Abstract

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.
