Abstract
The invention discloses a kind of safe high stability fitness equipment resistance system, magnetic powder brake is set, the magnetic yoke of the brake and rotor peripheral face are V-type working face in resistance system.It is additionally provided with returning device, the returning device does not drive magnetic powder torquer to rotate, the reverse torque that dish-type spring is only existed when return utilizes returning device return in fitness equipment return, unilateral bearing, which is in, when after release due to rope roll overturning disengages idling conditions, magnetic powder torquer is not driven to rotate, when return only exists the reverse torque of dish-type spring, so user will not pull in the generation of return stress as traditional type, it is easy to use, reduce inherently safe hidden danger；The magnetic yoke of the brake and rotor peripheral face are curved working face.
Description
Technical field
The present invention relates to a kind of safe high stability fitness equipment resistance systems.
Background technique
Body-building is increasingly valued by people, and traditional physical-strength-type fitness facility counterweight source is all made of superposing type with middle iron
Mode, in return, user due to muscle, joint bear gravity, be easy injury, there are inherently safe hidden danger, return simultaneously
Strong noise can be generated, therefore introduce brake due to mutual shock between clump weight when position, overcoming the straight of gravity
Line power changes into the twisting resistance for overcoming torque, can solve the above problem, but the working condition of magnetic powder brake is to accelerate
With the rotary motion of even deceleration, and the characteristics of fitness equipment it is intermittent and low-speed rotation, directlying adopt brake can make
Equipment rotation work state labile is obtained, resistance fluctuation is big, directly affects body-building effect and user's safety, therefore in order to change
This situation, my company improve in prior art basis, develop safety, high stability fitness equipment resistance system this
One project, to meet domestic market to the higher demand of fitness equipment.
Summary of the invention
The purpose of the present invention is unreasonable for existing Design of Body-Building Equipment, long-time service be easy to cause damage to person
Problem proposes a kind of safe high stability fitness equipment resistance system.
The purpose of the present invention is what is be achieved through the following technical solutions：
Magnetic powder brake, the brake is arranged in resistance system in a kind of safe high stability fitness equipment resistance system
Magnetic yoke and rotor peripheral face be V-type working face.
The resistance system is improved on magnetic powder brake, and the magnetic yoke of brake and rotor peripheral face are optimized, will
Former rectangle working face is changed to V-type or arc shape working face and increases operation torque to increase magnetic powder work area；
Further preferred scheme is to be additionally provided with returning device, and the returning device does not drive magnetic powder torquer to rotate, and is returned
The reverse torque that dish-type spring is only existed when position, in fitness equipment return, using returning device return, due to rope roll after release
Unilateral bearing, which is in, when overturning disengages idling conditions, does not drive magnetic powder torquer to rotate, when return only exists the anti-of dish-type spring
Torque, so user will not pull in the generation of return stress as traditional type, it is easy to use, it is hidden to reduce inherently safe
Suffer from；
Further preferred scheme is that the magnetic yoke of the brake and rotor peripheral face are curved working face.
The present invention has the following advantages compared with prior art：
By structure innovation, the resistance system under electronic control system, by change coil in size of current come
The power of working face magnetic powder chain is adjusted, magnetic powder power twister arbitrarily rotation and intermittent motion state under lower-speed state in guarantee system
In normal work, can achieve any adjustment torsion, achieve the purpose that realize strength take exercise, really realize coupled, mention
The safety that height uses.
Specific embodiment
Magnetic powder brake, the brake is arranged in resistance system in a kind of safe high stability fitness equipment resistance system
Magnetic yoke and rotor peripheral face be V-type working face.It is additionally provided with returning device, the returning device does not drive magnetic powder torquer to turn
Dynamic, when return, only exists the reverse torque of dish-type spring, in fitness equipment return, using returning device return, after release by
Unilateral bearing, which is in, when rope roll overturning disengages idling conditions, does not drive magnetic powder torquer to rotate, when return only exists dish-type bullet
The reverse torque of spring, so user will not pull in the generation of return stress as traditional type, it is easy to use, reduce itself
Security risk；The magnetic yoke of the brake and rotor peripheral face are curved working face.
The resistance system is improved on magnetic powder brake, and the magnetic yoke of brake and rotor peripheral face are optimized, will
Former rectangle working face is changed to V-type or arc shape working face and increases operation torque to increase magnetic powder work area；
The present invention has the following advantages compared with prior art：
By structure innovation, the resistance system under electronic control system, by change coil in size of current come
The power of working face magnetic powder chain is adjusted, magnetic powder power twister arbitrarily rotation and intermittent motion state under lower-speed state in guarantee system
In normal work, can achieve any adjustment torsion, achieve the purpose that realize strength take exercise, really realize coupled, mention
The safety that height uses.
The above examples only illustrate the technical idea of the present invention, and this does not limit the scope of protection of the present invention, all
According to the technical idea provided by the invention, any changes made on the basis of the technical scheme each falls within the scope of the present invention
Within；The technology that the present invention is not directed to can be realized by the prior art.
