Abstract
The utility model discloses a multi-channel conductive central revolving joint. The bottom center of the central revolving joint is provided with a conductive slip ring; a rotor and a stator of the conductive slip ring are fixedly arranged on a rotating shaft and the bottom of a shell respectively; a lead at one end of the conductive slip ring extends out by passing through the central hole of the rotating shaft; and a lead at the other end of the conductive slip ring extends out of the bottom of the shell. The multi-channel conductive central revolving joint has a compact structure, and runs stably; and the phenomenon of electric leakage caused by circuit friction in a rotating process can be avoided, the service life of a circuit part is prolonged, and safe work of a machine is ensured.
Description
Technical field
The utility model relates to a kind of hydraulic element, especially is a kind of central swivel coupling that is applicable to equipment such as engineering machinery, excavator, crane, hoist.
Background technique
The present engineering machinery that has rotating part, like excavator, crane, hoist etc., rotating part adopts central swivel coupling to realize that the oil circuit in the rotary course is communicated with usually; Because present central swivel coupling does not have the circuit communication function; Also need establish independent circuitry in addition, the lead in the circuitry is comparatively in disorder, and lead and lead and lead and mechanical part rub in the machine work; Cause line electrical leakage easily, the generation that causes the accident.
The model utility content
For overcoming above-mentioned technical problem, the utility model provides a kind of reasonable in design, and oil circuit and circuit are integrated, and the multi-path that prolongs circuit part working life conducts electricity central swivel coupling.
For realizing above-mentioned technical purpose; The utility model is to adopt following technological scheme to realize: a kind of multi-path conducts electricity central swivel coupling; Comprise that one is made up of housing, running shaft; Have the central swivel coupling of a plurality of asphalt channels, it is characterized in that: the bottom centre of central swivel coupling is provided with conducting slip ring, and the rotor of conducting slip ring, stator are individually fixed in running shaft and housing bottom; The center hole that the lead of conducting slip ring one end passes running shaft stretches out, and the lead of the other end is stretched out by housing bottom.
The utlity model has following beneficial effect: it is integrated oil circuit part and circuit part through central swivel coupling and conducting slip ring; The solid of rotation that guarantees machinery is worked under rotation status; Its compact structure, stable, can avoid circuit phase mutual friction generation leaky in the rotary course; And then prolonged working life of circuit part, guarantee machine security work.
