Description

The invention relates to mechanical engineering.

A device for transmitting rotation through a sealed partition, containing two crank shafts and an intermediate disk £ 1]. ⁵

The disadvantage of this device is the complexity of the design.

It is also known a device for transmitting rotation through a sealed partition, containing the leading and the driven ^{, 0} shafts kinematically connected through a mechanism for converting rotational motion into reciprocating, connected by a bellows to a sealed partition [2].

The purpose of the invention is to ensure the continuity of the movement of the driven shaft and increase the service life of the device.

This is achieved by the fact that the proposed device is equipped with additionally distributed additional mechanisms for converting rotational motion into reciprocating motion and a gear transmission connecting them to the driven shaft. A washer fixed at an angle to its axis on the drive shaft is in contact with the mechanisms for converting rotational motion into reciprocating.

The drawing shows the proposed device, a longitudinal section.

The device includes a drive shaft 1, equipped with an oblique washer 2, intermediate mechanisms for converting rotational motion into reciprocating, consisting of a driving element 3 and a driven element 4. The driven element is made in the form of a shaft with an endless helical groove, which includes a cracker of the switching mechanism, movably fixed on the inner surface of the sleeve of the leading element of the intermediate device. When the reciprocating movement of the leading element 3 between the two extreme positions, the driven element 4 of the intermediate device performs an intermittent intermittent movement. The oblique washer 2 rests on the movable rods of the driving elements 3 of the intermediate devices. The output ends of the driven elements of the intermediate devices are equipped with gears 5, which are engaged with the gear ring - Vcom 6 of the driven shaft 7 and are thus in a rigid mechanical connection. ' The driving elements of all the intermediate devices included in the device are mixed with respect to each other. The vacuum chamber is sealed by bellows 8 and a sealed partition 9.

The device operates as follows.

When the drive shaft 1 rotates, the oblique washer 2 mounted on it presses the ends of the rods of the driving elements 3 of the intermediate devices, informing them of the reciprocating motion. In this case, the driven elements 4 of the intermediate devices carry out intermittent non-reversible. rotational motion. Upon reaching the extreme (left and right) inoperative positions when switching the crackers of the driving elements to the opposite grooves, the driving elements are forced to move in the opposite direction due to the interconnected gear transmission ve— _; home elements of other intermediate devices that are in the working position between the two extreme inoperative positions. Thus, all the intermediate nodes that make up the design of the device, each of which performs intermittent rotational movement of the driven input shaft, rigidly connected to each other and the driven rotation input shaft by gear transmission, sequentially bring each other out of idle positions, providing at this continuous 727889. _This uniform, non-reversible rotation of the driven shaft of the device.

In the proposed device, the bellows do not experience bending deformations and ₅ shear deformations, as occurs in all known constructions of devices for transmitting non-reversible continuous rotation of the driven shaft, do not experience fatigue stresses that cause a period
