PLANETARY GEAR (DESIGN VERSIONS) Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: solids of revolution are made in form of similar rings. Rings are pressed from inside to crank by rollers. Rings are gripped from outside by fixed cam whose profile is made to periodic function expressing increment of its radius depending on gear ratio and depending on crank eccentricity value with account of continuous kinematic coupling of all interacting members. Rollers are arranged simultaneously in radial holes of carrier and are rigidly secured on bearing member. Bearing member is freely fitted in housing for rotation and plane-parallel displacement over radius within the limits of crank eccentricity. Diameters of carrier holes are greater than roller diameter by values of two eccentricities. EFFECT: increased efficiency and enlarged operating capabilities. 3 cl, 9 dwg
