摘要:
A resilient annular bearing seal (22,24) having an inner surface defining a central opening, an outer surface defining the seal outer periphery, and first and second side walls between the inner and outer surface and on opposite sides of the seal, the seal further having a circumferentially continuous sealing lip (30,32) extending axially outwardly from the first side wall, the first side wall having a relieved portion (34,36) adjacent to the sealing lip for receiving the sealing lip. The seal may include a sealing shoulder (26,28) adjacent to the outer surface and the first side wall. The seal may also include at least one lip (52,54) extending radially inwardly from the inner surface, and a sealing shield (56,58) adjacent to the first side wall and the inner surface and extending both radially inwardly and axially outwardly. Also, a bearing assembly having an annular outer race (6); an annular housing (10) surrounding the outer race and including side flanges (19,20) extending radially inwardly; an inner race (4) coaxially disposed relative to the outer race; and the annular seals (22,24) of the present invention mounted on either side of the inner bearing race and contacting the outer bearing race, the sealing lips of the seal contacting the housing side flanges.

When assembling an outer ring into a rolling bearing unit with a retainer plate, a retainer plate 7a in which large-diameter sections 21 are provided at plural locations in the circumferential direction of a support hole 13a is used, and with a small-diameter stepped section 9a of the outer ring 5a fitted inside this support hole 13a, a punch 23 presses parts of the circumferential edges of the large-diameter sections 21 of the side surface in the axial direction of the retainer plate 7a toward a step surface that exists between the outer-circumferential surface of the outer ring 5a and the base section in the axial direction of the small-diameter stepped section 9a and plastically deforms the parts of the circumferential edges of the large-diameter sections inward in the radial direction to form engagement protrusions, while at the same time, the engagement protrusions are engaged with an engagement groove 12a that is formed around the outer-circumferential surface of the small-diameter stepped section 9a.

The invention relates to an engine bearing assembly, in particular for a dry-running compressor that is ready for operation even at low ambient temperatures. Said engine (crankshaft) bearing assembly comprises bearing points designed as standard rolling-element bearings and provided with contactless rolling-element bearing seals, both at the bearing point without crankshaft feed-through and at the bearing point having a crankshaft feed-through. In particular, the engine bearing assembly according to the invention has the advantage that all seals in the direction outward from the crankcase are designed in such a way that a vacuum arising in the crankcase can suck grease fillings from the bearings and seal spaces into the crankcase.

Support for rolling bearings (1) comprising a first inner annular shell (3) made of metal and intended to be mounted on the outer surface of a rolling bearing, a second outer annular shell (5) made of metal, concentric with said first inner annular shell and external thereto and intended to be mounted on the surface of the bearing seat, and an intermediate elastomeric member (7) provided between said inner and outer shells and fixed thereto. Thanks to the configuration of the invention, any relative movement between the metal shells (3, 5) and the intermediate elastomeric member (7) is prevented, while allowing movement of the first inner shell (3) and the second outer shell (5) relative to each other, so that the radial and axial stiffness of the support only depends on the mechanical properties and geometry of the intermediate elastomeric member (7).
摘要:
Die Erfindung betrifft eine Lageranordnung (1) umfassend ein in einem anschraubbaren Gehäuse (2) aufgenommenes Wälzlager (5) mit einem Außenring, einem Innenring (7) sowie einer Vielzahl von Wälzkörpern (8), die zwischen dem Außenring (6) und dem Innenring (7) um eine Rotationsachse (9) des Wälzlagers (5) abrollen, wobei entweder der Außenring (6) oder der Innenring (7) gegenüber dem Gehäuse (2) drehfest festgelegt ist und der jeweils andere Lagerring gegenüber dem Gehäuse (2) drehbar ist. Erfindungsgemäß ist vorgesehen, dass ein Messaufnehmer (10) drehfest mit dem Gehäuse (2) verbunden ist und dass ein mit dem Messaufnehmer (10) zusammenwirkender Messgeber (11) drehfest mit dem gegenüber dem Gehäuse (2) drehbaren Lagerring verbunden ist bzw. ein mit dem Messaufnehmer (10) zusammenwirkender Messgeber (11) durch den gegenüber dem Gehäuse (2) drehbaren Lagerring gebildet wird.
