Large-bearing universal caster easy to assemble and disassemble

Abstract

The invention discloses a large-bearing universal caster easy to assemble and disassemble. The universal caster comprises a steering device, a caster support, a roller and a roller shaft, wherein the steering device comprises a skewing bearing and a rotating shaft; the rotating shaft is embedded into the skewing bearing; the rotating shaft is sequentially connected to a first deep groove ball bearing, a plane bearing and a second deep groove ball bearing from top to bottom; the bottom of the rotating shaft is vertically connected to a reinforcing plate; the caster support comprises two ear plates vertically connected to the two sides of the reinforcing plate; each ear plate is provided with a shaft hole; the shaft holes of the two ear plates are arranged on the same horizontal axis; the roller is rotationally connected to the roller shaft; the roller is arranged between the two ear plates; the two ends of the roller shaft penetrate through the shaft holes of the ear plates respectively; and the two ends of the roller shaft are connected to fixing pieces. By modifying the structure of the caster, the caster can bear large load, the roller shaft of the roller can be quickly assembled and disassembled, and the rubber on the surface of the roller can be replaced conveniently.

Description

technical field [0001] The invention relates to the technical field of casters, in particular to a large load-bearing and easy-to-assemble universal caster. Background technique [0002] With the rise of the industrial revolution, more and more equipment needs to be moved. After people invented the wheel, it became much easier to carry and move objects, but the wheel can only run in a straight line, and it is difficult to change the direction when carrying heavy objects. Still very difficult, people just invented the wheel with steering structure afterwards, just we call caster. [0003] The casters can not only be carried easily, but also can be moved in any direction, which greatly improves the efficiency. With the continuous development of science and technology, people continue to pursue the convenience and efficiency of equipment movement, and casters have become an indispensable part. The development of the caster mechanism has become more specialized and has become ...
