Problems solved by technology

In electric slip rings, there are mainly brush slip rings, rolling slip rings and mercury slip rings. Brush slip rings are multi-point contact sliding friction slip rings; rolling slip rings are multi-line contact rolling friction slip rings; mercury slip rings are surface Contact frictionless sealing slip ring; the brush slip ring mainly adopts the technology that the carbon brush is close to the copper ring, the disadvantage is that the dynamic friction will produce a large amount of carbon alloy powder, which will reduce the service life and require frequent cleaning; the rolling slip ring uses similar to the bearing The solution is to connect the relatively moving conductors together through rolling elements. The friction is rolling friction, which cannot evenly exert the conductivity of each rolling element, and the manufacturing errors of the rolling elements and the inner and outer raceways cause the rolling elements to rotate during rotation. There may be frequent switching between non-contact and contact, which will lead to the appearance of a large number of arc sparks, and the arc will easily ablate the rolling elements and inner and outer slideways, and accelerate damage; mercury slip rings use mercury as a conductive medium, which will not produce friction, but However, it has high requirements for sealing, and the mercury pollutes the environment and is expensive

Abstract

The invention discloses an axial surface contact slip ring of a flexible contact electrode. The slip ring comprises a first supporting shell, a second supporting shell, a supporting shaft, a pluralityof first disc-type flexible electrodes, a plurality of second disc-type flexible electrodes, a plurality of flexible rolling mechanisms and a plurality of isolation plates, the supporting shaft is arranged in the first supporting shell and the second supporting shell; the plurality of second disc-type flexible electrodes are embedded in the supporting shaft; the multiple isolation plates are fixedly arranged on the first supporting shell and the second supporting shell. Each of the inner wall of the first supporting shell and the inner wall of the second supporting shell is provided with a wire groove and a first electrode key groove, each first disc-type flexible electrode is embedded in the corresponding first electrode key groove, and each second disc-type flexible electrode and the corresponding first disc-type flexible electrode are in rolling connection through a flexible rolling mechanism. The defects that an existing slip ring is small in contact area and large in friction loss and needs to be sealed are overcome, the friction loss can be reduced, the contact area is increased, and sealing is not needed.

Description

technical field [0001] The invention relates to the technical field of slip rings, in particular to a slip ring in which the axial surface of a flexible contact electrode contacts. Background technique [0002] Slip ring is an electrical component that communicates with the rotating body and transmits energy and signals. According to the transmission medium, slip rings are divided into electric slip rings, fluid slip rings, and smooth rings, which can also be collectively referred to as "rotary communication" or "rotary communication". Slip rings are usually installed at the center of rotation of the equipment, and are mainly composed of two parts: rotating and stationary. The rotating part is connected to the rotating structure of the device and rotates with it, called the "rotor", and the stationary part is connected to the energy source of the fixed structure of the device, called the "stator". In electric slip rings, there are mainly brush slip rings, rolling slip ring...
