Description

Technical Field

[0001] The invention relates to the technical field of wheel structures, and in particular to an asymmetric wheel structure. Background Art

[0002] The asymmetric wheel structure is an innovative design in the field of vehicle technology. It aims to improve the performance and life of the wheel through an asymmetric design. The asymmetric wheel structure solves a number of problems such as abnormal vibration by optimizing and improving the traditional wheel design, thereby extending the service life of the wheel and improving the vehicle's handling. Its unique design enhances the wheel structure strength.

[0003] Rail gnawing is a chronic problem in overhead crane operation, especially for overhead crane wheels using tapered roller bearings. Designers usually need to change the two tapered roller bearings on the inner and outer sides to a single spherical roller bearing and construct a bearing sleeve if they want to change to an automatic deviation-correcting wheel set. Considering the load-bearing capacity, the radial dimension of the spherical roller needs to be increased, which will increase the size of the angular bearing box and cause changes in the wheel center and the original reducer center. Normally, the reducer motor needs to be moved downward a little, but the foundation for the transformation is difficult, the requirements are high, and the construction time is long.

[0004] Therefore, we propose an asymmetric wheel structure. Summary of the invention
