Изобретение относитс  к машиностроению.The invention relates to mechanical engineering.

Известно бесшпоночное соединение вала со ступицей, содержащее кольцевую герметичную полость, расположенную между валом и ступицей и сообщающуюс  с источииком подачи жидкости под давлением с ло мощью канала, внутри которого расположен обратный клапан.A keyless shaft connection to a hub is known, which contains an annular hermetic cavity located between the shaft and the hub and communicating with a source of fluid supply under pressure with the channel through which the check valve is located.

Однако известное соединение недостаточно надежно, требует большего давлени  жидкости .However, the known compound is not reliable enough, it requires more fluid pressure.

Цель изобретени -повышение надежности соединени  вала со ступицей.The purpose of the invention is to increase the reliability of the connection of the shaft with the hub.

Это достигаетс  тем, что соединение -снабжено двум  втулками, концентрично расположенным .и одна относительно другой и соединенными сваркой, образу  герметичную полость , причем одна из втулок жестко соединена с валом, например, гор чей посадкой.This is achieved by the fact that the joint is supplied with two bushings concentrically located one with the other and joined by welding to form an airtight cavity, one of the bushings being rigidly connected to the shaft, for example, with a hot fit.

На чертеже схематически изображено предлагаемое соединение.The drawing schematically shows the proposed connection.

Бесшпоночное соединение вала со ступицей содержит вал 1 и ступиду 2, между которыми вмонти1рОвана кольцева  герметична  камера, образованна  герметично сваренными охватывающей 3 и охватываемой 4 втулками. Герметична  «амера при этом прочно соединена с валом, например, путем гор чей посадки . Дл  подвода рабочей жидкости герметична  -камера снабжена обратным клапаном 5, установленным в канале 6.The keyless connection of the shaft with the hub contains shaft 1 and step 2, between which there is a built-in annular sealed chamber formed by hermetically welded female 3 and covered 4 bushes. At the same time, the chamber is tightly connected to the shaft, for example, by means of a hot fit. For supplying the working fluid, the sealed chamber is equipped with a check valve 5 installed in the channel 6.

Соедин етс  вал 1 со ступицей 2 подачей под давлением в герметичную камеру через обратный клапан 5 рабочей жидкости, под действием которой происходит упруга  деформац и  охватывающей втулки 3 и ступицы 2 и прочное их соединение за счет получаемого при этом нат га.The shaft 1 is connected to the hub 2 by applying pressure into the hermetic chamber through the non-return valve 5 of the working fluid, under the action of which an elastic deformation occurs and the female bushes 3 and the hub 2 and their strong connection due to the tension obtained.

Рассоединение герметичной камеры со стуттицей производитс  стравливанием рабочей жидкости 1ИЗ камеры через 1клапан 5.Disconnection of the sealed chamber with the stuttice is performed by bleeding the working fluid 1 of the chamber through 1 valve 5.

Предмет изобретени Subject invention

Бесшпоночное соединение вала со ступицей, содержащее жольцевую герметичную полость, расположенную между валом и ступицей и сообщающуюс  с источником подачи лсидкости под давлением с помощью канала, внутри -которого расположен обратный клапан, отличающеес  тем, что, с целью повышени  надежности соединени , оно снабжено двум  втулками, концентрично расположенными одна относительно другой, соединенными сваркой и образующими -герметичную -полость , причем одна из втулок жестко соединена с валом, например, гор чей посадкой.A keyless shaft-to-hub connection containing a zholtsev sealed cavity located between the shaft and the hub and communicating with the source of pressure under pressure via a channel inside which is a non-return valve, characterized in that it is equipped with two bushings to increase the connection reliability. concentrically located one relative to another, connected by welding and forming a гер-hermetic ол-cavity, and one of the sleeves is rigidly connected to the shaft, for example, by a hot fit.
