AUTOMATIC STEPLESS GEARING Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: gearing contains housing 1, driving 2 and driven 3 shafts, carrier 6 with radial axles 7 whereon basic and additional 10 intermediate wheels are placed. The basic intermediate wheels consist of coaxially interconnected internal 8 and external 9 angular wheels engaged with driving wheel 4 mounted on the driving shaft and driven wheel 5 mounted on the driven shaft. The additional intermediate wheels engage central supporting wheel 11 mounted at the end of hollow countershaft 12 placed coaxially to the driving shaft. The countershaft is connected to the driven shaft by means of three driving wheels engaged in series. Driving wheel 13 is mounted on the driving shaft, driving wheel 14 is mounted on the countershaft, and driving wheel 15 is mounted on the supporting axle 16 and is an intermediate one between the first and second wheels. The supporting axle is placed outside of the 0-0 axis of the gearing . The carrier is mounted on the driven shaft for independent rotation. EFFECT: expanded range of automatic stepless control of the power value of train between the driving and driven shafts in dependence on the load of the driven shaft. 10 cl, 2 dwg
