ABSTRACT:
A power torque servo system (100) for roller swaging (122), including a servomotor (132) having a gear box (134) with a drive shaft (138). The motor is supported on two members (150, 152) on opposite sides of the drive shaft (138) and a third member (146) on which the motor may pivot. Strain gages (154, 156, 158, 160) are mounted on the members (150, 152) to measure servodrive reaction torque in the shaft when the shaft is rotated by the motor to function as a swage drive or in another torquing operation. There are switches (236) to set a final torque value to be obtained in the servo system and an electrical servo system for receiving the strain gage measurement signals to provide a smooth low speed approach to a final torque value (182) in the shaft (138) and to eliminate any dynamic torque overshoot in the shaft.
