Detailed Description

In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.

Example 1:

as shown in fig. 1-2, the embodiment of the utility model provides a pair of novel magnetic resistance rim plate, including axle center 1, planetary gear set and magnetic force rolling disc 3, axle center 1 drives planetary gear set's planet carrier 2 rotates, even array a plurality of planet wheel 4 on the planet carrier 2, planet wheel 4 and the ring gear 5 meshing in the outside, planet wheel 4 and inboard sun gear 6 meshing, sun gear 6 drives magnetic force rolling disc 3 and rotates, and magnetic force rolling disc 3 includes rolling disc 31 and inlays the aluminium strip piece 32 on rolling disc 31 surface.

The structure of the body building equipment is that an axis 1 is a power input shaft, an unidirectional bearing 7 is sleeved on the axis 1, a planetary carrier 2 of the unidirectional bearing 7 is sleeved on the planetary carrier 2 to drive the planetary carrier 2 to rotate, a plurality of planetary wheels 4 are uniformly arrayed on the planetary carrier 2, the planetary wheels 4 are meshed with an outer side gear ring 5, an outer side of the gear ring 5 is sleeved with a gear ring fixing disc 8, the gear ring fixing disc 8 is used for being fixed on a frame of the body building equipment, the gear ring fixing disc 8 is rotationally connected with the planetary carrier 2 through a first bearing 9, the planetary wheels 4 are meshed with an inner side sun wheel 6, one end of the sun wheel 6 is in threaded connection with a magnetic rotating disc 3 to drive the magnetic rotating disc to rotate, the sun wheel 6 is rotationally connected with the axis 1 through a second bearing 10, the outer side of the magnetic rotating disc 3 is sleeved with a fixing disc 11, and, the fixed disc 11 is rotatably connected with the magnetic rotating disc 3 through a third bearing 12.

The planet wheel 4 is matched with the sun wheel 6 and the gear ring 5 in a bevel gear mode, the bevel gear is not easy to damage teeth, the service life of the whole mechanism can be prolonged, in addition, the meshing contact area between the helical teeth is larger, the gap between the helical teeth is smaller, and the torque transmission energy loss is smaller.
