Abstract

The invention relates to the field of machinery, in particular to a transmission roller. The transmission roller is characterized in that the roller comprises a tubular roller body; the two shaft ends of the roller body are connected with shaft heads correspondingly; the roller body is fixedly connected with the shaft heads through tensioning devices; each tensioning device comprises an inner ring, an outer ring, a sleeve ring and two conical sleeve rings, wherein the inner ring and the outer ring are concentric, the sleeve ring is arranged between the inner ring and the outer ring and connected with the inner ring and the outer ring, and the two conical sleeve rings are clamped between the inner ring and the outer ring and arranged oppositely; each conical sleeve ring comprises an annular bottom surface and a plurality of sleeves which are uniformly arranged on one side of the annular bottom surface and have a certain taper; internal threads of the sleeves penetrate through the annular bottom surface; the sleeves are matched with internal threads of the sleeve rings; connecting bolts with the corresponding number of the sleeves are arranged; the taper matched with the sleeves is arranged on the inner side face of each outer ring; the taper matched with the sleeves is arranged on the outer side face of each inner ring. The transmission roller is simple in structure, convenient to disassemble and assemble and long in service life.

Description

A kind of live roll

Technical field

The present invention relates to mechanical field, particularly relate to a kind of live roll.

Background technology

In field of textile machinery, the live roll of existing Weaving device is normally at two welded flange spindle nose of roll body, but the high temperature produced in welding can cause live roll be out of shape thus cannot reach desirable working accuracy, and welded flange spindle nose cost is high, inefficiency, in addition, this connection mode is not easy to assemble and overhaul, and when axle end wear or roll body damage, then needs integral replacing, waste time and energy, and substantially increase productive costs.

In view of above problem, be necessary the easy-to-mount live roll proposing a kind of improvement.

Summary of the invention

The object of the invention is to the shortcoming overcoming prior art, provide that a kind of structure is simple, the live roll of easy accessibility and long service life.

For achieving the above object, the technical solution used in the present invention is: a kind of live roll, comprise the roll body of tubulose, a spindle nose is connected respectively in the two axial ends of described roll body, described roll body and described spindle nose are fixedly linked by swelling device, described swelling device comprises concentric inner ring and outer ring, to be located between inner ring and outer ring and the collar be all connected with inner ring and outer ring, and be located between inner ring and outer ring, two tapered collar be oppositely arranged, described tapered collar comprises annular bottom surface and is evenly arranged in annular bottom surface side, there are a plurality of sleeve pipes of certain taper, the negative thread of described sleeve pipe runs through annular bottom surface, the negative thread of sleeve pipe and the collar matches, the tie bolt of configuration and sleeve pipe respective numbers, the medial surface of described outer ring arranges the tapering matched with sleeve pipe, the lateral surface of described inner ring arranges the tapering matched with sleeve pipe.

Further, the axis of described inner ring and outer ring is equipped with one section of through cracking.

Further, described tie bolt is socket bolt.

After adopting above technology, when tightening tie bolt, then two tapered collar inwardly move along tie bolt axis direction respectively simultaneously in opposite directions, thus there is radial deformation in the inner ring of compressing swelling device and outer ring, inner ring is connected with the outside face interference of spindle nose, outer ring is connected with the inside face interference of roll body, and above-mentioned connection mode is for passing on moment of torsion.The present invention compared with prior art tool has the following advantages:

1, avoid in prior art adopt welding manner to produce high temperature on the impact of live roll, use swelling device to connect by the effect of high strength bolt, between inner ring and spindle nose, between outer ring and roll body, produce huge enclasping force, moment of torsion is large, precision is high, reliable and stable, long service life.

2, installation, adjustment and demolition are more convenient, and simple to operate, have good positioning, and reduce the condemnation factor being engaged spindle nose and roll body, reusable, do not damage mating surfaces, greatly reduce productive costs and effectively improve production efficiency simultaneously.

Detailed description of the invention

Below in conjunction with drawings and Examples, the invention will be further described:

As shown in Figures 1 to 4, a kind of live roll, comprise the roll body 1 of tubulose, a spindle nose 2 is connected respectively in the two axial ends of described roll body 1, described roll body 1 is fixedly linked by swelling device 3 with described spindle nose 2, described swelling device 3 comprises concentric inner ring 301 and outer ring 302, to be located between inner ring 301 and outer ring 302 and the collar 303 be all connected with inner ring 301 and outer ring 302, and be located between inner ring 301 and outer ring 302, two tapered collar 304 be oppositely arranged, described tapered collar 304 comprises annular bottom surface and is evenly arranged in annular bottom surface side and has a plurality of sleeve pipes of certain taper, the negative thread of described sleeve pipe runs through annular bottom surface, the negative thread of sleeve pipe and the collar 303 matches, the tie bolt 305 of configuration and sleeve pipe respective numbers, described tie bolt 305 adopts socket bolt, the medial surface of described outer ring 302 arranges the tapering matched with sleeve pipe, the lateral surface of described inner ring 301 arranges the tapering matched with sleeve pipe.

In addition, the side of described inner ring 301 and outer ring 302 arranges one section and cracks 306.

After adopting above technology, when tightening tie bolt 305, then two tapered collar 304 inwardly move along tie bolt 305 axis direction respectively simultaneously in opposite directions, thus there is radial deformation in the inner ring 301 of compressing swelling device and outer ring 302, inner ring 301 is connected with the outside face interference of spindle nose 2, outer ring 302 is connected with the inside face interference of roll body 1, thus roll body 1 and spindle nose 2 is fixedly linked, and above-mentioned connection mode is for passing on moment of torsion.

Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
