Abstract

The utility model relates to a combined type detachable wear-resistant shaft sleeve and belongs to the field of machining equipment. The combined type detachable wear-resistant shaft sleeve consists of a roll shaft and single-section wear-resistant sleeves, wherein each single-section wear-resistant sleeve consists of two pieces of paired wear-resistant semicircular sleeves; the two pieces of paired wear-resistant semicircular sleeves are correspondingly connected into an integrated single-section wear-resistant sleeve by radial end surfaces; a plurality of single-section wear-resistant sleeves are butted by adjacent axial end surfaces and are respectively and correspondingly fastened and connected by axial key grooves on the inner surfaces of all single-section paired wear-resistant semicircular sleeves and flat keys on the surface of the roll shaft so as to be completely sheathed on the surface of the roll shaft. The combined type detachable wear-resistant shaft sleeve replaces the traditional wear-resistant sleeve with the whole structure; and when the local part of the wear-resistant sleeve is worn and fails, the wear-resistant sleeve with worn sections can be locally detached and can be replaced with a new wear-resistant sleeve, so that the disassembly, assembly, replacement, repair and maintenance are convenient, the waste of material resources caused by whole replacement of the wear-resistant sleeve is avoided and the repairing time is saved.

Description

A kind of Combined detachable anti-wear sleeve

Technical field

A kind of Combined detachable anti-wear sleeve of the utility model, belongs to machine up equipment field.

Background technology

At present, the rollgang wear-resistant sleeve of section bar processing is all whole wear sleeve, while carrying on roller-way due to section bar, produce abrading section inhomogeneous, make conveying roller wear sleeve because localized wear seriously scraps, cause the great wasting of resources, and when wear sleeve is changed in installation or removal, must will under rollgang dismounting, change wear sleeve, the integral replacing time must cause the mechanical equipment can not normal operation compared with growing way, affected whole manufacturing schedule, for saving resource, reduce costs, reduce maintenance time, short in the urgent need to developing the installation and maintenance time, novel wear resistant cover that can local convenient changing.

Utility model content

The purpose of this utility model is to provide a kind of Combined detachable anti-wear sleeve, to adapt to the maintenance of roll shaft localized wear, economizes on resources, and improves the service life of roll shaft.

The purpose of this utility model is achieved through the following technical solutions:

A kind of Combined detachable anti-wear sleeve of the utility model, by roll shaft and single segmental wear sleeve, formed, described single segmental wear sleeve is comprised of two paired wear-resisting half round busses, these two paired wear-resisting half round busses connect as one single segmental wear sleeve by its radial end face correspondence, by the adjacent axial end of the wear-resisting jacket casing of more piece single segmental, docked, respectively by the axial keyway of the paired wear-resisting semicircle sleeve interior surface of each single segmental and corresponding being fastenedly connected of flat key on roll shaft surface, the complete roll shaft surface that is sleeved on.

Two paired wear-resisting its radial end faces of half round buss of described single segmental wear sleeve have respectively corresponding boss and the groove connecting.

The utility model has substituted traditional integral structure wear sleeve with Combined detachable anti-wear sleeve, when local wear sleeve wear out failure, can partial disassembly the wear-resistant sleeve that more renews of the wear sleeve of wearing and tearing sections, its disassembling, assembling and replacing maintenance is convenient, avoid the waste of the material resources that integral replacing wear sleeve causes, and saved maintenance time.

Accompanying drawing explanation

To be that the utility model is complete be sleeved on for mechanical equipment roll shaft schematic surface Fig. 1;

Fig. 2 is the wear-resisting half round buss schematic diagram of single segmental that the utility model is provided with radial end face boss;

Fig. 3 is the wear-resisting half round buss schematic diagram of single segmental that the utility model is provided with radial end face groove;

Fig. 4 is the wear-resisting half round buss connection diagrams of two paired single segmentals of the utility model;

Fig. 5 is the utility model single segmental wear sleeve and roll shaft connection diagram.

The specific embodiment

How now further illustrate by reference to the accompanying drawings the utility model implements:

A kind of Combined detachable anti-wear sleeve of the utility model, by roll shaft B and single segmental wear sleeve A, formed, described sections wear sleeve A is comprised of two paired wear-resisting half round buss A1 and A2, described wear-resisting half round buss A1 has boss 3, wear-resisting half round buss A2 fluted 4, wear-resisting half round buss A1 and A2 inside face are respectively equipped with axial keyway 5,6 in pairs, corresponding boss 3 by its radial end face of these two paired wear-resisting half round busses and groove 4 are connected and become single segmental wear sleeve A, and fastening through corresponding bolt hole with interior hexagonal screw bolt 1; By the adjacent axial end docking of more piece single segmental wear sleeve, respectively by the axial keyway 5,6 of each paired wear-resisting semicircle sleeve interior surface and the corresponding location that is in clamping connection of flat key 2 on roll shaft B surface, the complete surface that is sleeved on roll shaft B.

When local wear sleeve need to be changed because of wear out failure, do not need conveying roller to pull down integral replacing wear sleeve, can directly on roller-way, unscrew the interior hexagonal screw bolt 1 of the wear sleeve that need to change sections, two half round buss A1, A2 are disassembled respectively, with new wear-resisting half round buss, replacement is installed as stated above.

Claims

1. a Combined detachable anti-wear sleeve, it is characterized in that, by roll shaft and single segmental wear sleeve, formed, described single segmental wear sleeve is comprised of two paired wear-resisting half round busses, these two paired wear-resisting half round busses connect as one single segmental wear sleeve by its radial end face correspondence, by the adjacent axial end of the wear-resisting jacket casing of more piece single segmental, docked, respectively by the axial keyway of the paired wear-resisting semicircle sleeve interior surface of each single segmental and corresponding being fastenedly connected of flat key on roll shaft surface, the complete roll shaft surface that is sleeved on.

2. a kind of Combined detachable anti-wear sleeve according to claim 1, is characterized in that, two paired wear-resisting its radial end faces of half round buss of single segmental wear sleeve have respectively corresponding boss and the groove connecting.
