A magnetic coupling transmission device with constant power and speed regulation

Abstract

The invention provides a magnetic coupling transmission device running at constant power and adjustable speed. A second electromagnetic induction component is arranged on the shell of a frame and an input shaft or an output shaft. A converter device in a control mechanism receives electric energy from a first electromagnetic induction component arranged between the input shaft and the output shaft, modulates the electric energy and inputs the electric energy to the winding of the second electromagnetic induction component so as to enable the second electromagnetic induction component to produce electromagnetic torque assisting the input shaft or the output shaft in rotating. According to the magnetic coupling transmission device running at constant power and adjustable speed, slip power generated due to rotation speed difference between the input shaft and the output shaft can be collected fully and used to drive the input shaft or the output shaft to rotate, so that the input power from a drive device can be all converted into the output power of the output shaft under the condition of ignoring mechanical loss and stray loss, and the size of the output power of the output shaft is equivalent to the size of the input power of the drive device.

technical field [0001] The invention relates to a magnetic coupling transmission device for constant power speed regulation operation, especially for constant power transmission, which can increase the transmitted torque when the output speed is low, and belongs to the field of mechanical transmission. Background technique [0002] From the perspective of transmission technology, the speed regulation operation of large rotating machinery comes from two requirements, one is the requirement of production technology, and the other is the requirement of energy saving. At present, the variable speed operation of large rotating machinery, the most representative practical applications are: frequency conversion speed regulation technology of three-phase asynchronous motor or permanent magnet motor, series pole speed regulation technology of wound rotor motor and speed regulation type hydraulic coupling transmission technology .
