Description

Насто щее изобретение относитс  к электроприводам подающей части врубовых мащин и угольных комбайнов.The present invention relates to electric drives of the feed part of cutting machines and coal combines.

Предлагаемый электропривод отличаетс  от известных тем, что он выполнен по системе генератор-двигатель, образованной из двигател  посто нного тока последовательного возбуждени  и генератора посто нного тока смешанного возбуждени .The proposed electric drive differs from the known ones in that it is made according to a generator-motor system formed from a direct current motor of sequential excitation and a direct current generator of mixed excitation.

Такое выполнен-ие электропривода позвол ет существенно улучшить эксплуатационные характеристики подающей части и упростить ее конструкцию.Such an electric drive can significantly improve the performance of the feed part and simplify its design.

На чертеже изображена схема предлагаемого электропривода.The drawing shows a diagram of the proposed electric drive.

Электропривод представл ет собой систему генератор-двигатель с щироким пределом регулировани  скорости и жесткими механическими характеристиками.The drive is a generator-motor system with a wide speed control limit and rigid mechanical characteristics.

От главного двигател  / врубовой мащины или комбайна вращение передаетс  генератору 2, имеющему две обмотки возбуждени : последовательную 3 и параллельную 4.From the main engine / cutting edge or combine, rotation is transmitted to generator 2 having two field windings: a series 3 and a parallel 4.

Генератор 2 питает двигатель 5, имеющий последовательную обмотку возбуждени  6. От двигател  вращение через редуктор 7 передаетс  к канатному барабану 8.Generator 2 feeds motor 5, having a series excitation winding 6. From the motor, rotation through gearbox 7 is transmitted to cable drum 8.

Регулирование скорости двигател  производитс  изменением результирующей намагничивающей силы генератора при помощи реостата 9 в цепи параллельной обмотки генератора. Намагничивающа  сила параллельной обмотки может быть направлена как согласованно, так и встречно е- намагничивающей силой последовательной обмотки генератора .The motor speed is controlled by varying the resulting magnetizing force of the generator using a rheostat 9 in the parallel winding circuit of the generator. The magnetizing force of the parallel winding can be directed both in a coordinated manner and with the counter magnetizing force of the series winding of the generator.

Изменение напр жени  вращени  двигател  осуществл етс  переключателем 10, который имеет три положени : «включено вперед, «выключено и «включено назад.The change in the voltage of rotation of the engine is made by a switch 10, which has three positions: "on, forwards," off and "on".

Vпpaвлe гPre pетcfaтoмJ5 и переключателем W осуществл етс  руко тками упрацл р } /в 12.In turn, the power adapter J5 and the switch W are operated with knobs p} / in 12.

СК|РОСТЬ вращени  Двигател  5 в приведенной схеме не зависит от Нй «10валу;-чем обеспечиваетс  жестка  характеристика привода ЖecткpfJ,;.(тepиeтик в некоторой степени зависит от магнитного насыщени  г.енера.тор. двигател . Но это вли ние в зоне рабочих скоростей и моментов незначительно и практически не будет сказыватьс  при соответствующем подборе машин.SC | GROWTH of rotation of the Engine 5 in the above scheme does not depend on Ny-10 shaft; -the extent to which the hard drive characteristic is provided is hard; (the technique to some extent depends on the magnetic saturation of the engine-generator. But this effect in the area of workers speeds and moments slightly and practically will not be affected with the appropriate selection of machines.

Предмет изобретени Subject invention

Электралрйв)ф подающей части врубовых мащин и угольных комбайнов , отличающийс  тем, что, с целью улучщени  эксплуатационных характеристик и упрощени  конструкции подающей части, указанный электропривод выполнен по системе генератор-двигатель, образованной нз двигател  посто нного тока последовательного возбуждени  и генератора посто нного тока смешанного возбуждени .The electric drive of the feed part of the cutting machines and coal combines, characterized in that, in order to improve the performance characteristics and simplify the design of the feed part, this electric drive is made according to a generator-motor system formed from a direct current motor of sequential excitation and a mixed current generator excitement.
