Abstract
The invention belongs to Idler Technology field, not enough for solving roller bearing sealing water-inlet-proof performance, carrying roller reduces service life, affects belt conveyer normal operation, brings massive losses to national economy, provide a kind of Lip seal waterproof structure carrier roller.Comprise roller carrier shaft, carrying roller roll body, bearing seat and interior interior sealing, Idler bearing, lip seal, O type spring, minute surface wear-resistant sleeve, the inner hole surface of minute surface wear-resistant sleeve establishes O RunddichtringO, circlip for shaft is established on the minute surface wear-resistant sleeve left side, and iron covering is established on the circlip for shaft left side.O RunddichtringO blocks water and enters between minute surface wear-resistant sleeve and roller carrier shaft; O type spring on lip seal and right lip blocks water and enters bearing between lip seal and minute surface wear-resistant sleeve; The external cylindrical surface of iron covering and lip seal all with inner hole of bearing seat face interference fit, blocked water and entered bearing from Fit; Lip seal contacts with minute surface wear-resistant sleeve and relative motion, and friction drag is less, solves the contradiction of waterproof and resistance increase.
Description
Technical field
The invention belongs to Idler Technology field, be specifically related to a kind of Lip seal waterproof structure carrier roller.
Background technology
Carrying roller is the parts of bearing load on belt conveyer and other conveying machinery, and quantity is more, its quality, has influence on host machine integral parameter and the quality of belt conveyer.At present, the sealing means of Idler bearing has 7, DT II type to overlap sealing, labyrinth seal etc., and Problems existing is, water-inlet-proof performance is inadequate, spy is standby is in the serious occasion of trickle, the carrying roller of this seal form, due to bearing water inlet, seriously have impact on the service life of carrying roller, be reduced to less than 5% of design life service life, cause a large amount of carrying roller to damage, have impact on the normal operation of belt conveyer, bring huge loss to national economy.
Summary of the invention
The present invention is not enough in order to solve current roller bearing sealing water-inlet-proof performance, causes carrying roller to reduce service life, have impact on belt conveyer normal operation, bring massive losses to national economy, provide a kind of Lip seal waterproof structure carrier roller.
The present invention is realized by following technical scheme: a kind of Lip seal waterproof structure carrier roller, comprise roller carrier shaft, the bearing assembly installed in bearing seat that carrying roller roll body is installed, bearing assembly in described bearing seat is provided with interior sealing, Idler bearing, lip seal, O type spring, minute surface wear-resistant sleeve, the inner hole surface of minute surface wear-resistant sleeve installs O RunddichtringO, circlip for shaft is installed on the minute surface wear-resistant sleeve left side, and iron covering is installed on the circlip for shaft left side.
Described roller carrier shaft and minute surface wear-resistant sleeve inner hole surface are combined closely, and described minute surface wear-resistant sleeve inner hole surface offers groove, installs 0 RunddichtringO in groove; Minute surface wear-resistant sleeve outside cylinder minute surface arranges lip seal, the left lip of described lip seal contacts with the outside cylinder minute surface of minute surface wear-resistant sleeve with right lip, right lip outside is provided with O type spring, the external cylindrical surface of iron covering and lip seal all with inner hole of bearing seat face interference fit, install circlip for shaft between iron covering and minute surface wear-resistant sleeve.
The inner hole surface of minute surface wear-resistant sleeve is provided with the groove of mounting O-shaped seal ring, O RunddichtringO is in the groove of minute surface wear-resistant sleeve inner hole surface and between roller carrier shaft, completely the trickle of roller carrier shaft outside is blocked, be closely cooperate between minute surface wear-resistant sleeve and roller carrier shaft, there is no relative motion between the two; Relatively rotate between minute surface wear-resistant sleeve and lip seal, the left lip of lip seal contacts with the outside cylinder minute surface of minute surface wear-resistant sleeve with right lip, left lip is first sealing, realize stopping dust and water, right lip is second sealing, realizes the effect of block water, because right lip outside is also provided with O type spring, right lip is closely pressed on the cylindrical mirror of minute surface wear-resistant sleeve, blocks water completely and enter bearing; The external cylindrical surface of iron covering and lip seal all with the inner hole surface interference fit of bearing seat, prevented water from entering.More than telling about is the structure of Lip seal waterproof structure carrier roller side, and opposite side is identical with it.
Compared with prior art, feature of the present invention is: O RunddichtringO, in the groove of minute surface wear-resistant sleeve inner hole surface and between roller carrier shaft, has blocked water completely and entered between minute surface wear-resistant sleeve and roller carrier shaft; Relatively rotate between lip seal and minute surface wear-resistant sleeve, left lip realizes stopping dust and water, right lip realizes block water, right lip outside is provided with O type spring, right lip is closely pressed on the cylindrical mirror of minute surface wear-resistant sleeve, has blocked water completely and entered bearing between lip seal and minute surface wear-resistant sleeve outside cylinder minute surface; The external cylindrical surface of iron covering and lip seal all with the inner hole surface interference fit of bearing seat, blocked water completely and entered from iron covering and the external cylindrical surface of lip seal and the inner hole surface of bearing seat.Realizing outside aforementioned waterproof action, relatively rotate between minute surface wear-resistant sleeve owing to have employed lip seal, the technology that the left lip of lip seal contacts with the outside cylinder minute surface of minute surface wear-resistant sleeve with right lip, make contact frictional resistance less, the contradiction reasonably solving waterproof He bring resistance to increase.
