DRIVE WITH INTERMEDIATE ROLLER LINKS Russian patent published in 2008 - IPC F16H1/32 F16H25/06 

FIELD: precision engineering; precision drives.

SUBSTANCE: invention relates to gear drives used to transmit rotation and it can be used in drives reducing and increasing speed of output shaft of high-precision machines and mechanism. Proposed drive with intermediate roller links has coaxial high-speed shaft 1 and slow-speed shaft 2. Eccentric 3 displaced relative to central axis through value "e" is made on high-speed shaft 1. Antifriction bearing 4 being in mechanical contact with intermediate links 6 is installed on eccentric. Intermediate roller links are placed in holder 7 secured on outer race of bearing 4. intermediate roller links 6 are simultaneously in contact with inner shaped profile of central wheel 8, outer race of bearing 4 and shaped profile of cam 9 rigidly secured on slow-speed shaft 2.

EFFECT: improved reliability of drive by preventing getting of holder under intermediate link.
