Patent number: 11649039Abstract: Aerostructure actuator systems include first and second shaft portions having respective first and second mandrels and a clutch assembly arranged within the first mandrel and connecting the shaft portions. The clutch assembly includes a post with a post extension fixedly connected to the second mandrel. A first bearing is installed on the post extension to frictionally engage with a portion of the post. A second bearing is installed on the post. A spacer is arranged between the bearings and is fixedly attach to the first mandrel. A load setting nut is configured to engage with the post extension and apply a compressive force to the bearings and spacer against the post. The compressive force defines a coupling limit between the shaft portions. The clutch assembly is configured to rotationally decouple the shaft portions from each other if a relative rotational speed between the shaft portions exceeds the coupling limit.Type: GrantFiled: January 26, 2022Date of Patent: May 16, 2023Assignee: Hamilton Sundstrand CorporationInventors: Darrell E.
