摘要： An axle assembly with a housing, a shaft received in the housing, a shaft bearing supporting the shaft for rotation relative to the housing about a shaft axis, a differential assembly, an annular band and a secondary retainer. The shaft bearing has an inner race, which is received on and directly engaged to the shaft, and an outer race that is received on and directly engaged to the axle housing. The differential assembly has an output member that is non-rotatably coupled to the shaft. The annular band is fixedly coupled to the shaft at a location along the axle shaft axis between the inner race and the output member. The secondary retainer is disposed along the axle shaft axis between the annular band and the output member and is configured to limit movement of the annular band along the axle shaft axis in a direction toward the output member.

摘要： An axle assembly having an input pinion with a pinion gear, which is received in an axle housing and rotatable about a first axis, and a pinion shaft. The pinion gear is meshed with a ring gear that is coupled to a differential assembly. A head bearing, which is disposed on a first axial end of the input pinion, supports the input pinion for rotation relative to the housing about the first axis. A tail bearing supports the input pinion for rotation relative to the housing about the first axis. The pinion gear is disposed axially between the tail bearing and the head bearing. A bearing groove is formed into the pinion shaft and the bearing elements are received into the bearing groove such that an inner bearing race of the tail bearing is unitarily and integrally formed with the pinion shaft.

摘要： A gas turbine engine, especially an industrial gas turbine engine for electrical power production, where a second compressor is used to supply a second compressed air at a higher pressure to a stage of stator vanes in the turbine section of the engine for cooling of the stage of stator vanes, and where the heated compressed air used to cool the stator vanes is then discharged into the combustor to be burned with a fuel and produce a hot gas stream that is passed through the turbine. an intercooler can be used with the second compressor to lower the temperature of the second compressed air used for cooling the stator vanes.

摘要： A powertrain with a disconnecting rear drive axle generally includes a prime mover including an output that rotates about a rotational axis. A transmission includes an output that rotates about a rotational axis. The rotational axes of the outputs are substantially parallel to a longitudinal axis of the powertrain. A front driveline is operable to direct rotary power from the prime mover to front vehicle wheels. A rear driveline includes a propeller shaft that provides rotary power to a first shaft member and a second shaft member through a pinion and a ring gear. The first shaft member and the second shaft are operable to connect to rear vehicle wheels. A power switching mechanism has an engaged condition and a disengaged condition. The power switching mechanism is operable to direct the rotary power from the transmission to the rear driveline in the engaged condition. A torque transfer device has an engaged condition and a disengaged condition. The power switching mechanism and the torque transfer device in the disengaged condition are operable to only transmit rotary power to the first vehicle wheels. The torque transfer device in the disengaged condition prevents the first shaft member and the second shaft member from back-driving the ring gear and the pinion of the rear driveline. The power switching mechanism in the disengaged condition prevents the transmission from driving the propeller shaft.
