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 the 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, because the special requirement of installing, bearing need be under-78 degree freezing 3 hours, are installed in the pulley again.
At present, bearing industry is the seal ring that pulley special bearing (double-row full-complement cylinder roller bearing) is joined, and mainly all is to process with engineering plastics or polyurethane material; And the cryogenic property of these two kinds of materials is not fine, will hardening be become fragile after-78 degree cryogenic freezings by its seal ring of processing, even be full of cracks occurs; In this case; Adopt low-temperature mounting like the client, seal ring will lose its original performance so, can not play seal action.This type seal ring can't satisfy the demand that the client installs bearing low-temperature.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of low temperature resistant seal ring, can satisfy the resistance to low temperature of seal ring, makes it possess double seal property, 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: a kind of low temperature resistant seal ring is provided, is used for double-row full-complement cylinder roller bearing; Comprise: seal ring and support frame; Said seal ring is a rubber seal, and said support frame is a Steel Skeleton, and said seal ring and support frame fasten in aggregates through injection molding way; And the internal diameter size of said seal ring and said support frame equates that the outside dimension of said support frame is greater than the outside dimension of said seal ring.
In preferred embodiment of the present invention, the material of said seal ring is a silicone rubber.
In preferred embodiment of the present invention, the material of said support frame is a stainless steel.
In preferred embodiment of the present invention, said stainless steel is 1Cr18Ni9Ti.
In preferred embodiment of the present invention, the operating temperature range of said low temperature resistant seal ring is-78 ℃ to+250 ℃.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of low temperature resistant seal ring; Original polyurethane seal ring is replaced to the seal ring of new structure; Adopt silicone rubber O-ring and support frame injection molded, can satisfy the resistance to low temperature of seal ring, and make it possess the double seal performance; Owing to set up the stainless steel support frame, the bulk strength of seal ring be improved.
Description of drawings
Fig. 1 is the structural representation of low temperature resistant seal ring one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, support frame, 2, seal ring.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of low temperature resistant seal ring; Be used for double-row full-complement cylinder roller bearing, comprise: seal ring 2 and support frame 1, said seal ring 2 is a rubber seal; Said support frame 1 is a Steel Skeleton; Said seal ring 2 is in aggregates through the injection molding way fastening with support frame 1, and the internal diameter size of said seal ring 2 and said support frame 1 equates that the outside dimension of said support frame 1 is greater than the outside dimension of said seal ring 2.After making its seal groove that is pressed into bearing enclose; Seal ring 2 all adopts interference fit with the inside and outside circle of bearing; And with mainly rely on support frame 1 cooperating of bearing inner race; Support frame 1 adopts interference fit with bearing inner race, adopts Spielpassung with bearing outer ring, makes it reach the effect of double seal.
The material of said seal ring is a silicone rubber; It has excellent performances such as heat resistance, winter hardiness, dielectricity, anti-ozone and anti-atmospheric aging, can be-60 ℃ to+250 ℃ long-term down use, and the seal ring smooth surface of processing by silicone rubber; Can make incompressible permanent deformation performance obtain significant the improvement; At high temperature have preferable supportive, and technology capability is better, is prone to processing.
The material of said support frame is a stainless steel, has good plasticity, toughness, weldability and corrosion resisting property, and corrosion resistance is all better in oxidability and Reductant, and its good combination property can anti-multiple dielectric corrosion.
Said stainless steel is preferably 1Cr18Ni9Ti.
The operating temperature range of said low temperature resistant seal ring is-78 ℃ to+250 ℃, can fully satisfy the required cryogenic property of client.
The present invention has disclosed a kind of low temperature resistant seal ring; Original polyurethane seal ring is replaced to the seal ring of new structure; Adopt silicone rubber O-ring and support frame injection molded, can satisfy the resistance to low temperature of seal ring, and make it possess the double seal performance; Owing to set up the stainless steel support frame, the bulk strength of seal ring be improved.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
