Drive system for a high lift system of an aircraft and method for detecting a misalignment between a transmission shaft and an opening in a drive system for a high lift system of an aircraft

摘要

An arresting apparatus for arresting a rotational motion of two components relative to each other is provided. The arresting apparatus includes a first arresting means having a longitudinal axis and at least one first engaging element, and a second arresting means having an opening and at least one second engaging element. In a first mode of operation, the first arresting means extends through a first section of the opening of the second arresting means such that it is freely rotatable and the first engaging element and the second engaging element are distanced from each other. In a second mode of operation, the first arresting means is misaligned and extends through a second section of the opening of the second arresting means such that the first engaging element and the second engaging element engage and arrest the first arresting means relative to the second arresting means.

主权项

1. A drive system for a high lift system of an aircraft, comprising:
an opening, a transmission shaft being rotatable about an axis and extending through the opening with a radial play, at least one first engaging element being located at the transmission shaft and protruding radially outward into the opening, at least one second engaging element being located at the opening and protruding radially inward into the opening, wherein the at least one first engaging element and the at least one second engaging element engage each other and in case a relative radial displacement between the transmission shaft and the opening exceed the radial play, the engagement prevents further rotation of the transmission shaft.
