Automatic braking engagement device for e.g. rotor of helicopter, has runners, where centrifugal force exerted on runners induces thrust load less/greater than another thrust load to ensure braking of shaft/axial displacement of trolley |
摘要 |
<p>The device has a set of runners (22, 23) uniformly distributed around a rotary shaft (1). Centrifugal force exerted on the runners induces a thrust load on a braking trolley (25) according to reverse direction/opposite direction of axial direction, where the load is less/greater than another thrust load exerted by an elastic return unit (36) so as to ensure braking of the shaft/to ensure translational axial displacement of the trolley when the runners are arranged below/above predetermined rotation speed of the shaft.</p> |
