Abstract

The utility model relates to a conducting slip ring, in particular to a conducting slip ring which can be applied to a continuous rotation angle measurement device of a tracking rotating table. The conducting slip ring comprises rotating shafts, the conducting slip ring, resolver stators, resolver rotors and a position seat body, wherein the rotating shafts are respectively and fixedly arranged in inner bores of the position seat body through bearings; the conducting slip ring is fixedly arranged in shaft holes of the rotating shafts; the resolver stators and the position seat body are fixed; the resolver rotors and the rotating shafts are fixed; the resolver rotors are arranged outside the resolver stators; the resolver rotors are in clearance fit with the resolver stators; and cables of the resolver rotors are led out through gaps between the rotating shafts and the conducting slip ring. By utilizing the conducting slip ring, resolver rotor wires and slip ring stators cannot rub with each other, and the service life is long.

Description

A kind of conducting slip ring of continuous rotation angle-measuring equipment

Technical field

The utility model relates to a kind of conducting slip ring, particularly can be applied to the conducting slip ring that tracking table rotates angle-measuring equipment continuously.

Background technology

For realize the photoelectric tracking turntable in n * 360 ° the angular position measurement during rotation continuously; Need follow the tracks of in the seat at turntable and use resolver; The resolver rotor is connected with axle system, and stator and orientation pedestal are connected, and this resolver rotor and stationary part all have outlet.Owing to receive the restriction of turntable integral structure layout, resolver generally is positioned at the bottommost of following the tracks of seat, wherein revolves change rotor and azimuth axle and moves simultaneously; So revolve the rotor portion of the space of the cable that becomes rotor between needing to refer to from azimuth axis and conducting slip ring through slip ring, and the rotor of common slip ring is interior, stator outside; Make the disadvantage of slip ring in this way be: to revolve the cable during that becomes rotor through slip-ring rotor; Because the space between rotating shaft and slip ring stator is very little, revolving change rotor line must be stretching, otherwise cable can rub with the slip ring stator; Time has been grown and can cause cable damaged, thereby has influenced the operate as normal of whole system.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of conducting slip ring of continuous rotation angle-measuring equipment, and it can not cause to revolve and become rotor line and the friction of slip ring stator, long service life.

The technical scheme that its technical problem of the utility model solution is taked is: it comprises rotating shaft, conducting slip ring, revolves set, revolves change rotor and orientation pedestal; Rotating shaft passes through bearing fixing in the endoporus of orientation pedestal; Fixing conducting slip ring in the axis hole of rotating shaft, described set that revolves is fixed with the orientation pedestal, and described revolving becomes rotor and rotating shaft is fixed; Revolve set outside revolving the change rotor, revolve the cable that becomes rotor and draw through the space of rotating shaft and conducting slip ring.

The utlity model has advantage: 1. revolve distortion, the wearing and tearing that can not cause cable behind the space of cable that becomes rotor in the orientation pedestal through rotating shaft and conducting slip ring; 2. the cable of rotor need not be stretching, in the space, is in free state, brings great convenience for away line process.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Accompanying drawing is the utility model cutaway view.

Embodiment

Shown in accompanying drawing, the utility model comprises rotating shaft 4, conducting slip ring 3, revolves change rotor 5, revolves set 6 and orientation pedestal 1, and rotating shaft 4 passes through bearing fixing in the endoporus of orientation pedestal 1; Fixing conducting slip ring 3 in the axis hole of rotating shaft 4; The described set 6 that revolves is fixed with orientation pedestal 1, and the described change rotor 5 that revolves is fixed with rotating shaft 4, revolves set 6 outside revolving change rotor 5; The two matched in clearance is revolved the cable 2 that becomes rotor 5 and is drawn through the rotating shaft 4 and the space of conducting slip ring 3.
