  • Variable speed changing gear
    Patent number: 5577975
    Abstract: A variable speed changing gear has an internal friction wheel made of elastic material and a cycloid wheel inscribed to the internal friction wheel. The cycloid wheel is rotated for circulating along the internal friction wheel. Because of the elastic material, the effective radius of the internal friction wheel is changeable by giving force to the cycloid wheel in the radial direction. The circulation speed of the cycloid wheel is changed in reverse proportion to the radius. The output shaft can be rotated with variable speed following to the circulation of the cycloid wheel. This speed changing gear can be operated as a load compensating device.
