Abstract
A torque reactor employs a first socket with a first drive element engaging the first socket and a second socket with a second drive element engaging the second socket. The first drive element has a first receiving channel and the second drive element has a second receiving channel. A shaft is received in the first receiving channel second receiving channel. A first engagement mechanism secures the shaft in the first receiving channel and a second engagement mechanism secures the shaft in the second receiving channel.
Claims20
A torque reactor comprising:
- a first socket configured to engage a fastener element;
- a first drive element engaging the first socket, said first drive element having a first receiving channel;
- a second socket configured to engage a second fastener element;
- a second drive element engaging the second socket, said second drive element having a second receiving channel;
- a shaft received with a lateral gap in the first receiving channel and in the second receiving channel;
- a first releasable engagement mechanism urging a face of the shaft against a reacting face of the first receiving channel frictionally securing the shaft in the first receiving channel, thereby preventing motion of the first drive element longitudinally along the shaft when secured;
- and,
- a second releasable engagement mechanism urging the face of the shaft against a reacting face of the second receiving channel frictionally securing the shaft in the second receiving channel, thereby preventing motion of the second drive element longitudinally along the shaft when secured;
- said first releasable engagement mechanism and said second releasable engagement mechanism allowing relaxation of the shaft within the channel for translation of the drive elements longitudinally along the shaft and lateral translation of the shaft in the lateral gap relieving induced preload in the first and second socket when released.

A torque reactor comprising:
- a first socket configured to engage a fastener element;
- a first drive element engaging the first socket, said first drive element having a first receiving channel;
- a second socket configured to engage a second fastener element;
- a second drive element engaging the second socket, said second drive element having a second receiving channel;
- a shaft received in the first receiving channel and received in the second receiving channel;
- a first engagement mechanism securing the shaft in the first receiving channel;
- and,
- a second engagement mechanism securing the shaft in the second receiving channel, wherein the first and second engagement mechanisms each comprise a cap plate having a key releasably engaged on each drive element with bolts, said cap plate key engaging a groove in a top surface of the shaft urging a bottom face of the shaft vertically upon tightening to engage a bottom surface of the receiving channel, said groove and bottom surface as reacting faces thereby locking the shaft in the channel.

A method for reacting torque during torqueing of a fastener comprising:
- releasing restraining elements in at least one of a first drive element having a first receiving channel and a second drive element having a second receiving channel from a shaft received in the first and second receiving channels with a lateral gap;
- longitudinally adjusting the drive elements on the shaft to be equivalent to spacing of fasteners onto which first and second sockets are to be placed;
- placing the first and second sockets on a fastener and an adjacent fastener;
- securing the restraining elements in the first and second drive elements constraining the shaft in the drive elements;
- torqueing the fastener;
- transmitting the torque in the first socket through the first drive element and shaft to the second drive element and second socket secured to the adjacent fastener employing the arm length of the shaft between the drive elements for mechanical advantage to react the torque;
- and,
- upon completion of torqueing the fastener, releasing the restraining elements allowing lateral translation of the shaft in a lateral gap thereby releasing any preload established in the sockets.
