A rotate mechanism includes a fixed frame unit, a rotating frame unit, a first bearing, and a prime mover. The rotating frame unit is rotatably coupled to the fixed frame unit and rotates about an axis. The rotating frame unit includes a first surface for receiving a machine tool element to be rotated. The first bearing is configured to exert an axially outward force on the rotating frame unit. The first bearing rotates about an axis that extends in substantially perpendicular to an axis of rotation of the rotating frame unit. The first bearing is axially movable within a cavity of at least one of the rotating frame unit and the fixed frame unit. The prime mover is coupled to the rotating frame unit to effectuate rotational movement thereof.

Mechanism and method for rotating a machine tool element

A valve stem construction for a manipulable valve member used to control fluid flow through a valve. The valve stem extends externally of the valve housing for engagement by a valve handle used to manipulate the valve member between open and closed positions. The valve is formed with a plurality of circumferentially spaced concave splines extending longitudinally on the outer surface of the valve stem. The splines are spaced so as to maximize transmission of rotational torque while minimizing flexure and twisting of the valve stem. The spacing and configuration of the individual splines also ensure a strong mating fit with the valve handle.
