A motor is to be mounted on a vehicle as a drive source. The motor includes a motor shaft extending in an axial direction, a drive gear provided on the motor shaft, a gear shaft extending in the axial direction, a driven gear provided on the gear shaft and coupled to the drive gear, a rotating member, an inner bearing that supports the gear shaft, and an outer bearing that supports the gear shaft. The rotating member is provided on the gear shaft and is configured to be coupled to a power transmission member that transmits power to a wheel of the vehicle. The rotating member is located between the inner bearing and the outer bearing in the axial direction.

Alloy materials and three-dimensional (3-D) printed alloys are disclosed. An alloy in accordance with an aspect of the present disclosure comprises aluminum, magnesium, and silicon wherein a composition of the alloy comprises from at least 5 percent (%) by weight to 20% by weight of silicon and from at least 7% by weight to 10% by weight of magnesium.

An axle assembly that includes a differential carrier, a bearing cap, and a lubricant reservoir. The differential carrier has a bearing support. The bearing cap is disposed on the bearing support. The lubricant reservoir is mounted on the bearing cap and is configured to capture lubricant that is splashed by the differential assembly.

A modular gearbox assembly for a wind turbine having improved up-tower serviceability includes a low-speed gear stage module, a separate, intermediate-speed gear stage module adjacent to the low-speed gear stage module, and a separate high-speed gear stage module adjacent to the intermediate-speed gear stage module. The gearbox assembly also includes a first flange removably connecting the intermediate and high-speed gear stage modules and a second flange removably connecting the intermediate and low-speed gear stage modules. Thus, the low-speed gear stage module converts a low-speed, high torque input from a rotor shaft of the wind turbine to a high-speed, low torque output for a generator of the wind turbine via the intermediate and high-speed gear stage modules. In addition, the first and second flanges allow for easy disassembly of the gear stage modules such that the various stages can be easily repaired, replaced, and/or inspected.
