Abstract
The invention relates to a knife-shaft bearing clearance adjusting device of a disc shear. The knife-shaft bearing clearance adjusting device comprises a knife shaft, a knife shaft bearing, a bearing end cover and fixed bolts, wherein the knife shaft is provided with the knife shaft bearing which is arranged on a rack; and the bearing end cover is fixedly connected with the rack by the fixed bolts. The knife-shaft bearing clearance adjusting device is characterized in that the bearing end cover is provided with bearing clearance adjusting screws; and a pressure equalizing ring is arranged between each bearing clearance adjusting screw and the knife shaft bearing. The bearing end cover is provided with 2-30 adjusting screw internal thread holes, and the number of the bearing clearance adjusting screws is same as that of the adjusting screw internal thread holes; and one end of each bearing clearance adjusting screw rotates through each adjusting screw internal thread hole and then is contacted with the pressure equalizing ring. The knife-shaft bearing clearance adjusting device has the advantages that fast adjustment for the clearance of the knife shaft bearing can be realized, and the clearance of the knife shaft bearing can be adjusted in later use under the condition without disassembly and assembly; and after the clearance adjustment is finished, the clearance can be locked.
Description
Technical field
The present invention relates to rotary shear equipment field in the cold rolled strip steel production, also can be used for adjusting bearing clearance in other similar devices, be specifically related to a kind of circle shear cutter shaft bearing clearance adjusting device.
Background technology
The disk end trimming shears are widely used in being used for the edge fault of shear band steel in the production of bands such as steel band, aluminium strip, copper strips, improve the width accuracy of band steel, are one of nucleus equipments of producing the cold rolled sheet product.The blade of disk end trimming shears and the rotating accuracy of cutter shaft are to guarantee to shear and shear the little prerequisite of section burr smoothly, and excessive cutter shaft bearing clearance directly causes the play of blade and beats, and influence is sheared; And too small cutter shaft bearing clearance can cause the locked and damage of bearings of cutter shaft, and therefore suitable cutter shaft bearing clearance is most important.
Current, the method that increases pad when regulating the circle shear bearing clearance and be through assembling or increase the magnitude of interference realizes, not only need regulate the complex operation complicacy repeatedly, and pad minimum thickness 0.1mm, and the play precision is 0.01mm, is difficult to realize; And can't adjust in the use after assembling is accomplished.
Summary of the invention
The object of the present invention is to provide a kind of circle shear cutter shaft bearing clearance adjusting device, the present invention can realize rapid adjustment cutter shaft bearing clearance in the assembling, and can in follow-up use, under the situation of not dismounting, adjust the cutter shaft bearing clearance.
For realizing above-mentioned purpose, technical scheme provided by the invention is: a kind of circle shear cutter shaft bearing clearance adjusting device relates to cutter shaft, cutter shaft bearing, bearing (ball) cover, set bolt; Cutter shaft is provided with the cutter shaft bearing, and the cutter shaft bearing is arranged on the frame, and bearing (ball) cover is fixedly connected with frame by set bolt; It is characterized in that: bearing (ball) cover is provided with the bearing clearance adjustment screw, is provided with grading ring between bearing clearance adjustment screw and the cutter shaft bearing.
Described bearing (ball) cover is provided with 2-20 adjustment screw internal thread hole, and the number of bearing clearance adjustment screw is identical with the number of adjustment screw internal thread hole, and an end of bearing clearance adjustment screw contacts with grading ring after revolving and overregulating the screw internal thread hole.
The other end of described bearing clearance adjustment screw is rotary with locking nut.
The invention has the beneficial effects as follows:
1, this device can be realized the adjusting of cutter shaft bearing clearance, than the faster convenience of common way;
2, under the situation of not dismounting, can adjust the cutter shaft bearing clearance;
3, after the bearing clearance adjustment is accomplished, can lock play.
Description of drawings
Fig. 1 is an elevational schematic view of the present invention.
Among the figure: 1-blade, 2-cutter shaft, 3-frame, 4-cutter shaft bearing, 5-bearing (ball) cover, 6-bearing clearance adjustment screw, 7-locking nut, 8-grading ring, 9-set bolt, 10-bolt hole.
The specific embodiment
For a better understanding of the present invention, below in conjunction with accompanying drawing and embodiment technical scheme provided by the invention is done further explanation.
As shown in Figure 1, a kind of circle shear cutter shaft bearing clearance adjusting device relates to cutter shaft 2, cutter shaft bearing 4, bearing (ball) cover 5, set bolt 9; Cutter shaft 2 is provided with cutter shaft bearing 4; Cutter shaft bearing 4 is arranged on that (blade 1 is arranged on the cutter shaft 2 on the frame 3; Blade 1 is fixed on the cutter shaft 2 through hydraulic nut, and cutter shaft bearing 4 is installed in the hole of frame 3), bearing (ball) cover 5 is arranged on the frame 3; Bearing (ball) cover 5 is fixedly connected with frame 3 by set bolt 9 that (set bolt 9 is uniformly distributed with for 2-20; Bearing (ball) cover 5 is an annular, and bearing (ball) cover 5 is provided with a plurality of bolts hole 10; The bolt hole 10 that the left end of set bolt 9 passes on the bearing (ball) cover 5 is fixed on the frame 3; Bearing (ball) cover 5 is gapped with cutter shaft 2).Its (a kind of circle shear cutter shaft bearing clearance adjusting device) comprises grading ring 8, bearing clearance adjustment screw (or bearing clearance adjusting screw(rod)) 6 and locking nut 7; Bearing (ball) cover 5 is provided with bearing clearance adjustment screw 6; (grading ring 8 is enclosed within on the cutter shaft 2, and grading ring 8 is between cutter shaft bearing 4 and bearing (ball) cover 5 to be provided with grading ring 8 between bearing clearance adjustment screw 6 and the cutter shaft bearing 4; Grading ring 8 is gapped with cutter shaft 2).
Bearing (ball) cover 5 is provided with 2-20 adjustment screw internal thread hole, and the number of bearing clearance adjustment screw 6 is identical with the number of adjustment screw internal thread hole, and an end of bearing clearance adjustment screw 6 contacts with grading ring 8 after revolving and overregulating the screw internal thread hole.
The other end of described bearing clearance adjustment screw 6 is rotary with locking nut 7 (after the bearing clearance adjustment completion, can lock play).
During use, precession or back-out bearing clearance adjustment screw 6 change the gap between grading ring 8 and the cutter shaft bearing 4, under the situation of not dismounting, can adjust the cutter shaft bearing clearance; After adjustment was accomplished, locking nut 7 was the lockable play.
The bearing clearance size realizes through the moment of torque spanner control bearing clearance adjustment screw 6.
Above-describedly be merely preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, the equivalence of therefore doing according to claim of the present invention changes, and still belongs to protection scope of the present invention.
