An assembly includes a rotating shaft supported with respect to a stationary housing by at least one active magnetic bearing presenting a mean radial air gap and at least one auxiliary bearing having first and second coaxially arranged annular surfaces is provided. One of the first and second coaxially arranged annular surfaces defines a clearance (E2) with one of the stationary housing and the rotating shaft, the clearance (E2) being less than the mean radial air gap and the other of the first and second coaxially arranged annular surfaces being integral with the other one of the stationary housing and the rotating shaft. The auxiliary bearing provides a first ball bearing and a second ball bearing having a misalignment with respect to each other in order to increase the starting torque.

A bearing system that accepts a journal of a roll includes a housing defining a cavity and having a forward wall that defines an opening into the cavity, the opening configured to accept the journal through the opening and into the cavity. A sleeve is positioned within the cavity of the housing, the sleeve configured to surround the end of the journal. A first seal is positioned within the cavity of the housing adjacent to the forward wall of the housing, the first seal having an engagement surface. A second seal is positioned within the cavity of the housing and operably connected to the sleeve, the second seal having an engagement surface in contact with the engagement surface of the first seal.

A circumferential lubricant scoop for providing lubricant to a bearing assembly. The scoop is disposed circumferentially about and rotates with a rotor shaft. The scoop comprises a plurality of lubricant capturing vanes shaped to capture and retain lubricant in a cavity behind a lower lip of the vane. This cavity is in fluid communication with channels leading to fluid pathways of an inner race of the bearing assembly. Fluid is moved through the channels and fluid pathways due to the rotational force imparted by the rotating rotor shaft.

An ice maker includes a casing that defines a chamber. The casing extends between a top portion and a bottom portion. An extruder die is mounted to the casing at the top portion of the casing. An auger is disposed within the chamber of the casing. A radial sleeve bearing engages the auger at the bottom portion of the casing. A radial and thrust bearing engages the auger at the extruder die. A related refrigerator appliance is also provided.

The invention relates to a self-propelled harvesting machine comprising:—a removable harvesting unit (6) which can be mounted at the front in the direction of travel (F);—a processing unit in the interior; and—a harvested material conveyor channel (5) connecting said harvesting unit, when mounted, to the processing unit. According to the invention, the self-propelled harvesting machine is characterised in that a receiving space which at least partially receives said conveyor channel when in the harvesting mode can have its width adjusted transversely to the direction of travel.

A bearing assembly includes a bearing, in particular a non-locating bearing, for supporting a shaft within a housing. The bearing provides an inner ring and an outer ring. A radially outer surface of the outer ring and/or a radially outer surface of the shaft and/or a radially inner surface of the inner ring and/or a radially inner surface of the housing has a protection layer. The protection layer is a thermally expanding or shrinking layer being thermally heated and expanded to or shrunk on the respective radially inner surface and/or radially outer surface. Further, a method for manufacturing a bearing ring for such a bearing assembly is disclosed.

An aircraft rotor system includes a rotating pitch change shaft which rotates about an axis, a translating element disposed within the rotating pitch change shaft and movable along the axis and a pitch change bearing assembly which transfers movement of the translating element to the pitch change shaft. The pitch change bearing assembly includes a primary bearing and a secondary bearing coupled to the rotating pitch change shaft via the translating element when the primary bearing is in a first mode. A thrust shoulder is coupled to the translating element. The thrust shoulder is movable into engagement with the secondary bearing in response to failure of the primary bearing such that in a second mode, movement of the translating element is primarily transferred to the pitch change shaft via the secondary bearing.

A rotary joint which, in order to limit the mutual rotation of the outer bearing ring (2) with respect to the inner bearing ring (2), is provided with a raceway (11), which is limited by one or two stops (14) and in which a projection connected to the outer bearing ring engages. In order to ensure that a rotation greater than 360° is possible, the raceway is of helical design.

A pulley device comprising a rolling bearing including an inner ring defining a central bore, and outer ring and rolling elements mounted between the inner ring and the outer ring, a pulley secured in rotation with the outer ring and provided with a feature for engaging with a transmission member. The pulley additionally includes a screw comprising a head and a shank housed in the central bore of the inner ring, the screw being configured to fix the pulley device to a motor support. The pulley device also comprises a first sleeve arranged between the inner ring and the screw, on the side of the motor support. The first sleeve includes an inner surface that has a frustoconical portion having an increasing diameter toward the head of the screw.
