ANGULAR VARIABLE-SPEED DRIVE Russian patent published in 1994 - IPC

Abstract RU 2020330 C1

FIELD: stepless control of angular speed of machine working shafts, based on changing the diameters of sheaves. SUBSTANCE: drive sheaves have the form of discs with spiral grooves on their end surface. Sectors move radially over said grooves. This increases or reduces the sheave diameter, correspondingly. Variable-speed drive is controlled by auxiliary reversible electric motors. EFFECT: improved design. 5 dwg
