Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

Example 1

As shown in fig. 1-5, a novel omni wheel comprises a hub 1 and a plurality of rollers 2 mounted on the hub 1, wherein the rollers 2 can freely rotate around their central axes, and the central axes of the rollers 2 are all located in the same plane;

the hub 1 comprises a bearing 101 connected with an axle, a plurality of uniformly distributed fixing frames 102 are fixedly arranged on the outer wall of the outer ring of the bearing 101, the joints of the fixing frames 102 are tightly attached, the outer sides of the fixing frames 102 are fixedly connected through connecting sheets 105, the inner side of the outer part of each fixing frame 102 is fixedly connected with a rotating shaft 103, two sides of the outer part of each fixing frame 102 are fixedly connected with pin shafts 104, and the length of each rotating shaft 103 is greater than the integral length of two adjacent pin shafts 104;

the roller 2 comprises a large roller set 201 and a small roller set 202, the large roller set 201 and the small roller set 202 are the same in quantity, the large roller set 201 and the small roller set 202 are arranged in a staggered mode, a gap is reserved between the large roller set 201 and the small roller set 202, the large roller set 201 is sleeved on the outer wall of two adjacent pin shafts 104, the large roller set 201 is rotatably connected with the pin shafts 104, the small roller set 202 is sleeved on the outer wall of a rotating shaft 103, and the small roller set 202 is rotatably connected with the rotating shaft 103.

The large roller set 201 comprises a large roller inner ring 2011 and a large roller outer ring 2012, wherein the large roller outer ring 2012 is sleeved on the outer wall of the large roller inner ring 2011 and is fixedly connected with the large roller inner ring 2011.

The small roller group 202 comprises a small roller inner ring 2021 and a small roller outer ring 2022, and the small roller outer ring 2022 is sleeved on the outer wall of the small roller inner ring 2021 and is fixedly connected with the small roller inner ring 2021.
