Abstract
The utility model relates to a two direction sealing type shaft seal, which is shaft seal component which is used in a semi-closed compressor. A sealing lip of the shaft seal is provided with three layers, with the sequential arrangement that a dustproof lip, a forward lip, and a reversal lip. A lip opening of the dustproof lip is perpendicular to a shaft line of the shaft seal, a lip opening of the forward lip is inclined towards one side of the dustproof lip, and a lip opening of the reversal lip is oblique and opposite to the tendency direction of the forward lip. The dustproof lip, the forward lip, and the reversal lip are arranged in sequence, and are positioned in a supporting frame. A circle of grooves are arranged on an outer circle of the supporting frame, and a sealing ring is arranged on the grooves. The forward lip adopts the mixture of graphite, glass powder, and polytetrafluoroethylene.
Description
The utility model is the axle envelope parts of a kind of use in accessible compressor, especially a kind of axle envelope of using at vortex or vehicle compressor.
In accessible compressor, the axle envelope is an important components, to using the automotive air-conditioning system of R134a working medium, require that the axle envelope of compressor has that the burn into of anti-R134a is wear-resisting, the feature of self-lubricating, good seal performance, in addition, give when vacuumizing in the compressor machine, also require the axle envelope to have good reverse sealing function.And such envelope of using at present has only primary seal lip and sealing lip, because the effect of negative pressure in the machine, exterior dust tend to seal from this axle and enter, thereby wearing and tearing that cause axle to seal, make the sealing property variation of axle envelope, cause the mechanical efficiency of whole compressor to reduce the most at last.
Goal of the invention of the present utility model just provides a kind of two way seal axle envelope with dust reduction capability, wear-resisting, good seal performance.
Two way seal axle envelope of the present utility model is made up of support, seal ring and sealing lip, the sealing lip of this envelope has three layers, serial arrangement is dust excluder lips, positive labiad, reverse lip, the lip of dust excluder lips is perpendicular to the axis of this envelope, the lip of positive labiad tilts on one side to dust excluder lips, and oppositely the lip of lip is opposite with the direction of tilt of positive labiad, and dust excluder lips, positive labiad, reverse lip serial arrangement also are positioned at support, on the cylindrical of support, be provided with a ring recess, on groove, be provided with seal ring.The material that positive labiad adopts is the compound of graphite, glass powder and polytetrafluoroethylene.
Advantage of the present utility model is:
1. have good dustproof effect: owing to set up dust excluder lips again outside the primary seal lip is positive labiad, therefore, the outer dust of this envelope is difficult for entering the primary seal lip, has prevented the wearing and tearing and the pollution condition that cause after dust enters effectively.
2. good seal performance: be provided with two positive labiads of opposite sense bevelled and reverse lip, outwards can effectively seal up in the machine and outside bidirection press in machine, promptly have the function of double containment, also be provided with a dust excluder lips simultaneously, can further improve the leak free effect.
3. wear resisting property is good: positive labiad adopts the composite material of glass powder, graphite, polytetrafluoroethylene, and not only self-lubricating property is good, and the abrasion resistant performance is good especially.
Fig. 1 is an overall structure scheme drawing of the present utility model.Comprising dust excluder lips 1, positive labiad 2, reverse lip 3, support 4, truss 41, seal ring 5.
Embodiment of the present utility model is as follows:
Support 4 is a hollow annulus, and serial arrangement has dust excluder lips 1, positive labiad 2, reverse lip 3 in support, and dust excluder lips 1 is positioned at the outer end of axle envelope, and its lip points to the center of circle perpendicular to the axis of axle envelope.Positive labiad 2 is the primary seal lip in dust excluder lips with oppositely between the lip, and the lip of positive labiad is to the dust excluder lips lopsidedness, the angle about the axis that seals with axle is at 45.Oppositely the lip of lip 3 is opposite with the lip direction of tilt of positive labiad, wherein dust excluder lips 1 and oppositely " HNBR " rubber manufacturing of the anti-R134a corrosion of lip 3 employings, and the mixture that positive labiad uses 5% graphite, 21% glass powder, 74% polytetrafluoroethylene mix is made, and this positive labiad has good resistance to abrasion.On the excircle of support 4, be provided with a ring recess 41, on groove 41, be provided with a seal ring 5.According to the above, just can realize the utility model.
