The load can be defined using torque and geometry data for a worm gear.
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, transverse module, normal pressure angle, helix angle with its direction. Optional inputs are the number of teeth for the mating gear and the center distance. The gear friction coefficient, µz, can be set for the gear contact.
