Abstract

FIELD: mechanical engineering. SUBSTANCE: variable-speed drive has drive pulley 1 and driven pulley 4 interconnected through endless flexible coupling 3. Conical surface of pulleys 1 and 4 is composed of movable plates 6 mounted within guiding slots 7 in pulley cheeks 8. Recess 9 in inner side of each plate 6 is adapted to receive base of hollow cone of actuating link 11. Axial movement and fixation of actuating link 11 are effectuated by command. Pairs of retaining rollers 12 are disposed adjacent to each pulley, one at larger end and one at smaller end of pulleys. As a result friction between endless flexible coupling and conical surface of pulleys 1,4 is reduced, when transmission ratio of variable-speed drive is varied. EFFECT: increased efficiency and enhanced reliability in operation. 2 cl, 2 dwg

Изобретение относится к машиностроению, в частности к вариаторам с бесступенчатым изменением частоты вращения ведомого вала. Сущность изобретения заключается в том, что конусная поверхность ведущего шкива 1 и ведомого шкива 4, которые связаны бесконечной гибкой связью 3, состоит из отдельных подвижных пластин 6, пластины 6 установлены в направляющих пазах 7, которые выполнены на щеках 8 шкивов, причем на внутренней стороне каждой из пластин 6 сделан вырез 9, в который входит основание полого конуса исполнительного звена 11, осевое перемещение и последующая фиксация исполнительного звена 11 осуществляется по команде, а фиксирующие ролики 12 установлены попарно у каждого шкива, один - со стороны большего, другой - со стороны его меньшего основания. Достигаемый при этом технический результат заключен в уменьшении трения витков бесконечной гибкой связи 3 о конусную поверхность шкивов 1,4 при изменении передаточного отношения вариатора. 1 п. ф-лы, 2 ил.The invention relates to mechanical engineering, in particular to CVTs with stepless variation of the speed of the driven shaft. The essence of the invention lies in the fact that the conical surface of the driving pulley 1 and the driven pulley 4, which are connected by an endless flexible connection 3, consists of separate movable plates 6, the plates 6 are installed in the guide grooves 7, which are made on the cheeks 8 of the pulleys, and on the inner side each of the plates 6 has a cutout 9, which includes the base of the hollow cone of the actuator 11, axial movement and subsequent fixation of the actuator 11 is carried out by command, and the fixing rollers 12 are installed in pairs for each o pulley, one on the side of the larger, the other on the side of its smaller base. The technical result achieved in this case is to reduce the friction of the turns of the endless flexible connection 3 on the conical surface of the pulleys 1.4 when the gear ratio of the variator changes. 1 p. Fs, 2 ill.
