Abstract

Использование, в области машиностроени дл передачи крут щего момента при высокой нагрузочной способности и плавность работы муфты Сущность изобретени : ведуща 3 и ведома 4 полумуфты установлены на цилиндрическом валу 1 и подпружинены одна к другой посредством пружины 5 переменной жесткости. Правым концом пружина 5 опираетс на диск 9, к которому прикреплен посто нный магнит 10 Посто нный магнит 6 закреплен на валу , а магнит 7 - на диске 8, закрепленном на вачу Посто нные магниты 6 и 10 обращены один к другому полюсами одноименной пол рности, а магниты 7 и 10 - полюсами разноименной пол рности При наступлении перегрузки полумуфты 3 смещаютс вправо, при этом пружина 5. воздейству на диск 9, перемещает его вместе с магнитом 10 в направлении магнита 6, поэтому срабатывание муфты не сопровождаетс увеличением силы сжати пружины 5 Отсутствие действи магнитных сил на полумуфту 3 позвол ет повысить нагрузочную СПОСОбнОСТЬ МУФТЫ 1 ЗП.Ф-ЛЫ, 1 ИЛUse in the field of mechanical engineering for transmitting torque at high load capacity and smooth operation of the coupling SUMMARY OF THE INVENTION: The drive 3 and driven 4 of the coupling half are mounted on a cylindrical shaft 1 and spring-loaded to one another by means of a spring 5 of variable stiffness. The right end of the spring 5 rests on the disk 9, to which the permanent magnet 10 is attached. The permanent magnet 6 is mounted on the shaft, and the magnet 7 on the disk 8, mounted on the vach. The permanent magnets 6 and 10 are facing one another with poles of the same polarity, and magnets 7 and 10 with poles of opposite polarity. When overload occurs, the coupling halves 3 are shifted to the right, with the spring 5. acting on the disk 9, moving it together with the magnet 10 in the direction of the magnet 6, so the clutch is not accompanied by an increase in the compression force of the spring 5 Otsu Corollary action of magnetic forces on the coupling half 3 allows to increase load capacity CLUTCH 1 ZP.F BACKGROUND IL 1
