Abstract
The invention provides an intelligent electromagnetic fitness equipment damper for replacing the conventional balance weight iron. Because a magnetic powder clutch has the characteristic that the size of the transmission torque has proportional linear relation with the magnetizing current but is not related to the slip frequency speed thereof, the size of the moving resistance is changed by a method of controlling the size of the slip frequency torque generated by the magnetizing current by controlling the magnetizing current. An accelerating mechanism consisting of a planetary gear train increases the rotating speed to reduce the allowable torque transmission value of the used magnetic powder clutch. Input and output ends of the magnetic powder clutch are respectively connected with two gears generating rotating speed difference in a differential mechanism consisting of two gear pairs with different speed ratios to acquire lower slip frequency speed to reduce the slip frequency powder. The intelligent electromagnetic fitness equipment damper changes the linear motion of the balance weight source of the conventional fitness equipment into the rotating motion, carries out real-time detection on the fitness equipment by adopting a computer control system and carries out dynamic management on different requirements on different equipment through program setting.
