ROTOR DRIVE REDUCER FOR LICORICE EXTRACTION MACHINE Russian patent published in 2000 - IPC

FIELD: agriculture. SUBSTANCE: reducer has output shaft 4, pair of oppositely arranged cone gears 33, 34. Both gears are continuously meshed with similar cone gears 35, 36 mounted on cantilevered parts of input and intermediate shafts 2, 3 of reducer. Output shaft 4 is equipped with two opposite output shanks 23, 24. Output shaft 4 is mounted in casing 1 of reducer in position perpendicular to output shaft 2. The latter has movable unit composed of three cylindrical gears 9, 10, 11 which are mounted for alternative engagement with two gears 17, 18 on intermediate shaft 3 and built-in cylindrical gear 38 with inner engagement in cone gear 35 on cantilevered part of input shaft 2. Such construction allows torque to be divided into two currents, when torque variation stage number is increased. EFFECT: simplified construction and increased efficiency. 3 cl, 1 dwg
