You can enter pin diameter and flank tolerances or select from tolerance system according to DIN 3967.Ī true-scale drawing of worm and worm wheel, as well as tables with the gear data can be exported to CAD via the DXF or IGES interfaces. ZAR3+ calculates tooth thickness and over pin/ball diameters (OPD). These functions are useful for design of complementary gears of steel worm and plastic worm gear. ZAR3+ provides an additional input window for modifications of tooth height factors and profile shift coefficient x. ZAR3+ generates true-scale drawing of worm and worm gear. These values can be transfered to the WL1+ software for shaft calculation. The program already includes a data base containing the most important gear materials and their values.Īxial and radial forces, as well as tangential force and normal force are calculated. The program provides recommended values and help graphics for determination of the tooth friction value. 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.
