    Abstract: Hybrid Shaft Bearing, Wind Generator Comprising a Hybrid Shaft Bearing, Use of the Hybrid Shaft Bearing and Method of Operating the Hybrid Shaft Bearing. A hybrid shaft bearing (20), a wind generator comprising this hybrid bearing (20), use of the hybrid bearing (20) and a method of operating the hybrid bearing (20) is provided. The hybrid shaft bearing (20) comprises a hydrodynamic journal bearing (22) and a rolling bearing (24). Both bearings (22, 24) cooperate with a support structure (26) and rotatably support a shaft (28). To avoid contact between the sliding surfaces (73, 75) of the hydrodynamic bearing (22) the auxiliary rolling bearing (24) carries the load at low speed, e.g. during start-up and shut-down periods, by ensuring a minimum lubricating gap (71). The hydrodynamic bearing (22) takes over the bearing load when a certain speed of rotation is reached. Active supply of lubricant to operate the journal bearing (22) as hydrostatic bearing at low speed is not required. The bearings (22, 24) may be arranged in paralel or in series.

    Abstract: A bearing assembly includes an outer race having an inner surface defining a concave contour and an inner race positioned in the outer race. The inner race has an inner surface defining a bore therethrough and an outer surface defining at least one groove circumscribing the outer surface. A plurality of rolling elements is rollably located in the groove and is in rolling contact with the inner surface of the outer race. A lubricious liner has an inner liner-surface and an exterior liner-surface, the exterior liner-surface being disposed on the inner surface defining the bore. The lubricious liner has a modulus of compression of a magnitude sufficient to allow misalignment of the inner liner-surface relative to the exterior liner-surface in response to a force applied thereto.

    Abstract: A cross for a universal joint includes a body including an outwardly extending trunnion and a bearing cup mounted on the trunnion. A thrust washer is disposed between the trunnion and the bearing cup. The thrust washer includes an outer edge portion, a spacer portion that extends from the outer edge portion and is curved in cross sectional shape, a spring portion that extends generally radially inwardly from the spacer portion and is shaped generally in the form of a hollow cone, and an inner lip portion that extends inwardly from the spring portion. The thrust washer absorbs thrust loads that occur between an outer end surface of the trunnion and an inner surface of a closed end of the bearing cup and takes up any axial looseness therebetween.
