Abstract
A special-shaped skeleton rubber sealing ring comprise a special-shaped skeleton (1) and nitrile-butadiene rubber (2). The special -shaped skeleton (1) is embedded in the nitrile-butadiene rubber (2); and the special-shaped skeleton (1) plays the role of overall supporting, and the nitrile-butadiene rubber (2) plays the role of overall sealing. The technical characteristics are as below: bending (shown in Figure 1, 1) is arranged on the skeleton of the rubber sealing ring to increase the rigidity of the skeleton; blended flanging ensures firm bonding with rubber; when mounted in a bearing sealing groove, the sealing ring does not distort under the effect of mechanical pressure, so as to achieve a good the sealing effect.
Description
Affiliated technical field:
What patent of the present invention related to is bearing rubber seal ring framework rigidity, belongs to the technological innovation of bearing application.
Background technique:
The structural type of stuffing box bearing skeleton rubber seal ring used is many, seal ring skeleton used is all the standardized designs that adopts former Ministry of Machine-building and Electronics Industry seal ring skeleton, the skeleton rubber seal ring of this structure has the following disadvantages: the one, and the rigidity of skeleton is inadequate, be subject to the impact of bearing space position, skeleton sheet material can not design too thickly and select too hard material, too thick seal space position is inadequate, too firmly not flexible or bending rear frangibility, therefore skeleton rubber seal ring is in manufacturing procedure with in being installed on bearing, be easy to produce distortion, cause sealability to lose efficacy, the 2nd, skeleton and rubber bonding insecure, skeleton rubber seal ring when stressed easily cracking come unstuck.
Summary of the invention:
In order to improve rubber seal ring framework rigidity and sealability, the present invention adopts a kind of special-shaped skeleton rubber seal (seeing Fig. 1), skeleton to rubber seal is provided with bending, increase the rigidity of skeleton, bending flanging is more firm while making rubber bonding with it, and seal ring is in being installed in bearing seal groove, under the effect of mechanical pressure, can not produce distortion, thereby reach good sealing effect.The technical solution adopted in the present invention is: a kind of special-shaped skeleton rubber seal, formed by special-shaped skeleton (1) and nitrile rubber (2), abnormity skeleton (1) is embedded in the inside of nitrile rubber (2), abnormity skeleton (1) plays integrated support effect, and nitrile rubber (2) plays integral sealing effect; Its technical characteristics is: the skeleton to rubber seal is provided with bending.
The technical problem solving:
In order to solve seal ring skeleton rigidity and the sealing problem mentioned in foregoing, the present invention is achieved by the following technical solutions: utilize the skeleton bending of rubber seal, increase the rigidity of skeleton; Flanging also makes rubber more firmly bonding with it, and seal ring, in the time being installed in bearing seal groove, under the effect of mechanical pressure, can not producing distortion, thereby reach good sealing effect.
The invention has the beneficial effects as follows:
Can effectively solve the variety of problems that skeleton rubber seal ring degree of adhesion is bad, sealing is poor, easy cracking comes unstuck.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention.
Embodiment:
As shown in fig. 1, skeleton rubber sealed bearing is made up of special-shaped skeleton (1) and nitrile rubber (2), it is characterized in that the skeleton of rubber seal to be provided with bending (seeing 1 in Fig. 1), increase the rigidity of skeleton, bending flanging is more firm while making rubber bonding with it, and seal ring is in being installed in bearing seal groove, under the effect of mechanical pressure, can not produce distortion, thereby reach good sealing effect.Special-shaped skeleton rubber seal after improving has been applied on the stuffing box bearings such as 6201,6202,6203,6204, these bearings are in the time installing seal ring, abnormity skeleton rubber seal distortion free, in the time doing tearing test, abnormity skeleton rubber seal ring from bonding is firm, without coming unstuck and cracking phenomena.
Claims (1)
1. a special-shaped skeleton rubber seal, formed by special-shaped skeleton (1) and nitrile rubber (2), abnormity skeleton (1) is embedded in the inside of nitrile rubber (2), abnormity skeleton (1) plays integrated support effect, and nitrile rubber (2) plays integral sealing effect; Its technical characteristics is: the skeleton to rubber seal is provided with bending.
