Embodiment Construction

[0012] The present invention is described in further detail below in conjunction with accompanying drawing:

[0013] Such as figure 1 As shown, the magnetic powder torquer includes: a coil 1, a yoke 2, a magnetic powder 3, a rotor 4, a bearing 6, and an output bushing 7. The coil 1 is installed in the coil groove of the annular yoke 2, and the rotor 4 is arranged in the two magnets. In the middle hole of the yoke 2, the mating surface of the rotor 4 and the yoke 2 is V-shaped or arc-shaped, and the distance between the mating surfaces of the rotor 4 and the yoke 2 is 0.5mm~1.0mm. 2 depends on the size of the mating surface. There are annular grooves 5 evenly distributed on the mating surface of the rotor 4, and the V-shaped arc-shaped mating surface between the rotor 4 and the yoke 2 is filled with magnetic powder 3, and the magnetic powder is selected from 100 mesh to 250 mesh. The output shaft sleeve 7 is connected coaxially, and the outer ring of the bearing 6 is connect...

Abstract

The invention relates to a magnetic powder power twister special for a resistance source of fitness equipment, and belongs to the technical field of fitness equipment. The magnetic powder power twister is formed by improving a magnetic powder brake, a magnet yoke and a rotor working face in the magnetic powder brake are optimized, an original rectangular working face is changed into a V-shaped or arc-shaped working face, therefore, the working area of the magnetic powder power twister is increased, the working torque is increased, under an electronic control system, the size of a magnetic field is adjusted by changing the current in a coil, it is guaranteed that the magnetic powder power twister rotates at will under the low-speed state, and normally works in the intermittent movement state, and the aims of adjusting the torque at will by a user and conducting strength exercise are achieved. Man-machine coupling is truly achieved. The magnetic powder power twister is reasonable in structure, safe in use and suitable for the fitness equipment of various types and strength equipment special for exercise training.

Description

technical field [0001] The invention relates to a special magnetic powder torquer for resistance sources of fitness equipment, which belongs to the technical field of fitness equipment. Background technique [0002] In view of the traditional weight source of fitness equipment adopting the method of superimposed weight iron, people introduce magnetic powder brakes into fitness equipment, change the linear motion of the traditional weight source of fitness equipment into rotational motion, and overcome the force of gravity. The linear force changes to a torsional force that overcomes the torque. The method solves the problems of large size, heavy weight, high cost, high noise and poor safety of strength fitness equipment. [0003] In order to solve the above problems, the Chinese Patent Publication No. CN201791309V Publication Date 20110413 is titled "A Resistance Source of Strength Equipment", which uses a magnetic powder brake and a transmission mechanism as a resistance s...
