Abstract
The utility model relates to a self-rotatable lip seal ring, which is provided with an inequilateral U-shaped framework (1). As a result, the utility model can not generate centrifugal distortion influencing the sealing effect on a lip opening when the seal ring requires self rotation. Therefore, the utility model overcomes the defect that at presently, the rotary shaft lip seal ring which is only supplied by home and abroad markets can lead to sealing failure owing to distortion generation of the diameter of the lip opening for reason of the action of the centrifugal force when the rotary shaft lip seal ring is used for driving devices which requires the seal ring to make self rotation, such as a hydraulic coupler.
Description
The utility model relates to a kind of seal element that self is in the rotation operating mode; Be applicable on the transmission device as fluid coupling and so on that need make seal element self be in the rotation operating mode.
And the seal ring that can supply on the market, home and abroad at present, the title that it is formal, as State Standard of the People's Republic of China GB9877.1～GB9877.3-88 called, be called: " rotary shaft lip seal ".Indicated as its title, this class seal ring is fit to axle rotation, the non-rotary operating conditions of seal ring self; In addition by standard as can be known this class seal ring pressure-bearing be no more than 0.03MPa.At present,, seal ring is under self rotating condition works, and pressure-bearing is during greater than 0.03MPa, the rotary shaft lip seal of still having to select for use when picture fluid coupling this class transmission device; Because have only this class seal ring supply on the market, home and abroad.But find: when rotary shaft lip seal is used in when needing seal ring self rotation, because action of centrifugal force, makes the lip diameter produce distortion and increase, make that magnitude of interference reduces between lip and axle journal, or produce the gap by observing with test; Thereby sealing effect had a negative impact, and then be to make seal failure, cause leakage.
The purpose of this utility model is will provide a kind of to be in self when rotation when seal ring, can overcome the new structure seal ring that centrifugal force has a negative impact to sealing effect-be the lip-type packing of seal ring self rotation.
The purpose of this utility model is achieved in that the skeleton of seal ring changes inequilateral U-shaped skeleton into; Thereby guarantee to overcome effectively the adverse effect of centrifugal force to sealing effect.
The utility model is because only need to change skeleton into inequilateral U-shaped skeleton, so structure is simple especially.Such structure is in when self rotating operating mode seal ring, and the centrifugal distortion of the sealing effect that can not exert an influence on lip has guaranteed the reliable and effective of sealing.Determine that through testing the utility model has the bearing capacity that is not less than 2MPa simultaneously.Therefore this seal ring is particularly suitable for the identical therewith aqueous medium fluid coupling of operating mode.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the sectional drawing according to the lip-type packing of seal ring self rotation that the utility model proposes.
Describe structure and details in detail below in conjunction with Fig. 1 according to the seal ring that the utility model proposes.
The sealing circle comprises seal ring main body [3], inequilateral U-shaped skeleton [1] and lock ring spring [2].The minor face of inequilateral U-shaped skeleton [1] is in lip one side.Because lip one side has had skeleton, so the lip-type packing of this seal ring self rotation can overcome the influence of centrifugal force effectively; Guaranteed lip that effective sealing is required and the magnitude of interference between the axle journal, thus also guaranteed the reliable of sealing with effectively.Owing to lip one side skeleton is arranged also simultaneously, thereby make this class seal ring that the bearing capacity that is not less than 2MPa be arranged.
Claims (1)
1. the lip-type packing of seal ring self rotation.Comprise skeleton and lock ring spring: it is characterized by inequilateral U-shaped skeleton, and its minor face is in lip one side.
