Abstract
The invention discloses a low-temperature-resisting sealing ring which is used for double rows of full-capacity cylindrical roller bearings. The low-temperature-resisting sealing ring comprises a sealing ring and a supporting framework; the sealing ring is a rubber sealing ring, and the supporting framework is a steel framework; the sealing ring and the supporting framework are buckled into a whole body through an injection molding manner; the sizes of the inner diameters of the sealing ring and the supporting framework are the same; and the size of the outer diameter of the supporting framework is greater than the size of the outer diameter of the sealing ring. With the adoption of the manner, the low-temperature-resisting performance of the sealing ring can be met, and the low-temperature-resisting sealing ring has double sealing performances; and meanwhile, the whole strength of the sealing ring is improved.
Description
Technical field
The present invention relates to bearing seal technical field, particularly relate to a kind of low temperature resistant seal ring.
Background technique
The double-row full-complement cylinder roller bearing of sealing configuration, mainly applies in the pulley of jack machinism.In the process of pulley manufacturing industry fast development, due to the special requirement of installing, bearing to need under-78 degree freezing 3 hours, then is installed in pulley.
At present, the seal ring that bearing industry is joined for pulley special bearing (double-row full-complement cylinder roller bearing), main is all process with engineering plastics or polyurethane material, and the cryogenic property of this bi-material is not fine, the seal ring be made up of it will hardeningly become fragile after-78 degree cryogenic freezings, even occurs be full of cracks, in this case, as client adopts low-temperature mounting, so seal ring will lose its original performance, can not play seal action.This kind of seal ring cannot meet the demand that client installs bearing low-temperature.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of low temperature resistant seal ring, can meet the resistance to low temperature of seal ring, makes it possess double seal, improves the bulk strength of seal ring simultaneously.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of low temperature resistant seal ring, for double-row full-complement cylinder roller bearing, comprise: seal ring and support frame, described seal ring is rubber seal, and described support frame is Steel Skeleton, and described seal ring and support frame fasten in aggregates by the mode of injection moulding, and the internal diameter size of described seal ring and described support frame is equal, the outside dimension of described support frame is greater than the outside dimension of described seal ring.
In a preferred embodiment of the present invention, the material of described seal ring is silicone rubber.
In a preferred embodiment of the present invention, the material of described support frame is stainless steel.
In a preferred embodiment of the present invention, described stainless steel is 1Cr18Ni9Ti.
In a preferred embodiment of the present invention, the operating temperature range of described low temperature resistant seal ring is-78 DEG C to+250 DEG C.
The invention has the beneficial effects as follows: present invention is disclosed a kind of low temperature resistant seal ring, original polyurethane sealing ring is replaced to the seal ring of new structure, adopt silicone rubber O-ring and support frame injection molded, the resistance to low temperature of seal ring can be met, and make it possess double seal performance; Owing to having set up stainless steel support frame, the bulk strength of seal ring is improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention's low temperature resistant seal ring one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, support frame, and 2, seal ring.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of low temperature resistant seal ring, for double-row full-complement cylinder roller bearing, comprise: seal ring 2 and support frame 1, described seal ring 2 is rubber seal, described support frame 1 is Steel Skeleton, described seal ring 2 and support frame 1 fasten in aggregates by the mode of injection moulding, and the internal diameter size of described seal ring 2 and described support frame 1 is equal, and the outside dimension of described support frame 1 is greater than the outside dimension of described seal ring 2.After making it be pressed into the seal groove of bearing enclose, seal ring 2 all adopts interference fit with the inside and outside circle of bearing, and mainly rely on support frame 1 with coordinating of bearing inner race, support frame 1 and bearing inner race adopt interference fit, adopt Spielpassung with bearing outer ring, make it reach the effect of double seal.
The material of described seal ring is silicone rubber, it has the performances such as excellent heat resistance, winter hardiness, dielectricity, resistance to ozone and resistance to atmospheric aging, can at-60 DEG C to+250 DEG C Long-Time Service, the seal ring smooth surface be made up of silicone rubber, incompressible permanent deformation performance can be made to be significantly improved, at high temperature there is preferably supportive, and technology capability is better, easily processes.
The material of described support frame is stainless steel, has good plasticity, toughness, weldability and corrosion resisting property, and in oxidability and Reductant, corrosion resistance is all better, and its good combination property, can resistant to many dielectric corrosion.
Described stainless steel is preferably 1Cr18Ni9Ti.
The operating temperature range of described low temperature resistant seal ring is-78 DEG C to+250 DEG C, fully can meet the required cryogenic property of client.
Present invention is disclosed a kind of low temperature resistant seal ring, original polyurethane sealing ring is replaced to the seal ring of new structure, adopt silicone rubber O-ring and support frame injection molded, the resistance to low temperature of seal ring can be met, and make it possess double seal performance, owing to having set up stainless steel support frame, the bulk strength of seal ring is improved.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
Claims (2)
