Abstract:
A radial shaft seal assembly (10) for establishing a seal to separate an oil side from an air side of the assembly is provided. The assembly includes a metal case (12) having a cylindrical wall (14) with an annular leg (22) extending radially inwardly from the cylindrical wall. A primary seal lip (28) is operably attached to the metal case. The primary seal lip is configured for running contact with a rotatable shaft member (48) to separate the oil side (O) from the air side (A). A debris exclusion member (30) including an annular retainer (32) with a plurality of elongate bristles (34) fixed thereto is fixed to one of the rotatable shaft member (17) or the metal case, wherein the bristles extend radially free ends (54), with a clearance gap (G) being established between the free ends and the other of the rotatable shaft member and the metal case.

Abstract:
A turbocharger (100) includes a two-piece thrust collar that includes inner and outer portions (136 and 138) disposed around a rotatable shaft (120). The inner portion (136) is engaged with a bushing disposed in and connected to the center housing (106) by a retainer (134). The outer portion (138) is disposed adjacent the inner portion along the rotatable shaft (120) and connected to the rotatable shaft (120) such that it rotates therewith. The outer portion forms an annular channel (144) that extends in a radial direction relative to the rotatable shaft (120) and peripherally around the shaft (120). An oil deflector (200) is connected to the compressor back-plate (108) and includes a base flange (202) and a raised portion (204) disposed at least partially over the annular channel (144).
Abstract:
The invention relates to a receptacle comprising a shaft housing for guiding a shaft through a wall into the receptacle interior, the shaft being mounted in the shaft housing via a shaft guide part by way of ball bearings and being sealed relative to the shaft housing by means of seals. The invention is characterized in that: the shaft housing has the form of an annular cap towards the receptacle interior and has an inner wall spaced apart from the outer wall, said inner wall being connected to the outer wall of the shaft housing via an inner end face facing the receptacle interior; the shaft guide part, at its end facing the receptacle interior, has an outer surface which defines a gap relative to the inner wall of the shaft housing; the shaft guide part has an annular wall spaced apart from and parallel to its outer surface, which annular wall extends over the free end of the inner wall of the shaft housing in the form of a cap; the annular wall is sealed in relation to the inner wall of the shaft housing on the one end and in relation to the outer wall of the shaft housing on the other end by at least one seal each; and the shaft guide part is mounted in the shaft housing by means of a first ball bearing in the form of a radial ball bearing and by means of a second ball bearing in the form of an axial ball bearing.
Abstract:
In summary, the invention relates to a seal arrangement for non-contact sealing of anti-friction bearings, in particular for sealing anti-friction bearings in conveyors, machine tools, pumps, electric motors and the like. More specifically, the invention relates to an improvement of the arrangement of non-contact fluid-collecting labyrinth seals which perform a sealing function, such that firstly no lubricating oil can escape from the anti-friction bearing side (35) and secondly no water and contaminant can enter from the atmosphere side (36). The seal arrangement of the invention consists of a three-piece pre-assembled labyrinth seal (1), of which at least one sealing element (8) is arranged together with the surrounding, stationary machine part (2) and at least one sealing element (9, 16) is arranged on a rotatable machine part (6). One core advantage of this invention consists in that, if the seal arrangement according to the invention is used, a satisfactory and effective sealing result is achieved despite somewhat severe surging flooding to the sealing elements which occurs.
