Abstract:
Disposable torque-limiting devices having an upper shank component with a torque-limiting interface, a lower shank component with a torque-limiting interface, and a spring element. Torque-limiting interfaces having a plurality of undulations arranged around an axial bore or drive socket and separated by a plurality of transition regions, with each undulation having an upslope, a peak, and a downslope. The torque-limiting interfaces are configured to engage and disengage to provide torque transmission with predetermined torque limits at various rotational speeds and for amounts of actuations while remaining within a specified operational range. The encasement provides mounts for a tool and for a drive shaft which may be connected to a powered device.

Claim (Index 1):
A disposable torque limiting device comprising:\n a generally hollow cylindrical body ( 14 ) with a partially closed distal end ( 16 ); an upper shank ( 200 ) formed inside the partially closed distal end of the cylindrical body; a circumferential rim ( 17 ) formed on the outside of the partially closed dial end; an upper torque-limiting interface ( 250 ) formed on the inside of the partially closed distal end having a axial bore ( 210 ); a lower shank component ( 100 ) within the cylindrical body comprising a proximal end ( 101 ), a distal end ( 102 ), a neck ( 125 ) extending from the distal end a drive socket ( 110 ) fluidly connecting the proximal end and the distal end, and a lower torque-limiting interface ( 150 ) disposed on the proximal end, wherein the upper shank component and the lower shank component are aligned along an axis ( 50 ) in the direction of the axial bore and the drive socket with the first torque-limiting interface in contact with the second torque-limiting interface; a coil spring ( 30 ) placed above the lower shank on at least partially around the neck configured to apply compressive force (F) along the axis to compress the first torque-limiting interface against the second torque-limiting interface; a tool collar ( 20 ) with a flange ( 22 ) extending radially, a front ( 23 ) on one side of the flange, a square leg ( 25 ) formed on the opposite of the flange and a shaped channel ( 29 ) there through rotatably fit into the circumferential rim; a tool shaft ( 32 ) with a threaded back portion ( 35 ) and a front end ( 31 ) having a tool channel ( 34 ) therein; catches ( 33 ) formed on the tool shaft configured to mate with the shaped channel whereby the tool shaft can be inserted through the tool collar but rotate within the shaped channel; a threaded ( 37 ) retaining member ( 38 ) configure to engage the threaded back portion; and, wherein the tool shaft and threaded retaining member cooperate to apply a predetermined force to the lower and upper shanks by affixing the tool shaft through the tool collar, the axial bore, the drive socket and the coil spring and affixing the retaining member thereto.
