Abstract
A rotating stick comprises a shaft, a prime mover, an outer casing and first and second bearings. The prime mover is aligned with the central axis of the shaft. The outer casing encloses the prime mover and at least partially encloses the shaft. The first and second bearings include first and second annular bodies mounted inside the outer casing. These two bodies cooperate to support the shaft in the outer casing for relative rotation. The second bearing includes a transverse surface which transfers a portion of the periodic forces propagating along the shaft to the outer casing. These forces are dissipated by the outer casing so that the energy propagated to the prime mover is minimized.
