A drive axle shaft and method for making the same are provided. A tubular blank is inserted in a first die including an orifice. The tubular blank is extruded through the orifice to form an elongate tubular body with a longitudinal axis. A first longitudinal end of the tubular body is heated. The tubular body is inserted into a bore in a support apparatus. The support apparatus defines a second die at one end surrounding the bore, and the first longitudinal end of the tubular body projects outwardly from the bore. A third die comprises a mandrel configured to be received within the tubular body. A wheel flange is formed by moving at least one of the support apparatus and the third die toward the other of the support apparatus and the third die to deform the first longitudinal end of the tubular body between the second and third dies.

Systems, methods, and apparatus are disclosed for transferring a rotational force. For example, apparatus may include a shaft member that may include a first end configured to receive the rotational force from a first mechanical component. The shaft member may be configured to receive a torque in response to receiving the rotational force at the first end. The shaft member may also include a second end that may be configured to provide the rotational force to a second mechanical component. The shaft member may further include an outer surface and an inner surface that defines an internal volume of the shaft member. The apparatus may also include a support member that may be configured to transmit the torque. The support member may include a plurality of lobes that have a spiraled geometry. The support member may be coupled to the shaft member.

An in-wheel assembly is provided, and the in-wheel assembly includes an in-wheel actuator and a wheel. The in-wheel actuator includes a driving motor; a decelerator which is disposed inside the driving motor and configured to reduce a rotational speed of the driving motor; and a hollow shaft which is disposed inside the driving motor and configured to transfer a rotational force of the driving motor to the decelerator, which is accommodated in a hollow of the hollow shaft, and circulates fluid inside of the driving motor with respect to a surface of the decelerator when driven to rotate by the driving motor. The wheel accommodates the in-wheel actuator and receives a rotational speed reduced by the decelerator to rotate.

A bearing seal assembly of a rotary machine includes and inner shaft and an outer shaft. The outer shaft is disposed concentrically around and radially outward from the inner shaft. The space between the inner and outer shafts forms an annulus void. The inner shaft includes an oil inlet port through which lubricating oil enters the annulus void. A grooved structure is located on an inner surface of the outer shaft, and the grooved structure is configured to retain oil upon shutdown of the rotary machine. A bearing is located outside of the outer shaft. An oil outlet port is disposed in the outer shaft and is connected to the grooved structure for supplying lubricating oil to the bearing.

A stabilizer link and a manufacturing method therefor which can ensure strength required in wing plates and a center supporting plate and in a support bar, and which can ensure strength required in ribs. The support bar has a top wing plate, a bottom wing plate, a center supporting plate, and a plurality of ribs. In the wing plates and the center supporting plate, reinforcing fiber is orientated to a longitudinal direction of the support bar. In the rib, the reinforcing fiber is orientated to a perpendicular direction of the support bar. A longitudinal orientation ratio D1 at a longitudinal center portion of the top wing plate and the bottom wing plate, a perpendicular orientation ratio D2 at a perpendicular center portion of the ribs, and a perpendicular orientation ratio D3 at a perpendicular end portion of the ribs satisfy Equation 1. D1>D2>D3 Equation 1

A shaft for a bearing lubrication assembly includes an outer surface and a reservoir disposed within the shaft. A first seal groove is formed on the outer surface and extends a full circumference of the outer surface. A second seal groove is also formed on the outer surface and extends the full circumference of the outer surface. A radial port extends from the reservoir to the outer surface, the radial port intersecting the outer surface between the first seal groove and the second seal groove. A plurality of chambers are formed in the shaft and disposed axially between the first seal groove and the second seal groove. The plurality of chambers are open to the outer surface with each chamber having a closed bottom disposed radially inward from the outer surface. Each chamber is also circumferentially spaced from one another.
