(54) CURRENT DEVICE

one

The invention relates to current collection devices that carry out electrical communication between fixed and rotating nodes, and can be used in devices.

A collector device is known which contains concentrically arranged stationary and rotating conductive rings, elastic conductive rings installed between them with tension, equipped with shafts, hubs and elastic disks, a separator installed with the possibility of free rotation about the axis. In this case, the shafts are rigidly fixed on the separator and mounted with the possibility of free rotation relative to the hubs 1.

The shortcomings of this construction should be attributed to a short service life, since the elastic conductive rings undergo rolling alternating deformations during their rolling, and the elastic discs are subject to aging over time, as well as the low manufacturability of the design, due to the fact that it contains labor-consuming elastic conductive rings which should have very thin walls.

to the moment of friction device was minimal. In addition, securing the elastic discs inside the elastic ring is also laborious.

It is also known a device comprising two concentrically arranged rigid rings, an elastic conductive ring placed between them, rolling bodies mounted with a tension between an elastic and one of the rigid rings, a corrugated conductive tape placed between an elastic ring and another rigid ring, provided with restricting projections with a gap in the corrugations of the tape 2.

However, this device has a short service life as the elastic conductive

15 a ring that is not secured against rotation can be turned under the action of friction forces between them and bodies, and this leads to sliding friction between them and the corrugated current-conducting tape, which leads to abrasion of the silver (gilded) surfaces of the contacting parts, the low manufacturability of the design is due to that it contains labor-consuming parts, such as a corrugated conductive tape and an elastic conductive ring, which have a very thin wall.

Closest to the proposed technical entity is a collector device containing concentrically arranged moving and rotating conductive rings and installed between them conductive gear rolling bodies 3.

The disadvantages of this design also include a short service life due to the fact that elastic rings undergo constant alternating deformations and low manufacturability of the structure during rolling because elastic toothed conductive rings are very laborious to manufacture because of the need to cut a tooth on a thin-walled flexible crown in a deformed state, with the wave of deformation all the time moving around the crown, which requires special technological equipment.

The purpose of the invention is to increase the service life and increase the manufacturability of the device.

The goal is achieved by the fact that the rolling gear bodies are made in the form of three coaxially arranged disks and springs installed between them, with the possibility of turning each of the extreme disks relative to the middle one, the middle disk and one of the extreme ones interacting with the gear crown of the fixed conductive ring. The middle and other extreme disks are with a gear ring of a rotating conductive ring.

In order to reduce the moment of friction and reduce shum during transmission, the extreme disks are made of plastic.

FIG. 1 shows a current collection device; in fig. 2 shows section A-A in FIG. one.

The current collection device comprises a fixed conductive ring 1 with an inner gear 2; concentrically arranged with respect to it a rotating conductive ring 3 with a ring gear 4, mounted on the axis 5; located between the stationary 1 and the rotating 3 rings, conductive gear rolling bodies made in the form of a package of three gear disks, between which springs 6 are installed, which unfold one of the extreme disks 7 relative to the middle disk 8 and the other extreme disk 9 relative to disk 8. The disks 7 and 9 are made of plastic to reduce friction and noise during operation. The middle disk 8 and the disk 7 interact (engage) with the ring gear 2, and the middle disk 8 and the disk 9 engage with the ring gear 4. This is done so that the disk 8 with the ring teeth 2 and 4 always has continuous power contact.

The device works as follows.

When the internal conductive ring 3 rotates, the conductive rolling gear bodies consisting of three disks 7-9 also begin to rotate. In this case, the medium conductive disk 8, due to the disks 7 and 9, as well as the action of the springs 6, contacts the conductive teeth of the crowns 2 and 4 with its teeth with voltage. The reliability of the contact is guaranteed by the action of the spring 6. Transferring (current) energy from the ring 3 to ring 1 occurs through the conductive disk 8, which contacts the two first through gearing.

The implementation of rolling gear bodies in the form of three coaxially arranged disks with springs deploying each of the extreme disks with respect to the middle one, which alternately paired with one of the extreme disks engages with the toothed rims of the stationary and rotating conductive rings, due to the fact that there are no alternating deformations, and the device works as a simple gear transmission, and also improves the manufacturability of the device, since s in the manufacture and production of long ago mastered.
