Abstract
A kind of single-bearing supporting carrier roller, it is made up of support shaft, bearing and roller circle, bearing inner race interference fit is arranged in support shaft, and roller circle interference fit is arranged on bearing outer ring；One bearing is only installed, and bearing both sides are separately installed with sealing device between described support shaft and roller circle；Described sealing device is labyrinth seal.Beneficial effect is：Simple in construction, width is small, is mountable to dead angle position and is supported the use with existing carrying roller, makes adhesive tape transitions smooth stable, eliminates the problem of abrasion that conveyer belt Dead Core Problems are brought scratches serious, service life reduction.
Description
Technical field
The utility model is specifically related to a kind of improved labyrinth seal carrying roller.
Background technology
With the development of ribbon conveyer, U-shaped ribbon conveyer and pipe conveyer, and in various special belt conveyors,
For the flatness of adhesive tape grooving, there is a higher requirement, three-roller type carrying roller groove forming character is very used by common belt conveyor
It is good to hold, but for U-shaped ribbon conveyer, pipe conveyer, and other special belt conveyors, because carrying roller is by more piece carrying roller
Combination is formed, and length is excessive between carrying roller, causes partial cross section dead angle occur, and adhesive tape transition is imperfect, so adhesive tape damage is tight
Weight, service life reduction.
The conveyer of above mentioned problem is presently, there are, space all very littles of dead angle position are, it is necessary to install a small-sized carrying roller
Can just overcome drawbacks described above, problem be the small-sized carrying roller of installation must be with other supporting carrying rollers of idler diameter identical, and show
Some carrying rollers, the minimum widith of its carrying roller composition structures shape can not meet use demand also beyond the width of dead-space volume.
The content of the invention
The purpose of this utility model is to solve U-shaped ribbon conveyer, pipe conveyer, and various special belt conveyors
Carrying roller supporting construction exist with belt contacts less than dead angle, the problem of causing adhesive tape damage serious, service life reduction, there is provided one
Kind build is narrow, can be installed on the carrying roller of dead angle position.
To achieve these goals, technical scheme is adopted between roller circle and roll shaft by carrying roller used by the utility model
Supported with single-bearing, play a part of fixed support strength using bearing outer ring and roller circle interface width, pacify in bearing double-side
Fill sealing device, it is preferably to use labyrinth seal, reduce carrying roller abrasion, roller circle width is finally shortened into only bearing width
Within 5 times.
The utility model single-bearing supporting carrier roller, it is made up of support shaft, bearing and roller circle, bearing inner race interference fit installation
In support shaft, roller circle interference fit is arranged on bearing outer ring；One axle is only installed between described support shaft and roller circle
Hold, and bearing both sides are separately installed with sealing device；Described sealing device is labyrinth seal.
Described bearing and roller circle are installed along support shaft center, and whole idler structure is along support shaft center axle pair
Claim.
Described sealing device includes sealing ring, cover lid and protective cover, is installed successively outward along position of bearings from interior.
Described labyrinth seal, sealing ring have sealing inner ring and sealed outer ring combination installation to form.
The beneficial effects of the utility model are：Simple in construction, width is small, is mountable to dead angle position and existing carrying roller
Support the use, make adhesive tape transitions smooth stable, eliminate the abrasion that conveyer belt Dead Core Problems are brought and scratch serious, life-span drop
The problem of low.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the utility model single-bearing supporting carrier roller；
In accompanying drawing：Support shaft 1；Bearing 2；Labyrinth interior sealing inner ring 3；Labyrinth external seal outer ring 4；Cover lid 5；Protective cover 6；Gear
Circle 7；Roller circle 8.
Embodiment
, below will be to technology of the present utility model to make the purpose of this utility model, technical scheme and advantage clearer
Scheme is described in detail；Any one skilled in the art in the technical scope that the utility model discloses,
Change or replacement can be readily occurred in, should all be covered within the scope of protection of the utility model.Therefore, protection of the present utility model
Scope should be based on the protection scope of the described claims.
The utility model single-bearing supporting carrier roller is specific to 45 ° of the side carrying roller and pipe conveyer of U-shaped ribbon conveyer
12 side shape carrying rollers carry out Aided design, and existing carrying roller is all to use roller circle both sides bearing support structure, the width of two bearings
Degree adds the width of both sides sealing device plus the width of bearing block, causes the minimum widith after carrying roller reduction far beyond dead
The space width of Angle Position.
As shown in drawings, the utility model single-bearing supporting carrier roller, employ the single installation of bearing 2 and be supported on support shaft 1
Between roller circle 8, bearing 2 is sequentially installed with labyrinth seal inner ring 3, labyrinth external seal outer ring 4, the and of cover lid 5 respectively outward from interior
Protective cover 6.The both sides of support shaft 1 are provided with back-up ring 7 along the outside installation site of protective cover 6.
The use of the utility model single-bearing supporting carrier roller solves the problems, such as dead angle, compensate for the deficiency of roller rack.
It is supported using the single two pairs of rollers circle 8 of bearing 2, the length of roller circle 8 is unsuitable long, so carrying roller length is short, meets carrier roller frame dead angle
The space requirement of position.The both sides of bearing 2 can improve the wearability of supporting mechanism using labyrinth seal, and labyrinth seal seals in itself
Property is good, rotational resistance is small, extends the service life of carrying roller.
