Abstract
The present invention relates to a kind of body-building apparatus magnetic powder power twister special for resistance source, belong to body-building apparatus technical field.Magnetic power twister of the present invention improves magnetic powder brake, yoke in magnetic powder brake and rotor peripheral face are optimized, change former rectangle working face into V-arrangement or curved working face, thus increase the work area of magnetic power twister, add operation torque, under electronic control system, adjusted the size in magnetic field by the electric current changed in coil, ensure that magnetic power twister rotates arbitrarily under lower-speed state, normal work in intermittent movement state.User can be reached and arbitrarily adjust torsion, realize the object that strength is taken exercise, really achieve man-machine coupling.The present invention is rational in infrastructure, use safety, is applicable to various forms of body-building apparatus and training specific strength equipment.
Description
Technical field
The present invention relates to a kind of body-building apparatus magnetic powder power twister special for resistance source, belong to body-building apparatus technical field.
Background technology
The mode of superposing type balance weight iron is all adopted for traditional physical-strength-type fitness facility counterweight source, magnetic powder brake refers in body-building apparatus by people, the rectilinear motion in traditional counterweight of body-building apparatus source is changed over rotary motion, the straight line force overcoming gravity is changed into the twisting resistance overcoming moment of torsion.With this solution physical-strength-type fitness facility volume is large, Heavy Weight, cost are high, noise is large, the problem of poor stability.
In order to solve the problem, China Patent Publication No. CN201791309V publication date 20110413 denomination of invention be " a kind of resistance source for strength equipment ", this invention adopts magnetic powder brake and transmission mechanism as sources of resistance.Magnetic powder brake industrially uses usually, controls output torque realize rotary resistance by filling magnetic in the working clearance face between rotor and yoke.But the duty of industrial magnetic powder brake is the rotary motion of even acceleration and even deceleration, and the movement characteristic of body-building apparatus is batch (-type) and low-speed rotation.Direct employing magnetic powder brake, on body-building apparatus, particularly can produce rotation work state labile in low speed, intermittent movement, and sporter feels that resistance fluctuation is very large, directly has influence on the inherently safe of body-building effect and user.
Summary of the invention
For above-mentioned Problems existing, the object of the present invention is to provide the body-building apparatus magnetic powder power twister special for resistance source of a kind of low noise, safety, stable working state.
To achieve these goals, its technical solution is:
A kind of body-building apparatus magnetic powder power twister special for resistance source, comprise magnetic powder brake coil, yoke, magnetic, rotor, bearing, output sleeve, the V-shaped shape of mating surface of described rotor and yoke or arc shape, the mating surface of rotor is evenly distributed with annular groove, in the V-arrangement between rotor and yoke or arc mating surface lacuna, fills magnetic.
Spacing between described rotor and the mating surface of yoke is 0.5mm ~ 1.0mm.
Adopt above technical scheme, magnetic power twister of the present invention improves magnetic powder brake, yoke in magnetic powder brake and rotor peripheral face are optimized, change former rectangle working face into V-arrangement or arc shape working face, thus increase magnetic work area, add operation torque, under electronic control system, adjusted the power of working face magnetic chain by the size of current changed in coil, ensure that magnetic power twister rotates arbitrarily and normal work in intermittent movement state under lower-speed state.Can reach and arbitrarily adjust torsion, reach the object realizing strength and take exercise, really achieve man-machine coupling.
The present invention is rational in infrastructure, use safety, is applicable to various forms of body-building apparatus and training specific strength equipment.
accompanying drawing illustrates:
Fig. 1 is a kind of structural representation of body-building apparatus magnetic powder power twister special for resistance source.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figure 1, magnetic power twister comprises: coil 1, yoke 2, magnetic 3, rotor 4, bearing 6, output sleeve 7, described coil 1 is arranged in the yoke 2 coil cell body of annular, rotor 4 is arranged in two yoke 2 interstitial holes, the mating surface forming V-shape shape of rotor 4 and yoke 2 or arc shape, spacing between the mating surface of rotor 4 and yoke 2 is 0.5mm ~ 1.0mm, and spacing coordinates size along with the mating surface of rotor 4 and yoke 2 and determines.The mating surface of rotor 4 is evenly distributed with annular groove 5, magnetic 3 is filled in V-arrangement arc mating surface between rotor 4 and yoke 2, magnetic selects 100 order ~ 250 orders, and rotor 4, bearing 6 inner ring are connected with output sleeve 7 coaxial cooperation, and bearing 6 outer ring is done coaxial cooperation with yoke 2 and is connected.
During use, the output sleeve 7 of magnetic power twister connects the transmission mechanism of body-building apparatus, makes it output sleeve 7 rotor driven 4 and rotates in yoke 2, and coil 1 is energized and produces magnetic field, and the magnetic 3 between rotor 4 and yoke 2 produces magnetic chain, thus produces frictional force.By increasing the electric current in magnetic power twister coil 1, the magnetic chain of magnetic 3 is strengthened, thus the frictional force between the yoke 2 produced and rotor 4 makes it the moment of torsion that rotor 4 rotates increases thereupon, otherwise by weakening the electric current in magnetic power twister coil 1, magnetic 3 magnetic chain weakens, thus the moment of torsion formed also can reduce.Because the yoke 2 in magnetic power twister and rotor 4 working face are V-arrangement shape or arc shape, magnetic is more easily gathered on working face, substep evenly, the working face between yoke 2 and rotor 4 is just added after making V-arrangement or arcwall face into, thus increase magnetic 3 work area, add operation torque, fully ensure that magnetic power twister low speed rotates arbitrarily and normal work in intermittent movement state.
Claims (2)
