Patent number: 10968744Abstract: A retaining collar is disclosed for a bayonet mount comprising a rotor disc having a male mounting member defining a pair of apertures and an auxiliary annular wheel defining a plurality of mounting slots. The retaining collar comprises a ring-shaped body and a pair of retention pins. The ring-shaped body has a pair of circumferential end portions separated by a circumferential gap, and an arcuate radial outer surface extending circumferentially between the end portions. The body is dimensioned so that the radial outer surface frictionally engages a radial inner surface of a cylindrical male mounting member in the bayonet mount. The pair of retention pins each extend radially outward from one of the circumferential end portions. Each of the retention pins are dimensioned to extend radially outward from the body through one of said apertures and one of said mounting slots.Type: GrantFiled: May 4, 2017Date of Patent: April 6, 2021Assignee: Rolls-Royce CorporationInventors: Brandon R. Snyder, Michael R. Whitten, James E. Sellhorn, Bradford John Riehle

Patent number: 10344596Abstract: A rotor stack assembly and method of assembling same. The rotor stack assembly comprises a tie bolt, at least one rotor disk, and a stub shaft. The rotor disk and stub shaft are carried by the tie bolt. The stub shaft is threadably engaged with a threaded end of the tie bolt and comprises a rotatable seal member and an engagement surface for contacting the rotor disk. Engagement of the stub shaft with tie bolt allows for tensioning and pre-loading of the tie bolt to desired levels.Type: GrantFiled: May 2, 2017Date of Patent: July 9, 2019Assignee: ROLLS-ROYCE CORPORATIONInventors: Michael R. Whitten, Brandon Snyder
