Abstract
In known combinations of a planetary gear transmission with a continuously variable friction drive transmission, unsatisfactory accuracy in operation and excessive overall dimensions are found to be disadvantageous. The transmission according to the invention comprises a planetary gear transmission (11) operatively connected to a continuously variable friction drive transmission (12) with spherical rolling members (19). The transmission according to the invention is finely or infinitesimally adjustable over a wide range of positive or negative transmission ratios and particularly suitable for employ in a closed control system.
Claims8
A transmission comprising:
- an input shaft;
- an ouput shaft;
- a continuously variable friction drive trnasmission (12) including an input component (7), an output component (2) and spherical rolling members (19), with said input shaft (1) being operatively connected for transmitting torque to both said planet carrier (3) and said input component (7), and said output component (2) being oepatively connected to said sun gear (4) and said outer gear (5) being operatively connected to said output shaft (6).
