This application provides a resistance transmission device and fitness equipment. The resistance transmission device includes: a drive source, a
reducer, a rotating shaft, an inner cylinder, and a
rope winding drum. Torque is provided by rotating the output shaft of the drive source. The
reducer includes a
reducer housing and an input end and an output end located at both ends of the reducer housing. The input end is connected to the output shaft of the drive source. The rotating shaft is synchronously connected to the output end of the reducer. The inner cylinder is sleeved outside the reducer housing and fixedly connected to it. The outer circumference of the
rope winding drum is used to wind the pull
rope. The rope winding drum rotates synchronously with the rotating shaft and can slide along the axial direction of the rotating shaft. The rope winding drum is sleeved outside the inner cylinder, and the inner surface of the rope winding drum and the outer surface of the inner cylinder are in
helical drive engagement. By optimizing the pull rope winding structure, the pull rope is wound and unwound in an orderly manner. Combined with the reducer, this increases the output resistance, which is beneficial for improving training effectiveness.
