addition, spherical pad is in differential casing
It is free installation between Hindley worm gear, radial position is easy movement when work, although spherical surface connecing of can eliminating that its movement brings
Touch deviation influences service life it is apparent that being unfavorable for the contact friction of spherical pad.
In addition, spherical pad is easy to generate scrap because of abrasion in use, these scrap, which enter in equipment, to be easy to influence to set
Standby accurate operating.
Utility model content
In view of the deficiency of background technology, the technical problem to be solved by the utility model is to provide the lubrications that can improve gasket
Performance, the friction for reducing contact surface and the self-centering spherical pad for facilitating installation to position.
To achieve the above object, the utility model provides following technical solution：
There is self-centering spherical pad spherical surface body, the spherical surface body center to be equipped with through-hole, it is characterised in that：The spherical surface
The Internal Spherical Surface of body is equipped with spiral groove, and the spherical outside surface of the spherical surface body is equipped with the oil guiding hole communicated with the spiral groove, described
The outer rim of spherical surface body is additionally provided with the annular flange upwarped.
Arc groove is formed between the annular flange and the spherical surface body.
Using above technical scheme, lubricating oil can swimmingly be imported in the spiral groove of Internal Spherical Surface, and keeps lubricating oil logical
It crosses through-hole to penetrate on spherical outside surface, improves the greasy property of the utility model, reduce the friction of contact surface, meanwhile, annular flange
It can be used as at the clamping of clamp, be convenient for grinding, and be correspondingly arranged locating slot on differential casing, so that ball ring
Piece obtains accurately installing positioning at work, and then improves service life.Meanwhile being formed between annular flange and spherical surface body
Arc groove can store the scrap that gasket is in contact with it the whereabouts that rubs between part, and scrap is avoided to influence the high speed fortune of equipment
Row, arc groove also allow for clearing up.
Description of the drawings
The utility model has following attached drawing：
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the rearview of Fig. 1；
Fig. 3 is the sectional view of Fig. 1.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown, self-centering spherical pad, there is spherical surface body 1,1 center of the spherical surface body to be equipped with through-hole 2, the spherical surface
The Internal Spherical Surface of body 1 is equipped with spiral groove 3, and the spherical outside surface of the spherical surface body 1 is equipped with the oil guiding hole 4 communicated with the spiral groove 3,
The outer rim of the spherical surface body 1 is additionally provided with the annular flange 5 upwarped.Arc is formed between the annular flange 5 and the spherical surface body 1
Groove 6.
Using above technical scheme, lubricating oil can be injected close to one end of annular flange 5 along spiral groove 3, utilize spiral
The helical structure of groove 3, along the direction rotation spherical body 1 of spiral groove 3 so that lubricating oil is along spiral groove 3 by extroversion
Spiral groove 3 is inside filled up, in the process, lubricating oil is penetrated by through-hole 4 on spherical outside surface, effectively improves the profit of spherical surface body 1
Slip energy reduces the friction of contact surface, meanwhile, annular flange 5 can be used as at the clamping of clamp, be convenient for grinding, and
Locating slot is correspondingly arranged on differential casing, so as to can obtain accurately installing positioning when the utility model at work, in turn
Improve service life.Meanwhile the arc groove 6 formed between annular flange 5 and spherical surface body 1 can store gasket and be in contact with it zero
Rub the scrap of whereabouts between part, and scrap is avoided to influence the high-speed cruising of equipment, and arc groove 6 also allows for clearing up.
