PULSE MOTOR NUTRUNNER

摘要

A non-impacting nut running pneumatic tool in which torque pulses are transmitted by an oscillating air motor through a oneway clutch and reduction gearing to the work. A torque responsive cam clutch member responds to a predetermined delivered torque to cause stalling of the motor by blocking off escape of exhaust air and to cause discontinuance of further torque transmission to the work by disabling the drive connection. Manually operable adjusting means is provided to regulate the value of torque delivered.
