Accompanying drawing explanation
Fig. 1 is the structural representation of guide and guard deflector roll opening degree adjusting device of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is elaborated, can implement according to this after consulting this description to make those of ordinary skill in the art.
As shown in Figure 1, a kind of guide and guard deflector roll opening degree adjusting device, wherein, comprising:
Deflector roll, it comprises deflector roll body and guide roller axis 1, and described deflector roll body is set in described guide roller axis 1 outside and is driven by described guide roller axis 1 and carries out circumferential movement, and wherein said guide roller axis 1 is an eccentric shaft, and described guide roller axis 1 end is provided with connecting axle 2;
Worm gear 3, it is flexibly connected with the connecting axle 2 of described guide roller axis 1 end, described movable connection method is: described worm gear 3 offers the groove 4 matched with described connecting axle 2, described connecting axle 2 embeds in described groove 4, makes described guide roller axis 1 servo-actuated with described worm gear 3.Worm screw 6 and the outside pivot joint of described worm gear 3, described worm gear 3 is servo-actuated with described worm screw 6.Worm gear 3 is driven by worm screw 6 and rotates, and driving torque is passed to guide roller axis 1 by worm gear 3, and deflector roll then along with guide roller axis 1 does circumferential movement together, thus realizes the adjustment to deflector roll opening degree.
In addition, described worm gear 3 is also provided with pad 5, described pad 5 is provided with the perforate consistent with groove 4 shape and size, and described pad 5 is connected with worm gear 3 in the mode of perforate with groove 4 correspondence, and described pad 5 is arranged on the side that described worm gear 3 is flexibly connected with connecting axle 2.The effect of described pad 5 is equivalent to add the degree of depth of worm gear 3 upper groove in original device, thus worm gear 3 can be made to roll up with the contact area of connecting axle 2, the degree of depth of general worm gear 3 upper groove 4 is 5-10mm, and by increasing pad 5, the degree of depth of groove 4 can be made to be increased to about 18mm, thus to make the contact area of connecting axle 2 and groove 4 by original 320mm
2be increased to more than twice, can effectively relieve stresses concentrate, disperse stressed, alleviate the impact of rolled piece to worm gear 3 and deflector roll mating surface, thus can better keep deflector roll opening degree on the one hand, reduce on the other hand the wearing and tearing to deflector roll and worm gear 3 mating surface, make rolling everything goes well with your work to carry out, and ensure the surface quality of rolled piece better.In addition, this scheme can be transformed on the basis of existing guide and guard deflector roll opening degree adjusting device, and can determine the thickness of pad 5 as required, convenient and easy.
