Abstract
The utility model discloses a rotary sealing element which comprises a square sealing ring (1) and a slip ring (2), wherein the square sealing ring (1) is installed on the outer circumferential surface of the slip ring (2), a plurality of friction grooves (21) capable of increasing the friction between the slip ring and the square sealing ring are formed in the outer circumferential surface of the slip ring (2), and an oil storage groove (22) is formed in the inner circumferential surface of the slip ring (2). According to the rotary sealing element, due to the adoption of the sealing structure in which the square sealing ring and the slip ring are combined, sealing stress of the square sealing ring is distributed evenly, and therefore the sealing effect is more stable; due to the fact that the friction grooves capable of increasing the friction between the slip ring and the square sealing ring are formed in the outer circumferential surface of the slip ring, relative rotating movement of the slip ring and the square sealing ring is avoided; furthermore, due to the fact that the slip ring is made of self-lubricating and highly wear-resistant engineering plastic and the oil storage groove are formed in the inner circle of the slip ring, the lubricating effect is good, friction between the slip ring and a rotary shaft can be reduced, and then friction loss amount is reduced, the phenomenon that excessive heat is generated due to friction is avoided, the service life of the slip ring is prolonged, and break-out torque is reduced.
Description
Technical field
The utility model is a kind of rotating seal, and a kind of gas circuit rotating seal particularly belongs to the renovation technique of rotating seal.
Background technique
Existing rotary seal is widely used in the center-rotary joint of engineering machinery, during work, requires sealing reliable, and surface friction drag is little, the long lifetime.And traditional gas circuit rotary seal adopts the combination seal form of O shape circle 1.1 and PTFE slip ring 1.2, as shown in Figure 1, there is the problem of following several respects in actual applications in this structure: 1) running shaft band dynamic seal slip ring rotates together with O shape circle, causes the O-Ring Fast Wearing; 2) not lubricated, starting torque is large; 3) slip ring rapid wear, cause seal life not long; 4) sealing effect is unstable.So that be difficult to meet user's the requirement that is provided with.
The model utility content
The purpose of this utility model is to consider the problems referred to above and is provided a kind of working life that can effectively extend Sealing, and moment of torsion is little, the rotating seal that sealability is stable.The utility model is reasonable in design, convenient and practical.
The technical solution of the utility model is: rotating seal of the present utility model, include square seal ring, slip ring, and square seal ring is installed on the periphery of slip ring.
The periphery of above-mentioned slip ring is provided with some roads frictional groove of the friction that can increase between slip ring and square seal ring.
The inner headed face of above-mentioned slip ring has oil storage tank.
Above-mentioned slip ring is the selflubricatingpiston slip ring.
The utility model is due to the sealing configuration that adopts square seal ring and slip ring combination, and the Sealing Stress of square seal ring is comparatively uniform, and sealing effect is more stable.In addition, the cylindrical of slip ring has frictional groove, increases the friction of slip ring and square seal ring, guarantees that slip ring and square seal ring do not produce relative rotary motion; In addition, slip ring adopts the engineering plastics of self-lubricating high-wear-proof, and the slip ring inner headed face has oil storage tank, lubrication circumstances is good, can reduce the frictional force of slip ring and running shaft, thereby reduces abrasion loss, stop to produce because of friction the phenomenon of too much heat, improve the working life of slip ring, and reduce starting torque; The utility model is that a kind of design is ingenious, function admirable, convenient and practical rotating seal.
The accompanying drawing explanation
The structure diagram that Fig. 1 is traditional design;
Fig. 2 is structure diagram of the present utility model.
Embodiment
Embodiment:
As shown in Figure 2, rotating seal of the present utility model, include square seal ring 1, slip ring 2 to structural representation of the present utility model, and square seal ring 1 is installed on the periphery of slip ring 2.
In addition, the periphery of above-mentioned slip ring 2 is provided with some roads frictional groove 21 of the friction that can increase between slip ring and square seal ring.In the present embodiment, the periphery of above-mentioned slip ring 2 is provided with 3 road frictional grooves 21 of the friction that can increase between slip ring and square seal ring.
In addition, the inner headed face of above-mentioned slip ring 2 has oil storage tank 22.
Above-mentioned slip ring 2 is the selflubricatingpiston slip ring.In the present embodiment, slip ring 2 is self-lubricating high-wear-proof engineering plastics turning moulding, and square seal ring 1 use high-performance nitrile rubber sulfuration forms.
The seal form that the utility model adopts square seal ring 1 and slip ring 2 to combine.The comparatively uniform Sealing Stress of square seal ring 1 energy force of labor, used sealing effect more stable; Three frictional grooves 21 of slip ring 2 external diameters guarantee that in use slip ring 2 does not produce relative rotary motion with square seal ring 1; Have the oil storage tank 22 that volume is larger in the middle of slip ring 2 internal diameters, increased lubricating between slip ring 2 and running shaft, reduce friction, stop to produce because of friction the phenomenon of too much heat, improve the working life of slip ring 2.
Claims (5)
1. a rotating seal, is characterized in that including square seal ring (1), slip ring (2), and square seal ring (1) is installed on the periphery of slip ring (2).
2. rotating seal according to claim 1, is characterized in that the periphery of above-mentioned slip ring (2) is provided with some roads frictional grooves (21) of the friction that can increase between slip ring and square seal ring.
