A seal assembly has a pair of duo-cone seals positioned by a like pair of torics for axial loading. An insert member of flexible material is located within the member defining one of a pair of confronting inclined surfaces operatively containing the torics. The flexible insert members are not susceptible of oxidation when exposed to the atmosphere.

Duo-cone seal flexible mounting

A drive assembly having a shroud structure for providing a low friction covering of securing elements which, in projecting from a rotation portion of the drive assembly, would otherwise cause a power and efficiency loss as the result of a friction drag produced in movement of the projecting elements through a body of lubricating and cooling fluid. The shroud structure is secured to the rotating element by securing structure received in recesses in the shroud to further effectively minimize friction drag losses.
