Abstract
The utility model discloses a low-temperature resistant sealing ring which is applied to a double-row full-complement cylindrical roller bearing. The low-temperature resistant sealing ring comprises a sealing ring and a support framework, wherein the sealing ring is a rubber sealing ring, the support framework is a steel framework, the sealing ring and the support framework are combined into a whole in an injection pouring mode, the sealing ring and the support framework are the same in inner diameter, and the outer diameter of the support framework is larger than that of the sealing ring. By means of the method, the low-temperature resistant sealing ring is capable of meeting the low-temperature resistant sealing performance, has double-sealing performance to the sealing ring, and improves the overall strength.
Description
Technical field
The utility model relates to the bearing seal technical field, particularly relates 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 to 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, mainly all be to process with engineering plastics or polyurethane material, and the cryogenic property of this bi-material is not fine, will hardening be become fragile after-78 degree cryogenic freezings by its seal ring of making, even be full of cracks occurs, in this case, adopt low-temperature mounting such as the client, seal ring will lose its original performance so, can not play seal action.This class seal ring can't satisfy the demand that the client installs bearing low-temperature.
The model utility content
The technical problem that the utility model 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, improves simultaneously the bulk strength of seal ring.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of low temperature resistant seal ring is provided, be used for double-row full-complement cylinder roller bearing, comprise: seal ring and support frame, described seal ring is rubber seal, described support frame is Steel Skeleton, 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 equates that the outside dimension of described support frame is greater than the outside dimension of described seal ring.
In preferred embodiment of the utility model, the material of described seal ring is silicone rubber.
In preferred embodiment of the utility model, the material of described support frame is stainless steel.
In preferred embodiment of the utility model, described stainless steel is 1Cr18Ni9Ti.
In preferred embodiment of the utility model, the operating temperature range of described low temperature resistant seal ring is-78 ℃ to+250 ℃.
The beneficial effects of the utility model are: the utility model has 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, 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 utility model;
The mark of each parts is as follows in the accompanying drawing: 1, support frame, 2, seal ring.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, the utility model is embodiment comprise:
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, described seal ring 2 is rubber seal, described support frame 1 is Steel Skeleton, described seal ring 2 and support frame 1 mode by injection moulding fastens in aggregates, and the internal diameter size of described seal ring 2 and described support frame 1 equates that the outside dimension of described support frame 1 is greater than the outside dimension of described 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 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 excellent performances such as heat resistance, winter hardiness, dielectricity, anti-ozone and anti-atmospheric aging, can be-60 ℃ to+250 ℃ lower long-term uses, the seal ring smooth surface of being made by silicone rubber, incompressible permanent deformation performance is significantly improved, at high temperature have better supportive, and technology capability is better, easily processing.
The material of described support frame is 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-medium corrosion.
Described stainless steel is preferably 1Cr18Ni9Ti.
The operating temperature range of described low temperature resistant seal ring is-78 ℃ to+250 ℃, can fully satisfy the required cryogenic property of client.
The utility model has 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, 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 only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; 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 utility model.
