FIELD: mechanical engineering; transport, machine tools. SUBSTANCE: invention relates to holonomic drives designed for use in objects and systems employing automatic or forced stepless change of speed of rotation of output shaft depending on shaft load at constant or variable speed of input shaft. proposed drive has different and planetary mechanisms, peripheral devices including hydraulic motor 19, hydraulic pump 18 and overrunning clutch 20 and device for connection with peripheral devices and transmission of rotation to input shaft 1. Differential mechanism has sun gear 6, carrier 3 and epicycle 5. planetary mechanism has sun gear 9, carrier 11, paired planet pinions with gear rims 13 and 14 and gear wheel 10. epicycle 5 and gear wheel 10 are connected by hollow shaft 8 freely fitted on output shaft 7 between mechanisms. Transmitting device is made in form of gear wheel 15 secured on carrier 11 and mechanically coupled with wheel designed for rotation of peripheral device and with wheel designed for receiving rotation from peripheral device and meshed with additional wheel installed either on input shaft 1 or on carrier 3. EFFECT: simplified design of drive owing to dispensing with differential mechanism on output shaft, provision of speed of output shaft greater than that of input shaft. 3 cl, 4 dwg |
