Изобретение относитс к передачам дл бесступенчатого регулировани скорости.This invention relates to gears for infinitely variable speed control.
Известен импульсный вариатор марки «ИВА, содержащий ведущий вал, с закрепленным на нем регулируемым эксцентриком, ведомый вал с установленной на нем соосно муфтой свободного хода, передаточное звено, выполненное в виде коромысла, кинематически замыкающее эксцентрик и наружную обойму муфты свободного хода. При равномерном вращении ведущего вала эксцентрик и коромысло привод т в колебательное движение наружнюю обойму муфты свободного хода. С помощью этой муфты колебательное движение преобразуетс в импульсное одностороннее вращение ведомого вала.A pulsed variator of the “IVA” brand containing a drive shaft with an adjustable eccentric fixed on it, a driven shaft with a one-way clutch coaxially mounted on it, a transmission link made in the form of a yoke, a kinematically closing eccentric and an outer race of a one-way clutch are known. With a uniform rotation of the drive shaft, the eccentric and rocker arm oscillate the outer race of the freewheel coupling. With this coupling, the oscillatory motion is converted into a pulsed one-sided rotation of the driven shaft.
С целью увеличени регулируемого диапазона скорости вращени ведомого вала и упрощени конструкции в предлагаемом вариаторе в качестве передаточного звена использована наружна обойма муфты свободного хода , эксцентрично установленна относительно оси ведомого вала.In order to increase the adjustable speed range of the driven shaft and simplify the design in the proposed variator, the outer sleeve of the free-wheel clutch eccentrically mounted relative to the axis of the driven shaft is used as a transmission link.
На чертеже схематично изображен предлагаемый вариатор.The drawing schematically shows the proposed variator.
Вариатор содержит два параллельных вала: ведущий 1 и ведомый 2. На ведущем валу закреплены один или несколько эксцентриков 3 с регулируемой на ходу величиной эксцентриситета е. Па эксцентрик 3 напрессованThe variator contains two parallel shafts: drive 1 and driven 2. There are one or more eccentrics 3 fixed to the drive shaft with an eccentricity adjusted on the move e. Pa eccentric 3 is pressed on
щарикоподшипник 4. На ведомом валу установлена муфта 5 свободного хода, наружна обойма которой контактирует с щариконодщипником 4, а внутренн обойма жестко соединена с ведомым валом. Наружна обойма выполнена цилиндрической, ось этого цилиндра смещена относительно оси ведомого вала на величину эксцентриситета е. Если в вариаторе применепо несколько эксцентриков и соответственно муфт свободного хода, то их эксцентриситеты равносмещены по фазе друг относительно друга.ball bearing 4. A free-running clutch 5 is installed on the driven shaft, the outer race of which is in contact with the ball bearing holder 4, and the inner race is rigidly connected to the driven shaft. The outer cage is cylindrical, the axis of this cylinder is displaced relative to the axis of the driven shaft by an eccentricity value e. If several eccentrics and, accordingly, one-way clutches are used in the variator, their eccentricities are out-of-phase relative to each other.
Силовое замыкание между ведущим 4 и ведомым 5 звень ми осуществл етс при помощи пружины 6, закрепленной одним концом в корпусе 7, а другим - в обойме 5 муфты.Power closure between the lead 4 and the slave 5 links is carried out by means of a spring 6 fixed at one end in the housing 7, and the other in the holder 5 of the coupling.
Вариатор работает следующим образом. Ведущий вал приводитс в посто нное вращение в любую сторону. Эксцентрик 3 с напрессованным на нем щарикоподшипником 4 приводит в качательное движение обойму муфты 5 свободного хода, преобразующей колебательное движение обоймы в импульсное одностороннее вращательное движение ведомого вала. Пружина 6 обеспечивает посто нный контакт рабочих поверхностей обоймы и щарикоподшипника 4.The variator works as follows. The drive shaft is driven in constant rotation in either direction. The eccentric 3 with a ball bearing 4 pressed on it causes the body of the free-running clutch 5 to swing, which transforms the oscillatory movement of the holder into a pulsed one-sided rotational movement of the driven shaft. The spring 6 provides a constant contact of the working surfaces of the holder and ball bearing 4.
В предлагаемом импульсном вариаторе при применении одного эксцентрика угол поворотаIn the proposed pulse variator when using one eccentric angle of rotation
ведомого звена в дев ть раз больше, чем у известного вариатора с такими же параметрами.the slave link is nine times larger than that of a known variator with the same parameters.
