| titleOfInvention | Power torque tool |
| abstract | A power torque tool has an output shaft (18) along which torque pulses are transmitted to a load (28) such as a bolt. The shaft is driven by a mechanism (16) which can be of the impact-type or piston-and-cylinder type. The torque in the shaft (18) is measured by an integral region (30) of the shaft (18) which stores a remanent magnetisation which emanates a torque-dependent magnetic field. The field is sensed by non-contacting sensor arrangement 34. The torque impulses may be processed (36) to control the operation of the primary motor (14) so as to stop the motor when a predetermined torque is reached. The nature of the torque pulses generated in a power torque tool is analysed together with procedures for processing the pulses. The measurement of torque loss in torque pulse transmission along a shaft is disclosed. |
