Abstract
Y type rolling mill axle clearance eliminates structure has overcome present Y type rolling mill and after a period operation, because any one footstep bearing's wearing and tearing all can lead to the fact the main shaft along the axial direction drunkenness, has brought the problem that influences Y type rolling mill pass precision, footstep bearing is installed in the axial adjustment nut left and right sides to the characteristic, axial position between main shaft and the axial adjustment nut passes through left and right sides footstep bearing relatively fixed, at axial adjustment nut right side installation axle head gland, processing has the through -hole and installation clearance elimination bolt in this through -hole on the axle head gland, eliminating the bolt front end in the clearance is equipped with clearance elimination clamp plate, the bolt is eliminated through adjusting play and rolling mill axle clearance can be thoroughly eliminated, line type aliphatic epoxide, when the wearing and tearing of Y type rolling mill operation a period footstep bearing, can be fast thoroughly eliminate the betweencenters clearance, moreover, the steam generator is simple in structure, and is convenient in regulation, the efficiency of rolling mill work is improved with rolling quality.
Description
Technical field
This utility model belongs to metal rolled technical field, eliminates structure particularly to y-type rolling mill axial gap.
Background technology
Three-roller Y shaped milling train of the prior art, some employing bevel gear group central driving, have by c-type frame gear-box group transmission, their common feature is to be assigned on 3 roller mill main axles by 1 motor-driven 1 main axis, the adjustment of axial gap is by the pad of main shaft both sides realization is increased or decreased, the adjustment of axial gap is required for dismounting frame every time, axially adjustable for roll brings very big inconvenience, not only adjust the used time oversize, and Adjustment precision is relatively low, affect work efficiency and the rolling quality of milling train, and, y-type rolling mill is after running after a while, because the abrasion of any one thrust bearing, main shaft in axial direction play will be caused, affect the pass precision of y-type rolling mill.
Summary of the invention
Problem to be solved in the utility model is, in place of overcoming the deficiencies in the prior art and defect, it is provided that a kind of y-type rolling mill axial adjusting structure that can axial gap be thoroughly eliminated.
The technical solution adopted in the utility model includes main shaft, the outside bearing set of the right-hand member of main shaft, eccentric bushing is filled at bearing outside, in eccentric bushing and between main shaft, axially adjustable nut is installed, in the axially adjustable nut left and right sides, thrust bearing is installed, axial location between main shaft and axially adjustable nut is relatively fixed by left and right sides thrust bearing, on the right side of axially adjustable nut install axle head gland, axle head gland is machined with through hole and in this through hole assemblage gap eliminate bolt.
Eliminate bolt front end in described gap and be provided with gap elimination pressing plate.
Compared with prior art, the beneficial effects of the utility model are: at y-type rolling mill after running after a while, when thrust bearing weares and teares, adjust gap and eliminate bolt, promote thrust bearing to be close to axially adjustable nut, axial gap thoroughly can be eliminated, simple in construction, easy to adjust, improve milling train work efficiency and rolling quality.
Accompanying drawing explanation

Fig. 3 is the A portion enlarged drawing of Fig. 1.
In figure:
1. main shaft, 2. eccentric bushing,
The most axially adjustable nut,
4. gap eliminates bolt, 5. thrust bearing, 6. axle head gland,
7. eccentric bushing gland, 8. bearing, 9. roll.
Detailed description of the invention
nullAs depicted in figs. 1 and 2，The technical solution adopted in the utility model includes main shaft 1，Described main shaft 1 is an axis，The left end of main shaft 1 is provided with roll 9，The outside bearing set 8 of the right-hand member of main shaft 1，At bearing 8 outer suit eccentric bushing 2，In eccentric bushing 2 and between main shaft 1, axially adjustable nut 3 is installed，In axially adjustable nut 3 left and right sides, thrust bearing 5 is installed，Axial location between main shaft 1 and axially adjustable nut 3 is relatively fixed by left and right sides thrust bearing 5，Axle head gland 6 is installed on the right side of axially adjustable nut 3，Left side thrust bearing 5 is positioned by main shaft 1 right-hand member second shaft shoulder，Right side thrust bearing 5 is positioned by axle head gland 6，Axle head gland 6 is machined with through hole and in this through hole assemblage gap eliminate bolt 4，The contact area of bolt 4 and thrust bearing 5 is eliminated in order to increase gap，Described gap eliminates bolt 4 front end and is provided with gap elimination pressing plate，In the right side of eccentric bushing 2, eccentric bushing gland 7 is installed.
During use, at y-type rolling mill after running after a while, and when thrust bearing 5 weares and teares, adjust gap and eliminate bolt 4, promote thrust bearing 5 to be close to axially adjustable nut 3, axial gap thoroughly can be eliminated with this.
Claims (2)
