摘要： A mounting system for a planetary gear train (30) in a gas turbine engine (10) comprises a support strut (56), a deflection flange (74) and a deflection limiter (52). The support strut extends between a stationary engine case (42) and a rotating engine shaft (22) that provides input to the planetary gear train in the gas turbine engine. The deflection flange extends from a rotating output component (68) of the planetary gear train. The deflection limiter is connected to the support strut and engages the deflection flange when the gear train becomes radially displaced.

摘要： A fan drive gear system for a gas turbine engine includes a torque frame (44) and a journal bearing (50). The torque frame has an arm (60) that extends therefrom, the journal bearing is mounted on the arm. When the fan drive gear system is in an unloaded condition an outer circumferential surface of the journal bearing is disposed at an angle so that it is non-parallel with respect to an axis (R) of the arm. When the fan drive gear system is in a loaded condition the outer circumferential surface is disposed substantially parallel to the axis of the arm. In another aspect, the journal bearing includes a main body, a first wing, and a second wing. The first and second wings extend from the main body and are asymmetric with respect to one another.

摘要： The invention relates to a method for setting the tooth face position of a gear wheel (2), which is positively connected to a double helical pinion shaft (1). A hydraulic press fit (4, 4a) is formed between the gear wheel (2) and pinion shaft (1) in order to be able to eliminate a non-positive connection of the gear wheel (2) shrink-fitted onto the pinion shaft (1), shrink-fitting the gear wheel (2) in order to set the gear wheel position. The setting is carried out by determining a tooth face apex point (A) of the double helix of the pinion shaft (1). A radial plane (E) at a predetermined axial offset (AV) from the tooth face apex point (A) and a radial offset (RV) with respect to the tooth face apex point (A) are defined. The intersecting point (S) of a tooth face (11) of the gear wheel (2) must be located in the predetermined radial offset (RV) in the radial plane (E). Such a pinion shaft (1) is used particularly in a power-splitting spur gearbox (12), wherein an input shaft is multiply engaged with several pinion shafts (1) via a double helix, the gear wheels (2) of the pinion shafts (1) in turn being multiply engaged with a common output shaft (15).

The planetary carrier (11) supports the planetary shafts (13) between the angular base plate (17) and the annular back plate (19) and determines a relative position between planetary gears (7). The annular base plate (17) is integrally formed with one end of the planetary shaft (13) to support the one end. The annular back plate (19) supports the other end of the planetary shaft (13). At least one of the planetary shaft (13) and the planetary carrier (11) has lower stiffness in its part adjacent to the one end of the planetary shaft (13) than stiffness of its part adjacent to the other end thereof.

摘要： A gear apparatus has at least two meshed gears (3, 5). One gear (5) is mounted on a conical main shaft (8) such as to be movable in the axial direction. The gear apparatus is further provided with a means for bearing any thrust generated in relation to the gear (5). In the case where a plurality of gears (5) are provided, the space (S) between the surface of the conical shaft (8) and the inner peripheral surface of a bearing (17) for each gear (5) is changed in accordance with the position of the gear (5) in the axial direction of the conical shaft (8) by the action of a device for balancing thrusts generated in relation to the gears (5), whereby the offset between the axis of the conical shaft (8) and the center of rotation of each gear (5) is varied, thereby making uniform the loads respectively imposed on the gears (5).
