Abstract
The utility model discloses a novel sealing ring of a spherical plain bearing, which comprises a ring body and a sealing lip, wherein the lower side surface of the sealing lip is provided with a first oblique angle relative to the ring body, and an annular flange is arranged between the upper surface of the ring body and the sealing lip; and a raised annular lip is arranged on the lower side surface of the ring body. Compared with the prior art, the raised annular lip is arranged on the lower side surface of the ring body, as a result, a labyrinth groove can be formed between the sealing lip and the annular lip, when dust enters the sealing lip, through the blocking of the annular lip, the dust falls into the labyrinth groove formed between the sealing lip and the annular lip, and thereby the utility model effectively prevents the dust from entering the inside of the spherical plain bearing, and the service life of the spherical plain bearing is prolonged, when the sealing lip is worn to a certain degree, the annular lip also can play an important role of sealing, double seal is utilized, so the sealing effect is good.
Description
Technical field
The utility model relates to a kind of joint shaft bearing Sealing, relates in particular to a kind of seal ring of joint shaft bearing.
Background technique
The sealing problem of various axial workpieces is perplexing machine building industry always, although all kinds of Sealing emerges in an endless stream, does not fundamentally solve the leakage problem of machine (as joint shaft bearing) yet.Main cause is that the conventional seals circle has only a sealing lip limit, and it is aging or damaged easily as the material of seal ring, in case break or wear and tear in the sealing lip limit of this seal ring, just cause seal ring to lose efficacy, make dust easily invade in the joint shaft bearing, thereby aggravate the wearing and tearing of joint shaft bearing, cause shortening the working life of joint shaft bearing.
The model utility content
The purpose of this utility model provides a kind of good sealing effect, can prevent effectively that dust from entering the novel joint shaft bearing seal ring of bearing inside.
The technical solution of the utility model is such: a kind of novel joint shaft bearing seal ring, comprise circle body and the sealing lip limit of being located at the circle body inboard, the downside on its sealing lip limit has first oblique angle with respect to circle body, is provided with annular rib between the upper side of above-mentioned circle body and above-mentioned sealing lip limit; The downside of described circle body is provided with the annular lip of projection.
Described annular lip has second oblique angle with respect to circle body, and above-mentioned first oblique angle is consistent with the true dip direction at second oblique angle.
After adopting technique scheme, a kind of novel joint shaft bearing seal ring of the present utility model is provided with protruding annular lip on the downside of circle body.Compared with prior art, on the downside of circle body, be provided with the annular lip of projection, like this, can form a maze trough between sealing lip limit and annular lip, when dust enters the sealing lip limit, by stopping of annular lip, dust is rested in the maze trough that forms between sealing lip limit and annular lip, thereby prevent that effectively dust from entering joint shaft bearing inside, make the working life of joint shaft bearing longer, and when the sealing lip limit may wear to a certain degree, annular lip also can play main seal action, then utilize double-layer seal, good sealing effect; Because annular lip has second oblique angle with respect to circle body, and this second oblique angle is consistent with the true dip direction at first oblique angle, can more effectively stop dust to enter joint shaft bearing inside like this, has further improved the working life of joint shaft bearing.

Fig. 2 is the enlarged view of A portion among Fig. 1.
Embodiment
A kind of novel joint shaft bearing seal ring of the present utility model, as shown in Figure 1, 2, direction with the seal ring horizontal positioned is come description scheme, comprise circle body 1 and the sealing lip limit 2 of being located at circle body 1 inboard, 2 on the upper side of circle body 1 and sealing lip limit are provided with annular rib 3, the downside on sealing lip limit 2 has acclivitous first oblique angle with respect to circle body 1, and the downside of circle body 1 is provided with the annular lip 4 of projection, and annular lip 4 has acclivitous second oblique angle with respect to circle body 1.
A kind of novel joint shaft bearing seal ring of the present utility model, on the downside of circle body 1, be provided with the annular lip 4 of projection, like this, 4 of sealing lip limit 2 and annular lip can form a maze trough, when dust enters sealing lip limit 2, by stopping of annular lip 4, dust is rested in the maze trough of sealing lip limit 2 and 4 formation of annular lip, thereby prevent that effectively dust from entering joint shaft bearing inside, make the working life of joint shaft bearing longer, and when sealing lip limit 2 may wear to a certain degree, annular lip 4 also can play main seal action, then utilize double-layer seal, good sealing effect; Because annular lip 4 has acclivitous second oblique angle with respect to circle body 1, and this second oblique angle is consistent with the true dip direction at first oblique angle on sealing lip limit 2, can enter joint shaft bearing inside by more effective prevention dust like this, further improve the working life of joint shaft bearing.
Claims (2)
1. a novel joint shaft bearing seal ring comprises circle body and the sealing lip limit of being located at the circle body inboard, and the downside on its sealing lip limit has first oblique angle with respect to circle body, is provided with annular rib between the upper side of above-mentioned circle body and above-mentioned sealing lip limit; It is characterized in that: the downside of described circle body is provided with the annular lip of projection.
2. a kind of novel joint shaft bearing seal ring according to claim 1, it is characterized in that: described annular lip has second oblique angle with respect to circle body, and above-mentioned first oblique angle is consistent with the true dip direction at second oblique angle.
