Description

The invention relates to a fine-tuning instrument, in particular to devices for measuring angular sorrows, and can be used, for example, in tachometers.

Known transmission device rotate. body movement, comprising a housing, a shaft with a driving element arranged therein, a driven shaft with a holder on which bent elastic elements are attached that are in contact with the driving element, a ratchet wheel fixedly mounted and cooperating with elastic elements. The leading element is made in the form of a disk fixedly mounted on the shaft 1.

The disadvantages of the known device are the discontinuity of rotation of the driven shaft with the continuous rotation of the drive and the inability to change the gear ratio of the device.

The aim of the invention is to expand the operational capabilities of the rotational motion transmission device.

The goal is achieved by the device for transmitting rotational motion, comprising a housing, a shaft with a driving element, a driven shaft with a holder, on which are bent elastic elements in contact with the driving element, a ratchet fixed and interacting with elastic elements, the leading element is made in the form of a cam having a radial groove mounted with the possibility of moving it in the radial direction and simultaneously interacting with at least two elastic elements.

In this case, the elastic elements. Can be differently bent. .

FIG. 1 shows a device for transmitting rotational motion; in fig. 2 - fastening of the driving element on the shaft; on. FIG. 3 - an output shaft of a driven shaft with curved elastic elements.

Transmission device rotary; The movement comprises a shaft 1 mounted in a housing (not shown), a driving element 2 placed thereon, made in the form of a cam with a radial groove. The driving element 2. is fixed on the shaft 1 by a nut 3 with a self-locking washer 4. The driving element 2 contacts the driven shaft holder 5 (not shown) through curved elastic elements 6. A fixed ratchet wheel 7 is mounted in the case, which interacts with elastic elements 6 of the holder five:

The rotational motion transmission device operates as follows.

When the rotation of the shaft 1 with

5 on it lead element 2 occurs

alternate deformation (straightening)

/ curved elastic elements 6 and, trace:

tions, alternately increasing their length

protruding from the clip 5 ends which,

rests against fixed ratchet tooth

0 wheels 7, rotation 5 is driven into rotation,

and with it the drive shaft of the device.

In order to ensure the continuity of rotation of the driven shaft, the driving element 2 is mounted so that it constantly contacts 5 with at least two curved elastic elements 6.

The adjustment of the gear ratio of the device is carried out by moving the driving element 2 relative to the shaft 1. To increase the gear ratio 0, the leading element 2 moves upwards, to decrease - downwards (Fig. 1).

In order to ensure the transmission of motion with a given function of changing the gear ratio, the depth of bending (Fig. 3) of the curved elastic elements 6 can be made different.

The device for transmitting rotational motion allows using it in various measuring devices, which greatly simplifies their design and reduces it. the cost of their manufacture and operation.
