Moment of inertia of the deflection pulleys
• Can be disregarded in most applications, though in dynamic applications it may have an im-
pact on the dimensioning.
• The moment of inertia is to be entered relative to the driving pulley and has an impact on the
dynamic torque!
• The inertial moment can be estimated by means of the inertial calculator.

Moment of inertia of the belt pulley
• Can be disregarded in most applications, though in dynamic applications it may have an im-
pact on the dimensioning.
• The moment of inertia has an effect on the dynamic torque!
• The inertial moment can be estimated by means of the inertial calculator.

Symbol Description
F’ Specific travelling resistance
• Plays a minor role with regard to dynamic applications.
• Can be a rolling or frictional resistance.
• By means of the auxiliary calculator the travelling resistance can be estimated.
