The invention relates to mechanical engineering, in particular, to test equipment, for example, piloting navigation stands and simulators.

A known mechanism for converting rotary motion into an oscillatory one, comprising a base, a drive shaft, a driven member, is designed as a ring spanning a shaft: mounted for oscillation in two mutually perpendicular planes and a device for varying the oscillation amplitude, including two forks having a kinematic connection With drive shaft and ring Ш.

The device for changing the amplitude of oscillations in it is made in the form of a crank rigidly connected to the shaft and connected to the latter by a connecting rod that interacts with one of the frames connected to the other frame is hinged, and the latter is located in the plane of the perpendicular axis of the drive shaft and is rotatably mounted relative to an axis located in said plane.

A disadvantage of the known mechanism is that it does not provide large amplitudes of oscillations of the link link and the test object associated with it, and also has significantly limited operational possibilities for changing the amplitudes and phases of the vibrations.

The purpose of the invention is the expansion of operational capabilities.

This goal is achieved by the fact that in the mechanism for converting rotational motion into an oscillatory one, containing a base, a driving shaft, a driven link, made in the form of a ring spanning the drive shaft, mounted with oscillation in two mutually perpendicular planes, and a device for varying amplitude oscillations, including two forks, having a kinematic connection with the drive shaft and a ring; a device for changing — the amplitudes of the oscillations are performed in the form of two wheels with ring grooves, two washers, mounted x rotatably in the groove and the additional ring pivotally mounted in the base, one of the yokes and positioned between the additional primary ring and the other - between the main

With a ring and a drive shaft, an additional ring placed between the last and main rings, a yoke, a main ring and a yoke placed between the main ring and a driving shaft of the yoke are successively interconnected by means of mutually perpendicular hinge axes, the forks are placed in mutually perpendicular planes, installed rotatably in these planes and rigidly connected to washers.

FIG. Figure 1 shows the mechanism for converting rotational motion into oscillatory, top view; . in fig. 2 is a slit of L-A on (} ig.1; in Fig. 3 is a slit of BB in Fig. 1.

The rotary-to-oscillating-to-oscillating mechanism comprises a drive shaft 1 mounted in bearings 2 and 3, a driven member made in the form of a ring 4 mounted to oscillate in two mutually perpendicular planes and a device for changing the oscillation amplitude comprising a ring 4 made in the form of clips 5 and 6 with annular grooves and 8 washers 9 and 10, installed in grooves 7 and 8, an additional ring 11 with two hinges in semi-axes and 13 mounted in sleeves 14 and J5, placed in the base, having the forms the ring 16 and two forks 17 and 18, having the form of toothed sectors rigidly connected with washers 9 and 10 and interacting with drive elements made in the form of screws 19 and 20, mounted on the drive shaft 1.

An additional ring II, a holder main ring 4 and a holder 6 are successively interconnected by means of mutually perpendicular articulated axes, each of which contains two semi-axes: 21 and 22, mounted in sleeves 23 and 24, semi-axes 25 and 26, mounted in sleeves 27 and 28, and half shafts 29 and 30, mounted in sleeves 31 and 32.

 9 and 10 are fixed against falling out of the grooves 7 and 8 by means of latches 33 and 34, and on the shaft 1 section, spaced between the forks 17 and 18, a gear coupling 35 with end teeth, spring-loaded through a spring 36, is installed. oscillating is carried out in the following way. Through screws 19 and 20, forks 7 and 18 are rotated at the required angle, while together with the forks are rotated relative to the respective hinge axes of the casing 5 and 6, and with them the ring A rotates relative But mutually perpendicular articulated axles 25 and 26, and also axes 29 and 30. When the drive shaft 1 rotates, the forks 17 and 18 rotate together with the crowbar and rotate the washers 9 and 10, which transmit movement, respectively, to the clips 5 and 6, and the latter rotate the ring 4 relative to its articulated axes 25, 26 and 29, 30,

(Put, 1 14 chip oscillations of the ring relative to the mentioned articulated half-axes. The hinge connection of the additional ring P with the base 16 provides freedom of oscillations of the main ring 4 in two mutually perpendicular planes passing through the axis of the drive shaft. If necessary, change the phase of oscillation of the ring 4 changes the mutual position of the forks 17 and 18 by means of the gear coupling 35. The proposed mechanism for converting rotational motion into oscillatory greatly expands the operational capabilities of the device, in particular, the magnitudes of the amplitudes and phase changes of the oscillations of the driven unit and the test object associated with it.
