Definitions

  • the main object of this invention is to provide a UNIFORM and STEADY output, when the input is uniform and steady, with the ability to transmit high torque without depending on friction or friction factor.
  • Many of the continuous variable transmissions that is in the market today are friction dependent therefor lacks the ability to transmit high torque.
  • Those continuous variable transmissions, which are non-friction dependent does not have a uniform and steady output when the input is uniform and steady.
  • This design aids reduction in the overall size and economically mass produced.
  • This design can be easily integrated into any system. This design is very versatile and can be used ranging from light duty to heavy duty. This design allows replacement of existing regular transmission, requiring very little modification. This design offers the option of stationary co-axial input and output.
