![]() Shaft seal
专利摘要:
A shaft seal assembly for installation and operation in an annular space defined between first and second relatively rotatable machine components. The shaft seal assembly has a housing adapted to engage the first machine component, a runner ring surrounded by the housing and adapted to engage the second machine component, a chamber defined by the housing and bounded by the runner ring and a sealing body disposed in the chamber. The sealing body is an incompletely polymerized elastomer fully polymerizable subsequent to the installation by heat generated during operation of the first and second machine components. 公开号:SU1304754A3 申请号:SU843687462 申请日:1984-01-12 公开日:1987-04-15 发明作者:Дойринг Ганс 申请人:Гетце Аг (Фирма); IPC主号:
专利说明:
The invention relates to mechanical engineering, in particular to shaft seals. The aim of the invention is to increase durability and compaction by eliminating damage to the sealing element in working condition by reducing initial friction losses during the starting period. Figure 1 shows the sealing assembly in the assembled state; figure 2 - sealing unit, having partially educated) polymer mesh, in the installation position, Shaft sealing unit 1 is used as a seal, which is heavily affected by bearing pollution 2 dp of a wheel of 3 tons of gacha (not shown. The optional shaft component I consists of a housing 4, which is connected without rotation to the bearing housing 5 a cross sectional profile of an angular mounting ring 6, which is held in the housing 5 with a positive fit, of a sealing cuff having two sealing tabs 7 and 8, one of which (sealing tab 7) is under the the spring loaded y, spring loaded sealing tongue 7 is located in the direction of the medium to be sealed, i.e. in the direction of the bearing 2, while spring loaded sealing tongue 8 serves as a clean seal from contamination. The axially extending knee 10 of housing 4 is conically constricting in the direction of the adjusting ring. The radial protrusion 11 of the angular adjusting ring 6 is radially bent in the plane of the conical bend 10 axially on the limb The movable part 12, which passes into another area, is axial to the bend 13 of the housing 4, which cooperates with the bearing housing 5. The connection with the geometric closure between the mounting ring 6 and the housing 4 is made by means of the axial bending 13 of the housing 4 being bent spring tongs 14, which in the form of a lock act in the assembled state in the axial direction behind the radial protrusion 1i. Sealing assembly I of the shaft is shown in the drawing in embedded state five 0 50 nii. In the space 15, limited between the elbows 10, 13 of the housing 4 and the radial protrusion 11, there is a sealing ring 16 consisting of nitridbutadiene rubber, which was inserted into the space 15, in the state when the polymer network was not fully formed. Due to the temperature effect during the start-up period, the sealing body completely forms the polymer mesh and takes its final shape both due to this and due to the relative movement between the sealing ring 16 and the radial protrusion 11. Thanks to the sealing ring acting as the axial spring 16 with an incompletely formed polymer mesh, the initial loss of friction is reduced and a labyrinth gap of 17 m is formed corresponding to the mounting situation of Fig. 2 The seal ring 16 and the radial protrusion 11 are offset, with tolerances and a predetermined mounting position being compensated. In figure 2, the sealing assembly is represented in the mounting position. The radial protrusion 1 of the adjusting ring 6 is bent approximately axially in the direction of the body 4 of part 12. To form a convexly curved cross-sectional profile 18 bent at an angle in the direction of the profiled axial bend 13 of the body 4. At the same time, the axial bend 13 in the area of its free end 9 is bent radially in the direction of the mounting ring 6, Thanks to these measures, the mounting ring 6 for transport and installation is held in the housing 4 with a geometric locking. The sealing ring 16 5 with only a partially formed polymer mesh is located in the space 1 5 and, under axial prestressing, fits exclusively to the convexly bent part of the radial protrusion 11. Here the mounting clearance is also regulated, after the sealing ring 16 has completely formed the polymeric mesh, final form. 0 five 0 25 0 55
