Abstract
The utility model relates to a vertical roller on billet transmission and collection line, in particular to a vertical roller used on the billet transmission line, including a vertical shaft, two fixing plates and a roll. An oil way guiding roller is arranged on the vertical shaft which is fixed by an upper fixing plate and a lower plate. The vertical roll coater also includes bearing holders and a plurality of rollers. The vertical shaft, the roller and another roller form the inside ring, the rolling element and the outside ring of the roll shaft. The roller and the vertical shaft rotate relatively and so do the rollers. The upper and lower ends of the roll are connected with the upper and lower bearing holders. The utility model reduces friction and abrasion, achieves flexible rolling and improves the service period of the vertical roll coater, due to the adoption of the rolling friction.
Description
(1) technical field
The utility model relates to the perpendicular roller on a kind of steel billet conveying and the collection production line.
(2) background technology
The form that the perpendicular roller on the production line adopts axle and bearing shell to rotate is carried and collected to existing steel billet, owing to be subjected to the baking of temperature adjustment steel billet, cause the axle of unlike material not wait with bearing shell dilatancy amount, the grease of perpendicular roller is easily dried simultaneously, makes insufficient lubrication between axle and bearing shell, causes the bearing shell rapid wearing, or the axle of perpendicular roller is killed with bearing shell, the collision repeatedly of adding steel billet makes bearing shell cracked, cause vertical pivot to damage, so that the maintenance cost of spare part expense and replacing rises.Perpendicular simultaneously roller expands and stubbornly refuses to change, and also causes the billet surface serious damage, has had a strong impact on the bad quality of becoming a useful person of steel, has reduced the product hierarchy of steel billet.
(3) summary of the invention
The utility model has overcome the defective of existing perpendicular roller, and a kind of perpendicular roller of roller that is used for billet feeding line is provided.The perpendicular roller of this roller adopts rolling friction, reduces friction, reduces wear, and roller turn is flexible, has improved service life.
The utility model is achieved in that a kind of perpendicular roller of roller that is used for billet feeding line, comprise vertical pivot, fixed head, roller, vertical pivot is provided with oil circuit and leads to rolling element, vertical pivot is fixed by two fixed heads up and down, the perpendicular roller of this roller also comprises bearing block, roller, and vertical pivot, roller, bearing block are formed inner ring, rolling element and the outer ring of roller bearing, and roller forms relative rolling with vertical pivot, also form relative rolling between roller and roller, the roller upper and lower side is fixedlyed connected with two bearing blocks up and down.
The above-mentioned roller that is used for billet feeding line erects roller, and the gap radial clearance of described bearing block and roller is 0.3～0.4mm, and end play is 0.34～0.43mm, and the total backlash between roller is 3.6～3.9mm.
Operation principle of the present utility model is that the sliding friction with original vertical pivot and bearing shell changes rolling friction into, with vertical pivot, roller, bearing block inner ring, rolling element and outer ring as roller bearing, roller forms relative rolling with vertical pivot, also form relative rolling between roller and roller, roller and up and down two bearing block interference fit link into an integrated entity.Can reduce friction like this, reduce wear, roller turn is flexible, improves the scope of application.
(4) description of drawings
Fig. 1 is used for the structural representation of the perpendicular roller of roller of billet feeding line for the utility model.
Fig. 2 is existing perpendicular roll structure schematic diagram.
Among the figure: 1 (vertical pivot), 2 fixed heads, 3 rollers, 4 rollers, 5 bearing blocks, 6 bearing shells.
(5) specific embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, a kind of perpendicular roller of roller that is used for billet feeding line comprises vertical pivot 1, fixed head 2, roller 3, bearing block 5, roller 4, and vertical pivot 1 is provided with oil circuit and leads to roller 4, and roller 4 is lubricated.Vertical pivot 1 is by two fixed heads 2 are fixing up and down, vertical pivot 1, roller 4, bearing block 5 are formed inner ring, rolling element and the outer ring of roller bearing, roller 4 forms relative rolling with vertical pivot 1,4 of roller 4 and rollers also form relative rollings, and roller 3 upper and lower sides are that interference fit is connected one with two bearing blocks 5 up and down.Steel billet slips over from roller 3, and roller 3 slides thereupon.For roller 3 is rotated flexibly, wearing and tearing reduce, and when bearing block 5 internal diameters were 85mm, the gap of bearing block 5 and roller 4: radial clearance was 0.3～0.4mm, and end play is 0.34～0.43mm, and the total backlash that roller is 4 is 3.6～3.9mm.
Claims (2)
1. a roller that is used for billet feeding line erects roller, comprise vertical pivot, fixed head, roller, vertical pivot is provided with oil circuit and leads to rolling element, vertical pivot is fixed by two fixed heads up and down, it is characterized in that the perpendicular roller of this roller also comprises bearing block, roller, vertical pivot, roller, bearing block are formed inner ring, rolling element and the outer ring of roller bearing, and roller forms relative rolling with vertical pivot, also form relative rolling between roller and roller, the roller upper and lower side is fixedlyed connected with two bearing blocks up and down.
2. the perpendicular roller of roller that is used for billet feeding line according to claim 1, the gap radial clearance that it is characterized in that bearing block and roller is 0.3～0.4mm, and end play is 0.34～0.43mm, and the total backlash between roller is 3.6～3.9mm.
