Patent number: 10786883Abstract: An embodiment of a tool assembly includes a spring-loaded shaft assembly disposed along a first axis, a hub, and a roller disk. The hub is connected to a distal end of the spring-loaded shaft assembly. The hub has an upper hub portion adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis, and a lower hub portion extending along a second axis. The second axis forms an angle relative to the first axis. The roller disk is joined to the lower portion of the hub, and has a working surface about its perimeter. The roller disk is rotatable about the second axis parallel to the second portion of the hub. The working surface includes a profile along its width such that an effective radius of the roller disk varies along a width thereof.Type: GrantFiled: December 20, 2016Date of Patent: September 29, 2020Assignee: United Technologies CorporationInventors: Justin R. Hawkes, Joseph C. Rampone, Andrzej Ernest Kuczek, Tahany Ibrahim El-Wardany, Randy P. Salva, Patrick Louis Clavette, Thomas J. Garosshen

Patent number: 10179951Abstract: A method of applying a coating system to a substrate includes applying a first layer of a high hardness and high modulus of elasticity with an added metal to the substrate, applying a second layer of the high hardness and high modulus of elasticity in combination with the added metal to the first layer. A percent by volume of the added metal in the second layer is lower than the percent by volume of the added metal in the first layer. The method also includes applying two or more intermediate layers formed from an applied mixture of the high hardness, high modulus of elasticity material and a metal material between the first layer and the second layer.Type: GrantFiled: January 19, 2016Date of Patent: January 15, 2019Assignee: SIKORSKY AIRCRAFT CORPORATIONInventors: Aaron T.

Publication number: 20180171447Abstract: An embodiment of a tool assembly includes a hub connected to a distal end of a spring-loaded shaft assembly disposed along a first axis. An upper hub portion is adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis, and a lower hub portion extends along a second axis, forming a nonzero angle relative to the first axis. A roller disk is joined to the lower portion of the hub, and is rotatable about the second axis parallel to the second portion of the hub. A load cell is disposed along the first axis between a proximal end of the shaft and the roller disk, and is adapted to measure a downward force applied along the shaft assembly.Type: ApplicationFiled: December 20, 2016Publication date: June 21, 2018Inventors: Justin R.

Publication number: 20180171448Abstract: An embodiment of a tool assembly includes a robotic assembly, a tool mount, and a non-axisymmetric deep rolling tool. The robotic assembly includes a plurality of linear arms connected in series between a base end and a working end. Adjacent ones of the plurality of arms are connected via a corresponding plurality of multi-axis joints such that the working end is articulated by movement of one or more of the plurality of arms relative to one or more of the plurality of multi-axis joints. The tool mount is connected to one of the linear arms or one of the multi-axis joints at the working end of the robotic assembly. The non-axisymmetric deep rolling tool is connected to the tool mount, and includes a spring-loaded shaft assembly disposed along a first axis. A hub has an upper hub portion adjacent to the distal end of the spring-loaded shaft assembly aligned with the first axis, and a lower hub portion extending along a second axis, forming a nonzero angle relative to the first axis.Type: ApplicationFiled: December 20, 2016Publication date: June 21, 2018Inventors: Justin R.
