The load can be defined using torque and geometry data for a worm.
The direction of torque can either be defined by its sign or by the selection “Shaft is driven”/Shaft is driving”. The contact point is given by an angle of contact, which is zero on the y-axis and 90° on the z-axis. The gear is defined by the usual data on a gear drawing: Number of teeth, axial module, normal pressure angle, lead angle with its direction. The gear friction coefficient, µz, can be set for the gear contact.
