Abstract
The utility model discloses a sealing device of a roller bearing and a sealing structure with the device. The sealing device comprises a sealing ring, the sealing ring comprises a tapered cylinder-shaped clamp ring and a peripheral frame, the tapered cylinder-shaped clamp ring is arranged at the inner part of the sealing ring and is used for matching with a shaft, and the large-opening end of the tapered cylinder-shaped clamp ring is fixedly connected with the peripheral frame by a ring-shaped end surface. As the tapered cylinder-shaped clamp ring at the inner ring of the sealing ring is elastic and is matched with the shaft in an interference manner, the internal and external seepage of a liquid bearing can be effectively prevented. Moreover, the sealing device adopts the dual sealing sheet structure and two sealing sheets are symmetrically arranged; as the small opening of the clamp ring on the sealing sheet at the inner side is in the direction of the inner side, the outward leakage of lubricating agent in the bearing can be prevented; as the small opening of the clamp ring on the sealing ring at the outer side is in the direction of the outer side, the invasion of polluted liquid at the outer side of a bearing end cover can be prevented; therefore, the bearing cannot be damaged due to the invasion of external liquid pollutants or the outward leakage of the internal lubricating agent, thus prolonging the service life of the roller bearing.
Description
Technical field
The utility model relates to a kind of seal arrangement of roller bearings, especially a kind of seal arrangement of belt hauler stern barrel bearing.Simultaneously, the utility model also relates to a kind of sealing configuration with sealing device.
Background technique
The seal arrangement of currently used hauler stern barrel bearing is a felt seal labyrinth seal structure; this device comprises roller bearings and bearing (ball) cover; in bearing (ball) cover, be installed with a seal ring; the rotatingshaft interference fit of sealing circle and cylinder is provided with a protective cover of fixing with the rotatingshaft of cylinder in the side of bearing (ball) cover.This device can prevent dust intrusion bearing inside, still, and along with the continuous expansion of roller bearings Applicable scope, some problems occurred: this device can not prevent the intrusion of liquid to bearing, and simultaneously, the oiling agent of bearing inside leaks easily, cause damage of bearings easily, lower the life-span for the treatment of as of bearing.
The model utility content
The technical problem that the utility model solved provides a kind of seal arrangement of roller bearings, invades bearing to prevent liquid pollutant, prevents that bearing lubricant from leaking.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: a kind of roller bearings seal arrangement, comprise seal ring, described seal ring comprises inner being used for and spool the cone barrel type collar and the periphery skeleton that cooperate, and the big opening end of cone barrel type collar and periphery skeleton are connected by annular end face.
Described periphery skeleton is annular claw.
Described annular end face, periphery skeleton and cone barrel type collar excessively are the one metal frame.
Another technical problem that the utility model solved provides a kind of sealing configuration with roller bearings seal arrangement, invades bearing to prevent liquid pollutant, prevents that bearing lubricant from leaking.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: a kind of sealing configuration with roller bearings seal arrangement, comprise axle and bearing (ball) cover, be provided with axis hole in the bearing (ball) cover, described axis hole inboard is provided with installation cavity, described at least two seal arrangements are assemblied in the installation cavity by its peripheral periphery skeleton interference, and the interference of described axle is assemblied in the osculum of seal arrangement cone barrel type collar.
Described two seal arrangements are symmetrical arranged, the osculum end of described cone barrel type collar towards direction opposite.
The beneficial effects of the utility model are: because the cone barrel type collar of seal ring inner ring has certain elasticity, with the axle interference fit, can effectively prevent the seepage flow of liquid-bearing inside and outside.
In addition, because the double-sealing chip architecture that the utility model adopts, two diaphragm seals are symmetrical arranged, the little opening direction of collar on the inboard diaphragm seal is towards the inboard, prevent that the oiling agent in the bearing from leaking, the little opening direction of the collar on the seal ring in the outside prevents the contaminated liquid invasion in the bearing (ball) cover outside toward the outer side, make bearing be difficult for damaging, improved the working life of roller bearings because of the intrusion or the leaking of internal lubricant of outside liquid pollutant.
