Description

The invention relates to the designs of current collection devices for. TRANSFER electrical signals between stationary and rotating objects.

A collector device for transmitting electrical signals between fixed and rotating objects is known, comprising a housing in which a rotor part with a system of contact insulating rings is installed, and fixed contact elements FROM.

The disadvantages of the known device are the complexity of the design due to the presence of a large number of precisely manufactured rotating elements, the need for precise centering of the stator part relative to the rotor, the use of special conductive antifriction materials due to the lack of lubrication of the rubbing surfaces, limited use

due to the complexity and high cost of manufacturing the device and its operation, as well as the lack of adjustment of the force pressing the fixed contact elements to rotating, which leads to the instability of transient resistances.

The purpose of the invention is to ensure the stability of transient resistances, simplify the design of the device and its operation, reduce the cost and expand the area of use.

This goal is achieved by the fact that each fixed contact element is made in the form of a flexible conductive tape, interacting with a continuously lubricated contact ring at least on

1/3 _th the circumference of one end of the tape

rigidly attached to insulated

body parts and the other using

additional adjustable spring

connected to the built-in housing up to ³ 915145

full insulating plate,

movably mounted and serving to disable fixed contact elements from

contact rings. five

Moreover, the conductive tape is made of elastic elastic material, for example, it is 0.1 mm thick beryllium bronze.

In addition, adjustable springs 10 fixed contact elements attached to the insulating movable plate with the help of levers with adjusting screws ,,

In this case, the device is equipped with a fillet, one end of which is immersed in a lubricating fluid,

FIG. 1 shows a structural diagram of one of the possible options for a collector device; in fig. 2 - the same with the cover removed, top view.

The device includes a housing 1 with a hole 2, into which the rotor part 3 freely enters with a system of contact 4 and insulating 5 'rings. Kon-25-stroke rings 4 are continuously lubricated with a lubricating fluid using a wick 6 made of a soft, well-absorbent material, such as felt.

One end of the wick is immersed in the lubricant which has been filled into the casing 1, and a second end pressed against each contact ring 4 by the spring 7 petal shaped plates 8, ₃₅ fiksiruyu- conductive wick 6 in the housing 1,

With the slip ring contact 4 is not less than 1/3 of the circumference of the fixed contact elements are made in the form of flexible current-conducting strips 9 ₄₀ · One end of each tape 9 fastened to an isolated hour, minute 10 of the housing 1 and is soldered to the one 'of the plug contacts connector 11. The other end of the belt 9 is connected by ₄₅ adjustable spring 12 with an insulating movable plate 13 embedded in the body 1, which is rotated around the axis 14 by means of an eccentric 15 and a handle 16, $ ₀

what provides on and off contact elements. The adjustment of the springs 12 is carried out by the levers 17 and screws 18,

The device works as follows.

To activate the current collection with the help of the handle 16, the eccentric 15 and the plate 13 are rotated, resulting in tension of the springs 12, and the conductive tapes 9 come into contact with the slip rings 4 at least 1/3 of the circumference with a small force adjusted beforehand Using screws 18, This contact force is not less than 1/3 of the circumference and the continuous lubrication of the slip rings 4 through the wick 6 ensures the stability of transient resistances and very low wear.

In the absence of the need for a current collection device can be turned off by the handle 16 and the eccentric 15, which completely eliminates its wear.

The proposed collector device does not require precise centering of the stator part relative to the rotor, since the inaccuracies of the centering are compensated by the flexibility of the fixed tape contact elements.

This feature eliminates the landing of the current collector housing on the shaft of the rotor part using ball bearings, which, however, is necessary for the known current collector and for mercury current collectors.

The use of the proposed collector device provides ease of manufacture and adjustment, reliability and low cost by simplifying the design, the stability of transient resistances, increase service life.
