Description
M G, что обеспечивает совместный поворот обопх полушкпвов 2 и 3 отпоснтельпо ведомого вала 1. На подвижном полушкнве 3 закреплен осиоваппем большого диаметра хвостовик 7, выполпеииый в виде тела вращени неременного диаметра вдоль оси симметрии с винтовым пазом с посто нным углом подъема винтовой линии, с которым взаимодействуют ролики 5. Подвижный полушкив 3 нодпружинен пружиной 8 сжати .MG, which provides a joint rotation of the half-sleeves 2 and 3 of the open shaft of the driven shaft 1. On the moving half of the shaft 3, an axis of a large diameter is attached to the shank 7, which turns out to be a body of rotation of irregular diameter along the axis of symmetry with a helical groove with a constant elevation angle of the helical line the rollers 5 interact. The movable sheath 3 is spring loaded by a spring 8 of compression.
Передача работает следующим образом.The transmission works as follows.
При увеличении момента сил сопротивлени увеличиваетс сила, с которой пальцы 4 с роликами 5 дав т на винтовой паз хвостовика 7, при этом создаетс осевое усилие , которое превосходит осевое усилие, создаваемое ремнем, вследствие чего подвижный полушкив 3 начинает перемещатьс в осевом направлении, т. е. уменьшаетс рассто ние между шкивами и увеличиваетс передаточное отношение вариатора. Изменение передаточного отношени - вариатора происходит до тех нор, пока не установитс равенство созданного осевого усили и осевого усили , создаваемого ремием .As the moment of resistance forces increases, the force with which the fingers 4 with the rollers 5 press against the screw groove of the shank 7 increases, an axial force is created that exceeds the axial force generated by the belt, as a result of which the movable sheath 3 begins to move in the axial direction, t. that is, the distance between the pulleys is reduced and the variator gear ratio is increased. The change of the gear ratio - the variator occurs until the equality of the created axial force and the axial force created by the remy is established.
В процессе регулировани происходит поворот нолушкивов 2 и 3 относительно вала 1.In the process of regulation, the rotation of the nolushkiv 2 and 3 relative to the shaft 1.
Предлагаемое устройство обеспечиваетThe proposed device provides
носто нный КПД, чувствительность регулировани на всем диапазоне изменени передаточного отношени и носто нство коэффициента т ги, за счет выбора максимальной величины которого можно снизить нагрузку на ремень и тем самьтм увеличить его долговечность.efficiency, control sensitivity over the entire range of the gear ratio and the efficiency of the thrust coefficient, by choosing the maximum value of which you can reduce the load on the belt and thereby increase its durability.
