Abstract
The utility model discloses a kind of self-lubricating seal ring, it comprises seal ring body (1), in seal ring body (1), be provided with a through hole (4), seal ring body (1) two ends respectively offer an annular boss (2), on through hole (4) inwall, offer groove (3).The beneficial effects of the utility model are: in groove, pile lubricating grease, realized the selflubricating of seal ring, also increased the working life of seal ring simultaneously, thereby sealing ring has advantages of selflubricating and long service life.
Description
Technical field
The utility model relates to Sealing, particularly a kind of self-lubricating seal ring.
Background technique
Seal ring is a kind of annular seal jaggy of being with, and it is placed in the annular groove of sleeve, and sleeve rotates together with axle, and seal ring is held together the rear elasticity having by pressure and is pushed against on the inner hole wall of static element by breach, can play the effect of sealing.Each contact surface all needs through cure process polishing.
In field of sealing technology, in numerous seal means, adopt seal ring axle part to be sealed very general, existing seal ring is various, cannot selflubricating but mostly be, for the frequent axle part that slides of needing, if there is no lubrication assistant measure, friction factor between seal ring and axle part is larger, causes very soon the heavy wear of seal ring, until seal action was lost efficacy.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of long service life and seal ring that can selflubricating are provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of self-lubricating seal ring, and it comprises seal ring body, is provided with a through hole in seal ring body, seal ring body two ends respectively offer an annular boss, offer groove on through-hole wall.
The annular boss size shape at described seal ring body two ends is consistent.
Described groove is spiral groove.
The starting point of described groove and end end are all no more than annular boss 1/2nd places.
The utlity model has following advantage: the utility model in use, realize selflubricating, alleviated the wearing and tearing of seal ring and axle contact position, extended the working life of seal ring and axle part, because lubricating grease itself has sealing effect, also increased sealing effect simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-seal ring body, 2-annular boss, 3-groove, 4-through hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of self-lubricating seal ring, it comprises seal ring body 1, in seal ring body 1, be provided with a through hole 4, seal ring body 1 two ends respectively offer an annular boss 2, and annular boss 2 size shape at seal ring body 1 two ends are consistent, on through hole 4 inwalls, offer groove 3, groove 3 is spiral groove, and lubricating grease is piled in spiral groove the inside, and the starting point of groove 3 and end end are all no more than 1/2nd places of annular boss 2.Before seal ring body 1 is arranged on associated workpiece, in groove 3, pile lubricating grease, thereby make seal ring in use, realize selflubricating, the wearing and tearing of seal ring and axle contact position have been alleviated, extend the working life of seal ring and axle part, because lubricating grease itself has sealing effect, also increased sealing effect simultaneously.
