Adaption of Continuously Variable Transmissions to the Characteristic of a Driven Machine by Bicoupled Planetary Transmissions

Bicoupled Planetary Transmissions composed of any variable Transmission and a planetary gear can be designed to realize any optional speed ratio range including speed reversal and its output characteristic can be approached to the characteristic of the driven machine in order to obtain an economic overall transmission. The paper describes a standardized method to design and to optimize such transmissions.
