Embodiment 1

[0021] according to Figure 1 to Figure 6 , the hub of the omnidirectional wheel, including the hub main body 1 and the roller support frame 2, the roller support frame 2 is connected with the hub main body 1 through grooves 24 and screws, and is evenly distributed and fixed on the outer circle of the hub main body 1. The bottom plate 21 of the roller support frame 2 is arc-shaped, which matches the shape of the roller wheel. Two support arms 22 are vertically arranged on both sides of the bottom plate 21. The support arms 22 are provided with shaft holes 23, and the shaft holes 23 cooperate with the roller shafts. For installation, a bottom groove 25 is arranged below the bottom plate 21, and ribs 26 are arranged on both sides of the bottom groove 25. The outer circumference of the hub main body 1 is evenly provided with an installation chute 11, the direction of the installation chute 11 and the bottom groove 25 are consistent, and the bottom surface 110 of the installation ...

Embodiment 2

[0023] According to attached figure 1 to attach Figure 6 , The main body of the hub 1 is processed by copper-aluminum alloy, and local heat treatment is carried out to improve the strength. Eight roller support frames 2 are evenly distributed on the outer circumference of the hub main body 1, and each roller support frame 2 is processed with a shaft hole 23 for installing the roller shaft. The angle between the roller installation and the hub shaft is 45 degrees, so that the When the wheel rotates at any angle, the force is uniform. There are positioning holes in the inner side of the hub main body 1, so that it can be closely installed with the motor reducer and fastened by bolts. The inner side of the hub main body 1 is a mounting surface, and the outer side is provided with reinforcing ribs, thereby reducing the weight of the hub and improving its strength and toughness. The intersection points of the roller support frame 2 and the middle section of the hub are evenly d...

Abstract

The invention relates to an omni-directional wheel, in particular to a hub of the omni-directional wheel. The hub of the omni-directional wheel comprises a hub body and roller support frames, wherein mounting chutes are uniformly formed on the outer circumference of the hub body; an included angle is formed between the directions of the mounting chutes and a shaft of the hub body, so that the direction of the omni-directional wheel is easy to change and omni-directional movement is realized; a bottom plate of each roller support frame is circular arc-shaped; two support arms are vertically arranged on the two sides of the bottom plate; axial holes are formed on the support arms; a bottom groove is formed below the bottom plate; rib plates are arranged on the two sides of the bottom plate;the mounting chutes are matched with and fixed to the bottom groove; and the roller support frames are uniformly distributed and fixed on the outer circumference of the hub body. According to the technical scheme, roller wheels and rollers are tightly and simply matched with each other and the rollers are uniformly stressed, so that the transmission and the operation of the omni-directional wheelare more stable.

Description

technical field [0001] The invention relates to an omnidirectional wheel, in particular to a hub of an omnidirectional wheel. Background technique [0002] The omnidirectional wheel is a driving device that can move directly in any direction. The omnidirectional wheel is a mechanism that evenly distributes several rollers around the hub. The hub is driven by power transmission. The rollers are installed on the end surface of the hub. Can be turned freely. Omni-directional wheels are the basis for realizing omni-directional walking. At present, in our country, most omni-directional wheels are experimental products with light load and low power, which are mainly used in the research of the motion mechanism of small robots. The roller support frame of the wheel hub generally adopts a single-head intermediate support. Although the structure of the intermediate support is relatively simple, the force is uneven, which easily causes the roller to break and deform. The uneven forc...
