Abstract
The utility model discloses a plane spacer. The plane spacer is provided with two straight end faces. The plane spacer is characterized in that small concave spots are arranged on the outer surface of each straight end face in a dotted mode. The plane spacer has the advantages of improving the lubricating property of a contact surface of the spacer and reducing friction of the contact surface of the spacer.
Description
[technical field]
The utility model relates to a kind of improvement invention of flat pad.
[background technique]
Flat pad is the pad that a kind of both ends of the surface are the plane, the flat pad of in automobile differential, using, the same with spherical pad at differential mechanism housing and gear between install, play and reduce friction and improve lubrication.Differential mechanism should adapt to serious jolt and can be under high and low temperature environment long-term high speed operation.Because the both ends of the surface of the flat pad of using in differential mechanism at present all are smooth, perhaps only be provided with little concave point in a side end face of flat pad, like this in differential mechanism runs up process, the surface of contact of flat pad is lubricated not ideal enough, so operation friction between the part and generation grind wound, can make the differential mechanism temperature too high, part deformation, the rate of fault height, renewal part is frequent, maintenance expenses is big thereby cause.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of flat pad that improves pad surface of contact greasy property, reduces the friction of pad surface of contact.
For solving the problems of the technologies described above, the utility model takes following technological scheme to finish:
A kind of flat pad has two straight end faces, it is characterized in that: the outer surface of two straight end faces is point-like and lays little concave point.Described little concave point is the sphere arc, and the diameter of little concave point is less than 2mm, and the degree of depth of little concave point is less than 1.5mm.
In the technique scheme, because being point-like at the both sides of flat pad end face lays little concave point, little concave point can play the effect of holding oil, so can improve the greasy property between the part that contacts with flat pad both sides end face well, effectively reduce the friction of pad surface of contact, operation friction and the contingent wound of grinding when reducing differential mechanism work between the differential mechanism part, avoid the differential mechanism temperature too high, improve part working life, reduce rate of fault, reduce maintenance expenses.In addition, the above-mentioned design parameter of little concave point can satisfy the lubricating requirement of pad surface of contact well, plays the purpose of the most effective reduction pad surface of contact friction.
[description of drawings]
The utility model has the following drawings:
Fig. 1 is a structural drawing of the present utility model,
Fig. 2 is the axial sectional view of Fig. 1.
[embodiment]
Below come the utility model is done detailed explanation by specific embodiment:
As shown in the figure, flat pad of the present utility model, the outer surface with two straight end face 1, two straight end faces 1 is point-like and lays little concave point 2, and described little concave point 2 is the sphere arc, and the diameter of little concave point 2 is less than 2mm, and the degree of depth of little concave point 2 is less than 1.5mm.
Flat pad of the present utility model, because its both sides end face is point-like and lays little concave point, little concave point plays the effect of holding oil, so improved the greasy property between the part that contacts with flat pad both sides end face, reduces the friction of pad surface of contact.
Claims (2)
1. a flat pad has two straight end faces, it is characterized in that: the outer surface of two straight end faces is point-like and lays little concave point.
2. a kind of flat pad according to claim 1 is characterized in that: described little concave point is the sphere arc, and the diameter of little concave point is less than 2mm, and the degree of depth of little concave point is less than 1.5mm.
