Abstract
The utility model discloses a kind of guide wheel device for NTC multi-wire butting machine, comprise directive wheel main body, axle and bearing, the inner ring of bearing is assemblied on axle; Be installed with wear-resistant sleeve in the inner ring of described directive wheel main body, the outer ring of bearing is assemblied in wear-resistant sleeve, and is interference fit between the inner ring of the outer shroud of wear-resistant sleeve and directive wheel main body, is matched in clearance between the inner ring of wear-resistant sleeve and the outer ring of bearing.Low, the wear-resistant and easily changeable wear-resistant sleeve of the utility model assembly cost between the inner ring and bearing outer ring of directive wheel main body, the inner ring avoided because of directive wheel main body is worn and torn by twisting force, not only substantially prolongs the service life of directive wheel main body, and the directive wheel main body of scrapping because of inner ring serious wear in the past, can be reused by fit on wear-resistant sleeve, saved resources costs.
Description
Technical field
The utility model relates to a kind of guide wheel device for NTC multi-wire butting machine, belongs to monocrystalline cutting technique field.
Background technology
Early stage NTC multi-wire butting machine (as model MBS1000) is applied to now, and some designs are relatively backward, part replacement or maintenance more difficult, cause service life of equipment shorter.One of them is exactly the guide wheel device of this equipment, directive wheel main body is wherein used for guiding the walking travel direction of steel wire, the outer ring of bearing is directly assemblied in the inner ring of directive wheel main body, axle is assemblied in the inner ring of bearing, and is matched in clearance between the inner ring of the outer ring of bearing and directive wheel main body.But, because the direction of travel of steel wire may be inconsistent with the direction of the gathering sill in directive wheel body surfaces, directive wheel main body also can be subject to a torsion when rotating, and therefore in use for some time, the inner ring of directive wheel main body wearing and tearing very easily occurs and scraps and cannot use.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of anti abrasive guide wheel device for NTC multi-wire butting machine, extends the long service life of directive wheel main body.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
For a guide wheel device for NTC multi-wire butting machine, comprise directive wheel main body, axle and bearing, the inner ring of bearing is assemblied on axle; Be installed with wear-resistant sleeve in the inner ring of described directive wheel main body, the outer ring of bearing is assemblied in wear-resistant sleeve, and is interference fit between the inner ring of the outer shroud of wear-resistant sleeve and directive wheel main body, is matched in clearance between the inner ring of wear-resistant sleeve and the outer ring of bearing.
Wherein, described wear-resistant sleeve is fixedly connected by the inner ring of the countersunk head screw and directive wheel main body that are located at its radial direction.
Wherein, the material of described directive wheel main body is aluminium matter, and the material of wear-resistant sleeve is irony or steel.
The beneficial effect adopting technique scheme to produce is:
Low, the wear-resistant and easily changeable wear-resistant sleeve of the utility model assembly cost between the inner ring and bearing outer ring of directive wheel main body, avoid because the inner ring of aluminium matter directive wheel main body is because wearing and tearing by twisting force, not only substantially prolongs the service life of directive wheel main body, and the directive wheel main body of scrapping because of inner ring serious wear in the past, can be reused by fit on wear-resistant sleeve, saved resources costs.Usually, the expense of a set of new directive wheel main body is about 780 yuan, and adopts design of the present utility model, and the recondition expense of scrapping directive wheel main body is only 15 yuan/cover, and therefore, the simple transformation of low cost makes extend several times the service time of directive wheel.
The utility model is simple and practical, and wear-resistant sleeve is packed in the inner ring of directive wheel main body by sunk screw, installs firm and wear-resistant, neither affects the use of directive wheel main body, and wear-resistant sleeve cost is low and can directly change after wearing and tearing.
