TRANSMISSION WITH INTERMEDIATE MEMBERS Russian patent published in 2008 - IPC F16H1/00 F16H25/06 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in drives of high accuracy machines and mechanisms. Proposed transmission contains input shaft 1 with eccentric disks 3 displaced relative to central axis through value "e". Twin cam 6 with two separated cycloidal surfaces is installed on disk on antifriction bearings. Roller intermediate solids 9 are arranged in two rows over circumference in independent cages. Transmission contains also two wheels 12, 13 with cycloidal surfaces. One wheel 12 is fixed in transmission housing 16. Other wheel 13 is rigidly secured on output shaft 2. Cycloidal profile of each wheel is in contact with its row of roller intermediate solids which are simultaneously in contact with cycloidal profile of cam. Output shaft 2 with wheel 13 is installed on two spaced rolling supports 17, 18. Number of cycloidal profiles of wheel differs by two from number of cycloidal profiles of cam in constant contact through row of roller intermediate solids. Number of roller intermediate solids differs by one from number of cycloidal profiles.

EFFECT: increased service life of transmission and gear ratio.
