Fey sealing rings utilise a low contact multiple labyrinth with very little gap width This special design produces little friction reducing internal heat and wear as well as providing outstanding sealing characteristics. The centrifugal force is however sometimes insufficient to prevent foreign matter being drawn further into the passageway upon relative rotation between the two members of the seal. It is a split-pillow (plummer) design consisting of a cap and base. 2 is a cross sectional side elevation of the seals of FIG. The housing 70 is shaped to form two annular tongues 75, 76 and the end cover 71 is shaped to form a single annular tongue 77 which engages between the two tongues 75, 76 and co-operates therewith to form the annular labyrinth passageway 72. At least a portion of the passageway is defined by frusto conical surfaces on the annular tongues arranged to exert centrifugal force on any foreign matter in the passageway upon relative rotation between the two members so as to urge the foreign matter towards the outer end of the passageway. The two pieces interlock to effectively seal out the majority of contaminants while holding in the lubricant or process fluid. Lip seals are usually made of nitrile rubber or polymer material, although felt seals are still commonly used. The seal consists of three parts which are made of sheet steel and are pressed together. Sudarsan Engineering Industries. In use, upon rotation of the housing 85, any foreign matter in the flared portions 92, 93, 94 will be circulated around the associated flared portion due to the frictional resistance with the housing, and will be urged radially outwards by centrifugal force. FIG. This construction has the advantage that the flange 60 shrouds the open end of the passageway 50, particularly when the end cap assembly is operating with its axis horizontal.

Support video describing how to dismantle the labyrinth seal on a FRITSCH Universal Cutting Mill PULVERISETTE 19. 11 and 12 so that foreign matter in the labyrinth passageway is urged towards the outer end of the passageway by both centrifugal force and the squeezing action between the diverging walls of the relevant portion of the passageway. It is important that labyrinth seals should be periodically lubricated to ensure that there will always be clean grease inside the labyrinth. up to the ratings specified in the SKF General Catalogue, non-rubbing seals must be used, mainly gap type or labyrinth seals. Want to learn more about what is driving change in the engineering world? About 8% of these are Housings, 59% are Material Handling Equipment Parts. A labyrinth seal is a seal which creates a complicated path for liquids to pass through, making it challenging for liquids to cross the barrier created by the seal because they have difficulty making their way all the way through the labyrinth. Labyrinth seals . The housing and end cover have features common to that of the housing and end cover of FIG. The permissible misalignment of labyrinth seals is normally around 0.5 degrees. All rights reserved. Since the maximum operating temperature that the seal materials and the grease in the bearing can withstand is around 100 –C, the peripheral speed at the seal contact point, i.e. For the Pop Release bearing unit, this takes place at the same time as lubrication of the bearing through the grease nipple mounted on the bearing housing. Fey labyrinth sealing rings are used as sealing elements for both rotating and static applications. 11 and 12 comprises a housing 130 fitted with a ball bearing 11, and an end cover 131 which co-operates with housing 130 to form an annular labyrinth passageway between two annular tongues 132, 133 on the housing interleaved with two annular tongues 134, 135 on the end cover. 9, FIG. The device of the invention may comprise annular tongues which are spaced from one another in the axial direction, in which case the outer end of the passageway is the axially outer end remote from the components being sealed, or the annular tongues may be spaced from one another in the radial direction, in which case the outer end of the passageway is the radially outer end.

The SKF Taconite Seal is supplied with a grease fitting for the grease purging of the labyrinth. In use, any foreign matter which enters the narrow passageway 50 through the open end 51 will normally come in contact with the wall of the passageway defined by the housing 10 and, upon rotation of the housing, the frictional resistance between the foreign matter and the housing will cause the foreign matter to circulate around the annular passageway 50. It is believed that the reason why foreign matter is drawn into the labyrinth passageway when the walls diverge in a direction leading away from the outer end is that the tongues of a labyrinth seal are not always exactly co-axial, due to manufacturing tolerances, and that any such eccentricity, combined with diverging walls in a direction away from the outer end of the passageway, cause the labyrinth seal to act in effect as a positive displacement pump drawing foreign matter along the passageway away from the outer end thereof. One piece, known as the stator, is affixed to the machine and remains stationary. SKF non-contact labyrinth seals provide an ideal solution. The present invention consists in so designing the labyrinth seal that, upon relative rotation between the seal members, at least part of the labyrinth passageway acts as a centrifugal pump which drives any foreign matter along the passageway in the direction of the outer end of the passageway, despite any slight tilting of the seal members due to deflection of the supporting shaft. Labyrinth seals are a non-contact seal that makes a tougher path for contaminants to enter while operating with little or no friction. The annular recess 45 between the tongue 38 and the cylindrical flange 39 on the cover is filled with grease for lubricating the bearing, the seal 13 preventing escape of the grease through the labyrinth. 12. As a result, the maximum permissible rotational speed of the bearing is also restricted. 128,894, filed Mar. The radially inner wall of the open end 51 of the passageway may then be formed with a cylindrical surface 62 on the tongue 36 of the end cover as shown in FIG. Location. The highest admissible peripheral speed of a radial lip seal is normally around 7-8 m/s. The tongue 106 has a cylindrical surface 107 which co-operates with a frusto-conical surface 108 on the tongue 104 to form a portion 109 of the passageway in which the walls diverge in a direction leading towards the outer end of the passageway. The radially outer surface 120 of the tongue 103 on the housing will of course be concentric with respect to the shaft 73 since this surface supports the end of the flange 19 when the flange and the end of a roller tube are swaged onto the housing. This non-contact seal has no wearing parts and eliminates fretting caused by conventional lip seals. The labyrinth seal between the housing and the end cover is shown more clearly on a larger scale in FIG. SKF Taconite seals are designed for use with SAF series pillow blocks and is used to retain lubricant and protect against contamination. FIG. In the end cap bearing assembly of FIG.

The centrifugal force on foreign matter in portion 58 will urge the matter in the direction leading to the portion 53 in which the foreign matter will be thrown to the open end 51 as described above. Mounted bearings combine a bearing mounted inside a housing unit. LABYRINTH SEALS (LO) Labyrinth seals are made up of a single metal ring component that interconnects with the grooves in the housing to form a labyrinth gap. TS 40, SKF, Labyrinth seal Metric, Seal, Labyrinth seals. The radially outer portion 53 of the passageway 50 adjacent the open end 51 is defined by a frusto-conical surface 54 on the tongue 26 and a frusto-conical surface 55 on the tongue 36, so that the radially outer portion 53 is flared radially and axially outwards relative to the axis of the end cap assembly. The ball bearing 11 comprises an outer bearing ring 30, an inner bearing ring 31 and balls 32 in rolling engagement with grooved tracks on the rings 30, 31 so that the bearing is capable of resisting radial forces and axial forces in both directions. This purges the labyrinth of contaminants and helps block the entrance of contaminants. Such grooves 64 or ridges 65 increase the tangential coefficient of friction between foreign matter and the tongue 26 on the housing without increasing the axial coefficient of friction values. In order to use rolling bearings at higher speeds, i.e. The benefit of this type of seal is that it is very effective in preventing dirt from entering the bearing.
