Abstract
A kind of L-type seal combination, including sealing ring and same slip ring shaft；The inside of sealing ring is co-axially located at slip ring shaft；And the inner sidewall of sealing ring is adjacent to same slip ring shaft, forms seal combination；Seal combination is arranged in annular groove；Cross section with slip ring shaft is L-type；The concave surface of same slip ring shaft L-type is arranged in sealing ring.Slip ring and protection retaining ring are carried out integrated design by the utility model, are reduced combination sealing amount of parts, are facilitated installation.After slip ring and guard circle carry out integrated design, O-ring seal is mounted on the inside of same slip ring shaft, and there will be no may squeeze into gap, improve overall performance and the service life of combination sealing.
Description
Technical field
The utility model belongs to technical field of sealing technology, in particular to a kind of L-type seal combination.
Background technique
Sealing ring is widely used in traditional mechanical-hydraulic, air pressure product, the medium sealed can be gas,
Liquid or powder etc..The problems such as bad breakdown maintenance that will cause product of sealing, external leakage pollute.Sealing is mainly comprising fixing
Sealing and movable sealing when fixing seal, do not have relative motion between sealing ring and counterface, it is general require to guarantee it is absolutely close
Envelope is not allow for leaking；When movable sealing, there is relative motion between sealing ring and counterface, generally there is stringent leakage to want
It asks.Movable sealing generally uses combined labyrinth and carbon gland, increases retaining ring between sealing ring and the face that is slidably matched, and passes through retaining ring and sliding
Mating surface rubs, and improves friction durability and frictional force, and axis generally uses step sealing structure with sealing.
Traditional axis is mainly that O-ring seal and outside have step bevel edge slip ring with this spy's envelope of combination sealing, in reality
It is had the following deficiencies in use process:
1) it at for some pressure, the higher sealing structure of the speed of service, needs to install in the side of slip ring and sealing ring
Retaining ring prevents oil pressure in motion process from squeezing into O-ring seal in the gap of slip ring and seal groove side, protects in installation process
Installation part becomes more after circle is seperated, inconvenience installation.
2) in actual use, O-ring seal still can squeeze into the gap between guard circle and slip ring once in a while
Cause local damage or deformation.
Utility model content
The purpose of this utility model is to provide a kind of L-type seal combinations, to solve the above problems.
To achieve the above object, the utility model uses following technical scheme:
A kind of L-type seal combination, including sealing ring and same slip ring shaft；The inside of sealing ring is co-axially located at slip ring shaft；
And the inner sidewall of sealing ring is adjacent to same slip ring shaft, forms seal combination；Seal combination is arranged in annular groove；Same slip ring shaft
Cross section be L-type；The concave surface of same slip ring shaft L-type is arranged in sealing ring.
Further, the position contacted with slip ring shaft with sealing ring is arc-shaped, and size and the sealing ring of circular arc match.
Further, there is protrusion with peripherally disposed on the ring inner sidewall of slip ring shaft.
Further, protrusion is wedge protrusion.
Further, seal combination is arranged in annular groove, and same slip ring shaft is close in the side of sealing ring, and the other side is close to
The inner sidewall of annular groove.
Further, sealing ring is O-ring seal.
Compared with prior art, the utility model has following technical effect:
Slip ring and protection retaining ring are carried out integrated design by the utility model, reduce combination sealing amount of parts,
Facilitate installation.After slip ring and guard circle carry out integrated design, O-ring seal is mounted on the inside of same slip ring shaft, and there will be no can
It can squeeze into gap, improve overall performance and the service life of combination sealing.
The utility model is arc-shaped with the position that slip ring shaft is contacted with sealing ring, contacts it with sealing ring closer.
The utility model, so that seal combination is at work, effectively increases with protrusion is provided on the ring inner sidewall of slip ring shaft
The local stress of big convex portion, makes to seal closer.
Detailed description of the invention
Fig. 1 is the utility model perspective view；
Fig. 2 is the utility model sectional view.
Wherein: 1, sealing ring；2, same to slip ring shaft.
Specific embodiment
Below in conjunction with attached drawing, the present invention will be further described:
Please refer to Fig. 1 and Fig. 2, a kind of L-type seal combination, including sealing ring 1 and with slip ring shaft 2；It is coaxially set with slip ring shaft 2
It sets in the inside of sealing ring 1；And the inner sidewall of sealing ring 1 is adjacent to same slip ring shaft 2, forms seal combination；Seal combination setting
In annular groove；Cross section with slip ring shaft 2 is L-type；The concave surface of same slip ring shaft L-type is arranged in sealing ring 1.
The position contacted with slip ring shaft 2 with sealing ring 1 is arc-shaped, and size and the sealing ring 1 of circular arc match.
There is protrusion with peripherally disposed on the ring inner sidewall of slip ring shaft 2.
Protrusion is wedge protrusion.
Seal combination is arranged in annular groove, and the side of sealing ring 1 is close to slip ring shaft 2, and it is recessed that annular is close in the other side
The inner sidewall of slot.
Sealing ring 1 is O-ring seal.
By taking sleeve as an example, lateral edge side wall is provided with one week annular groove in sleeve, and seal combination is arranged in annular groove
Interior, sealing ring is close to annular groove inner sidewall；Movable axis is set in sleeve, and movable axis squeezes seal combination protrusion, and increase connects
The extruding force of contact portion point, sealing ring are close to same slip ring shaft, to realize sealing；When movable axis moves back and forth, with slip ring shaft and
The inner sidewall of annular groove is clamped sealing ring, enhances sealing effect while placing sealing ring and being got into gap.
