Abstract
The utility model discloses a helical pair type permanent magnet governor. The helical pair type permanent magnet governor comprises a cylindrical permanent magnet rotor, a cylindrical conductor rotor and an adjustment mechanism. One of the rotors is a driven rotor, and the other rotor is a driving rotor, wherein the driven rotor can be moved back and forth on the rotor shaft. The adjustment mechanism is a helical pair mechanism which is composed of a gear pair and a push assembly. A regulation motor which is controlled by an actuator is installed on a governor supporting housing, and when the regulation motor is in forward rotation and reverse rotation, the sliding sleeve of the gear pair is driven by the regulation motor so as to be moved back and forth, so that the driven rotor is driven by the push assembly so as to be moved back and forth to change the relative position of the driven rotor and driving rotor in the axis direction. According to the utility model, the adjustment mechanism is a helical pair mechanism, and the threads of the helical pair mechanism can be machined to be very fine, wherein the smaller the thread pitch is, the higher the adjustment accuracy is, so the helical pair mechanism is the best permanent magnet speed adjustment method.
Description
Technical field
The utility model relates to permanent-magnet speed governor.
Background technology
Permanent-magnet speed governor is comparatively advanced at present speed regulator.Its primary structure is that Yi Bian be the power rotor that is connected with motor, another side is the driven rotor that is connected with load, regulates both air gaps or coupling area by governor motion, realizes torque adjustment.It has simple and reliablely, flexible start, machinery-free connects separating vibration, tolerance the is larger error of centralization, adapt to each critical piece of various adverse circumstances places such as (comprise that voltage ripple of power network is large, harmonic wave is serious) inflammable and explosive, moist, dust, prolongation drive system useful life, maintenance cost low, without harmonic wave, contamination-free, without the EMI(electromagnetic wave) advantages such as interference, long service life.
The most frequently used fit structure of power rotor and driven rotor is inside and outside tubular, inside and outside double-layer structure is N, the S utmost point of corresponding permanent magnet respectively, the tubular construction magnetic force direction is for radially, by regulating tubular p-m rotor and tubular conductor rotor at the relative position of axis direction, to change p-m rotor and conductor rotor coupling area, the moment of torsion that transmits be can change between the two, controllable output torque and rotating speed realized.
The governor motion of permanent-magnet speed governor mostly is pinion and-rack at present, adjusts the motor operation by actuator control, adjusts motor driven gear and rotates, and gear promotes tooth bar and moves around, thereby makes p-m rotor or conductor rotor produce mutual displacement at axis direction.Because the pinion and rack type of belt drive is limit, and makes the speed regulator adjusting speed accuracy not high, and is inapplicable to the demanding occasion of some adjusting speed accuracies, and some special occasions are sought after both having the permanent-magnet speed governor advantage, require the high speed regulator of adjusting speed accuracy.
Summary of the invention
The purpose of this utility model is to propose a kind of high accuracy permanent-magnet speed governor.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of screw pair formula permanent-magnet speed governor, it is a kind of tubular permanent-magnet speed governor, comprises tubular p-m rotor, tubular conductor rotor and regulates the governor motion of both coupling areas; One of them rotor is driven rotor, and another rotor is power rotor, and driven rotor can move around on armature spindle; It is characterized in that, governor motion is a kind of screw pair mechanism; Screw pair mechanism comprises gear pair and pushing component; Gear pair is comprised of a slip cap with the passive gear wheel of external tooth and internal tooth and the outer silk of band, the outer silk engagement of passive gear wheel internal tooth and slip cap, and slip cap is installed on the load rotor axle; Pushing component is comprised of the push rod on the load rotor axle and thrust bearing; Slip cap withstands on the thrust bearing; At the speed regulator support housing adjustment motor of being controlled by actuator is installed, adjusts on the motor output shaft driver pinion that is meshed with passive gear wheel external tooth is installed; Drive slip cap when adjusting motor positive and inverse and move around, move around thereby make pushing component drive driven rotor, change driven rotor and power rotor at the relative position of axis direction.
Using method is: main empty load of motor is started, when turning to rated speed, start and adjust motor, passive gear wheel rotates, and drives slip cap and push rod and moves to motor drive direction, promotes the coupling of driven rotor and power rotor.
When needs at 0 rotating speed between the rated speed during speed governing, control the rotation number of turns of adjusting motor by adjusting actuator, make power rotor and driven rotor meet the requirements of coupling distance.
Because governor motion of the present utility model is a kind of screw pair mechanism, it is very thin that the screw thread of screw pair mechanism can be processed, and more the whole precision of ditty is higher for pitch, so screw pair mechanism is best a kind of permanent magnetic speed-adjusting mode.
