Abstract

FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering and transport building industry for developing mechanisms where the change of motor output shaft revolutions is needed. The essence of the invention is that planetary differential is used as transmission ratio transducer. The central wheel of transducer is coupled with an output shaft, whereas the second central wheel is connected to the motor rotor. The rotor is inductive coupled with stator. In addition the cage where pinion pairs are installed and rolled along the central wheels, is connected to the additional rotor which is inductive coupled with stator. But the rotor operates as a generator, when it rotates, generating power energy and returning it to the mains. At the same time the breaking force re-distributes torque moment in the differential shoulders and allows for changing output shaft revolutions when induction coupling with stator is changed. The above mentioned outcome is a result of the claimed invention.
EFFECT: increase of motor efficiency factor.

Description

Изобретение относится к области транспортного машиностроения и других механизмов, в которых необходимо изменение оборотов выходного вала электродвигателя.The invention relates to the field of transport engineering and other mechanisms in which it is necessary to change the speed of the output shaft of the electric motor.

Известны различные пути изменения оборотов ведущего вала электродвигателя переменного тока. Основным способом плавного изменения оборотов является управление частотой питающего переменного тока с использованием преобразователей частоты. Этот способ описан в литературе. Например: Вольдек А.И. Электрические машины. Ленинград. Энергия, 1978, стр.571-572.There are various ways of changing the revolutions of the drive shaft of the AC motor. The main way to smoothly change speed is to control the frequency of the AC supply using frequency converters. This method is described in the literature. For example: Voldek A.I. Electric cars. Leningrad. Energy, 1978, pp. 571-572.

Недостатком этого способа является большая стоимость преобразователей, их сложность, низкий КПД, ненадежность и то, что для преобразователей электродвигателей большой мощности пока не создана надежная элементная база.The disadvantage of this method is the high cost of the converters, their complexity, low efficiency, unreliability and the fact that for converters of electric motors of high power has not yet created a reliable elemental base.

Задачей изобретения является осуществление плавного изменения оборотов выходного вала устройства с изменением передаточного отношения во всем диапазоне скоростей, в зависимости от нагрузки, при оптимальном режиме работы электродвигателя на постоянных оптимальных оборотах и, как результат, достижение оптимальности разгонных характеристик, повышение коэффициента полезного действия, удешевление производства и упрощение управления.The objective of the invention is the implementation of a smooth change in the revolutions of the output shaft of the device with a change in the gear ratio over the entire speed range, depending on the load, with the optimal operation of the electric motor at constant optimal revolutions and, as a result, achieving optimal acceleration characteristics, increasing efficiency, and cheapening production and simplified management.

Указанная цель достигается тем, что согласно изобретению в качестве преобразователя передаточного отношения используют планетарный дифференциал, одно из центральных колес которого связано с выходным валом, а второе центральное колесо с ротором электродвигателя, который индуктивно связан со статором. Водило, на котором установлены пары сателлитов, обкатывающиеся по центральным колесам, связано с дополнительным ротором, который также связан индуктивно со статором, но при вращении работает в генераторном режиме, вырабатывая электроэнергию, возвращая ее в сеть, а тормозящая его при этом сила перераспределяет крутящий момент в плечах дифференциала. Это позволяет при постоянных оптимальных оборотах ротора электродвигателя изменять в зависимости от нагрузки обороты выходного вала.This goal is achieved by the fact that according to the invention, a planetary differential is used as a gear ratio converter, one of the central wheels of which is connected to the output shaft, and the second central wheel with an electric motor rotor, which is inductively coupled to the stator. The carrier, on which pairs of satellites are installed, which run around the central wheels, is connected with an additional rotor, which is also inductively connected to the stator, but when rotated it works in the generator mode, generating electricity, returning it to the network, and the force that slows it down distributes torque in the shoulders of the differential. This allows for constant optimal rotor speeds of the electric motor rotor to change the output shaft speed depending on the load.

Изобретение поясняется чертежом. На чертеже показан электродвигатель с вертикальной осью вращения. Со статором 1 индуктивно связан ротор 2, который свободно вращается на оси, но жестко связан с центральным зубчатым колесом 3 планетарного дифференциала, по которому обкатывается сателлит 4, жестко связанный с сателлитом 5, который обкатывается по центральному колесу 7, жестко связанному с выходным валом 8. Оси сателлитов свободно вращаются на водиле 6, являющемся корпусом дополнительного ротора 9, который также индуктивно связан со статором, но работает в режиме генератора, возвращая при вращении выработанную им электроэнергию в цепь (подключение обмоток не показано). Возникающее при этом тормозящее усилие перераспределяет крутящий момент в плечах дифференциала, создавая условия для раскрутки выходного вала 8. Дифференциал может быть построен так, чтобы в плечо дополнительного ротора поступала значительно меньшая доля энергии, необходимая для уравновешивания второго его плеча, а вся электроэнергия, выработанная дополнительным ротором, расходовалась на увеличение напряженности электромагнитного поля статора. Коммутирующее устройство, определяющее величину тормозящего усилия (на схеме не показано), при необходимости может находиться в цепи обмотки дополнительного ротора либо реализовано любым из известных способов, например изменением зазора между статором 1 и дополнительным ротором 9.The invention is illustrated in the drawing. The drawing shows a motor with a vertical axis of rotation. A rotor 2 is inductively connected to the stator 1, which rotates freely on the axis, but is rigidly connected to the central gear 3 of the planetary differential, on which the satellite 4 is rolled around, rigidly connected to the satellite 5, which is rolled around the central wheel 7, rigidly connected to the output shaft 8 The axis of the satellites rotate freely on the carrier 6, which is the body of the additional rotor 9, which is also inductively connected to the stator, but operates in the generator mode, returning the electricity generated by it to the circuit during rotation (I connect windings are not shown). The braking force arising in this case redistributes the torque in the differential arms, creating conditions for the promotion of the output shaft 8. The differential can be constructed so that a much smaller fraction of the energy necessary to balance its second arm enters the arm of the additional rotor, and all the electricity generated by the additional rotor, was spent on increasing the electromagnetic field of the stator. A switching device that determines the amount of braking force (not shown in the diagram), if necessary, can be located in the winding circuit of the additional rotor or implemented by any of the known methods, for example, by changing the gap between the stator 1 and the additional rotor 9.
