Abstract: A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.

Abstract: A bearing cap (1) is attached to a bulkhead (22) of a cylinder block (21) made of a light metal through a pair of bolts (24). The bearing cap (1) has a frame (2) made of an iron-based metal and a cast light-alloy part (3). The frame (2) has a pair of pillar parts (9) through which the bolts (24) extend and a circular-arc-shaped arch section (10). At high temperatures, the span of the pair of the bolts (24) increases due to thermal expansion of the light-alloy material, and the pair of the pillar parts (9) expand. This causes the middle part of the arch section (10) to shift upward, thereby suppressing an increase in bearing clearance.

Abstract: A wind turbine, including a support structure and a thrust bearing having a bearing pad which includes a piston and which is movably connected to the support structure, a spring element which is configured to resiliently support the bearing pad relative to the support structure, wherein a pad portion of the bearing pad and/or the bearing pad itself is configured to tilt and to move translationally relative to the support structure, and wherein a gap is provided between the piston and the support structure. The piston limits the movement of the bearing pad. Thus, reliable and well defined movement limits are provided. Furthermore, a broad spectrum of spring parameters is available since the movement may be restricted by the piston and not necessarily be the spring element.

Abstract: A structure and method of operation of a journal bearing is disclosed that minimizes contact of the shaft with the sleeve during start up and slow down of the rotation of the shaft relative to the sleeve, or vice versa. The bearing assembly includes a gravitational load reduction mechanism with magnets disposed on the sleeve and on the shaft in alignment with one another. The magnet(s) on the shaft interacts with the magnet(s) disposed on the sleeve to provide a force against the pressure of the shaft towards the sleeve generated by gravity acting on the rotating component. The magnets enable centering of the rotating component within the stationary component during low rotation and non-rotation. This prevents rubbing of the rotating journal bearing component surfaces, e.g., sleeve, against the stationary journal bearing component, e.g., shaft, during assembly, ramp-up, and coast-down when the journal bearing fluid provides minimal or no bearing centering capability.

Abstract: The invention relates to a method and an arrangement related to a rotator, especially for a work tool supported by an arm, whereby the rotator (10) comprises a stator (20) and a rotor (30). A fastening ring (50) for the attaching of a work tool is separately journalled (D) relative to the stator (20) independently of a bearing (B, C) between the stator (20) and the rotor (30). A driver (80; 180; 280) is used to transfer the rotational movement of the rotor (30) to the fastening ring (50).

Abstract: A tolerance ring has a band with outwardly extending corrugated protrusions forming waves that engage an outer surface of a shaft. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to a bore of a housing to assist during assembly.

Abstract: A sleeve housing of a bearing mechanism according to a preferred embodiment of the present invention includes a cylindrical portion arranged to cover outer circumferences of a sleeve and a plate portion, and a bottom portion arranged to close a lower portion of the cylindrical portion. The bottom portion includes a plurality of projecting portions arranged in a circumferential direction in an upper surface of the bottom portion. Each projecting portion is arranged to project upward to be in contact with a lower surface of the sleeve. Each of the projecting portions and the plate portion are arranged radially opposite each other. At least a portion of an adhesive is arranged to exist between an outer circumferential surface of the sleeve and an inner circumferential surface of the cylindrical portion.

Abstract: A plain bearing assembly of a rotational element on a bearing bolt includes a bearing bolt, a bearing sleeve, which is non-rotatably mounted on said bolt and which comprises a first radial bearing surface formed on its outer periphery, and a rotational element which is rotatably mounted on the bearing sleeve and which is mounted on the first radial bearing surface via a second radial bearing surface in such a way that it can slide. Axial bearing washers, which project radially beyond the bearing sleeve, are secured to both end faces of the rotational elements. The washers run against axial bearing surfaces of the bearing sleeve, and axial flanks of the bearing sleeve form axial bearing surfaces for the axial bearing washers.
