The beneficial effect of the utility model is:
1. the moving slip ring of the utility model disc type slip ring current-collecting device, quiet slip ring change the plate-like slip ring form of end face contact into; The through-flow contact area of electric current is bigger tens times than carbon brush formula flow area; It is little and phenomenon that cause burning out electrode takes place to have stopped flow area effectively, and wear to electrodes is little;
2. the compression spring is positioned at the outside; The size of its preset pressure guarantees between moving slip ring, the quiet slip ring contact-making surface enough contact pressures are arranged; When diminishing gradually after the wearing and tearing of the contact pressure between moving slip ring and quiet slip ring; Can adjust the size of spring force through the outside nut of adjustment screw rod, make pressure restore, avoid phenomenons such as arcing spark;
3. end face is provided with the pit-holes that is used to deposit lubricant medium in moving slip ring one or both sides; Can deposit lubricant mediums such as colloidal graphite powder in the pit-holes; Guarantee the fluency that slides between slip ring, improved the electric conductivity of electric current between slip ring, also reduced the wearing and tearing between the slip ring simultaneously;
4. to three-phase alternating-current supply, use three cover slip ring current-collecting devices, do not disturb mutually each other;
5. binding post is perpendicular to quiet slip ring setting and be positioned at the outer rim of quiet slip ring, and the free end that binding post is used for wiring is positioned at the outside of insulating press boards, and wiring is more convenient; Make disc type slip ring current-collecting device receive electricity more safe and reliable, prolonged the useful life of disc type slip ring current-collecting device, maintenance operation is convenient simultaneously, and structure is simpler.
