Abstract

A current collection device is proposed that contains parallel movable and fixed guides with a contact pair system installed on them, made in the form of conductive rings with spring petals isolated from each other and conductive rings located between them, and bearings, in the clips of which the guides are fixed. It differs in that it additionally contains fixed guides, bearings, contact pairs. One ring of each inserted contact pair is mounted on additional fixed guides, and another ring with spring tabs, each contact pair is mounted on movable guides. The introduction of additional fixed guides, contact pairs with the installation of one ring of each contact pair on additional fixed guides, and another ring with spring tabs of each contact pair on the movable guides provides an increase in the specific capacity of the device by placing additional contact pairs in the previous dimensions.

Description

The proposed current-collecting device relates to electrical engineering and can be used to transmit electrical signals and currents to equipment located in the rotating part of the object.

It is known a current collector device containing parallel movable and fixed guides with a system of contact pairs placed on them, made in the form of stationary rings isolated from each other with spring petals and movable rings located between them.

The disadvantage of this collector is low reliability [1].

Of the known current-collecting devices, the closest in technical essence, structural performance, operational characteristics is a current-collecting device containing parallel movable and fixed guides with a system of contact pairs placed on them, made in the form of outer rings isolated from each other with spring tabs and located between them inner rings, and bearings selected for the prototype [2].

The disadvantage of this current collection device is the low specific capacity, i.e. the number of electrical circuits related to the volume of the device.

The essence of the proposed collector device is that it contains parallel movable and fixed guides with a contact pair system arranged on them, made in the form of conductive rings isolated from each other with spring tabs, and conductive rings located between them, and bearings, in cages which guides are fixed.

It differs in that it further comprises fixed guides, bearings. In addition, it further comprises

contact pairs. One ring of each contact pair is mounted on additional rails, another ring with spring tabs of each contact pair is mounted on movable rails. In this case, additional guides are fixed on the fixed part of the device

The introduction of additional fixed guides, bearings, contact pairs with the installation of one ring of each contact pair on additional guides, and another ring with spring lobes of each contact pair on movable guides provides an increase in the number of electrical circuits in the volume of the device, i.e. increase in specific capacity.

The essence of the proposed collector device is illustrated by the drawings of figures 1, 2, 3.

Figure 1 shows a current-collecting device in a section, figure 2 shows the contact rings (section aa of figure 1); figure 3 section BB of figure 2.

The proposed current collection device comprises: a housing 1, an upper bearing 2 with a cage 3, a lower bearing 4 with a cage 5, additional bearings 6 and 7 with cages 8 and 9, concentrically arranged relative to bearings 2 and 4, common for bearings 2 and 6, cage 10, a common cage 11 for bearings 4 and 7, fixed guides 12 and 14; guides 12 and 14 are installed in the cages of bearings 2-4 and 6-7, respectively, movable guides 13, conductive rings 15, 16, conductive rings with spring tabs 17, 18; insulating parts 19, 20, 21, 22, 23; a leash 24 mounted on movable rails, nuts 25, tightening parts mounted on rails 13.

The device operates as follows. When the current collecting device is operating, the movable guides 13 rotate on which the conductive rings 17 and 18 with spring tabs are mounted. Rings 17 and 18 slide along stationary conductive rings 15 and 16, respectively.

The position of the rings 15 and 16 along the axes of the fixed guides 12 and 14 is determined by the stabilizing pressure of the spring lobes. As a result of the sliding of the springy petals of the conductive rings 17 and 18 along the stationary conductive rings 15 and 16, the current is transmitted in contact pairs.

The radial position of all conductive rings 15, 16, 17, 18 remains constant due to the parallel installation of all the guides 12, 13, 14.

The increase in the specific capacity of the device is achieved by placing additional contact pairs in the previous dimensions.

The proposed current collection device has been tested experimentally. Received positive results. The device is accepted for use.
