TURBINE DAMPING DEVICE

摘要

A turbine damping device is mounted on a fitness device, and has a housing assembly, a turbine assembly, and a regulating unit. The turbine assembly is mounted inside the housing assembly and has a turbo casing, a turbo wheel, and an adjusting plate. The turbo casing has an exhaling hole. The adjusting plate is controlled by the regulating unit and mounted movably in the exhaling hole. The turbo wheel is mounted rotatably inside the turbo casing. The turbo casing and the turbo wheel generate an airflow resistance that is an exercising load for users using the fitness device. The adjusting plate regulates an opening size of the exhaling hole to adjust the airflow resistance. The turbine damping device has a simple structure and maintenance thereof is easy. A user adjusts the exercising load easily by controlling the adjusting plate. The fitness device with airflow resistance is helpful to environmental protections.
