A gear arrangement for transmitting torque through an angle and through a plurality of power extraction paths. The arrangement includes a driving shaft (20), a floating spur gear pinion (22) concentrically mounted on the drive shaft, a pair of concentric and opposed face gears (32, 34) that are in meshing engagement with the pinion (22), a primary driven shaft (42) mounted to one of the face gears (32) and at least one non-floating spur gear (60) also in meshing engagement with both face gears (32, 34). The driving shaft is located by a bearing or a flexible coupling (28) at the shaft end remote from the gear box to allow the pinion (22) to float freely. Useful power may be extracted from both face gears (32, 34) and the non-floating spur gear (60) as well as additional spur gears (92) that are placed in meshing engagement with the face gears.
Configuration d'engrenages pour la transmission d'un couple selon un angle, . plusieurs prises de force. Cette configuration comporte un arbre menant (20), un pignon d'engrenage . denture droite flottant (22) mont' concentrique sur l'arbre de tranmission, un jeu de deux engrenages concentriques sur face plane oppos'e (32, 34) qui engrSnent sur le pignon (22), un arbre men' primaire (42) mont' sur l'un des engrenages sur face plane (32) et au moins un engrenage . denture droite non flottant (60) qui engrSne sur les deux engrenages sur face plane (32, 34). L'arbre menant est positionn' par un palier ou un accouplement souple (28) . l'extr'mit' de l'arbre oppos' . la boOte d'engrenage, pour permettre au pignon (22) de flotter librement. La force utile peut ¬tre extraite . la fois des engrenages sur face plane (32, 34) et de l'engrenage . denture droite non flottant (60) ainsi que des autres engrenages . denture droite (92) qui engrSnent sur les engrenages sur face plane.
