Description

(54) УПЛОТНИТЕЛЬНО-ОПОРНЫЙ УЗЕЛ ВАЛА
того, часть магнитного потока, создаваемого посто нным магнитом, идет через наружную обойму подшипника, шарик и внутреннюю обойму подшипника. В месте контакта шарика с обоймами возникает градиентное магнитное поле, под действием которого магнитна  жидкость, вт гива сь, образует смазывающую пленку вокруг шарика.
Применение указанного уплотнени  позвол ет значительно снизить габаритные и весовые характеристики устройства, использовать подшипники обычного исполнени  в вакууме, агрессивной, биологической и других газовых средах, предотвратить нежелательные вибрации вала при высоких скорост х вращени , что повышает работоспособность уплотнени  и улучшает его механические характеристики.
