Problems solved by technology

Since the small rollers use hard rubber, as the contact points switch between the two rows of small rollers, the contact impact between the small rollers and the ground will be relatively large, resulting in relatively large noise and bumps, and may also be on the ground. leave marks on

Embodiment Construction

[0021] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] See figure 1 , figure 2 , image 3 , Figure 4 , A double-row omnidirectional wheel of the present invention is composed of a hub 1, an omnidirectional wheel fixing block B, an omnidirectional wheel fixing block A, and an omnidirectional wheel roller assembly 4, wherein the omnidirectional wheel roller assembly 4 includes a small roller 5. Two small roller bearings 6, two spacer blocks 7 and omnidirectional wheel pins 8. The small roller 5 is composed of external soft rubber wrapped with internal hard rubber. The rim of the small roller 5 is curved, and the two small roller bearings 6 Located on the inner sides of the two ends of the small roller 5, the small roller bearing 6 is composed of an inner ring and an outer ring. The inner ring is sleeved on the omnidirectional wheel pin 8, and the outer ring is clamped with the hard...

Abstract

The invention relates to a double-rowed universal wheel. The universal wheel is composed of a wheel hub 1, a universal wheel rolling wheel assembly 4 and a universal wheel fixing block, wherein the rolling wheel assembly is also composed of a small rolling wheel 5, small rolling wheel bearings 6, a universal wheel pin 8 and a cushion block 7; one small rolling wheel bearing 6 is pressed into the inner side of each of the two ends of the small rolling wheel 5; the small rolling wheel bearings 6 sleeve the universal wheel pin 8; an outer ring is clamped into hard rubber in the small rolling wheel 5; the outer side of a bearing inner ring also ejects against the cushion block 7 which sleeves the universal wheel pin 8; the two ends of the universal wheel pin 8 are fixedly arranged on the wheel hub 1 and are locked by a self-tapping screw and a stopping block. The double-rowed universal wheel provided by the invention can rotate around the wheel hub and the small rolling wheel can also rotate around a self wheel shaft, so that the universal wheel can roll from front to back and can also slide along the lateral direction. Compared with existing other double-rowed universal wheels, the universal wheel has the advantages that noises are greatly reduced, a jolting phenomenon is reduced, the rolling performance is improved and the service life is prolonged; the universal wheel is convenient to mount and dismount.

Description

Technical field [0001] The invention belongs to the technical field of industrial robots and the automotive field, and specifically relates to a double-row omnidirectional wheel. Background technique [0002] At present, my country is vigorously promoting the development of the robot industry, and because of its own advantages that the omni wheel can roll forward and backward at the same time, its application in some special vehicles and robots driven by the bottom wheel system is becoming more and more popular. [0003] The current double-row omnidirectional wheels are mostly composed of two sets of single-row omnidirectional wheels, and the single-row omnidirectional wheels are composed of two plate-shaped hubs sandwiching all the wheel pins of the single-row omnidirectional wheels. Put the copper sleeve on the inner side of the small roller and insert the wheel pin directly. After the single-row wheel hub is fixed by short bolts and nuts, the two rows of omnidirectional wheels ...
