Abstract
The invention discloses a seal assembly and a slewing bearing using the same. The seal assembly comprises a seal lip (12) and a dust retaining plate. A steel plate frame (6) is arranged in a connecting base (8) of the seal lip, and an oil lip (5) of the seal lip is hook-shaped. The dust retaining plate and the seal lip are arranged separately. The oil lip of the seal lip is hook-shaped, and accordingly lubricating oil can be prevented from leakage effectively. The dust retaining plate is arranged outside the seal lip, so that dust prevention can be achieved better, and the seal lip can be protected. The invention further discloses a slewing bearing using the seal assembly.
Description
?
Technical field
The present invention relates to technical field of bearings, be specifically related to the pivoting support of a kind of black box and use sealing assembly.
Background technique
Also dispose black box on the existing pivoting support, major part all is common lip seal, and sealing configuration is single, and this structure can not prevent effectively that lubricant grease from leaking outside, and dustproof weak effect, thereby influences pivoting support working life.
Summary of the invention
The invention technical problem to be solved provides the pivoting support black box of a kind of good sealing effect, long service life, and the invention also provides a kind of pivoting support that uses the sealing assembly.
A kind of black box comprises sealing lip and dust board, in the connection basis of said sealing lip steel plate frame is set, and the oily lip of sealing lip is set to hook type; Said dust board separates setting with sealing lip.
Further, said dust board is set to two.
Further, the outside, the connection basis of said sealing lip is provided with groove, in the said groove cranse is set.
A kind of pivoting support uses above-mentioned black box.
Further, said pivoting support inner ring external diameter is provided with annular shallow slot, and the corresponding end face with annular shallow slot in said pivoting support outer ring is provided with seal groove, and annular shallow slot cooperates with the basis that is connected of sealing lip, and the oily lip of sealing lip is set in the seal groove; The vertical dust board that is provided with on said pivoting support inner ring and the outer ring, the space environmental sealing lip that said dust board forms.
Because adopt technique scheme, the invention possesses following beneficial effect:
1, is provided with steel plate frame in the sealing lip connection basis, strengthened the sealing lip self rigidity.
2, sealing lip oil lip is set to crotch shape, can prevent effectively that lubricant grease from leaking outside.
3, sealing lip is provided with dust board outward, can better play dustproof effect, and the protection sealing lip.
Description of drawings
Fig. 1 is the structural representation of the black box of the invention;
Fig. 2 is a structural representation of using the pivoting support of the invention black box;
Among the figure: 1, outer ring; 2, inner ring; 3, dust board A; 4, dust board B; 5, oily lip; 6, steel plate frame; 7, cranse; 8, connect the basis; 9, groove; 10, annular shallow slot; 11, seal groove; 12, sealing lip.
Embodiment
In conjunction with Fig. 1, a kind of black box of present embodiment comprises sealing lip 12 and dust board A3, dust board B4, in the connection basis 8 of sealing lip steel plate frame 6 is set, so that strengthen the sealing lip self rigidity; The oily lip 5 of sealing lip is set to hook type, can more effectively prevent that lubricant grease from leaking outside; 8 outsides, connection basis of sealing lip are provided with groove 9, cranse 7 are set, so that sealing lip and associated components is fastening in the said groove.Dust board A3, dust board B4 separate setting with sealing lip.
In conjunction with Fig. 2; Use a kind of pivoting support of above-mentioned black box; On pivoting support inner ring 2 external diameters, be provided with annular shallow slot 10; Pivoting support outer ring 1 corresponding end face with annular shallow slot is provided with seal groove 11, and annular shallow slot 10 cooperates with the basis 8 that is connected of sealing lip, and the oily lip 5 of sealing lip is set in the seal groove 11; Vertical dust board A3 and the dust board B4 of being provided with on pivoting support inner ring and the outer ring, the space environmental sealing lip 12 that dust board A3 and dust board B4 form.
The disclosed black box of the invention can prevent better that lubricant grease from leaking outside, and dustproof effect has also improved a lot, and improve working life greatly.
