Abstract

Использование: устройство может использоватьс  в судовом машиностроении дл  уменьшени  утечек рабочей жидкости гидросистем. Сущность изобретени : масловвод содержит корпус 1 с каналами дл  подвода масла и слива 3 утечек, а также уплотнени  маслоподвод щего канала, каждое из которых состоит из укрепленной на вращающемс  валу 4 втулки и подпружиненных е осевом направлении уплотнитель- ных плавающего 8 и опорного колец 7. Контактирующие уплотнительные поверхности 9 втулок 6 и плавающих колец 8 вы- полнГен ы коническими и ориентированы вершинами конусов в маслоподвод щему каналу 2, причем оси конусов совпадают с осью вращени  вала. Плавающие кольца зафиксированы от вращени  и подпружинены в направлении маслоподвод щего канала. 1 ил.Usage: the device can be used in marine engineering to reduce hydraulic fluid leakage. SUMMARY OF THE INVENTION: an oil inlet comprises a housing 1 with channels for supplying oil and draining 3 leaks, as well as seals for the oil supply channel, each of which consists of a sleeve mounted on a rotating shaft 4 and axially spring-loaded floating o-rings 8 and support rings 7. The contacting sealing surfaces 9 of the bushings 6 and the floating rings 8 are conical and oriented by the vertices of the cones in the oil supply channel 2, the axes of the cones coinciding with the axis of rotation of the shaft. The floating rings are rotationally fixed and spring-loaded in the direction of the oil supply channel. 1 ill.
