Abstract
The utility model provides a sealing device used between a gyro shaft and a stationary part, comprising the components such as the gyro shaft, the stationary part and a stationary end cover, and is characterized in that a spiral groove is arranged on the stationary end cover; a return chute is also arranged on an under-part of the stationary end cover; the sealing device has the advantages of simple structure, easy machining, reliable sealing, friction-free, heating-free, abrasion-free, damage-free of the shaft and long service life.
Description
Technical field:
The utility model relates to a kind of seal arrangement that is used between turning axle and the static element, belongs to mechanized equipment lubrication and seal technical field.
Background technique:
Rotary sealing belongs to motive sealing, and it should guarantee the sealing between turning axle and the static element, and frictional heating and the wearing and tearing controlling in the relative movement again to be produced are so the difficulty of its sealing is more much bigger than static seal.The seal arrangement of taking in rotation motion at present has 4 kinds of seal ring sealing, felt ring seal, labyrinth seal and mechanical seals.But these 4 kinds of seal arrangements belong to same class sealing means: promptly all be the angle from passiveness, what take is " blocking up ", " preventing " measure, fluid its defence line of in a single day dashing forward, and sealing will be lost efficacy.Sometimes people can increase the sealing of several roads more, and attempt is camped step by step and reached leak free purpose, but along with the continuity of rotation motion, and Sealing still can wear out, can wearing and tearing, and the oil mass that brought out by turning axle this moment can increase gradually, finally causes a large amount of leakages.Therefore, passive leakage protection device can only be controlled table, can not effect a permanent cure.
Summary of the invention:
The purpose of this utility model just provides a kind of seal arrangement that is used between turning axle and the static element, and the sealing device does not have leakage phenomenon to be taken place.
The purpose of this utility model can realize by following scheme: comprise parts such as turning axle, static element and static end cap, it is characterized in that covering in stationary end and be provided with spiral chute, also be provided with oil-return groove in static end cap bottom.
The utlity model has following advantage:
(1) simple in structure, easy processing, sealing is reliable;
(2). there are not friction, heating and wearing and tearing, to the axle not damaged;
(3). long service life.
Description of drawings:
Fig. 1 the utility model structural representation
Embodiment:
Contrast Fig. 1 as can be known, the utility model comprises parts such as turning axle 1, static element 2 and static end cap 3, it is characterized in that being provided with on static end cap 3 spiral chute 4, also is provided with oil-return groove 5 in static end cap 3 bottoms.
The utility model working principle is: utilize the principle of spiral motion, make the oily foam that just is thrown between turning axle and the static element, flow back to fuel tank automatically along spiral chute among, thereby reach the leak free purpose of effecting a permanent cure of taking stopgap measures.
Claims (2)
1, a kind of seal arrangement that is used between turning axle and the static element comprises turning axle (1), static element (2) and static end cap (3), it is characterized in that being provided with on static end cap (3) spiral chute (4).
2, seal arrangement according to claim 1 is characterized in that also being provided with oil-return groove (5) in static end cap (3) bottom.
