Description

Technical Field

[0001] The utility model relates to the technical field of friction wheels, in particular to an improved friction wheel. Background Art

[0002] When the friction wheel is in use, two cylindrical friction wheels that are pressed against each other are required. A certain positive pressure is generated between the two wheels due to the pressing. When working, when the driving wheel rotates due to the external force, the driving wheel relies on the friction force generated between the two wheels to drive the driven wheel to rotate together, thereby realizing the transmission of motion and power. However, when the existing friction wheel is in use, the friction wheel is easy to wear, so the entire friction wheel needs to be replaced, and the replacement of the entire friction wheel is relatively cumbersome. Therefore, we propose an improved friction wheel to solve the above problem. Utility Model Content
