Abstract

A machine for mass-centering rotors consists of a pair of spaced apart headstocks, each rotatably supporting an adapter disc, and each equipped with a device for the application of machining centers in a rotor being investigated. Adjuster mechanisms on the adapter discs are removably secured to the ends of the rotor, whereby rotation of the discs causes the rotor to rotate. The headstocks are connected to a vibration sensing vibratory bridge arrangement which picks-up the vibration of the rotor as it rotates. The adjuster mechanisms shift the axis of rotation of the rotor until the unbalance thereof is zero or at a predeterminable level. Rotors of differing length are easily positioned between the headstocks which move toward and away from one another.
