Universal wheel convenient to disassemble and assemble and universal wheel set

Abstract

The invention discloses a universal wheel convenient to disassemble and assemble and a universal wheel set. The universal wheel comprises a roller and two wheel disc sheet bodies, wherein a pivot is stretched from the two corresponding ends of the roller respectively; a through hole for connecting a transmission shaft is formed at the center of the two wheel disc sheet bodies; multiple convex parts are convexly arranged on the outer periphery of the wheel disc sheet bodies along the radial direction; a containing space for containing the roller is formed between adjacent convex parts respectively; a groove is concavely formed on the two corresponding sides of the convex part and close to each containing space respectively, and the corresponding groove forms a pivot joint trough; and the pivot of the roller is in pivot joint with the pivot joint trough. Compared with the prior art, the invention has the advantages that the maintenance cost can be remarkably reduced, the universal wheel with the structural design is easy to disassemble and assemble, the maintenance processes are simplified, and the maintenance efficiency is improved.

Description

technical field [0001] The invention relates to a universal wheel and a universal wheel group which are convenient for disassembly and assembly. Background technique [0002] Universal movement refers to the meaning that vehicles and other devices can move in any direction at will under the condition that the facing direction remains unchanged. In order to make the vehicle achieve the effect of universal movement, manufacturers usually install universal wheels on the vehicle, so that the vehicle can move on the ground with universal wheels, and vehicles such as vehicles or robots equipped with universal wheels , generally known as universal mobile wheel vehicles. Since the universal mobile wheel-type vehicle has the advantages of flexible movement and steering, especially lateral and horizontal movement, it is quite suitable for places with limited activity space, such as warehouses, factories and other places. At present, universal wheels have been used in the fields of r...

AI Technical Summary

Problems solved by technology

Yet, no matter it is the oblique universal wheel 1 or the traditional universal wheel 2, there are still many shortcomings to be improved

In the above-mentioned known universal wheels 1, 2, once any of the rollers 10, 21 is damaged, the user must scrap and discard the entire universal wheels 1, 2, and must purchase new universal wheels 1, 2 In order to complete the maintenance work of the vehicle, the user not only cannot quickly disassemble the universal wheels 1, 2, but also cannot only purchase parts such as the rollers 10, 21 to replace the damaged rollers 10, 21, which not only causes waste of resources, Significantly increased maintenance costs

Not only that, because the parts of the known universal wheels 1 and 2 are not independent, so the manufacturer cannot produce and sell parts of different specifications according to various demands when producing the universal wheels 1 and 2, which not only increases the Increased production costs, greatly increased the inventory pressure of parts, and the space required to store parts, resulting in unsatisfactory use effects
