A bearing cover assembly configured to assemble to a bearing housing in which a rolling element bearing is accommodated. The bearing housing assembly includes an end cap with a sleeve portion that mates to an interior conical surface of the bearing housing with a complementary outer bevel formed on the sleeve portion.

A steering shaft assembly (10) for a motor vehicle is described, comprising a first shaft (20) and a second shaft (22), both of which are rotatable about a central axis (24). The second shaft (22) is a hollow shaft and a portion of the first shaft (20) is received so as to be axially displaceable inside the second shaft (22). The first shaft (20) and the second shaft (22) are also coupled in a torque-transmitting manner via two rotary coupling mechanisms (26, 28) separate from each other.

An elastic articulation comprising a first sleeve and a second sleeve is provided. The first sleeve and the second sleeve each include a respective outer armature, a respective inner armature, and a respective elastic body between their respective outer and inner armatures. The elastic articulation also comprises a ring longitudinally connecting the first sleeve and the second sleeve. The ring forms a radial stop between the inner armature and the outer armature of the first sleeve, and between the inner armature and the outer armature of the second sleeve. The elastic articulation improves damping control in different directions.

A system for the axial retention of a holding ring for a bearing for guiding in rotation a rotary shaft of a turbomachine is disclosed. The system includes an annular bearing support and a bearing holding ring that is borne by the annular bearing support. The bearing holder ring includes an upstream ring configured to be brought into contact with the bearing support and a downstream ring that is elastically deformable. The bearing support has a first axial retention element, and the bearing holding ring has a second axial retention element. The first and second axial retention elements are configured to cooperate with one another to axially retain the bearing holding ring in the event of damage to the downstream ring.

The sensor bearing unit provides a bearing having an inner ring and an outer ring centered on an axis, the inner ring mounted on a shaft, and an impulse ring provided with a target holder and with a target mounted on the target holder, the target holder being secured to the inner ring. The target holder includes anti-rotation features adapted to cooperate with complementary anti-rotation features of the shaft so as to prevent angular movement of the impulse ring relative to the shaft by abutment in circumferential direction.

A length-adjustable connecting rod is disclosed having a longitudinal axis comprising a connecting-rod shank provided with at least one internal thread, at least one connecting element comprising an external thread cooperating with the internal thread of the connecting-rod shank, the screwing or unscrewing of the connecting-rod shank with respect to the connecting element allowing the length of the connecting rod to be adjusted, and at least one resisting torque device between the connecting-rod shank and the connecting element, the resisting torque device comprising at least one pressing element and a bearing element, the pressing element exerting a force on the bearing element that opposes a resistance to the rotational movement of the connecting-rod shank with respect to said connecting element. The bearing element is integral with the connecting element and the pressing element is integral with the connecting-rod shank.

A sensor bearing unit includes a bearing having a first ring and a second ring, and an impulse ring provided with a target holder, with a target mounted on the target holder, and with a sleeve secured to the first ring. The target holder having a mounting portion secured to the first ring of the bearing. The target holder has at least anti-rotation feature axially spaced apart from a free end of the mounting portion and cooperating with a complementary anti-rotation feature of the first ring so as to prevent angular movement of the impulse ring relative to the first ring. The anti-rotation feature of the target holder extends into the complementary anti-rotation feature of the first ring.

A tie rod including a first tie rod part and a second tie rod part of plastic material, and a joint providing a length-adjustable connection between the first and second tie rod parts is provided. The joint includes a first and a second series of ribs made on the first and second tie rod parts, respectively. The first series of ribs is capable of engaging with the second series of ribs to define a relative longitudinal position of the first and second tie rod parts. The joint further includes a clip hinged to the first tie rod part and carrying the first series of ribs, the clip being foldable to snap onto the first tie rod part to lock an end of the second tie rod part within a seat of the first tie rod part.

An apparatus and method for assembling a split sleeve onto a shaft. The split sleeve apparatus provides a first and second arcuate portion with each having a partial cylindrical configuration. The first and second arcuate portions have at least one finger extending circumferentially outward from their opposing ends. The at least one finger from each of the first and second arcuate portions complementarily engage one another to form a continuous cylinder. At least one aperture extends longitudinally through the at least one finger of the first and second arcuate portions. A dowel rod extends through the at least one aperture for connecting the first and second arcuate portions to form the cylinder. The first and second arcuate portions are fabricated from a material having heat expansion characteristics that allow the material to expand when heated during assembly and to contract when cooled creating an interference fit with the shaft.

A bearing system includes a bearing housing and a foil bearing assembly. The bearing housing includes a sleeve that defines a cylindrical bore and includes at least one bearing assembly locking feature, and a mounting structure. The foil bearing assembly includes an outer foil assembly, an inner foil assembly, and a bump foil assembly positioned between the outer foil assembly and the inner foil assembly. The outer foil assembly includes at least one outer foil pad that extends circumferentially from a first end including a bearing retention feature to a second end. The bearing retention feature is cooperatively engaged with the at least one bearing assembly locking feature. The inner foil assembly includes a plurality of circumferentially-spaced inner foil pads. Each inner foil pad extends circumferentially from a tab to a free end. At least one inner foil pad is welded to the outer foil assembly along the tab.
