Abstract
The utility model discloses a radial adjusting device of Y type rolling mill roll belongs to three -roller bar and shape mill technical field. Y type rolling mill roll vestibule is fixed in solving prior art, can't carry out the radial adjustment, leads to vestibule grow when the roll roll surface weares and teares, influences the size of mill bar. This adjusting device includes frame, roll, pushes down the screw rod, axle, bearing frame, resilient means, sleeve, skewed tooth bevel gear and key. Characterized by bearing frame upper portion with push down the screw rod and contact, the lower part contacts with resilient means, the sleeve be clearance fit with the axle, sleeve and skewed tooth bevel gear pass through the key -type connection. Through forcing down the screw rod, skewed tooth bevel gear and sleeve move on the axis direction of cooperation axle with it, and adjacent epaxial skewed tooth bevel gear and sleeve also move the same displacement volume on its axis direction that corresponds the axle in the gear pair transmission simultaneously, and whole adjusting device is used for realizing simultaneously the radial adjustment of Y type rolling mill roll through three couples of the same skewed tooth bevel gear are vice.
Description
Technical field
The utility model relates to a kind of rolling mill roll radial adjustment device, discloses a kind of y-type rolling mill roll radial adjustment device.
Background technology
Y-type rolling mill is made up of the disc roll being mutually 120 degree of angles, and roll mandrel through roll, and is tightened by end bolt, and breaker roll and axle position at axis direction.Roll mandrel support end installs rolling bearing, and a roll mandrel is driving shaft, and drives the bevel gear on other two axles rotate thus realize roll rotation by angular wheel.The radial position of this type of y-type rolling mill roll is fixing, generally radiai adjustment cannot be carried out, this will cause when roll surface weares and teares, roll aperture becomes large, the dimensional accuracy of stocking cannot be ensured, if directly carry out radiai adjustment, its central driving can become because of bevel gear meshing relation and be difficult to realize.
Summary of the invention
The utility model solves the y-type rolling mill roll radial direction existed in prior art and can not regulate, and affects stocking dimensional accuracy problem, provides a kind of y-type rolling mill roll radial adjustment device.
For solving the problem, the technical scheme that the utility model adopts is:
For solving the problem, the technical scheme that the utility model adopts is:
This radial adjustment device comprises frame, roll, depress spiro rod, axle, bearing block, elastic device, sleeve, helical bevel gear and key; It is characterized in that bearing block 2 top contacts with depress spiro rod 4, bottom contacts with elastic device 10; Sleeve 6 is connected by feather key 7 with axle 1, and sleeve can axially move by axle relatively; Helical bevel gear 8 is connected by key 5 with sleeve 6; Helical bevel gear 8 and helical bevel gear 9 engaged transmission completely; All the other two rolls are also contacted with depress spiro rod by bearing block top, bottom contacts with elastic device, and sleeve is connected by feather key with axle, and sleeve can axially move by axle relatively, helical bevel gear is connected by key with sleeve, and helical bevel gear and helical bevel gear engage realize transmission completely.
Utility model works principle: by depressing depress spiro rod, helical bevel gear and sleeve move on the axis direction of fitted shaft with it, the displacement that helical bevel gear simultaneously in gear pair transmission on adjacent shaft and sleeve are also mobile identical on the axis direction of its respective shaft, whole adjusting device is used for realizing y-type rolling mill roll radiai adjustment to identical helical bevel gear pair by three simultaneously.
The utility model is owing to adopting above technical scheme, technique effect: enable roll have the displacement of 0-5mm in radial direction, and bevel gear meshing relation can not change while adjustment.
Governor motion is simple, and cost is low, and accurately can realize three rollers radiai adjustment simultaneously.
In radiai adjustment process, gears meshing can not conjugate, and life expectancy is accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, power transmission shaft; 2, bearing block mechanism; 3, roll; 4, depress spiro rod; 5, key; 6, sleeve; 7, feather key; 8, helical bevel gear a; 9, helical bevel gear b; 10, elastic device.
Detailed description of the invention
For the single shaft transmission shown in Fig. 1, breaker roll carries out radiai adjustment.Three roller depress spiro rod O1, O2 are downward knobbling rolls bearing block simultaneously, band moving axis 1 moves down, axle 1 moves down to drive and is arranged on its two ends, left and right helical bevel gear and moves down, helical bevel gear 8 is connected with sleeve 6 by key 5, sleeve 6 is connected with axle 1 by feather key 7, and the relative axle 1 of sleeve 6 can move axially, therefore in pressure process, helical bevel gear 8 can be with moving sleeve 6 to move on axle 1 under the reaction force of the helical bevel gear 9 be engaged with; Due to the meshing relation of gear pair, helical bevel gear 9 also can move same displacement amount, and does not change two gearing relationships.In like manner, other two rolls can realize synchronous radiai adjustment.
