POWER PLANT AND FRICTION TRANSMISSION Russian patent published in 2001 - IPC

FIELD: engine manufacture. SUBSTANCE: given power plant has engine with output shaft and prime mover interconnected by uniaxial planetary transmission with satellites, sun and crown gear wheels. Transmission is frictional with conical working surfaces of satellites, sun and crown gear wheels having common engagement vertex at point on axis of transmission located along path of prime mover. Friction transmission of power plant includes sun gear wheel, springy crown gear wheel and satellites interference fitted on it. Crown gear wheel is linked to web of wheel or to body with the aid of flexible member. EFFECT: automatic measurement of pressure force between transmission gear wheels proportional to variations of thrust of engine and to clear level of misalignment of working surface of crown gear wheel when it is attached to web of wheel or anchored in body. 9 cl, 6 dwg
