Initial torque to overcome seal and nomial assembly drag. This value must be added to starting torque or operating torque values. Starting Torque: Torque value required to start moving a given load (dissipates to operating torque values once the load begins moving). Operating Torque: Torque requi...
CONSTITUTION:A torque rate RT1 on the way of fastening is found on the correlation chart of a fastening angle and fastening torque. A logical seating point is then calculated from this torque rate RT1 and a virtual torque rate RT2 is found from the fastening angle and torque values of the ...
Overall, these observations align with the characteristics associated with sagittal-parallel pedicle screw and pedicle screw trajectory, where greater consistency between screw direction and torque direction leads to more rigid fixation. Maximum stress of implants According to the contour map of stress ...
Screw Threads Calculator for Internal Unified Inch Screw Formulas Used: Note that calculated values may be slightly different than table reference data due to math rounding differences. Maximum external major diameter Eq. 1 dmax.= dbsc− es ...
Efficiency is the relationship of work input to work output. It should not be confused with mechanical advantage. Listed efficiency are theoretical values based on Kerkote® TFE coated screws. Torque The required motor torque to drive a lead screw assembly is the sum of three components: the ...
CONSTITUTION:A torque rate RT1 on the way of fastening is found on the correlation chart of a fastening angle and fastening torque. A logical seating point is then calculated from this torque rate RT1 and a virtual torque rate RT2 is found from the fastening angle and torque values of the ...
