2. owing to selected for use hydraulic motor with brake or motor,, further stopped the possibility of rolling mill roll line downslide thus so hydraulic motor or motor only need very little stopping power just can obtain amplifying tens of times braking effect as transmission device.
3. because a worm gear mandrel in the above-mentioned self-locking governor motion or a whole level gear shaft are designed to hollow shaft, its endoporus is linked together by the gear shaft suit of singly-bound, two key or spline and travelling gear, make the self-locking governor motion have underslung structure, it is very convenient that its self-locking governor motion is installed.
4. owing on the self-locking governor motion, designed anti-rotation device, can either active balance self-locking governor motion gravity and the additional moment that produced when transmitting by anti-rotation device, can make self-locking governor motion easy accessibility again.
In a word, the utility model multi-roll mill roll line adjusting device is adjusted the precision height, and adjusted rolling mill roll line is highly stable, and it is very convenient that underslung structure is installed, and is specially adapted to the working condition that bottom working roll in the multi-roll mill uses eccentric adjusting and locking.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model multi-roll mill roll line adjusting device is described in further detail.
Fig. 1 is the utility model multi-roll mill roll line adjusting device scheme of installation;
Fig. 2 is Fig. 1 left view.
Wherein: 1 worm gear, 2 worm screws, 3 self-locking governor motion casings, 4 connecting plates, 5 hydraulic motors or motor, 6 travelling gears, 7 bearings, 8,9 rolling-mill housing, 10 eccentric gears, 11 eccentric shafts, 12 times back rest supports rollers, 13 worm gear mandrels, 14 worm screw power shafts, 15 connecting holes, 16 times back support roller gripper shoes.
The specific embodiment
Shown in Fig. 1,2, the utility model multi-roll mill roll line adjusting device comprises power set and travelling gear 6.In order to guarantee the utlity model has the advantages of high practicability energy, power set are hydraulic motor or the motor 5 that has brake, and between power set and travelling gear 6, also be provided with the self-locking governor motion, the power shaft of this self-locking governor motion connects with the power output shaft of power set, and the output shaft of self-locking governor motion connects with the axle 8 of travelling gear 6.Wherein:
According to actual conditions, above-mentioned self-locking governor motion can be taked multiple embodiments, first embodiment is a worm-gear speed reducer, specific design is: worm gear mandrel 13 is hollow shaft, and the endoporus of worm gear mandrel 13 connects carry-over moment by key with axle 8 suits of travelling gear 6, and described key can be singly-bound, two key or spline; Worm screw 2 power shafts 14 link with the output shaft of hydraulic motor or motor 5.Like this, utilize worm-drive itself to have the characteristic that gearratio is big, can realize self-locking, thereby when carrying out the rolling mill roll line Height Adjustment, both can refinement adjust precision, can obtain bigger ground self-locking moment again, in the Rolling Production process, can rolling mill roll line be locked with the frictional force acting in conjunction of 16 of eccentric shaft 11 and following back support roller gripper shoes again simultaneously, effectively prevent to shake the generation of the rolling line downslide phenomenon that is caused because of milling train in the production process.
Self-locking governor motion second embodiment is the multi-stage gear reductor, specific design is: the gear shaft of level eventually in the multi-stage gear is a hollow shaft, the endoporus of level gear shaft connects carry-over moment by key with axle 8 suits of travelling gear 6 eventually, and described key can be singly-bound, two key or spline; The output shaft of primary pinion power shaft in the multi-stage gear and hydraulic motor or motor 5 links; Wherein: multi-stage gear can be designed as 2 grades of transmissions according to actual needs, also can be 3 grades of transmissions.Like this, utilize the transmission campaign and the power of multi-stage gear, can make the adjusting self-locking mechanism have the big advantage of gearratio, the braking moment of power set is amplified, thereby not only improve the precision that rolling line is adjusted, and in the Rolling Production process, equally also can rolling mill roll line be locked with the frictional force acting in conjunction of 16 of eccentric shaft 11 and following back support roller gripper shoes, reach the purpose that solves the rolling line downslide problem that causes because of vibrations in the Rolling Production process.In addition, select for use hydraulic motor with brake or motor, then only need a very little stopping power just can obtain amplifying tens of times braking effect, further stopped the possibility of rolling line downslide thus as transmission device.
During installation, axle 8 with travelling gear in the utility model 6 is installed on the rolling-mill housing 9 by bearing 7 supportings earlier, travelling gear 6 meshes with the eccentric gear of the following back rest supports roller of milling train, the gear shaft of the eventually level gear in the mandrel 13 of worm gear 1 or the multi-stage gear is a hollow shaft, and 8 suit by singly-bound, two key or spline and travelling gear 6 are linked together; The self-locking governor motion can the whole outside that be suspended on rolling-mill housing 9 soon quick-detach in the utility model thus.
Additional moment when transmitting for the gravity of the above-mentioned self-locking hangingly of balance governor motion and moment of torsion also is provided with anti-rotation device to the influence of self-locking governor motion operation on the self-locking governor motion.This anti-rotation device is the connecting plate 4 that is arranged on the self-locking governor motion casing 3, has connecting hole 15 on the connecting plate 4; On rolling-mill housing 9 columns, be provided with and above-mentioned connecting plate 4, connecting hole 15 corresponding connecting plate and connecting holes, self-locking governor motion and rolling-mill housing 9 insertions be linked together with pin or with bolt.Like this, with pin or with the gravity that bolt can balance self-locking governor motion casing, the additional moment of moment of torsion transmission causes its casing 3 to rotate dismounting very easily in the time of also can preventing the work of self-locking governor motion.Individual resilient sleeve is arranged between pin and hole, or between two connecting plates a cushion is arranged, resilient sleeve or cushion can further play buffering and eliminate the effect of error.
When the rolling mill roll line height need be adjusted, drive hydraulic motor or motor 5, transmission worm-gear speed reducer or multi-stage gear reductor, eccentric gear 10 engagements of travelling gear 6 and milling train, eccentric gear 10 drives eccentric shaft 11 rotations, make a pair of down back support roller 12 split mutually or close, intermediate calender rolls rises or falls thereby drive down, realizes that finally bottom working roll adjusts up or down.After adjusting end-of-job, the brake in hydraulic motor or the motor 5 is held tightly, realizes the locking of rolling mill roll line height.
