PLANETARY REDUCTION GEAR Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: inner part of housing is provided with three mounting holes: first hole is used for receiving the crown wheel and second and third holes are used for mounting the low-speed shaft in rolling-contact bearings. Sun gear wheel is secured in inner cylindrical bore of low-speed shaft at the end. End portion of low-speed shaft is made in form of bowl with axle secured in its bottom. One end rolling-contact bearing of carrier with satellites is mounted on this axle. Other rolling-contact bearing is received by inner bore at end of housing. Drive shaft is mounted inside carrier on rolling-contact bearings without fastening screws and flange caps. Carrier is made in form of individual assembly unit articulated with other members of mechanism by means of flange of housing through rolling-contact bearing of carrier. EFFECT: enhanced reliability and kinematic accuracy; compactness of reduction gear. 1 dwg
