Abstract
A stabilizer for a steady rest is disclosed for supporting rotating cylindrical members during machining operations and the like that includes idler wheels supported by air jacks that allow limited lateral movement of idler wheels to accommodate at least some of the lateral movement of the rotating member that results when the member is crooked. Shock absorbers are positioned to dampen the lateral movement of the idler wheels to reduce the vibrations such lateral movement of the rotating member may produce at the surface being machined.
Claims3
A steady rest for supporting a cylindrical member for high speed rotation during machining operations comprising a pair of idler wheels, means supporting the idler wheels for rotation around axes parallel to the longitudinal axis of a cylindrical member supported by the idler wheels, a pair of air cylinders having curved flexible walls or resilient material in side-by-side position below the idler wheels to support the idler wheel support means to allow limited lateral movement of the idler wheels to accommodate the tendency of the cylindrical member to move back and forth laterally as it is rotated on its longitudinal axis if it is not straight, base means supporting the air cylinders, and shock absorbing means connected between the base means and the idler wheel support means to assist the air cylinders in resisting the lateral movement of a nonstraight cylindrical member rotating rapidly on the idler wheels.
