Муфта содержит наружную торообразную оболочку 1 и внутреннюю 2. Наружна оболочка I закреплена на полумуфтах 3 кольцами 4. Полумуфта 3 смонтирована вместе с упругим кольцом 5 и щпонкой 6 на валу 7.The coupling comprises an outer toroidal shell 1 and an inner 2. The outer shell I is fixed on the coupling halves with 3 rings 4. The coupling half 3 is mounted together with the elastic ring 5 and the tongue 6 on the shaft 7.
Внутренн оболочка 2 закреплена кольцами 8 на полумуфтах 9, которые зафиксированы на валах шайбами 10.The inner shell 2 is fixed by rings 8 on the coupling halves 9, which are fixed on the shafts by washers 10.
При запуске машины в первую очередь начинает нагружатьс внутренн резинова оболочка 2, имеюща м гкую нагрузочную характеристику .When starting the machine, the inner rubber sheath 2, which has a soft load characteristic, starts to be loaded first.
При достижении определенной величины крут щего иомента, возникающего при запуске привода и во врем работы, вал 7 поворачиваетс и включает в работу наружную оболочку 1, обладающую жесткой нагрузочной характеристи36When a certain amount of torque is reached, which occurs when the drive is started and during operation, the shaft 7 rotates and activates the outer shell 1, which has a rigid load characteristic.
кой. За счет м гкого скрушвапн резиновой оболочки обеспечиваетс плавное включение наружной оболочки (резинокорщюй).whoa. Due to the soft crush of the rubber casing, the outer casing (rubber-grommet) is smoothly turned on.
Наличие двух параллельно включенных в работу оболочек обеспечивает передачу больших крут щих моментов, что повышает работоспособность муфты при высокой компактности. Последовательное плавное включение в работу (Оболочек предохран ет машину и муфту от перегрузки во врем пуска, повыша срок службы машины и муфты. Предварительное закручивание резиновой оболочки 2 на угол р, обеспечивает муфте нелинейную характеристику, позвол ющую ей в процессе эксплуатации выходить из зон резонансных частот, что способствует снижениш теплообразовани в оболочках, повышению их срока службы и улуоиению эксплуатационных показателей работы системы валопровода машины.The presence of two shells connected in parallel to the operation ensures the transmission of large torques, which increases the efficiency of the coupling with high compactness. Sequential smooth start-up (The shells protects the machine and the coupling from overload during start-up, increasing the service life of the machine and the coupling. Preliminary twisting of the rubber casing 2 at an angle p provides the coupling with a non-linear characteristic that allows it to go out of the resonant frequency zones , which contributes to the reduction of heat generation in the shells, increase their service life and improve the operational performance of the shafting system of the machine.
Предлагаема конструкци муфты компенсирует перекосы соедин емых валов, хорошо демпфирует свободные крутильные колебани , значительно см гчает динамнгеские воздействи со стороны рабочего органа.The proposed design of the coupling compensates for the distortions of the connected shafts, well damps the free torsional vibrations, significantly alleviates the dynamo effects from the working device.
В исходном положении вал 7 занимает среднее положение паза полумуфты 3, обеспечива равный поворот сопр гаемых деталей в каждую сторону на угол vo , который задаетс с такимIn the initial position, the shaft 7 occupies the middle position of the groove of the half-coupling 3, ensuring equal rotation of the mating parts in each direction by the angle vo, which is specified with this
)4)four
расчетом, чтобы в процессе запуска машины наиболее эффективно снижать амплитуду резонансных колебаний системы валопровода.the expectation is that in the process of starting the machine it is most effective to reduce the amplitude of the resonant oscillations of the shafting system.
