Abstract: A rotating resistance device, including a main shaft and a damping assembly; a rotating wheel is mounted on the main shaft; a damping wheel is rotatably arranged, and a surface of the fixed disc is cooperated with the damping wheel; a damping adhesive is arranged between the damping wheel and the surface of the fixed disc; a scraping component is provided on the damping wheel; the rotating wheel is connected to the damping assembly and configured to adjust a number of the damping units linked to the rotating wheel. The adjustment of the resistance value follows a stepwise change, and the adjustment precision is very high, allowing for precise tuning to the desired resistance value based on actual needs. Moreover, after long-term use, the resistance value remains largely stable without significant degradation, and there is no thermal fatigue, eliminating the need for heat dissipation.
