Problems solved by technology
[0004] However, the current methods of transportation based on spherical surfaces are mainly concentrated on ordinary wheeled and crawler-type. Obviously, the above two methods have the following disadvantages or shortcomings: large turning radius, low space utilization, poor movement flexibility, and low transfer efficiency
However, if the existing mobile platform based on plane mecanum wheels is used, there are two problems: 1) only a part of the roller is always in contact with the spherical crown during the movement of the trolley; 2) the transition from one roller to the other during operation a roller jumps from time to time

Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.
[0034] Such as figure 1 As shown, the present invention provides a mecanum wheel based on the surface of the spherical crown, which is designed based on the theory of the mecanum wheel on the spherical surface and the reconceived theoretical model of the drum-shaped conical table. The mecanum wheel includes a central axis 1. Support plate 2, roller shaft 3, and roller 4. The mecanum wheel has a...

The invention discloses a Mecanum wheel based on a spherical crown surface. The Mecanum wheel is of a drum-shaped boss structure integrally, the side face of the drum-shaped boss structure is in line contact with the spherical crown surface, the Mecanum wheel comprises a central shaft, supporting plates, a roller shaft and a roller, the supporting plates are mounted on two sides of the central shaft respectively and form an upper undersurface and a lower undersurface of the drum-shaped boss structure, each supporting plate is round, multiple supporting holes used for supporting the roller shaft, extending to the outside of the supporting plate and arranged obliquely relative to the central shaft are uniformly distributed in the edge of each supporting plate, the supporting holes corresponding to the supporting plates on two sides of the central shaft are coaxial, and the roller is mounted on the roller shaft and is in line contact with the spherical crown surface. The Mecanum wheel can realize good line contact with the spherical crown surface, avoids jumping of the roller in the process of switching and has a high-accuracy omnibearing movement function.
Description
technical field [0001] The invention belongs to the field of mecanum wheel design, and more specifically relates to a mecanum wheel based on a spherical crown surface. Background technique [0002] For the working environment with limited carrying space and narrow passages, driving and transferring equipment composed of ordinary wheels and corresponding steering systems are usually used for carrying, which has many problems such as large turning radius, low space utilization rate, poor movement flexibility, and low transfer efficiency. Unfavorable factors have seriously affected the efficiency of the material support system. With the development of omnidirectional movement technology, especially the maturity of omnidirectional movement technology based on mecanum wheel, this problem has been effectively solved. The omnidirectional motion platform using this technology can generate omnidirectional motion with 3 degrees of freedom, and can reach the target location along any ...
