Abstract

See full text

A mounting for a shaft of a tool rotating at high speed comprises a rotatably journaled tube with an axial bore of a diameter exceeding that of the tool shaft. The latter is held in that bore by resilient inserts, such as soft springs or O-rings, whose elasticity coefficient is so chosen that the shaft has a critical speed well below the operating speed of the tool. A locking device, preferably actuated automatically by a speed sensor, consolidates the shaft with the tube until the system surpasses the critical speed.
