PLANETARY REDUCER (VERSIONS) Russian patent published in 2010 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: planetary reducer contains casing, in which there are installed high speed and low-speed shafts (12, 13). Group of rollers (18) is installed in corresponding openings on circle of side cover (8) of casing. In disc (14) there are located rollers (24), equally located by circle with centre on axis (11) of low-speed shaft (13). On eccentric (16) it is put link, connecting rollers (18, 24) which is implemented in the form of disc (19) and rollers (21, 22). Difference of amount of cached to each other rollers (18, 22) it is selected equal to two units. Difference of amount of cached to each other rollers (21, 24) it is selected equal to two units. Reference circles on which there are located rollers (21, 24) allow internal touch. Reference circles on which there are located rollers (18, 22) in gear of rollers are not touch to each other. It is proposed version of reducer which has one pair of reference circles of rollers allows internal contact, and the other couple of circles is intersected.

EFFECT: invention provides increasing of value of transmission ratios, simplification of structure ensured b application of standard diametres of rollers, increasing of coefficient of efficiency ensured by reduction of radial force, influencing to reducer bearing.
