  • Patent number: 8414458
    Abstract: A strength training control device comprises: a torque source (including a base frame, a motor and a gear reduction box); and a link mechanism (including a gearbox arm, a first link rod, a second link rod, and an operating rod arm), wherein a S-type load cell is coupled to the first link rod and the second link rod to sense a load value. The control device further comprises: an operating rod, an electronic meter for setting a torque value, and a servo controller for comparing a load value of S-type load cell with a set value of the electronic meter. After the difference value is adjusted, an electric current is outputted to drive the motor, and the motor torque is amplified by the gear reduction box and transmitted through the link mechanism to the operating rod, and users can obtain a torque value equal to the setting of the electronic meter.

  • Publication number: 20090015083
    Abstract: Thread structure for the shaft grounding of an electric motor having a thin thread formed on the surface of the slip ring or the shaft to replace the conventional face contact with the “linear contact” between the surface of the carbon brush and the thread head. During the rotation, the development of friction heat and the oxidation film will be substantially eliminated. Furthermore, the effect of spiral conveyor belt is created when the thread rotates. This can remove the toner, copper powder, etc. produced by friction acting on the surface of the carbon brush and keep a permanent cleanness of the surface of the carbon brush. In this way, a stable contact resistance between the shaft (or the slip ring) and the carbon brush can be maintained and a long-term test shows that the wear of the carbon brush will be further reduced before improvement.
