Abstract
A method for controlling a separation between rotational axes of a pair of meshing gears is disclosed. A parameter indicative of a transmission error through the gears is measured and the separation is controlled, aiming to minimise variations in the measured signal. This acts to reduce variations in transmission error and the related vibrations created in the drive system and in the surrounding components. A related drive system and aircraft landing gear are described.
Claims23
A drive system for an aircraft landing gear comprising:
- first and second gears for engagement to transfer a drive input to the system between the first and second gears;
- an actuator for adjusting a distance between rotational axes of the first and second gears;
- a sensor configured to detect at least one parameter indicative of a transmission error through the first and second gears;
- and
- a controller configured to control the actuator to adjust a distance between respective rotational axes of the gears, in response to the detected parameter, when the first and second gears are engaged to minimise the transmission error.
A method of controlling engagement of first and second gears in a drive system, comprising the steps of:
- detecting at least one parameter indicative of a transmission error through first and second gears of the drive system;
- and
- automatically adjusting a distance between respective rotational axes of the gears using an actuator in response to the detected parameter to minimise the transmission error.
