SU1203292A1 - Input of rotary motion - Google Patents

Description

one

The invention relates to vacuum. intelligent technology and can be used to carry out technological operations inside the vacuum chamber.

The purpose of the invention is to increase reliability by increasing the long-lasting sealing bellows.

Fig. 1 shows the insertion of a rotational motion, a slit; in fig. 2 - view A in FIG. 1, FIG. 3 - section BB in FIG. 1.

The rotational movement input contains the drive 1 and the driven 2 shafts in the supports of the input body 3. On the front surface of the drive 1 and driven 2 shafts there are spherical recesses 4 in which Balls 5 are located. Between the follower 2 and the drive 1 shafts, an intermediate element in the form of a disk 6 is mounted with an eccentric system, on the end surfaces of which there are two

 The rions are profiled grooves. The profiled groove describes the shape of the ring gear. Intermediate element hermetically

5 is connected by a bellows 8 with the case 3 input.

Entering the rotational motion works as follows.

When the shaft rotates 1 balls 5

10 interact with the teeth of the disk 6, intrinsic to one of one of the end surfaces of the disk 6. Due to the fact that the intermediate element is installed with an eccentricity and

15 is fixed against rotation by the bellows 8, it. makes a circular plane-parallel oscillatory motion. In the process of this movement, the teeth, made on the other end 20 surface of the disk 6, interact with the balls 5 of the driven shaft, together with him, the rotational motion in vacuum. .
