Overview of continues variable transmission design
Fryčar, Michal ; Dočkal, Kryštof (referee) ; Šperka, Petr (advisor)
Friction variators are used in many industries mainly for their ability to continuously change the engine-to-output gear ratio while machine is running. In this paper, six types of construction were described (using a belt, chain, ball or toroidal, conical and disc wheel). Their properties were then compared based on the maximum transmitted power and transmission efficiency. The results calculated using Hertz's theories shows, that belt, chain and toroidal constructions are transmitting the highest amount of maximum torque. These results are in accordance to earlier studies in this field and they are intended to serve as a source of information for further research on topic.
