摘要： An air turbine starter (10, 210, 410, 610, 810) includes a housing (30) having a primary inlet (32) and primary outlet (34) to define a primary air flow path (36) from the primary inlet (32) to the primary outlet (34). A turbine (54) that includes a rotor (58) with a plurality of circumferentially spaced blades (60) extends into the primary air flow path (36) and is operably coupled with a drive shaft (66). A gear box (72) that includes a gear train (68) couples to the drive shaft (66). A first bearing assembly (74) is located between the drive shaft (66) and the housing (30). A second bearing assembly (114, 116) rotatably supports a carrier (82, 282, 482, 682) coupled to the gear train. A third bearing assembly (102, 302) is located between the carrier (82, 282, 482, 682) and the housing (30).

摘要： An air turbine starter (10) for starting an engine (14), comprising a housing (30) defining an inlet (32), an outlet (34), and a flow path (36) extending between the inlet (32) and the outlet (34) for communicating a flow of gas there through. A turbine member (38) is journaled within the housing (30) and disposed within the flow path (36) for rotatably extracting mechanical power from the flow of gas and a gear train (40) is drivingly coupled with the turbine member (38). A drive shaft (64) is operably coupled with the gear train (40), and a decoupler (70) is selectively coupled to the drive shaft (64) for decoupling the air turbine starter (10) from the engine (14).

摘要： An air turbine starter (10, 210, 410, 610) that includes a housing (30). The housing (30) can circumscribe a turbine (54) coupled that is coupled to a gear train (68) in a gear box (72) via a drive shaft (66). The gear train (68) can couple to an output shaft (80, 680) via at least a carrier (82, 282, 482, 682). The air turbine starter (10, 210, 410, 610) can include at least a first bearing assembly (74) and a second bearing assembly (76, 476, 676) to rotatably support one or more of the drive shaft (66), the carrier (82, 282, 482, 682), or the output shaft (80, 680).

摘要： An air starter (10, 110, 210) for starting a turbine engine (14) that includes a housing (30, 130, 230), a turbine member (42, 142, 242), a drive shaft (50, 150, 250), and at least one bearing assembly (64, 66, 164, 166, 264, 266). The housing (30, 130, 230) can define an interior (31, 131, 231) where the turbine (42, 142, 242) couples to the drive shaft (50, 150, 250) that is rotatably supported by the least one bearing assembly (64, 66, 164, 166, 264, 266). A lubricant passageway (82, 182, 282) can provide lubrication to the at least one bearing assembly (64, 66, 164, 166, 264, 266).
