    摘要： A rotary machine includes rotating shaft supported with respect to an end wall of a housing. The rotary machine includes a bearing that is attached to the rotating shaft and rotatably supports the rotating shaft to the housing, a cylindrical holding portion that is provided in the end wall of the housing and extends in an axial direction of the rotating shaft, and a cylindrical bearing sleeve that is fixed to the holding portion and surrounds the bearing. The bearing sleeve includes a surrounding portion that surrounds the bearing and a protruding portion that protrudes from the surrounding portion toward the end wall. The protruding portion and the holding portion overlap each other in a radial direction of the rotating shaft, and the bearing sleeve is fixed to the end wall by fitting the protruding portion into the holding portion.

    摘要： A flange for centering an impeller on a motor shaft includes a central bore for receiving a motor shaft, an impeller facing end and a motor bearing facing end formed opposite the impeller facing end, wherein the impeller facing end includes at least one impeller engaging element configured to couple with a flange facing side of the impeller, wherein the flange facing side of the impeller includes at least one flange engaging element complementary to the at least one impeller engaging element of the flange. An assembly including the motor shaft an impeller is disclosed, as well as centering elements for use in repeatably mounting the assembly to an impeller. Methods of determining optimal balance are disclosed.

    摘要： A turbocharger including, a turbine wheel (10), a shaft (111) attached to the turbine wheel (10), and a compressor wheel (132) disposed on the shaft (111) opposite the turbine wheel (10). The compressor wheel (132) includes a back wall (134) and an axial bore (137) and a pilot washer (150) is located adjacent the compressor wheel back wall (134). The pilot washer (150) has an inner diameter (162) and an outer diameter (160), and includes a conical pilot ring (154) that extends into the axial bore (137) of the compressor wheel (132). The pilot washer (150) includes a slit (164) extending from the inner diameter (162) to the outer diameter (160). A nut (113) is threaded to the shaft (111) and is operative to provide an axial clamping force on the compressor wheel (132), thereby causing the pilot washer (150) to contract onto the shaft (111) as the pilot ring (154) extends into the bore (137).
