摘要:
A bearing arrangement for use with a structure defining an outer surface which expands and contracts inward and outward relative to the structure includes, a member having at least one inner surface to face the outer surface, and at least one protrusion extending from the inner surface, the at least one protrusion being biased toward and in contact with the outer surface and maintains contact as the structure expands and contracts.

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.
摘要:
A lightweight hybrid bearing assembly and method of making thereof is disclosed. The bearing assembly includes an inner race and an outer race radially spaced from the inner race. One or both of the inner race and the outer race have a convex bearing surface. Between the inner race and the outer race, a plurality of ceramic roller elements are received. The ceramic roller elements have a concave bearing surface that engages the convex bearing surface or surfaces. Among other things, this accommodates axial misalignment of the races relative to one another.

The bearing seal assembly (50) includes a metal shield (70) and a resilient multi-lip sealing gasket (60) secured to the metal shield. The metal shield is supported in use by an outer ring (20) of a rolling contact bearing and includes a diagonally extending central portion (72). The sealing gasket (60) provides a number of contacting lips (62-64) facing an inner ring of the rolling contact bearing. A first, main contacting lip (66) exerts a first radial load on the inner ring. A second contacting lip (62) extends from the first lip (66) and exerts a second radial load on the inner ring lower than the first radial load. A third contacting lip (64) is on the opposite side of the second lip (62) with respect to the first lip (66) and exerts a third radial load on the inner ring lower than the first radial load but greater than the second radial load.

An outer ring (21), an inner ring (22) and a roller (23) serving as a bearing component that adopts as a source material a steel ensuring a large fracture toughness value and also having an alloy element added thereto in a reduced amount and also provides sufficient wear resistance, are configured of a steel containing 0.15-0.3% by mass of carbon, 0.15-0.7% by mass of silicon, and 0.15-1.0% by mass of manganese, with a remainder of iron and an impurity, and have a raceway/rolling contact surface (21A, 22A, 23A) included in a region having a carbon enriched layer (21B, 22B, 23B) and a nitrogen enriched layer (21D, 22D, 23D). In the nitrogen enriched layer (21D, 22D, 23D) the raceway/rolling contact surface (21A, 22A, 23A) has a nitrogen concentration equal to or larger than 0.3% by mass.
摘要:
A bearing is disclosed. The bearing has an inner ring concentrically disposed with an outer ring with rotational elements therebetween adapted for allowing rotational movement of the inner ring relative to the outer ring. The outer ring has a crowned outer surface. A waveform expansion sleeve is disposed about the outer ring. The waveform expansion sleeve has a cylindrical outer surface dimensioned to be received in a bore of a bearing housing and an inner surface with a profile matching the outer ring outer surface. The waveform expansion sleeve has an undulating radial cross-section sufficient to exert radial pressure at its inner surface against the outer ring outer surface when mounted in the bore of the bearing housing to sufficiently secure the bearing in the housing. The expansion sleeve inner surface forms a seal with the outer ring outer surface when the bearing is installed in the bearing housing.
摘要:
A unit (1) for supporting the axle-shafts of go-karts provided with an annular body (12) having a variable perimeter and with a rolling bearing (20), set within the annular body (12) itself with the possibility of oscillation about an axis of adjustment (B) transverse to an axis (B) of rotation of the bearing (20) itself; a tightening system (30) being provided for tightening the support (11) on the bearing (20) and for blocking the bearing (20) itself in an operative position, and being defined by at least two sharp edges (32) (33) (36), fixed with respect to the bearing (20) and set about the axis (B) of rotation for cutting into a softer material of the concave seat (13), preventing any rotation of the bearing (20) about the axis (A) of adjustment in said operative position.
