Description
Technical field
The utility model relates to a kind of milling train transmission device, relates in particular to a kind of duo mill working roll synchronous transmission device.
Background technology
The effect of main gear of rolling mill is that the motion of motor and moment are passed to roll.On a lot of milling trains, main drive is made up of parts such as reductor, pinion stand, coupling spindle and shaft couplings at present.The motion of motor changes into the needed rotating speed of roll through reductor, and the motion that pinion stand transmits reductor and moment are distributed to two rolls, between pinion stand and roll by coupling spindle and shaft coupling transmission campaign and moment of torsion.This tumbler is connected with upper working rolls and lower working rolls respectively with two coupling spindles, has increased the load of milling train, even if adopt universal-joint spindle, connecting axle inclination angle also only has
, make working roll have larger radiai adjustment amount, just must lengthen coupling spindle, make like this to connect axial length and heaviness, affect performance and the board quality of milling train.And because coupling spindle is worked under the condition of the high speed of being everlasting, heavy duty, high inclination-angle, coupling spindle joint is fragile, causes economic loss, affects milling train efficiency.
Summary of the invention
In order to solve, existing duo mill main drive working roll radiai adjustment amount is little, coupling spindle increases mill load and the flimsy problem of joint, and the utility model provides a kind of duo mill working roll synchronous transmission device.
The technical scheme that the utility model technical solution problem is taked is:
The utility model is made up of geared linkage mechanism.Described geared linkage mechanism comprises topping roll gear, bottom roll gear, floating gear, fixed gear and connecting rod.Described top and bottom rolls gear is arranged on respectively on the roller head of top and bottom rolls, with top and bottom rolls coaxial rotation; Described fixed gear is connected with rolling-mill housing by fixed bar, and fixed gear can rotate by the axle on fixed bar, and engages with bottom roll gear; Described floating gear, between topping roll gear and fixed gear, engages with topping roll gear and fixed gear respectively; Topping roll gear is connected with described connecting rod by the connecting rod rotating shaft on gear with fixed gear with floating gear, floating gear, and connecting rod can rotate in the connecting rod rotating shaft on gear.
The beneficial effects of the utility model: simple in structure, compact, quality is light, and reliability is strong, have strengthened topping roll radiai adjustment amount, can realize top and bottom rolls Synchronous Transmission, and transmission is more steady.
Brief description of the drawings

In accompanying drawing: 1, topping roll 2, sheet material 3, bottom roll 4, topping roll gear 5, connecting rod 6, floating gear 7, connecting rod 8, fixed gear 9, bottom roll gear 10, rolling-mill housing 11, fixed bar.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 or 2, described geared linkage mechanism comprises topping roll gear 4, bottom roll gear 9, floating gear 6, fixed gear 8 and connecting rod 5,7.
As shown in Fig. 1 or 2, described top and bottom rolls gear 4,9 is arranged on respectively on the roller head of top and bottom rolls 1,3, with top and bottom rolls coaxial rotation, is sheet material 2 between top and bottom rolls; Described fixed gear 8 is connected with rolling-mill housing 10 by fixed bar 11, and fixed gear 8 can rotate by the axle on fixed bar 11, and engages with bottom roll gear 9; Described floating gear 6, between topping roll gear 4 and fixed gear 8, engages with topping roll gear 4 and fixed gear 8 respectively; Topping roll gear 4 is connected with described connecting rod 5,7 respectively by the connecting rod rotating shaft on gear with fixed gear 8 with floating gear 6, floating gear 6, and connecting rod can rotate in the connecting rod rotating shaft on gear.
As shown in Fig. 1 or 2, spindle on bottom roll gear 9 is connected with reductor, motor rotates power is passed to reductor, be converted into the needed rotating speed of roll through reductor, power is passed to bottom roll gear 9 by reductor, drives bottom roll 3 to rotate on the one hand, drives on the other hand fixed gear 8 to rotate, fixed gear 8 drives topping roll gear 4 to rotate through floating gear 6, and then topping roll gear 4 drives topping roll 1 synchronously to rotate.In the time that topping roll 1 moves up and down under press down system effect, floating gear 6 is automatically adjusted the position of attitude and gear engagement under connecting rod 5,7 effects, thereby realizes significantly radiai adjustment of topping roll 1.
A specific embodiment of the present utility model below:
As shown in Fig. 1 or 2, four gear equal and opposite in directions, the angle between fixed gear 6 and bottom roll gear 9 lines of centres and vertical line is
, gear centre is apart from being
, the angle between connecting rod 5 and 7 is
time, top and bottom rolls 1,2 centre-to-centre spacing reach maximum and are
, the angle between connecting rod 5 and 7 is
time, top and bottom rolls 1,2 centre-to-centre spacing reach minimum of a value and are
, topping roll 1 maximum radial regulated quantity is
.
One skilled in the art will understand that the embodiment of the present utility model shown in foregoing description and accompanying drawing only limits the present invention as an example and not.Every equivalence variation of making according to the design spirit in the utility model or modification or equal proportion zoom in or out etc., all should think and fall into protection domain of the present utility model.
