Abstract:
The invention provides a drive mechanism (10) for a wiper blade that comprises: a support base (12); a drive motor (14) comprising a casing (16) and a shaft (18) having a horizontal main axis (A); means for rotationally guiding the drive shaft (18) about the horizontal axis (A), comprising a first bearing (24) for guiding the shaft (18) with respect to the base (12) and a second (26) for guiding the shaft (18) with respect to the casing (16), characterized in that the guide means comprise a third bearing (32) so as to enable the shaft (18) to be guided, and hence positioned, when mounting the motor (14) on the base (12), said third bearing not being in contact with the shaft (18) when the motor (14) is mounted on the base (12). The invention also provides a method of assembling such a drive mechanism (10).
Abstract:
Die Erfindung betrifft ein Gelenklager (1) mit einem Lagerinnenteil (2) als erstem Lagerteil mit beidseitig gegenüberliegenden Anschlusszapfen (10, 11) und mit einem Gehäuse (3) als zweitem Lagerteil, in dem das Lagerinnenteil (2) elastisch gelagert ist dergestalt, dass es mit seinen Anschlusszapfen (10, 11) zumindest teilweise aus gegenüberliegenden Durchbrüchen (14, 15) des Gehäuses (3) herausragt. Erfindungsgemäß weist das Lagerinnenteil (2) ein Mittenteil (4) mit einem Freigang (24) zum umgebenden Gehäuse (3) auf und beidseits des Mittenteils (4) schließt sich jeweils ein bezüglich einer Lagerachse (5) rotationssymmetrischer Gleitkragen (6, 7) an, der jeweils in den aus dem zugeordneten Durchbruch (14, 15) geführten Anschlusszapfen (10, 11) übergeht. Ferner sind beide Gleitkragen (6, 7) im Gehäuse (3) jeweils über eine Kombination aus übereinanderliegendem Gleitring (16, 17) und Elastomerring (22, 23) in Richtung der Lagermitte vorgespannt, so dass sowohl eine rückstellkraftfreie Verdrehung des Lagerinnenteils (2) um die Lagerachse (5) um den vollen Winkelbereich, als auch eine kardanische Auslenkung mit elastischem Widerstand möglich ist.
Abstract:
The invention relates to a bearing arrangement for a rotatable shaft (4) having an inner bearing part (6) for coupling to an end (16) of the shaft (4), an outer bearing part (8) for coupling to a mounting structure (20) and an axis of rotation (10), wherein at least one of the inner bearing part (6) and the outer bearing part (8) have at least in regions an elastic deformability at least partially perpendicular to the axis of rotation (10), and an arrangement comprising the bearing arrangement and a shaft (4) and a vibration exciter encompassing said arrangement.
Abstract:
A thrust bearing assembly includes an upper thrust bearing and a lower thrust bearing for use in an engine assembly of a vehicle and which, are preferably, identically configured. The upper and lower thrust bearings each include an arcuate bearing shell with a concave inner surface and a convex outer surface and each may be formed with a pair of axially spaced flanges extending radially outwardly of the bearing shells. The flanges may be formed as one piece with the bearing shell and the thickness of one of the flanges is greater than that of the other of the flanges. The thicker flanges are load bearing and preferably contoured, whereas the thinner flanges are not. The bearings are installed with the thick flange of each bearing matched radially opposite the thin flange of the companion bearing to minimize fatigue and failure normally attributed to repeated seating and unseating of the bearing assemblies having flanges of equal thickness caused by changing bending loads imparted by a shaft.
Abstract:
The invention relates to a sealed bearing which comprises a body (1) with a general cylindrical configuration for its assembly in the housing of a mold or support body (M), and has a cylindrical inner hole (3) for the assembly and balancing of the tight movement of a rotary shaft or core pin (N) provided with internal cooling. The body (1) has: an inner channel (11) for the assembly of a dual-effect rotary seal (7) activated by a first O-ring seal (8); an outer channel (12) for the assembly of a second O-ring seal (8) for the static sealing of the bearing in the housing of a mold or support part (M); and, at one of its ends, a head (5) with peripheral planes (6) and threaded holes (2) for its grip and extraction from the housing of the mold or support part (M).
