Claims (1)

С целью надежного управления большим зазором в подшипнике в зоне уплотнения внутреннего вала гребных винтов с двумя концентрически расположенными относительно друг друга гребными валами для судов несущее уплотнительные манжеты кольцо, монтируемое в корпусе, выполнено отдельно от соединяющего уплотнение с наружным валом опорного кольца, однако соединено с ним с исключением возможности протекания жидкости с помощью эластичных кольцевых стенок, так что компенсируются изменения в зазоре между внутренним и наружным валами.In order to reliably control the large clearance in the bearing in the sealing zone of the propeller inner shaft with two propeller shafts for ships concentrically located relative to each other, the ring bearing the sealing cuffs mounted in the hull is made separately from the supporting ring connecting the outer shaft with the outer shaft, however connected to it with the exception of the possibility of fluid flow using elastic annular walls, so that changes in the gap between the inner and outer shafts are compensated.
