Method of treating bearings with ultrasonic vibrational energy

Abstract

Abstract ELECTRICAL-MECHANICAL VIBRATION TRANSDUCER MEANS ARE EMPLOYED TO INTRODUCE MECHANICAL VIBRATIONS INTO THE RACE OF A SWAGED SPHERICAL BEARING TO STABILIZE THE RACE, REDUCE SWAGING FORCES REQUIRED, ELIMINATE "SPRING BACK" OF THE RACE AWAY FROM THE INNER BEARING MEMBER, AND TO PRODUCE A DESIRED PRELOAD TORQUE VALUE BETWEEN THE INNER AND OUTER BEARING MEMBERS, AN ACCELEROMETER MEANS IS PROVIDED FOR MEASURING THE AMPLITUDE OF VIBRATIONS OF THE BEARING RACE TO DETERMINE THE RESONANT FREQUENCY OF THE RACE OR RACE AND ASSOCIATED SWAGING DIES OF A SWAGING PRESS OR PILLOW BLOCK OF A PRELOAD MEASURING APPARATUS, THE METHODS AND MEANS FOR APPLYING AND TERMINATING THE APPLICATION OF VARIABLE FREQUENCY OSCILLATIONS TO THE TRANSDUCER MEANS.
