Abstract
The utility model discloses a novel sealing ring, comprising a sealing ring body, the inside of the sealing ring body is provided with a convex sealing lip. via adopting the above technical scheme, the novel sealing ring in the utility model is characterized in that an annular convex sealing lip is added at the inside of the sealing ring body. Compared with the prior art, an annular convex sealing lip is added at the inside of the sealing ring body. In such way, via the annular sealing lip, the sealing ring body is provided with a double-layer sealing, when the sealing ring body ruptures and wears, the annular sealing lip can take a main effect of sealing, is advantaged by good sealing effect, and can effectively prevent the intrusion of dust and slush, and prevent the drainage of the lubricating grease in the cross axle head, enabling the needle roller and the cross axle to rotate flexibly, thereby reducing wear as well as prolonging service life of cross axle.
Description
Technical field
The utility model relates to a kind of Sealing, relates in particular to a kind of seal ring of Hooke's joint.
Background technique
Hooke's joint, especially non-maintaining Hooke's joint can remain lubricating status preferably in order to make spindle nose and needle roller in the outer ring in various working environments, a seal ring need be set in the end of outer ring.In the prior art, usually one of employing or two O RunddichtringOs seal, but this O RunddichtringO does not have the sealing lip limit, and the material as seal ring is aging or damaged easily, in case this seal ring is broken or weares and teares like this, just causes seal ring to lose efficacy, make the interior grease of spindle nose to leaking, make between needle roller and cross-axis head and can not rotate flexibly, thereby aggravate both wearing and tearing, caused shortening the working life of Hooke's joint.
The model utility content
The purpose of this utility model provides a kind of good sealing effect, can effectively prevent the novel seal circle that the grease in the spindle nose outwards releases.
The technical solution of the utility model is such: a kind of novel seal circle, comprise the seal ring body, and the inboard of above-mentioned seal ring body convexes with the annular seal lip limit.
Above-mentioned seal ring upper part of body inboard convexes with the first annular seal lip limit, and the lower inside of above-mentioned seal ring body convexes with the second annular seal lip limit.
After adopting technique scheme, a kind of novel seal circle of the present utility model has additional the annular seal lip limit in the inboard of seal ring body.Compared with prior art, have additional the annular seal lip limit in the inboard of seal ring body, like this, by this annular seal lip limit, make the seal ring body have double-layer seal, when the seal ring body breaks or weares and teares, main seal action can be played in the annular seal lip limit, good sealing effect, thereby can prevent the intrusion of dust, muddy water effectively, and the releasing of lubricant grease in the cross axle spindle nose, needle roller and cross-axis head intercropping are rotated neatly, thereby reduce wear, prolonged the working life of cross axle; Owing to be respectively equipped with the first annular seal lip limit and the second annular seal lip limit on the upper inner of sealing circle body and the lower inside, can form a circular groove between the such first annular seal lip limit and the second annular seal lip limit, when grease leaks the second annular seal lip limit, by stopping of the first annular seal lip limit, grease is rested in the circular groove that forms between the first annular seal lip limit and the second annular seal lip limit, thereby prevent that effectively grease from leaking away, utilize double-lip seal, sealing effect is better.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Among the figure:
1-seal ring body; The 2-first annular seal lip limit; The 3-second annular seal lip limit; The 4-circular groove.
Embodiment
A kind of novel seal circle of the present utility model, as shown in Figure 1, direction with the seal ring horizontal positioned is come description scheme, comprise seal ring body 1, the upper inner of seal ring body 1 and lower inside outwards convex with the first annular seal lip limit 2 and 3, the first annular seal lip limits 2, the second annular seal lip limit and 3 on the second annular seal lip limit respectively can form a circular groove 4.
A kind of novel seal circle of the present utility model, upper inner and lower inside at seal ring body 1 outwards convex with the first annular seal lip limit 2 and the second annular seal lip limit 3 respectively, like this, when seal ring body 1 breaks or weares and teares, main seal action can be played in the first annular seal lip limit 2 or the second annular seal lip limit 3, utilize double seal, good sealing effect, thereby can prevent dust effectively, the intrusion of muddy water, and the releasing of lubricant grease in the cross axle spindle nose, needle roller and cross-axis head intercropping are rotated neatly, thereby reduce wear, prolonged the working life of cross axle; Because the first annular seal lip limit 2 and 3 on the second annular seal lip limit can form a circular groove 4, when grease outwards releases to the second annular seal lip limit 2, by stopping of the first annular seal lip limit 3, grease is rested in the circular groove 4 of the first annular seal lip limit 2 and 3 formation in the second annular seal lip limit, thereby prevent that effectively grease from leaking, then utilize double-layer seal, sealing effect is better.
Claims (2)
1. a novel seal circle comprises the seal ring body, it is characterized in that: convex with the annular seal lip limit on the inner side surface of above-mentioned seal ring body.
2. a kind of novel seal circle according to claim 1 is characterized in that: convex with the first annular seal lip limit on the above-mentioned seal ring upper part of body inner side surface, convex with the second annular seal lip limit on the lower inside of above-mentioned seal ring body is interior.
