Referring to fig. 1 and 2, an embodiment of the invention provides an omni wheel 100. The omni wheel 100 includes a hub 10 and a plurality of driven wheels 20. The driven wheels 20 are rotatably mounted on the hub 10, respectively.

Referring to fig. 3, the hub 10 includes a body 11, a first supporting portion 12 and a second supporting portion 13. The body 11 is substantially cylindrical. The first support portion 12 and the second support portion 13 are provided on the outer periphery of the body 11 in the axial direction of the body 11. The first support portion 12 and the second support portion 13 are respectively provided with a plurality of mounting grooves 14. The mounting grooves 14 are respectively uniformly arranged around the circumferential direction of the body 11, and the mounting grooves 14 of the first supporting part 12 and the second supporting part 13 are staggered with each other.

In some embodiments, four mounting grooves 14 are respectively disposed on the first supporting portion 12 and the second supporting portion 13.

The body 11, the first supporting portion 12 and the second supporting portion 13 are integrally formed.

A driven wheel shaft 15 for mounting a driven wheel 20 is arranged in the mounting groove 14. The driven wheel 20 is rotatably arranged on the driven wheel shaft 15 along a direction perpendicular to the axial direction of the body 11.

The driven axle 15 includes a rotating shaft 151 and a mounting shaft 152 disposed in the mounting groove 14 in an axial direction perpendicular to the body 11 and facing each other. The rotating shaft 151 and the mounting shaft 152 are respectively used for mounting one side of the driven wheel 20 so as to mount the driven wheel 20 in the mounting groove 14.

The rotating shaft 151 has a substantially cylindrical shape.

An installation surface 1521 is disposed at one end of the installation shaft 152 near the rotation shaft 151. The mounting surface 1521 is inclined outwardly of the mounting slot 14 to facilitate mounting of the driven wheel 20.

The driven wheel 20 includes a driven roller 21 and a coating layer 22. Driven holes 210 are respectively formed at two ends of the driven roller 21. The driven holes 210 are provided in the rotating shaft 151 and the mounting shaft 152, respectively, to mount the driven roller 21 to the driven-wheel shaft 15. The coating layer 22 is sleeved on the outer side of the driven roller 21.
