Description

Устройства дл  передачи вращени  в герметично уплотненную полость, включающие два кривошипа, взаимодействующие с установленным на шарнире коромыслом, и уплотн ющий сильфон, жестко соединенный с корпусом устройства и коромыслом, известны.Devices for transmitting rotation into a hermetically sealed cavity, comprising two cranks, cooperating with a swivel beam, and a sealing bellows rigidly connected to the device body and the rocker arm are known.

Недостатком известных устройств  вл етс  то, что в них не обеспечиваетс  разгрузка шарнира коромысла от действи  осевых усилий, обусловленных разностью давлений раздел емых полостей. Чем выше осевое усилие, тем больше размеры опоры коромысла и силы трени  опорах, а значит, и ниже к.п.д.A disadvantage of the known devices is that they do not provide unloading of the hinge of the rocker arms from the action of axial forces caused by the pressure difference between the cavities to be separated. The higher the axial force, the greater the size of the support of the rocker arm and the strength of the training of the supports, and hence the lower the efficiency

Описываемое устройство дл  передачи вращени  в герметично уплотненную полость позвол ет разгрузить шарнир коромысла Ьт действи  осевых усилий.The described device for transmitting rotation into a hermetically sealed cavity allows unloading the hinge of the rocker arm by the action of axial forces.

Это получаетс  благодар  тому, что в устройстве установлен симметрично первому сильфону относительно шарнира второй сильфон, сообщенный с первым, а также соединенный с корпусом и коромыслом.This is due to the fact that the second bellows is connected symmetrically to the first bellows relative to the hinge, which is in communication with the first, and also connected to the body and the rocker.

Вследствие этого силы трени  в опорах коромысла и размеры опор Не завис т от разности давлени  и диаметра сильфонов.As a result, the frictional forces in the rocker supports and the sizes of the supports do not depend on the pressure difference and the diameter of the bellows.

Описываемое устройство имеет меньшие габариты и более высо-. кий К.П.Д., чем известные устройства. Оно легко выполнимо в конструктивном отношении и позвол ет нримен ть стандартные подшипники качени .The described device is smaller and taller. cue KPD, than the known device. It is easily constructively feasible and allows standard rolling bearings to be used.

На фиг. 1 изображено устройство дл  передачи вращени  в герметично уплотненную полость в продольно осевом разрезе; на фиг. 2 - то же, разрез по Л-Л.FIG. 1 shows a device for transmitting rotation into a hermetically sealed cavity in a longitudinal axial section; in fig. 2 - the same, a section on LL.

Ведущий вал-У посредством кривошипа 2 приводит в качательное движение коромысло 5, соединенное кривошипом 4 с ведомым валом 5. К коромыслу 3 с двух сторон прикреплены два, соединенных с корпусом 6, сильфона 7, полости которых сообщаютс  между собой.The drive shaft-U by means of the crank 2 rotates the rocker arm 5, which is connected by crank 4 to the driven shaft 5. Two arms connected to the housing 6, bellows 7, the cavities of which communicate with each other, are attached to the rocker arm 3 on both sides.

Коромысло 3 установлено на карданном подвесе, состо щем из ра.мки 8, четырех подшипников качени  9 и четырех попарно соединенных с корпусом и коро.мыслом шипов 10The yoke 3 is mounted on a gimbal suspension consisting of a ram 8, four rolling bearings 9 and four pairs of which are connected in pairs with the casing and core of spikes 10
