Pre-tensioning torque of the locknut

MV = Pre-tensioning torque of the locknut [Nm]

FV = Required axial pretension force of the threaded connection [N]

B = Locknut-specific allowance [N], compensates face end relief due to the locking process

A = Constant [mm], includes the calculation factors for the respective thread width (catalogue value)

µA = Frictional coefficient for the end contact surface of the locknut Approximate value μA = 0.1 steel/steel

rA = Effective friction radius for the end contact face of the locknut [mm]

Tightening torque per set screw (from locknut size MSW > M70)

MD = Tightening torque per set screw [Nm]

FV = Required axial pretension force of the threaded connection [N]

A = Constant [mm], includes the Calculation factors for the respective thread width (catalogue value)

µD = Frictional coefficient for the end contact face of the set screw, Approximate value = 0.13

d6 = Dog point dia. of the set screw [mm] (catalogue value)

n = number of set screws

Transmittable torque (Clamping sets)

M = Transmittable torque (catalogue value) [Nm]

Me = Required torque [Nm]

Mr = Resulting torque [Nm]

Fae = Required axial force [N]

d1 = Shaft diameter [mm]
