Description

A kind of compound seal idler structure of travelling apron
Technical field
The utility model relates to a kind of travelling apron, relates in particular to a kind of compound seal idler structure of travelling apron.
Background technology
Along with the continuous development and the raising of modern mechanical degree, the use of travelling apron more and more widely and is just developing towards long distance, large conveying quantity, high-speed direction, with the needs of the modern production that satisfies high-yield and high-efficiency.Carrying roller is as a minimum unit of travelling apron, and its quality, design form are directly connected to the running performance of conveyer.But present employed conveyer carrying roller, as the employed conveyer of coal mining industry, the seal style of its carrying roller all is only to adopt axial labyrinth packing basically, this seal style sealing property is not good, water resistance is poor, often because the erosion of coal water, muddy water causes the damage of carrying roller.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and the compound seal idler structure of the good travelling apron of a kind of sealing property is provided, and it can prevent muddy water, foreign material intrusion roller carrier shaft bearing inside by actv..
To achieve these goals, the utility model is by the following technical solutions:
A kind of compound seal idler structure of travelling apron, comprise body and axle, the equal installation shaft bearing in body two ends, bearing is installed in the bearing seat, and bearing one side is resisted against the bearing seat bottom, and opposite side is against labyrinth seal, the shaft block ring that is provided with on the axle compresses labyrinth seal, the open end of described bearing seat is a bowl type, and the bowl RunddichtringO that cooperates with described bearing seat open end of installation, packing seal is installed between bottom described bearing and the bearing seat.
In the technique scheme, enter bearing seat in order more effectively to prevent foreign material such as muddy water, described bowl RunddichtringO is compressed by Sealing shield ring, and Sealing shield ring and bowl RunddichtringO cooperate the axial labyrinth packing of formation.
Owing to adopt technique scheme, the utility model obtains following beneficial effect:
1, the open end of the utility model bearing seat be designed to bowl type and installed one fitted shaft bearing open end the bowl RunddichtringO; centnifugal force in the time of can relying on the carrying roller rotation throws away water or coal slime etc.; make it can not enter annular seal space and labyrinth packing inside; strengthen sealing effectiveness, effectively protected the bearing normal operation.
2, add packing seal between bearing and the bearing seat bottom, packing seal can stop the oil in the bearing excessive with the axle junction by bearing seat effectively, guarantee that bearing has enough oil to make it be in lubricating status, reduced the wearing and tearing of bearing, prolonged the service life of bearing.
3, packing seal can also stop by the junction by bearing seat and axle such as carrying roller in-to-in impurity, empty such as iron rust, dust etc. and enters bearing seat inside, guarantees the normal operation of bearing, more helps prolonging the service life of bearing.
Description of drawings
Fig. 1 is the utility model carrying roller scheme drawing.
Fig. 2 is an A place enlarged drawing among Fig. 1.
The specific embodiment
The carrying roller that goes out illustrated in figures 1 and 2, carrying roller body 1 is a pipe, inside is provided with axle 4, the equal installation shaft bearing 8 in carrying roller body 1 both ends, the bearing seat 8 inner bearings 6 of installing, shaft block ring 3 is pressed on labyrinth seal 7 on the bearing 6, can effectively prevent bearing 6 end float misalignments like this.The open end of bearing seat 8 is a bowl type, and the bowl RunddichtringO 2 that cooperates with bearing seat 8 open ends of installation, and bowl RunddichtringO 2 is pressed on the open end of bearing seat 8 by Sealing shield ring 21.
When carrying roller rotates, be thrown out of under action of centrifugal force attached to meetings such as the water of body 1 end face or muddy water, make it can not enter no fat chamber 9, strengthened sealing effectiveness, effectively protect bearing 7 normal operations.As preferably, Sealing shield ring 21 axial compression bowl RunddichtringOs 2 are at bearing seat 8 open ends, the clearance control of bowl RunddichtringO 2 and bearing seat 8 open ends in as far as possible little scope, prevent that muddy water etc. is penetrated in the no fat chamber 9 by the gap fast, Sealing shield ring 21 and bowl RunddichtringO 2 cooperate the axial labyrinth packing of formation, like this, just prevent effectively that foreign material such as muddy water from entering the inside of bearing seat 8 by the gap of axle 4 and bowl RunddichtringO 2, guarantees that carrying roller normally moves.
Bearing 6 is installed in bearing seat 8 inside, one or several packing seals 5 are installed between bearing seat 8 bottoms and bearing 6, like this, grease in the bearing 6 is difficult to be leaked to body 1 inside by bearing seat 8 bottoms, guarantee that bearing 6 has enough oil to make it be in lubricating status, reduce the wearing and tearing of bearing 6, can prevent that iron rust, the dust and other impurities in body 1 cylindrical shell from invading bearing 6 inside simultaneously, prolonged the service life of bearing 6.
Leave no fat chamber 9 between bowl RunddichtringO 2 and the labyrinth seal 7, like this, the pollution fat at bowl RunddichtringO 2 places can easily not contact with the clean fat at labyrinth seal 7 and bearing 6 places.Effectively preventing to pollute fat and clean fat mixes.And then improved body 1 in-to-in sealing effectiveness, reduced the rate of breakdown of travelling apron.
