摘要： A hub-bearing assembly includes a stationary radially outer ring, a flanged hub extending into an interior of the radially outer ring and configured to rotate relative to the radially outer ring, and a radially inner ring mounted on the flanged hub and axially abutting a portion of the flanged hub. A toothed sleeve is mounted to the hub axially inward of and adjacent to the radially inner ring and is rotationally fixed relative to the flanged hub. An auxiliary ring is mounted on the flanged hub in contact with the toothed sleeve. The flanged hub includes an axially inner rolled edge in contact with the auxiliary ring and configured to maintain a preload on the radially inner ring, and the auxiliary ring is configured to accommodate deformations induced by the formation of the rolled edge.

摘要： A hub bearing unit includes a hub, a bearing unit having an internal seat, an outer ring connected to the internal seat, a inner ring, and a sealing device between the inner and outer rings. The sealing device includes a first shield mounted to the inner ring, a second shield mounted to the outer ring, and an elastomeric seal body on the second metallic shield. The hub has a radially inwardly extending shoulder delimiting the internal seat and located axially outward of the first shield, and a path extends from outside the hub to the gap. The path includes a first portion defined by an axially inwardly facing surface of the shoulder and an axially outwardly facing surface of the shield and a second path portion between a radially outer edge of the shield and a radially inwardly facing cylindrical surface of the elastomeric seal body.

摘要： A sealing device for a sleeve of washing machines, comprising a first, stationary, annular screen, and a second, rotatable, annular screen. The first annular screen includes a first cylindrical mounting portion and a first flange portion; and the second annular screen includes a second cylindrical mounting portion and a second flange portion. The sealing device is characterized in that both the first and the second annular screens include the same number of non-contacting sealing lips, which are similar to each other and contained axially between the first and second flange portions, in radially alternating positions axially arranged one above the other, so as to define a sealing labyrinth (L). The first and second annular screens define between them a discharge chamber (C1) and an obstruction chamber (C2) which are arranged along the sealing labyrinth (L), substantially at opposite ends of the said sealing labyrinth (L).

摘要： A method for determining distance between a measuring unit and a point of a first machine when performing a process of aligning the shafts of the first machine and a second machine includes a step of securing the measuring unit to one of the shafts. The method further includes the steps of determining the length of a segment between the measuring unit and a reference surface of the first machine and calculating the distance between the measuring unit and the point of the first machine from the determined length of the segment and a predetermined dimension between the reference surface and the point of the first machine.

摘要： A liner configured to be mounted on a radially inner or outer surface of a bearing ring has a generally cylindrical base having first and second axial ends and at least one groove and at least one side wall extending radially from the first or second axial end. The liner is non-metallic and has a base portion covering the inner or outer surface of the bearing ring and a plurality of side wall sections extending radially over at least a portion of at least one axial side of the ring. The base is formed from a plurality of circumferentially adjacent axially extending subsections, each pair of which is connected by a least one hinge having a radial thickness less than a radial thickness of the base portion. Also a bearing assembly that includes a bearing housing and the bearing ring with the liner contacting the bearing housing.

摘要： A bearing device includes a first ring and a second ring mounted for relative rotation and an insulating sleeve including a socket and an electrically insulating liner. The socket has at least one recess, and the liner has at least one protrusion extending into each of the at least one recess. The liner is overmolded on the second ring and on the socket such to connect the second ring to the socket.

摘要： A grounding brush assembly includes a grounding brush having a support and a plurality of conductive fibers fitted inside the support. A brush fitting plate is connected with the support of the brush and includes a plurality of retention tongues configured to retain the support of the brush, a radial portion, an annular flange extending from the radial portion and spaced radially outwardly from the retention tongues. The fitting plate also includes a plurality of through-openings, which each extend through the radial portion and through the flange, and at least one local deformation formed on the flange of the fitting plate and extending radially inwardly.

摘要： A seal assembly is for sealing between an outer member and an inner member, one of which is rotatable about a central axis. An outer annular case is coupled with the outer member and an inner annular case is disposed within and spaced radially inwardly from the outer case. An annular sealing member is disposed within and coupled with the inner case, the sealing member having a centerline coaxial with the central axis and a sealing lip or lips engaged with the inner member. An annular elastomeric coupler has a first axial end attached to the outer case and a second axial end attached to the inner case. The elastomeric coupler is radially deflectable such that the outer case or inner case is radially displaceable relative to the other one of the two cases while the centerline of the sealing member remains coaxial with the central axis.

摘要： A wave spring having an axially resilient spring section including at least one one-layer wave-shaped spring configured to provide a spring force in an axial direction of the wave spring, and a radially resilient spring section configured to provide a spring force in a radial direction. The wave spring may be made from a continuous flat wire that forms both the axially resilient spring section and the radially resilient spring section, the flat wire being rotated 90° at a transition from the axial spring section to the radial spring section.
