Technical field
The utility model relates to rotary shear equipment field in cold rolled strip steel production, also can be used for adjusting bearing clearance in other similar devices, is specifically related to disc scissors axle bearing play regulating device.
Background technique
Rotary side trimming shear is widely used in the production of the bands such as steel band, aluminium strip, copper strips, is used for the edge fault of shear band steel, improves the width accuracy with steel, is one of nucleus equipment of producing the cold rolled sheet product.The blade of rotary side trimming shear and the rotating accuracy of cutter shaft are to guarantee to shear smoothly and shear the little precondition of section burr, and excessive cutter shaft bearing clearance directly causes the play of blade and beats, and impact 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 by assembling or increase magnitude of interference realizes, not only needs adjustment operation very complicated 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 completed.
Summary of the invention
The purpose of this utility model is to provide a kind of disc scissors axle bearing play regulating device convenient to use, the utility model can be realized rapid adjustment cutter shaft bearing clearance in assembling, and can be in follow-up use, in the situation that the cutter shaft bearing clearance is adjusted in not dismounting.
For achieving the above object, the technological scheme that the utility model adopts is: disc scissors axle bearing play regulating device includes cutter shaft, cutter shaft bearing, bearing (ball) cover, fixing bolt; Cutter shaft is provided with the cutter shaft bearing, and the cutter shaft bearing is arranged on frame, and bearing (ball) cover is fixedly connected with frame by fixing bolt; It is characterized in that: it comprises the bearing clearance adjusting ring gear; The bearing clearance adjusting ring gear is provided with outside thread, and the inner side surface of bearing (ball) cover is provided with internal thread, and the outside thread of this internal thread and bearing clearance adjusting ring gear forms screw pair; Between bearing (ball) cover and cutter shaft, the annular space is arranged, an end of bearing clearance adjusting ring gear contacted with the cutter shaft bearing after revolving the annular space, and the bearing clearance adjusting ring gear is threaded with bearing (ball) cover.
The other end of described bearing clearance adjusting ring gear is provided with the outer shroud tooth, is fixedly connected with a locking tooth plate by 2 screws on bearing (ball) cover, and an end of locking tooth plate is provided with tooth, and the tooth on the locking tooth plate is meshed with the outer shroud tooth on the bearing clearance adjusting ring gear.
The beneficial effects of the utility model are:
1, this device can be realized the adjusting of cutter shaft bearing clearance, than the faster convenience of common way;
2, in the situation that not dismounting can be adjusted the cutter shaft bearing clearance;
3, after the bearing clearance adjustment is completed, can lock play.
