  • Torque-applying tool and torque controller therefor
    Patent number: 9022135
    Abstract: A torque applying system includes a torque applying tool having a motor and rotating output spindle, a torque sensor that measures an instantaneous torque exerted by the output spindle during a fastening cycle, and a controller operatively connected to the tool to control the tool's rotational speed during the fastening cycle. The controller is programmed to control the tool's rotational speed to be [(?F??C)/t]/r, wherein t is a time constant of speed control, ?F is a target final torque for the fastening cycle, and r is a torque rate.
    Type: Grant
