Description

Изобретение относитс  к уплотнительной технике.This invention relates to a sealing technique.

Известны торцовые уплотнени  с промежуточными кольцами, центровка которых производитс  по валу или корпусу с помощью подшипников качени .Mechanical seals with intermediate rings are known, which are centered on the shaft or the housing by means of rolling bearings.

Цель предлагаемого уплотнени  - уменьшение мош,ности трени  и устранение дополнительного износа колец.The purpose of the proposed compaction is to reduce the mosquito fatigue, friction and eliminate additional wear of the rings.

Дл  этого на торцах промежуточного кольца установлены концентрично валу посто нные магниты, прит гиваемые к магнитам, расположенным на корпусе.For this, at the ends of the intermediate ring, permanent magnets are mounted concentric to the shaft, which are attracted to the magnets located on the housing.

На чертеже показано предлагаемое уплотнение , разрез.The drawing shows the proposed seal slit.

Уплотнение состоит из уплотн емого валаThe seal consists of a sealed shaft.

I,корпуса 2, неподвижных дисков 3 и 4, в которых установлены магниты 5 и 6. Промежуточное кольцо 7 расположено между неподвижными 8 и враш:ающимис  9 уплотнительными кольцами. На промежуточном кольце 7 установлены посто нные магниты 10 иI, bodies 2, fixed disks 3 and 4, in which magnets 5 and 6 are mounted. Intermediate ring 7 is located between fixed 8 and vras: 9 sealing rings. Permanent magnets 10 and 10 are mounted on the intermediate ring 7.

II.Кольца уплотнени  прижимает пружина.II.Ring seal presses the spring.

Уплотнение работает следующим образом. При вращении вала 1 промежуточное кольцо 7 вращаетс  с половинной скоростью вала . Центровка промежуточного кольца 7 производитс  магнитным полем. При этом магниты 10 и 11 прит гиваютс  к магнитам 5 и 6. Дл  устойчивой центровки важно, чтобы ось магнитного пол  совпадала с осью вала. Таким образом, введение магнитного пол Seal works as follows. When the shaft 1 rotates, the intermediate ring 7 rotates at half the speed of the shaft. The centering of the intermediate ring 7 is produced by a magnetic field. In this case, the magnets 10 and 11 are attracted to the magnets 5 and 6. For a stable centering, it is important that the axis of the magnetic field coincides with the axis of the shaft. Thus, the introduction of a magnetic field

исключает трение промежуточного кольца 7 о вал 1 и корпус 2.eliminates friction of the intermediate ring 7 about the shaft 1 and the housing 2.

Предмет изобретени Subject invention

Торцовое уплотнение, в корпусе которого установлены подвижное и неподвижное кольца трени , между которыми помещено промежуточное кольцо, отличающеес  тем, что, с целью уменьшени  трени , на торцах промежуточного кольца установлены концентрично валу посто нные магниты, прит гиваемые к мaгнитa, расположенным на корпусеA face seal, in the case of which a movable and stationary friction rings are installed, between which an intermediate ring is placed, characterized in that, in order to reduce friction, permanent magnets attached to the magnet are mounted concentrically on the ends of the intermediate ring.
