Abstract
A testing stand for a helicopter transmission is arranged in a testing stand (20) capable of swiveling deflection around a rotor shaft (4) with one output side rotor shaft (4) and at least one drive side input shaft (6, 8). Actuators (28, 30) are provided around the rotor shaft axis (4) for swiveling deflection of the helicopter transmission (2) to equalize shifts on connection couplings (14, 16, 22) occurring under load. It is suggested that the helicopter transmission (2) be clampable in the testing stand (20) by connection elements (24, 26) elastic with respectable to swiveling deflection.
Claims7
A testing stand for a helicopter transmission (2) having an output side rotor shaft (4) and at least one drive-side input shaft (10, 12), the testing stand is connected to the transmission by shafts (6, 8) and connection couplings (14, 16, 22) with at least one testing stand side shaft connection, whereby the helicopter transmission (2) is capable of swiveling about the output side rotor shaft axis (4), and at least one actuator (28, 30) inhibits swiveling of the helicopter transmission (2) about the output side rotor shaft axis (4) in equalize shifting of the helicopter transmission (2) on the connection couplings (14, 16, 22) occurring under load, and the helicopter transmission (2) is clamped to the testing stand (20) by connection elements (24, 26) which are elastic with relation to swiveling deflection.
A testing stand for a helicopter transmission (2) with an output side rotor shaft (4) and at least one drive-side input shaft (10, 12);
- wherein at least one testing stand side connection connects the testing stand to the helicopter transmission (2), the testing stand side connection comprises at least one shaft (6, 8) and at least two connection couplings (14, 16, 22), the helicopter transmission (2) is clamped to the testing stand (20) by connection elements (24, 26) which are sufficiently elastic so that the helicopter transmission (2) is capable of swiveling about the output side rotor shaft axis (4) during testing, and at least one actuator (28, 30) inhibits the swiveling in order to equalize shifting of the helicopter transmission (2) on the connection couplings (14, 16, 22).
