Abstract
The utility model relates to a stripe steel supporting roller of a butt welding machine for wide strip steel. A Multi-section tandem support roller is composed of multiple sections of small supporting rollers which are sheathed on a core shaft 3. Each section of small supporting roller comprises two bearings 7, a bearing spacing ring 6 which is arranged between the two bearings, and a roller sleeve 5 which is supported on the two bearings. A bearing ring 4 is arranged between each two sections of small supporting rollers. Both ends of the core shaft are respectively clamped by a half sheet of bearing ring 2, a screw nut 1 and a shaft sleeve 8 to lead the multiple sections of small supporting rollers to form integration. The supporting roller which can be used for conveying material with a large breadth has the advantages of good shock absorbing property, good wear resisting property, long service life and convenient replacement of components.
Description
The utility model relates to the carrying roller of carrying wide flat steel, relates in particular to the band steel carrying roller of wide flat steel butt welder.
Carry the carrying roller width of wide flat steel bigger, what have reaches more than 2 meters, very high to the requirement of carrying roller.In the band steel carrying roller of wide flat steel butt welder, its roll surface usable length reaches 2187 millimeters, the high speed rotating that the body of roll changes with per minute 3000 when the operation of band steel.Existing band steel carrying roller from external introduction adopts seamless outer steel pipe to be enclosed within on the mandrel, rotate by the bearing supporting, because steel pipe length is big, and solid drawn pipe unavoidably exists the thickness of pipe inequality, causes when high speed rotating roller acutely to beat roll surface wearing, yielding, the general use once week must be changed, and because of roll surface width and carrying roller diameter ratio are very big, easily produces the carrying roller bending and causes stuck middle or damage other parts at electrode welder.The problem of 94238693.0 pairs of above-mentioned existence of Chinese patent is improved, and has proposed a kind of structure that adopts solid central roller, but the central roller processing difficulties of this structure, Heavy Weight uses inconvenient maintenance.
The purpose of this utility model is to provide a kind of multi-section serial formula carrying roller.This carrying roller is difficult for high vibration when high speed rotating, long service life is easy to maintenance, and part processing is easy.
The utility model is achieved in that a kind of multi-section serial formula carrying roller, comprise mandrel, it is characterized in that this carrying roller is composed in series on mandrel by the little support roller sleeve of more piece, the little carrying roller of every joint comprises two bearings, be contained in two between bearing bearing space ring, be bearing in two roller shells on the bearing, between the little carrying roller of every joint bearing collar is housed, the mandrel two ends clamp with half sheet bearing collar, nut and axle sleeve the little carrying roller of more piece are formed a whole.
In above-mentioned multi-section serial formula carrying roller, protrude in the middle of the roller shell inside face, convex shoulder props up two bearings.
In above-mentioned multi-section serial formula carrying roller, bearing collar is a bulge loop, and the bearing collar inside face is that annulus is enclosed within on the mandrel, and the bearing collar outside face is outstanding bulge loop.
In above-mentioned multi-section serial formula carrying roller, the biend chamfering that bearing collar outside face bulge loop is outstanding matches with roller shell end inside face.
The utility model multi-section serial formula carrying roller adopts the little carrying roller of more piece to be connected into a big carrying roller, and the centnifugal force that can disperse body of roll unbalanced weight to produce in use can avoid producing high vibration; Even the carrying roller bending, but because whole carrying roller is made up of the little carrying roller of more piece, one or two little carrying rollers are not worked and are not influenced the work of whole carrying roller, can not cause carrying roller to be beated yet, so carrying roller can turn round when high speed rotating steadily.This idler structure is simple, convenient disassembly, and replaceable local parts can be saved spare part expense, long service life greatly.
Fig. 1 is the structural representation of the utility model multi-section serial formula carrying roller.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, it is on 2095 millimeters the manufacturing line of conveying wide flat steel that multi-section serial formula carrying roller is applied to require roll surface width, adopt the 10 little support roller sleeves of joint series connected structure on mandrel 3, the little carrying roller of every joint comprises two bearings 7, is contained in the bearing space ring 6 of 7 on two bearings, is bearing in two roller shells 5 on the bearing 7.Roller shell 5 inside faces protrude, and convex shoulder props up two bearings 7, and bearing 7 is by bearing space ring 6 and axle sleeve 5 inside face convex shoulders location.Between the little carrying roller of every joint bearing collar 4 is housed, bearing collar 4 is a bulge loop, and bearing collar 4 inside faces are that annulus is enclosed within on the mandrel 3, and bearing collar 4 outside faces are outstanding bulge loop; The biend chamfering that this bulge loop 4 is given prominence to matches with roller shell 5 end inside faces, enters into bearing 7 in order to stop dust and other impurities, prolongs the service life of bearing.The little carrying roller of every joint adds that bearing collar 4 is enclosed within on the mandrel 3 and couples together, form an in-line carrying roller, install half sheet bearing collar 2 additional at the little carrying roller of first segment at mandrel 3 two ends and the outside of the little carrying roller of final section, these half sheet bearing collar, 2 outer one sides are planar rings, screw on again circular nut 1 and axle sleeve 8, axle sleeve 8 has circular hole, and elastic cylindrical pin 9 passes axle sleeve 8 holes and mandrel 3 holes form a whole the little carrying roller of more piece.Roller shell 5 outside faces scribble high-abrasive material or make with wear-resistant material, in order to prolong the service life of roller shell.
Present embodiment is applied to use on the Baosteel 2030 cold-rolling pickling unit kink dollies, and the use practice through 5 wheat harvesting periods has obtained good effect.
The utility model Multi-section tandem support roller has good vibration damping and wearability, and makes Long with the life-span, it is convenient to change parts, can be widely used in needing to carry the holder of wide format material Roller is specially adapted to metallurgy industry.
