METHOD AND APPARATUS FOR APPLYING TORQUE

摘要

One example of the present disclosure relates to a method of applying torque to an object, which threadably engages a part. The torque is applied with a wrench, comprising a first handle, a second handle, a planetary gear mechanism, a drive that comprises an internal gear and an external gear, and a first pawl, movably coupled to the first handle and biased to contact the external gear of the drive. When the drive is coupled to the object, the method comprises transmitting an input torque to the drive by rotating at least one of the first handle and the second handle relative to the part. The first pawl is movable between a first position and a second position relative to the first handle may or may not operatively engage the external gear of the drive.

1. A method of applying torque to an object, threadably engaging a part, with a wrench, comprising a first handle, a second handle, a planetary gear mechanism, a drive that comprises an internal gear and an external gear, and a first pawl, movably coupled to the first handle and biased to contact the external gear of the drive, the method comprising:
when the drive is coupled to the object, transmitting an input torque to the drive by rotating at least one of the first handle and the second handle relative to the part,
wherein the first pawl is movable between a first position and a second position relative to the first handle, andwherein:
the drive rotates in a first direction relative to the part when the first handle is rotated in the first direction relative to the part, the first pawl is in the first position, and the first pawl operatively engages the external gear of the drive;the drive rotates in the first direction relative to the part when the first handle is rotated in a second direction relative to the part opposite to the first direction, the first pawl is in the first position, and the first pawl does not operatively engage the external gear of the drive;the drive rotates in the second direction relative to the part when the first handle is rotated in the second direction relative to the part, the first pawl is in the second position, and the first pawl operatively engages the external gear of the drive; andthe drive rotates in the second direction relative to the part when the first handle is rotated in the first direction relative to the part, the first pawl is in the second position, and the first pawl does not operatively engage the external gear of the drive.
