Abstract
The current invention is regarding an electrical slip ring system for high speed applications, which require slip rings to operate at speeds more than 60,000 RPM. It consists of multiple single stage slip rings and multiple gear devices, where all the stators, except the last one, are rotational. The speed limit on the slip ring market, by using the advanced fiber brush bundles, is about 10,000 RPM without cooling, or lubricating. The basic idea is that by designing gears, we can always can make sure the relative speed between the rotor and the stator in each stage is <=10000 rpm.
Claims7
A slip ring system for high speed applications, comprising:
- first and second single stage slip rings;
- a first gear assembly connected to the first and second single stage slip rings,
- each of the first and second single stage slip rings further comprising:
- a ring assembly;
- a brush assembly;
- a ring holder for mounting ring assembly;
- a brush holder for mounting brush assembly;
- wherein the ring holder is rotatable relative to the brush holder;
- wherein the first and second single stage slip rings is connected in series sequence so that the brush holder in a first stage is mechanically connected to the ring holder of a second stage with the first gear assembly, and an output cable assembly of the first stage is connected with an input cable assembly of the second stage.
