Abstract

Изобретение относитс  к машиностроению и может быть использовано в системах автоматического регулировани  дл  обеспечени  двухскоростных режимов, например дл  автоподстройки частоты генератора. Цель изобретени  - снижение установочной мощности двигателей, повышение надежности и упрощение конструкции. Электропривод содержит двигатели 1 и 2, редукторы 3 и 4, соедин емые посредством муфты сцеплени . Муфта состоит из зубчатого колеса 10с выступами 11 и зубчатого сектора 12. В режиме передачи малой угловой скорости крут щий момент с вала двигател  1 передаетс  на редуктор 3, через муфту сцеплени  на выходной вал редуктора 4. В режиме передачи большой угловой скорости включаютс  оба двигател  1 и 2. Крут щий момент через муфту сцеплени  передаетс  на выходной вал редуктора 4. В данном случае редуктор 3 в передаче вращени  не участвует . Такое выполнение электропривода обеспечивает возможность уменьшени  установочной мощности двигателей, быстродействие и надежное срабатывание при необходимости изменени  скорости. 6 ил.The invention relates to mechanical engineering and can be used in automatic control systems to provide two-speed modes, for example, to auto-tune the generator frequency. The purpose of the invention is to reduce the engine installation power, increase reliability and simplify the design. The electric drive contains engines 1 and 2, gear units 3 and 4, connected by a clutch. The clutch consists of a gear wheel 10 with lugs 11 and a gear sector 12. In the low angular velocity transmission mode, the torque from the shaft of the engine 1 is transmitted to the gearbox 3 through the clutch to the output shaft of the gearbox 4. In the high angle velocity mode, both engines 1 and 2. The torque is transmitted through the clutch to the output shaft of the gearbox 4. In this case, the gearbox 3 does not participate in the transmission of rotation. This embodiment of the electric drive provides the possibility of reducing the installed power of the engines, speed and reliable operation, if necessary, change the speed. 6 Il.
