Heavy-load low-vibration all-dimensional wheel

Abstract

A heavy-load low-vibration all-dimensional wheel is characterized in that the all-dimensional wheel comprises two hubs (1) fixedly connected through a connecting sleeve (3), eight rolling wheels (2) are arranged between the two hubs (1), all the rolling wheels (2) are evenly distributed on the circumferences of the hubs (1), a 45-degree included angle is formed between the axis of each hub (1) and the axis L of each corresponding rolling wheel (2), a face perpendicular to the axes of the hubs (1) is a projection face, orthographic projections of the outer contours of the eight rolling wheels (2) on the projection face form a complete perfect circle D, each rolling wheel (2) comprises a rolling wheel body (5), a rolling wheel shaft (4) is sleeved with the rolling wheel bodies (5) in a connected mode, the rolling wheel shaft and the rolling wheel bodies (5) are connected through sliding bearings (6) and thrust bearings (7), the thrust bearings (7) are located at the two ends of the rolling wheel shaft (4), and the sliding bearings (6) make contact with the thrust bearings (7). The heavy-load low-vibration all-dimensional wheel is an all-dimensional wheel which can reduce vibration to the greatest extent in the using process, and has the high bearing capacity.

Description

technical field [0001] The invention relates to a wheel structure, in particular to a heavy-duty low-vibration omni-directional wheel. Background technique [0002] Due to its special structure, the omnidirectional wheel can realize movement modes such as forward movement, lateral movement, oblique movement, rotation and combinations thereof. Mobile devices such as forklifts or transport platforms equipped with all-round wheels are very suitable for environments with limited transfer space and narrow working passages, so they have been widely used in industrial production. However, there are still some problems with the traditional omni-directional wheel: first, because the projection of the outer contour of the roller on the side of the hub is not a complete circle, it will generate large vibration during operation; second, the internal structure of the roller is limited. The overall bearing capacity of the omnidirectional wheel is affected, and its application range is li...
