Description

A kind of change the permanent-magnet speed governor turned to

Technical field

The utility model relates to a kind of permanent-magnet speed governor, is specifically related to a kind of change the permanent-magnet speed governor turned to.

Background technology

Permanent-magnet speed governor is the magnetic couple speed governing by permanent magnet, soft (magnetic) that realizes electric motor and load connects, have no effect electrical network harmonic wave produce, reliability height, and can work under the various severe environment such as high temperature, low temperature, humidity, dirt, inflammable and explosive, voltage instability and thunder and lightning, significantly alleviate mechanical vibration, it is widely used in electric power, iron and steel, metallurgy, petrochemical industry, the industries such as papermaking, municipal administration, naval vessel, irrigation and mining. The patent No. be 201420174225.4,201420554495.8,201420755016.9 three sections of patent documents individually disclose the permanent magnetism rotor of three kinds of regulatable magnetic forces, realize moment of torsion transmission when not changing magnetic gap. And the output direction of permanent-magnet speed governor conventional at present is all identical with input direction, needs when low speed starts the input of relatively high power can obtain the torque of needs, thus cause energy dissipation.

Summary of the invention

For the problems referred to above, the utility model provide a kind of improve torque-transfer capability, reduce a kind of of assembly difficulty change the permanent-magnet speed governor turned to.

For solving the problem, the technical scheme that the utility model is taked is: a kind of change the permanent-magnet speed governor turned to, comprise the first outer rotor of being connected with input shaft, the 2nd outer rotor that the first outer rotor connects through reversing gear and be distributed with at least one first permanent magnet and the 2nd permanent magnet along respective outer circumference surface circumference respectively through concentric the first permanent magnetism rotor that passes of output shaft and the 2nd permanent magnetism rotor, the first permanent magnetism rotor and the 2nd permanent magnetism rotor and be provided with interlocking device between the two; The first described outer rotor and the 2nd outer rotor are distributed with the first conductor and the 2nd conductor respectively along respective inner peripheral surface circumference; First permanent magnetism rotor and the 2nd permanent magnetism rotor are respectively equipped with for driving it along the first topworks that output shaft length direction moves and the 2nd topworks.

First outer rotor is consistent with steering input shaft, and through reversing gear effect, the 2nd outer rotor turns to contrary with output shaft. First permanent magnetism rotor, the 2nd permanent magnetism rotor can be altered along output shaft length direction under the drive of topworks, when the first permanent magnetism rotor corresponding with the first conductor position and when rotating, utilize the 2nd topworks by the 2nd permanent magnetism rotor band to the first conductor and the 2nd conductor mid-way, now the 2nd permanent magnetism rotor is without the corresponding conductor in position, and does not have an effect between outer rotor; First permanent magnetism rotor drives output shaft to rotate with the direction identical with input shaft. With reason, when the 2nd permanent magnetism rotor corresponding with the 2nd conductor position and when rotating, the first topworks drives the first permanent magnetism rotor to the first conductor and the 2nd conductor mid-way, and the 2nd permanent magnetism rotor drive output shaft rotates with the direction contrary with input shaft;

For avoid first or the 2nd permanent magnetism rotor be in the first conductor and the 2nd conductor simultaneously under cause output shaft to reverse, the distance between the first described conductor and the 2nd conductor is not less than the first permanent magnetism rotor or the length of the 2nd permanent magnetism rotor.

Described the first topworks, the 2nd topworks can be electric operator, pneumatic actuator or topworks of surging.

For avoiding the first permanent magnetism rotor and the 2nd permanent magnetism rotor to rotate simultaneously, output shaft twists, and described interlocking device can be the interlocking control circuit being made up of coil and rly. of control motor positive and inverse.

In use procedure, permanent-magnet speed governor is installed in certain Controlling System, pressure, flow, liquid level or other control signals are controlled system acceptance and process, then topworks it is provided to, drive first or the 2nd permanent magnetism rotor is selected to move along output shaft length direction by the topworks of topworks, entering the region between the first conductor and the 2nd conductor, adjustment output shaft turns to.

For ease of settling this speed regulator, described reversing gear is connected with support.

The utility model by installing reversing gear on outer rotor so that output shaft can conveniently adjust and turn to, and avoids the problem of the torque needing input relatively high power can obtain needs when low speed starts, it is to increase torque-transfer capability, reduction assembly difficulty.
