Description

наклонными поверхност ми к соответствующим поверхност м радиальных храповых зубьев 3 на упорных дисках 4, установленных на ступицах 5 ведомых полумуфт 1. На обращенных друг к другу зубчатых поверхност х ведомых полумуфт 1 и упорных дисков 4 выполнены канавки 5 дл установки прил имных пружин 7. Между упорными дисками 4 установлена ведуща полумуфта 8, на ступице 9 которой с двух сторон размещены нажимные диски 10. Ведуща полумуфта 8 имеет гнезда И, выполненные в виде радиальных пазов, дно которых сферическое, причем в сечении перпендикул рном оси пазы имеют форму пр моугольника. Больща стенка 12 паза наклонена к противоположной стенке под углом ее, равным углу б заклинивани . На торцах нажимных дисков 10, обращенных к ведущей полумуфте 8, так же имеютс радиальные пазы 13, в которые вставлены сухари 14. Сухари 14 имеют гнезда со сферическим дном. В гнездах ведущей полумуфты 8 и сухарей 14 наход тс тела заклинивани 15, каждое из которых выполнено в виде пластины с двум сферическими противоположными торцами. Полол ение сухарей 14 в пазах налсимных дисков 10 ;реглируетс прокладками 16.inclined surfaces to the respective surfaces of the radial ratchet teeth 3 on the stop disks 4 mounted on the hubs 5 of the driven coupling halves 1. On the facing surfaces of the toothed surfaces of the driven coupling half 1 and the stop disks 4, grooves 5 are made to install the application springs 7. Between The stop half coupling 8 is installed by stop discs 4, on the hub 9 of which pressure plates 10 are placed on both sides. The leading half coupling 8 has sockets And, made in the form of radial grooves, the bottom of which is spherical, and in cross section perpendicular The axis of the grooves is rectangular. The large wall 12 of the groove is inclined to the opposite wall at an angle equal to the angle b of wedging. At the ends of the pressure discs 10 facing the leading half coupling 8, there are also radial grooves 13 into which the crackers 14 are inserted. The crackers 14 have sockets with a spherical bottom. In the nests of the leading half-coupling 8 and crackers 14 there are bodies of jamming 15, each of which is made in the form of a plate with two spherical opposite ends. The polishing of the crackers 14 in the grooves of the nacimal discs 10;

В ведущей лолумуфте 8 и на торцах нажимных дисков 10, обращенных к упорным дискам 4, имеютс отверсти 17 и канавки 18 дл подвода масла дл охлаладени муфты и удалени продуктов износа деталей муфты.There are holes 17 and grooves 18 for supplying oil to cool the coupling and remove the wear products of the coupling parts in the leading luminal coupling 8 and on the ends of the pressure disks 10 facing the stop disks 4.

Все детали прижаты друг к другу и зазоры между ними выбраны прижимной пружиной 7.All parts are pressed together and the gaps between them are selected by the clamping spring 7.

Механизм свободного хода работает следующим образом.The free wheeling mechanism works as follows.

Ведуща полумуфта 8 вращаетс в направлении , указанном стрелкой, и увлекает за собой тела заклинивани 15, которые создают распорное усилие, автоматически увеличива силу трени иа фрикционных поверхност х нажимных 10 и упорных 4 дисков.The driving half coupling 8 rotates in the direction indicated by the arrow and carries the jamming bodies 15, which create the thrust force, automatically increasing the friction force of the friction surfaces of the pressure 10 and thrust 4 disks.

Распорное усилие создаетс за счет упругих деформаций деталей муфты.The thrust force is created by the elastic deformations of the coupling parts.

При вращении ведущей полу муфты 8 в противоположную сторону распорное усилие исчезает и полумуфты расклиниваютс .When the leading half of the coupling 8 rotates in the opposite direction, the thrust force disappears and the coupling halves are wedged.
