Abstract
The utility model provides a Y type rolling -mill roll leads to axle clamp and holds bearing structure, overcome current Y type rolling -mill roll and adopted 2 cavity semi -axis clamping structure, make quill carrying capacity descend, though or the bevel gear Y of group type rolling mill adopts logical axle to support, nevertheless change the inconvenient problem of roll, the roll is installed to the characteristic on the integral key shaft of main shaft, an installation lock nut and the 2nd lock nut on the screw spindle of roll left end face, the first bearing of suit on the main shaft left end supports, suit second bearing on the main shaft right -hand member supports, adorn first eccentric cover at first bearing overcoat, at the eccentric cover of second bearing overcoat dress second, connect through eccentric cover connecting piece between first eccentric cover and the eccentric cover of second, line type aliphatic epoxide, roll relatively low defect of main shaft rigidity in the adjustable structure of pushing down has been solved, the bearing capacity of the main shaft of installation roll can improve, assurance to product quality under the big rolling power production conditions provides the support, very big convenience has also been brought to changing the roll.
Description
Technical field
This utility model belongs to metal rolled technical field, particularly to a kind of y-type rolling mill roll axis clamp standoff structure.
Background technology
In prior art, the clamp standoff structure of y-type rolling mill roll has two kinds of forms, one is 2 hollow semiaxis clampings, with middle bolt, roll is fastened between 2 hollow semiaxis, this structure there is problems of, the main axis stiffness of 2 semiaxis compositions is relatively low, the bearing capacity causing main shaft declines, and circular runout is relatively large, has a certain impact product quality under big roll-force working condition；Although another kind of bevel gear group y-type rolling mill is to use axis to support, but, roll and bevel gear are mounted on same main shaft, when changing roll, simultaneously need to bevel gear is dismantled, causing the very big inconvenience changing roll, meanwhile, this structure also brings very big inconvenience for the radial and axial adjustment of roll.
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, and first, solve the roll defect that 2 semiaxis main axis stiffnesses are relatively low in the structure that adjustable is depressed；Second, solve bevel gear class milling train and change and adjust the problem that roll is inconvenient, it is provided that a kind of main axis stiffness is high, change and adjust roll a kind of y-type rolling mill roll axis clamp standoff structure easily.
The technical solution adopted in the utility model includes that main shaft and main shaft right-hand member support, described main shaft is an axis, the left end of main shaft is four layers of ledge structure, ground floor step is the locating shoulder for positioning roll, second layer step is splined shaft, third layer step is thread spindle, 4th layer rank are main shaft left end support, splined shaft is installed roll, the spline tooth of roll is engaged with splined shaft, the thread spindle of roll left side is installed the first locking nut and the second locking nut, main shaft left end support is set with clutch shaft bearing, it is set with the second bearing on main shaft right-hand member supports.
Outside clutch shaft bearing, it is set with the first eccentric bushing, fills the second eccentric bushing at the second bearing outside, connected by eccentric bushing connector between the first eccentric bushing and the second eccentric bushing.
Between roll right side and locating shoulder, pad is installed.
Compared with prior art, advantage of the present utility model and good effect are:
(1) it is an axis due to main shaft described in the utility model, the splined shaft that main shaft is arranged is installed roll, the spline tooth of roll is engaged with splined shaft, solve the roll defect that the main axis stiffness of two semiaxis compositions is relatively low in the structure that adjustable is depressed, the bearing capacity of the main shaft installing roll is improved, the guarantee of product quality under big roll-force working condition is provided support, also brings the biggest convenience to changing roll；
(2) this utility model installs the first eccentric bushing in main shaft left end support, supports at main shaft right-hand member and installs the second eccentric bushing, is connected by eccentric bushing connector, it is ensured that the first eccentric bushing and the second eccentric bushing synchronous rotary between the first eccentric bushing and the second eccentric bushing.
