Abstract
The invention relates to a roller for a caster. A rotating shaft component is arranged in a roller shaft hole and comprises an outer shaft sleeve and an inner shaft sleeve; the outer shaft sleeve is arranged in the roller shaft hole in a sleeving manner and is fixedly connected with the roller; the inner shaft sleeve is arranged in the outer shaft sleeve in the sleeving manner; two ball collars are arranged between the outer shaft sleeve and the inner shaft sleeve; the inner shaft sleeve can rotate relative to the outer shaft sleeve; the outer edge of the roller is provided with an anti-wear sleeve. The roller can achieve a good anti-wear effect, and the service life of the roller is long.
Description
Technical field
The present invention relates to a kind of wheel, is a kind of castor roller specifically.
Background technology
Castor is widely used in every field, such as general hand barrow, supermarket shopping car, industrial go-cart etc., greatly facilitate the difficulty that people carry article, growing along with science and technology, the structure of castor have also been obtained to be optimized more, but when using castor, the roller of castor is generally on the low side for service life, due to regular and ground friction, easily make rolling wheel wear; All be provided with brake gear at existing castor, directly play braking action to brake facing and roller friction, more exacerbate the wearing and tearing of pair roller, and once rolling wheel wear rear braking sheet is owing to reducing with roller contact face or being difficult to contact and making braking action lose.
And existing roller generally makes made of plastic, directly rotating shaft is fixed on castor through shaft hole time fixing, uses for a long time, roller wheel shaft hole can be made to wear and tear, the serious result of use excessively affecting castor.
Summary of the invention
For the problems referred to above of existing castor, the present invention designs a kind of castor roller, and this roller has wear-resistant advantage.
Technical scheme of the present invention is: a kind of castor roller, comprise roller body, rotating axis component is provided with in described roller axis hole, described rotating axis component comprises outer shaft and internal axle sleeve, described outer shaft to be located in roller axis hole and to be fixedly connected with roller, and described internal axle sleeve is placed in outer shaft, is provided with two ball collars between outer shaft and internal axle sleeve, internal axle sleeve can rotate relative to outer shaft, and described roller outer edge is provided with wearing bush.
Described wearing bush is made up of internal layer and skin, and internal layer is Elastic plastic-rubber layer, and skin is scuff-resistant coating.
The invention has the beneficial effects as follows: roller of the present invention, in shaft hole, be provided with the structure that outer shaft and internal axle sleeve match, play the wear-resistant effect of countershaft; And outside roller, be provided with wearing bush, reduce wearing and tearing when roller and earth surface.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of this practical scuff-resistant coating.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As illustrated in fig. 1 and 2: in the roller axis hole of roller 5 of the present invention, be provided with rotating axis component, rotating axis component comprises outer shaft 4 and internal axle sleeve 3, outer shaft 4 to be located in roller axis hole and to be fixedly connected with roller 5, described interior axle 3 is placed in outer shaft 4, two ball collars 2 are provided with between outer shaft 4 and internal axle sleeve 3, internal axle sleeve 3 can rotate relative to outer shaft 4 cover, and roller 5 outer edge is provided with wearing bush 1.
Wearing bush 1 is made up of internal layer and skin, and internal layer is Elastic plastic-rubber layer 6, and skin is scuff-resistant coating 7.
Roller of the present invention arranges the mode being provided with internal axle sleeve and outer shaft cooperation respectively in shaft hole, and be provided with ball collar between, during use, roller bearing is placed in internal axle sleeve, by ball collar, internal axle sleeve is rotated relative to outer shaft, than existing merely by rotating shaft be directly enclosed within wear and tear in roller wheel shaft hole less; And at roller outer sleeve by the wearing bush be made up of Elastic plastic-rubber layer and abrasionproof side, Elastic plastic-rubber layer energy pair roller plays certain buffer action, and scuff-resistant coating can play good wear-resistant effect, increase the service life of roller.
Claims (2)
1. a castor roller, comprise roller body, it is characterized in that being provided with rotating axis component in described roller axis hole, described rotating axis component comprises outer shaft and internal axle sleeve, described outer shaft to be located in roller axis hole and to be fixedly connected with roller, and described internal axle sleeve is placed in outer shaft, is provided with two ball collars between outer shaft and internal axle sleeve, internal axle sleeve can rotate relative to outer shaft, and described roller outer edge is provided with wearing bush.
2. a kind of castor roller according to claim 1, is characterized in that described wearing bush is made up of internal layer and skin, and internal layer is Elastic plastic-rubber layer, and skin is scuff-resistant coating.
