Abstract

The invention discloses a hollow caster, which relates to the technical field of casters and aims to solve the technical problem of reduction in weight and manufacturing cost. The caster comprises an axle, a rolling bearing and annular belting leather, wherein the inner ring of the rolling bearing is fixedly connected with the axle. The hollow caster is characterized in that: the axle is a hollow hard round tube; and the belting leather is coaxially sleeved on the outer ring of the rolling bearing. The hollow caster provided by the invention has light weight and low manufacturing cost.

Description

technical field [0001] The invention relates to the technology of casters, in particular to the technology of hollow casters. Background technique [0002] At present, the bottoms of many suitcases and many tables and chairs are provided with casters. Such as Figure 5 As shown, the traditional casters are all formed by the axle 12, the rolling bearing 14, the wheel core 13 and the wheel belt 11 from the inside to the outside in sequence, wherein the wheel axle 12 is coaxially fixed with the inner ring of the rolling bearing 14, and the wheel core 13 and the rolling bearing The outer ring of 14 is affixed, plays the effect of supporting wheel belt 11, and wheel belt 11 and wheel core 13 drive the outer ring of rolling bearing 14 to rotate when this caster rolls, and the inner ring of rolling bearing 14 and wheel shaft 12 can not rotate. Although this caster has firm structure and strong bearing capacity, it has the defects of heavy weight, many materials used and high manuf...
