The split shaft further includes a distal shaft section having a first distal shaft end and a second distal shaft end. The first distal shaft end is configured to couple to the second machine arrangement. The second distal shaft end is configured to engage with the second proximal shaft end to convey the drive power from the first machine arrangement to the second machine arrangement. The second proximal shaft end includes a first indicator, and the second distal shaft end includes a second indicator. Alignment of the first indicator and the second indicator conveys timing for the drive power.

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 being axially mounted between a lateral face of the first ring and the sleeve. The first ring having at least one anti-rotation feature cooperating with at least one complementary anti-rotation feature formed on the impulse ring so as to prevent angular movement of the impulse ring relative to the first ring.

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.

An angle adjustable bicycle saddle contains a seat post, a cushion, and a locking unit. The seat post includes an inwardly curved groove having multiple protrusions, and the seat post includes multiple troughs. The cushion includes a body and a cap. The body has a curved holder, an arcuate abutting projection, multiple engagement portions, and multiple through holes for corresponding to the multiple troughs. The cap is covered on the curved holder of the body so that the curved holder has a hollow portion. The locking unit includes multiple fixing elements and multiple stepped nuts. A respective fixing element is inserted through a respective trough and a respective through hole. A first end of a respective fixing element is adjustably received in a respective trough, and a second end of the respective fixing element is accommodated in the hollow portion of the curved holder.

Vehicle input shafts are disclosed. The vehicle input shafts include a bearing boss, a spline portion, a cylindrical shaft body portion and a drive end. The spline portion includes spline teeth and spline grooves that do not exit directly onto the shaft body. Instead, the spline grooves include blend out fillets that interrupt the spline grooves by providing additional material near the shaft body. The bearing boss includes an increased diameter at a central point along its axial length and decreased diameters at its first and second boss ends.

An engine includes a crankshaft and a timing gear to be attached to the crankshaft so as to rotate integrally with the crankshaft. A fitting projection is provided on either one of the crankshaft and the timing gear, and a fitting recess to be fitted with the fitting projection, and erroneous-assembling prevention ribs to sandwich the fitting recess in a circumferential direction are provided on the other one of the crankshaft and the timing gear.

Bearing assemblies and methods of using bearings are provided in the present disclosure. In one embodiment, a bearing ring is provided having a plurality of carrier components removably coupled therewith. Each carrier component may carry one or more bearing elements. Upon wearing of the bearing elements beyond a desired amount, the carrier components may be removed from the bearing ring and installed in a different bearing ring to place the mearing elements at their original bearing surface radius. In another embodiment, individual bearing elements may be radially adjustable relative to the bearing ring to define and redefine the radius of a radial bearing surface.

A washer assembly and a hydrodynamic torque converter comprising the washer assembly is provided. The washer assembly comprises a washer and a plate; the washer is annular and comprises a washer body and two or more positioning clamps protruding radially inward from an inner periphery of the washer body, at least one side of the positioning clamp in a circumferential direction having a positioning protrusion protruding; the plate is annular, an inner periphery portion of the plate being provided with two or more positioning notches; an edge of at least one side of the positioning notch in the circumferential direction being provided with a positioning groove; and the washer is mounted to one end face of the plate. The washer assembly saves the internal space of the torque converter and saves the material cost of the washer.

A bearing assembly and method of installation. A ball bearing includes an outer race, an inner race, and a separate L-shaped sleeve. In one embodiment, the sleeve is comprised of an axially extending body and a radially extending flange. The axially extending body is configured to be located between an inner diameter of the inner race and a transmission shaft, and the radially extending flange is configured to be located between an inner side surface of the inner race and the transmission shaft. The L-shaped sleeve with splines makes it feasible to sequentially press fit both the inner race and the outer race of the ball bearing. The spline in the axially extending body of the sleeve can slip-fit with the transmission shaft, allowing for ease of assembly, and enabling a press-fit connection between the ball bearing outer race and housing. This arrangement can help reduce wear, particularly to the housing, and better control axial movement of the bearing assembly due to gear thrust load direction change during operation.

An assembly and a method for manufacturing an assembly for transmitting torque to an aircraft actuator. The assembly and method include a torque tube having a longitudinal axis and an end fitting. The ending fitting includes a connector portion and an engagement portion that is inserted into the torque tube. The engagement portion includes a first end adjacent the connector portion, a second end opposite the first end, and a coupling region between the first and second end that includes an outer coupling surface having an outer diameter and a continuous groove formed thereon. The continuous groove includes two axial grooves that extend along the outer coupling surface along the longitudinal axis and a first parallel groove that extends circumferentially about the longitudinal axis along the outer coupling surface that joins the two axial grooves.
