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, 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 turbine starter (10) for starting an engine (14), comprising a housing (30) having an interior surface defining an interior, at least one turbine member (38) rotatably mounted within the interior about a rotational axis, and having a plurality of circumferentially spaced blades (76), and a containment structure (78, 100, 200, 300) radially overlying and circumferentially surrounding at least a portion of the at least one turbine member (38). The containment structure has a plurality of walls (105, 114, 116, 205, 208, 308) defining a cell structure forming a plurality of cells (118, 210).
