Design and Simulation on Hand Skipping Rope Equipment

Hand skipping rope equipment is developed with braking trundles which can count. With the help of trundles people can move the machine to a right place. The right and left circle diameter are 2100mm. Distance of the two circles can be changed. Mechanical counter is installed on the handle. Turns can be moved to the left circle and the drive shaft by the counting handle. Meanwhile the counter begins to count. The shaft move turns from the chain to right circle. Four identical chain wheels are designed, the right and left circle can drive rope rotate at the same time. When the speed is 0. 5r/s, centrifugal force of rope is 12. 26N. When the acceleration was set with 3 valve the simulation shows the acting force of revolving axle is 64N, 11. 8N, 23N, which is similar with calculation.
