ZAR3+ calculates the toothing efficiency, toothing and idling loss of power. The strength calculation computes the factors SF (fatigue fracture) and SH (pitting) along with tooth forces on the worm and worm gear, as well as the efficiency of the gear.
Or by varying the axial distance ratio and addendum modification you can determine the optimum worm gear for your application. In dimensioning you can adjust the recommended values to match available sizes or company standards.
The recommendations can be used in the following geometry and strength calculations. In pre-dimensioning recommendations are made for axial distance, modulus and number of teeth based on gear ratio, drive power, drive rotational speed and material. ZAR3+ calculates all dimensions of cylindrical worm gear pairs with ZI, ZA, ZK, ZN or ZH worms, as well as efficiency, tooth forces and the safety margins against root fatigue fracture and pitting.
