(54) ПРИВОД ДВУХЧЕРВЯЧНОГО ЭКСТРУДЕРА ДЛЯ ПЕРЕРАБОТКИ ПЛАСТМАСС(54) DRIVE OF TWO-GRADE EXTRUDER FOR PLASTICS PROCESSING

Изобретение относитс  к машиност роению, а именно к зубчатым переда-, чам двухчерв чных экструдеров. Известен привод двухчерв чного экструдера дл  переработки пластмасс содержащий две пары соосных косозубых ведущих шестерен, имеющих в каждой паре противоположное направление зубьев, зацепл ющиес  с ними ведомые шестерни, одна из которых крайн   выходна , а ведуща  крайн   шестерн  незацепл юща  с ней - входна , и расположенные между торцами шестерен и соедин кмдие их шлицевые муфты, часть из которых HMeieiT размещенные в них упругие элементы Однако дл  известного привода характерно недостаточно равномерное распределение нагрузки. Целью изобретени   вл етс  повышение равномерности распределени  нагрузки и нагрузочной способности при вода . Дл  достижени  этой цели упругие элементы размещены в муфтах, устаиов ленных между торцами napi ведущих и ведоьвлх шестерен, кроме пар. вкгаочгио щих входную и выходную шестерни. Кро ме того, в одной из шестерен, св зан ной с муфтой, имеющей упругий элемент , выполнено осевое резьбовое отверстие , а привод снабжен винтом,размещенным в от;верстии и взаимодействующим с упругим элементом. На чертеже изображен предлагаемый привод, общий вид. Привод содержит две пары соосных косозубых входных шестерен 1, 2 и 3, 4, имеющих попарно противоположное направление зубьев, наход щиес  в зацеплении с выходными шестерн ми 5-8. Шестерни 3 и 4, 5 и 6 установлены независимо в подшипниках подвижно в осевом направлении и св заны между собой и с шестерн ми 2 и 7 шлицевь ™ муфтами 9-11. Входна  шестерн  1 приводитс  во вргицение от редуктора (не показан) , а выходна  шестерн  8 св зана с черв ком 12. Пары шестерен 1, 2 и 7,8 зафиксированы в осевом направлении и выполнены заодно с валами. Шестерни 1, 4, 6 и 7 имеют правое направление зубьев, остальные - левое.Между входными шестерн ми 3 и 4 внутри шлицевой муфты 9 и между выходными шестерн ми 5 и 6 внутри муфты 10 установлены упругие элементы 13, выполненные , в виде тарельчатых пружин. В резьбовое отверстие крайней входнойThe invention relates to machine building, namely to gear gears of twin-screw extruders. The drive of a double-screw extruder for plastics processing is known, which contains two pairs of coaxial helical gears, each having the opposite direction of the teeth, pinion gears which engage with them, one of which is extreme output, and the leading extreme gear is non-engaging and located between the ends of the gears and the coupling they are splined couplings, some of which are HMeieiT resilient elements housed in them. However, the known distribution of the load is not sufficiently known for the known drive. The aim of the invention is to improve the uniformity of the distribution of the load and the load capacity with water. To achieve this goal, elastic elements are placed in sleeves arranged between the ends of the napi of the drive and driving gears, except for pairs. input and output gears. In addition, an axial threaded hole is made in one of the gears connected to the clutch, which has an elastic element, and the drive is equipped with a screw placed in the adapter and interacting with the elastic element. The drawing shows the proposed drive, a General view. The drive contains two pairs of coaxial helical gears 1, 2 and 3, 4, which have pairs of opposite teeth that are in engagement with output gears 5-8. Gears 3 and 4, 5 and 6 are mounted independently in bearings movably in the axial direction and are interconnected to each other and to gears 2 and 7 by the spline ™ couplings 9-11. The input gear 1 is driven by a gearbox (not shown), and the output gear 8 is connected to a worm 12. The pairs of gears 1, 2 and 7.8 are fixed axially and made integral with the shafts. Gears 1, 4, 6 and 7 have the right direction of the teeth, the rest are left. Between the input gears 3 and 4 inside the splined coupling 9 and between the output gears 5 and 6 inside the coupling 10, elastic elements 13 are installed, made in the form of cup springs . In the threaded hole of the extreme inlet

шестерни 4 ввинчен винт 14, который своим торцом упираетс  в упругий элемент 13.gear 4 is screwed by a screw 14, which rests with its end on an elastic element 13.

При работе экструдера на шестерни 3, 4 и 5,6, которые вращаютс  в направлении , указанном стрелкой, действуют осевые усили  в зацеплении,сжимающие упругие элементы 13. Б хагода1р  симметричному расположению упругих элементов относительно потоков мощности, пары подвижно установленных шестерен 3, 4 и 5, 6 нагружены одинаковыми крут щими моментами и, перемеща сь и сжима  упругие элементы 13, они преодолевают одинаковые силы трени  в ишицевнх соединени х,When the extruder operates, gears 3, 4, and 5.6, which rotate in the direction indicated by the arrow, are engaged in axial forces in engagement, compressing elastic elements 13. In a symmetrical arrangement of elastic elements relative to the power flows, pairs of gears 3, 4 and 5, 6 are loaded with identical torques and, moving and compressing the elastic elements 13, they overcome the same frictional forces in the artificial joints,

В результате неравенство осевых усилий всех шестерен и, следовательно , неравномерность распределени  крут щего момента сводитс  к минимуму , перегрузка наход щейс  в наиболее неблагопри тных услови х шестерНи снижаетс . За счет этого может быть повышен передаваемый крут щий момент.As a result, the inequality of the axial forces of all gears and, consequently, the uneven distribution of the torque moment is minimized, the overload of the gears under the most unfavorable conditions is reduced. Due to this, the transmitted torque can be increased.
