Title: Mecanum wheel with excellent structural safety
Inventor: KIM DAE YOUNG
IPC: B60B19/12
Filed: 2020-02-06
Abstract: The present invention relates to a Mecanum wheel having excellent structural safety. The Mecanu wheel including a hub to which a small roller connected to the outer periphery is bound and fixed, and a plurality of small rollers formed radially on the outer periphery of the hub and connected obliquely based on a rotation shaft coupled to the hub, further comprises an annular guide roller positioned inside the hub and in close contact with inner surfaces of the plurality of small rollers formed on the hub to support a load applied to the small rollers. According to the present invention, a guide roller capable of supporting the small roller is formed inside the hub to prevent deformation and damage to the small roller due to the load generated on the small roller. Therefore, a service life of the Mecanum wheel can be significantly extended. In addition, through a guide groove formed on the guide roller, it is possible to prevent the small roller from being separated or leaning to one side due to the load, which has an effect of improving structural safety of the Mecanum wheel. Also, the guide roller does not interfere with rotation of the small roller while rotating together with the small roller through a rotating means. Therefore, the smooth rotation of the small roller is induced, and a function of the Mecanum wheel can be guaranteed stably, thereby ensuring versatility of the apparatus.
