Abstract
The invention provides a rolling bearing which comprises an outer ring, an inner ring, a rolling body and a retainer, wherein the rolling body is positioned between the raceway of the inner ring and the raceway of the outer ring, and the rolling body is uniformly separated by the retainer in the raceways along the circumferential direction. The rolling bearing is characterized in that a sealing device is arranged in a sealing groove of a bearing ring, and the sealing device is arranged outside the retainer. The sealing device is made from polyfluortetraethylene, and the minimum clearance formed between the sealing device and the inner ring as well as the outer ring is 0.001 millimeter. In the invention, the polyfluortetraethylene material is used for making a sealing element for replacing a metal stamping type dustproof cover and a rubber sealing ring, thereby avoiding the influence on the circularity, ellipticity and verticality of the outer ring of the rolling bearing (especially a thin-wall bearing) when the stamping type dustproof cover is assembled on the bearing, improving the sealing effect and dustproof effect, and simultaneously improving the compatibility of the sealing element and a lubricating agent.
Description
Technical field
The present invention relates to a kind of bearing, particularly the technical field of sealing technology of rolling bearing.
Background technique
Rolling bearing generally adopts metal stamping formula dust cover, rubber seal to seal.The rolling bearing that adopts metal stamping formula dust cover to seal, cause that easily circularity, ovality and the perpendicularity of housing washer are overproof when rolling bearing assembles the punching press dust cover on the one hand, then cause bearing degradation or scrap, especially bigger for the thin-wall bearing influence; The metal dust cover contacts with seal groove when avoiding bearing operation on the other hand, and seal clearance is selected bigger, thereby causes the sealing and dustproof weak effect.Adopt the rolling bearing of rubber material as Sealing, rubber seal and bearing internal lubricant compatibility are relatively poor.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of easy for installation, seal clearance little and with the compatible good rolling bearing of oiling agent.
Rolling bearing of the present invention comprises outer ring, inner ring, rolling element, retainer; Rolling element is between the raceway of inner ring and outer ring; Retainer is along the circumferential direction evenly separated rolling element in raceway; Be provided with seal arrangement in the seal groove of bearing ring, described seal arrangement is located at the outside of described retainer, and the material of described seal arrangement is a teflon.
As a kind of optimal way of the present invention,, make the single face stuffing box bearing at the one-sided seal arrangement that is provided with of rolling bearing; Perhaps the bilateral at rolling bearing is provided with seal arrangement, makes the dual face seals bearing.
As a kind of optimal way of the present invention, described rolling element is ball or cylindrical roller or tapered roller or needle roller or spherical roller or spiral roller, and corresponding bearing is ball bearing or roller bearing or tapered roller bearing or needle bearing or spheric roller bearing or spiral roller bearing.
As a kind of optimal way of the present invention, smallest radial seal clearance between described seal arrangement and the inner ring seal groove and minimum axial direction seal clearance minimum are 0.001 millimeter.
Rolling bearing of the present invention, adopt polytetrafluoroethylmaterial material to do Sealing and replace metal stamping formula dust cover and rubber seal, to the influence of outer ring circularity, ovality and the perpendicularity of rolling bearing especially thin-wall bearing, improved the compatibility of sealing and dustproof effect and Sealing and oiling agent simultaneously when having avoided bearing assembling punching press dust cover.

Embodiment
Below in conjunction with accompanying drawing rolling bearing of the present invention is described in further detail.
As shown in Figure 1, rolling bearing of the present invention comprises: outer ring 1, inner ring 2, rolling element 3, retainer 4; Rolling element 3 is between the raceway of inner ring 2 and outer ring 1; Retainer 4 is along the circumferential direction evenly separated rolling element 3 in raceway; Be provided with seal arrangement 5 in the seal groove of bearing ring, seal arrangement 5 is located at the outside of retainer 4, and the material of seal arrangement 5 is a teflon, and smallest radial seal clearance and minimum axial direction seal clearance minimum between itself and the inner ring seal groove are 0.001 millimeter.
During installation, enchashment row machining finishes, etc. bearing outer ring 1, inner ring 2, rolling element 3 and retainer 4 to be assembled, take up allotment of labor's skill according to normal axis and finish apolegamy and riveted and cleaning-drying; Then, to the inner oiling agent 6 that adds of rolling bearing; Then polytetrafluoroethylmaterial material seal arrangement 5 is pressed in the seal groove of housing washer 1 and inner ring 2; Be coated with rust preventive oil, packing at last.
Claims (4)
