Description

(54) УПЛОТНЕНИЕ ВАЛА(54) SHAFT SEAL

Изобретение касаетс  машиностроени .The invention relates to mechanical engineering.

Известны уплотнени  вала, преимущественно из пластических полимерных материалов , на корпусе которых выполнен уплотн ющий выступ с уплотнительной кромкой, на стороне, противоположной уплотнитепьной кромке которого, в кольцевой проточке установлен пружинный элемент.The shaft seals are known, mainly of plastic polymeric materials, on the casing of which a sealing lip with a sealing edge is made, on the side opposite to the sealing edge of which a spring element is installed in an annular groove.

Предложенное уплотнение вала отличаетс  от известного тем, что, пружинный элемент выполнен в виде незамкнутого плоского пружинного кольца, у которого наружный диаметр эксцентричен внутреннему. Такое конструктивное выполнение вала повышает надежность уплотнени .The proposed shaft seal differs from the known one in that the spring element is made in the form of a non-closed flat spring ring, in which the outer diameter is eccentric to the inner one. Such a structural embodiment of the shaft increases the reliability of the seal.

На чертеже .изображен вид уплотнени  с торца; разрез Л-А одного варианта и( разрез А-А второго варианта.The drawing shows a view of the seal from the end; section A-A of one variant and (section A-A of the second variant.

Уплотнение состоит из корпуса 1 на котором выполнен уплотн ющий выступ 2 с уплотнительной кромкой 3, кольцевой проточки 4, в которую установлен пружинныйThe seal consists of a housing 1 on which a sealing protrusion 2 is made with a sealing lip 3, an annular groove 4 in which a spring-loaded

элемент S. Такое конструктивное выполнение уплотнени  обеспечивает равномерное поджатие кромки 3.element S. Such a structural design of the seal ensures uniform compression of the edge 3.

Равномерное обжатие осуществл етс  за счет выполнени  пружинного элемента 5 в виде незамкнутого плоского пружинного |кольца, у которого наружный диаметр экс- центричен внутреннему.Uniform compression is accomplished by making the spring element 5 in the form of an open flat spring ring, in which the outer diameter is eccentric to the inner.
