摘要： A down shift mechanism for incorporation in a device such as an assembly tool includes a wrap spring which locks and releases a planetary gear speed reduction assembly to provide shifts between two drive ratios in response to torque throughput. The wrap spring is received upon a drive drum within a cylindrical housing. The ends of the wrap spring are engaged by a pair of relatively rotationally adjustable and fixable spring engaging lugs which adjust the preload of the wrap spring and thus the torque level at which the spring unwraps and lifts off the drive drum and thus the torque level at which the shift occurs. The wrap spring housing is coupled to the ring gear of the planetary gear assembly. When the torque applied to the wrap spring exceeds the preload, the spring unwraps, unlocking the ring gear and planetary gear assembly and downshifting to the speed reduction determined by the planetary gear assembly. An alternate embodiment of the downshift mechanism is also presented.

摘要： The output shaft of a nut runner for tightening a fastener such as a bolt is first rotated with a first torque at a first speed. When the tightening torque of the output shaft reaches a preset switching torque, the first torque first speed rotation of the output shaft is interrupted, and thereafter the output shaft is rotated with a second torque at a second speed. When the tightening torque then reaches a preset snug torque, the second torque second speed rotation of the output shaft is interrupted, and thereafter the output shaft is rotated with a third torque at a third speed. When the tightening torque reaches a preset final torque, the third torque third speed rotation of the output shaft is stopped, thus completing the tightening of the fastener.
