Abstract
The invention belongs to the technical field of carrier rollers and aims at solving the problem that a carrier roller bearing is poor in sealing and waterproof performance so that the service life of a carrier roller is shortened, normal operation of a belt conveyer is influenced and huge loss on national economy is caused, and providing a lip seal waterproof structure carrier roller. The lip seal waterproof structure carrier roller comprises a carrier roller shaft, a carrier roller body, a bearing seat, an inner seal of the bearing seat, the carrier roller bearing, a lip seal, an O-shaped spring and a mirror face abrasion-resisting sleeve, wherein the inner hole face of the mirror face abrasion-resisting sleeve is provided with an O-shaped sealing ring, the left side of the mirror face abrasion-resisting sleeve is provided with an elastic retainer ring for the shaft, and the left side of the elastic retainer ring for the shaft is provided with an irony cover. The O-shaped sealing ring blocks water between the mirror face abrasion-resisting sleeve and the carrier roller shaft. The lip seal and the O-shaped spring on a right lip prevent the water between the lip seal and the mirror face abrasion-resisting sleeve from flowing into the bearing. The irony cover and the external cylindrical face of the lip seal are in interference fit with the inner hole face of the bearing seat so that the water is prevented from flowing into the bearing from the interference fit position. The lip seal and the mirror face abrasion-resisting sleeve are in contact and perform relative motions, the friction resistance is small, and contradiction between water proofing and resistance increase is overcome.
Description
Technical field
The invention belongs to Idler Technology field, be specifically related to the anti-water inlet structure carrying roller of a kind of lip seal.
Background technology
Carrying roller is the parts of bearing load on belt conveyer and other conveying machinery, and quantity is more, and its quality has influence on host machine integral parameter and the quality of belt conveyer.At present, the sealing means of Idler bearing has the sealing of 7 covers of DT II type, labyrinth type sealing etc., and the problem of existence is that anti-water inlet 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, has seriously affected the service life of carrying roller, be reduced to below 5% of design life service life, cause a large amount of carrying rollers to damage, affected the normal operation of belt conveyer, to national economy, brought huge loss.
Summary of the invention
The present invention is not enough in order to solve the anti-water inlet performance of current roller bearing sealing, causes carrying roller to reduce service life, has affected belt conveyer normal operation, to national economy, brings massive losses, provides a kind of lip seal anti-water inlet structure carrying roller.
The present invention is realized by following technical scheme: the anti-water inlet structure carrying roller of a kind of lip seal, comprise install carrying roller roll body roller carrier shaft, install the bearing assembly in bearing seat, 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 is installed 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 is offered 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, between iron covering and minute surface wear-resistant sleeve, install circlip for shaft.
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, by the trickle blocking-up of roller carrier shaft outside, between minute surface wear-resistant sleeve and roller carrier shaft, be to closely cooperate completely, there is no relative motion between the two; Between minute surface wear-resistant sleeve and lip seal, relatively rotate, 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, realization stops 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 minute surface 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 that water from entering.More than telling about is the structure of anti-water inlet structure carrying roller one side of lip seal, 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 been blocked water completely and entered between minute surface wear-resistant sleeve and roller carrier shaft; Between lip seal and minute surface wear-resistant sleeve, relatively rotate, left lip is realized and is stopped dust and water, right lip is realized block water, right lip outside is provided with O type spring, right lip is closely pressed on the cylindrical minute surface of minute surface wear-resistant sleeve, has blocked water completely and enter 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 the external cylindrical surface of iron covering and lip seal and the inner hole surface of bearing seat.Outside realizing aforementioned waterproof action, due to adopted lip seal to be and minute surface wear-resistant sleeve between relatively rotate, 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 that has reasonably solved waterproof and brought resistance to increase.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-roller carrier shaft; 2-circlip for shaft; 3-iron covering; 4-minute surface wear-resistant sleeve; 5-O RunddichtringO; 6-O type spring; 7-lip seal; 8-Idler bearing; Sealing in 9-; 10-bearing seat; 11-carrying roller roll body.
The specific embodiment
The anti-water inlet structure carrying roller of a kind of lip seal, comprise install carrying roller roll body 11 roller carrier shaft 1, install the bearing assembly in bearing seat 10, bearing assembly in described bearing seat 10 is provided with interior sealing 9, Idler bearing 8, lip seal 7, O type spring 6, minute surface wear-resistant sleeve 4, the inner hole surface of minute surface wear-resistant sleeve 4 is installed O RunddichtringO 5, circlip for shaft 2 is installed on minute surface wear-resistant sleeve 4 left sides, and iron covering 3 is installed on circlip for shaft 2 left sides.
