PLANET PRECESSION GEAR TRANSMISSION Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: gear transmission has housing and inlet shaft with cranks mounted with inclination to its axis and shifted with respect to each other by 2π/n angle, where n is the number of cranks. The cranks and satellites define the rotation pair. The outer cylindric surface of the satellites is toothed resulting in engaging of the satellites with rollers uniformly arranged inside the cylindric surface of the central wheel. Each of the satellites has a pair of periphery ports. Pins are received in the ports along the precession axis. The pins are also received in the through grooves made in planks rigidly secured to the driven shaft of the gear transmission. EFFECT: improved design. 3 dwg
