Description

A kind of live-roller

Technical field

This utility model relates to mechanical field, particularly relates to a kind of live-roller.

Background technology

In field of textile machinery, the live-roller of existing Weaving device is typically two welded flange at roll body Spindle nose, but the high temperature produced in welding can cause live-roller deformation thus be unable to reach preferable machining accuracy, And welded flange spindle nose cost is high, inefficiency, additionally, this connected mode is the most easy to assemble and maintenance, work as axle Head abrasion or nunchakus body are damaged, then need integral replacing, waste time and energy, and substantially increase production cost.

In view of problem above, it is necessary to propose the easy-to-mount live-roller of a kind of improvement.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of simple in construction, dismounting side Just with the live-roller of length in service life.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of live-roller, including tubulose Roll body, the two axial ends at described roll body connects a spindle nose respectively, and described roll body and described spindle nose are by rising Tight device is fixedly linked, and described swelling device includes concentric inner ring and outer ring, is located between inner ring and outer ring And the collar being all connected with inner ring and outer ring, and be located between inner ring and outer ring, be oppositely arranged two Tapered collar, described tapered collar includes annular bottom surface and is uniformly arranged in annular bottom surface side, has one Determining a plurality of sleeve pipes of tapering, the female thread of described sleeve pipe runs through the female thread of annular bottom surface, sleeve pipe and the collar Matching, configuration and the connecting bolt of sleeve pipe respective numbers, the medial surface of described outer ring is arranged and sleeve pipe phase The tapering joined, the lateral surface of described inner ring arranges the tapering matched with sleeve pipe.

Further, described inner ring and outer ring be axially equipped with one section of through cracking.

Further, described connecting bolt is hexagon socket head cap screw.

After using above technology, when tightening connecting bolt, then two tapered collar are respectively along connecting bolt axis Direction inwardly moves towards simultaneously, thus oppresses inner ring and outer ring generation radial deformation, the inner ring of swelling device Being connected with the outer surface interference of spindle nose, outer ring is connected with the inner surface interference of roll body, and above-mentioned connected mode is used for Transmission moment of torsion.This utility model compared with prior art has the advantage that

1, avoiding the high temperature using welding manner to produce in the prior art impact on live-roller, use is risen Tight device connects through the effect of high-strength bolt, produces between inner ring and spindle nose, between outer ring and roll body Huge enclasping force, moment of torsion is big, and precision is high, and reliable and stable, service life is long.

2, install, adjust and demolition is more convenient, and simple to operate, have good positioning, reduce and coordinated Spindle nose and the scrappage of roll body, reusable, do not damage matching surface, greatly reduce production cost same Time be effectively increased production efficiency.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail:

As shown in Figures 1 to 4, a kind of live-roller, including the roll body 1 of tubulose, at the two of described roll body 1 Axle head connects a spindle nose 2 respectively, and described roll body 1 is fixedly linked by swelling device 3 with described spindle nose 2, Described swelling device 3 includes concentric inner ring 301 and outer ring 302, be located at inner ring 301 and outer ring 302 it Between and the collar 303 that is all connected with inner ring 301 and outer ring 302, and be located in inner ring 301 and outer ring 302 Between, two tapered collar 304 being oppositely arranged, described tapered collar 304 includes annular bottom surface and all The even a plurality of sleeve pipes being arranged in annular bottom surface side and having certain taper, the female thread of described sleeve pipe runs through Annular bottom surface, the female thread of sleeve pipe and the collar 303 matches, configuration and the connecting bolt of sleeve pipe respective numbers 305, described connecting bolt 305 uses hexagon socket head cap screw, and the medial surface of described outer ring 302 is arranged and sleeve pipe The tapering matched, the lateral surface of described inner ring 301 arranges the tapering matched with sleeve pipe.

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

After using above technology, when tightening connecting bolt 305, then two tapered collar 304 are respectively along connecting Bolt 305 axis direction inwardly moves towards simultaneously, thus oppresses inner ring 301 and the outer ring 302 of swelling device Radial deformation occurs, and inner ring 301 is connected with the outer surface interference of spindle nose 2, and outer ring 302 is interior with roll body 1 Surface interference connects, thus roll body 1 and spindle nose 2 is fixedly linked, and above-mentioned connected mode is used for passing on moment of torsion.

Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with this The personage of item technology will appreciate that content of the present utility model and implements according to this, can not limit this practicality with this Novel protection domain.All equivalence changes made according to this utility model spirit or modification, all should contain Cover within protection domain of the present utility model.
