Description
Technical Field
The invention relates to the technical field of seal member replacement operation, in particular to tooling equipment and a method for a bidirectional lip seal assembly of a front end cover of a hydraulic motor.
Background
The bidirectional lip sealing assembly is a sealing device capable of sealing in two directions, and can isolate sealing cavities on two sides of a lip to prevent intercommunication. Generally, the sealing component is formed by taking a skeleton made of polyoxymethylene as a supporting frame, arranging a groove in the center of the outer circle of the supporting frame, placing an O-shaped ring to form a static seal on the outer circumferential surface, arranging a groove on the inner circumferential surface of the supporting frame, placing a bidirectional lip seal made of polyurethane to isolate cavities on two sides of a to-be-sealed piece, and as shown in fig. 1, the bidirectional lip seal component 101 is used for preventing external media from entering the inside of a front end cover 102 (shown as a front end cover of a hydraulic motor) of the hydraulic motor, and simultaneously preventing internal media from overflowing outside. In actual operation, lips under the action of pressure on two sides of the sealing assembly are pressed on the to-be-sealed piece to form effective face seal.
In the prior art, the sealing assembly needs to be disassembled and reassembled when the sealing assembly is replaced, and when the sealing assembly is disassembled, the first step is that after a clamping spring for axially positioning the sealing element is taken out, a plastic ring is placed in a clamping spring groove; secondly, screwing the bolt into a threaded hole of the sealing assembly; and thirdly, taking out the sealing assembly by applying tension to the bolts. In the method, the O-shaped ring on the outer circular surface of the supporting framework is compressed, the bidirectional lip seal on the inner circular surface is also compressed, and when the sealing assembly is pulled out outwards, namely the third step is carried out, the friction force on the inner circular surface and the outer circular surface of the sealing assembly is very large, unbalance is very easy to occur when tension is applied, and the dismantling process is often destructive and is very time-consuming and labor-consuming. In the same way, during reinstallation, in the first step, after the snap springs for axially positioning the sealing element are taken out, the plastic ring is placed in the snap spring groove; secondly, sleeving the sealing assembly on a shaft to be sealed; because the lips on the inner circular surface of the sealing component shrink inwards, the inner diameter of the lips is slightly smaller than the outer diameter of the shaft, the lips need to be carefully operated in the process of sleeving the shaft to be sealed, the problem that the O-shaped rings on the outer circular surface of the sealing component are crushed and damaged easily and the lips on the inner circular surface are crushed and turned over to lose efficacy is easily caused, and the normal use of the device is affected. Thirdly, pressing the sealing assembly into place by using an intermediate ring; and fourthly, taking out the middle ring and the plastic ring.
The above process can be seen how to conveniently, efficiently and rapidly disassemble and replace the sealing assembly and avoid damage to the sealing assembly during the replacement process, which is a technical problem to be solved in the art.
Therefore, in view of the above-mentioned drawbacks, the designer of the present invention, through intensive research and design, combines the experience and achievement of related industries for a long period of time, and designs a tooling device and method for a bi-directional lip seal assembly of a front end cover of a hydraulic motor, so as to overcome the above-mentioned drawbacks.
