ZAR3 / ZAR3+

Software for Worm Gear Calculation

(C) Copyright 1993-2011 by HEXAGON Software, Berlin

Bases for Calculation

ZAR3 calculates all dimensions of worm gears with ZI, ZA, ZK, ZN or ZH worms, as well as efficiency, tooth

forces and the safety margins against root fatigue fracture and pitting.

Efficiency

ZAR3 calculates the toothing efficiency, toothing and idling loss of power. The program provides recommended

values and help graphics for determination of the tooth friction value. ZAR3 generates diagrams of efficiency as

function of lubricant viscosity and temperature.

Material Data Base

The program already includes a data base containing the most important gear materials and their values. Users of

the ZAR1+ spur gear and ZAR2 bevel gear programs can access this as a common data base.




5/10

Tooth Forces

Axial and radial forces, as well as tangential force and normal force are calculated. These values can be

transfered to the WL1/WL1+ software for shaft calculation.

Plus-Version ZAR3+

The extended version ZAR3+ provides additional functions: ZAR3+ generates true-scale drawing of worm and

worm gear.




6/10

ZAR3+ provides an additional input window for modifications of tooth height factors and profile shift coefficient

x. These functions are useful for design of complementary gears of steel worm and plastic worm gear.




7/10

ZAR3+ calculates tooth thickness and over pin/ball diameters (OPD). You can enter pin diameter and flank

tolerances or select from tolerance system according to DIN 3967.

Import/Export

Text printout can be generated as HTML table and exported to Excel. Input data may be loaded from an Excel

worksheet.

HEXAGON Help System




10/10

For all entries a help text or auxiliary picture can be displayed. For example, there are diagrams for input of the

tooth friction value z0 in relation to lubricant and average slide speed. There are also diagrams for optimizing the

diameter-to-center distance ratio dm1/a in relation to fatigue stress or efficiency. Users can modify and append

help texts and auxiliary pictures. When error messages occur you can have an error description and remedy

suggestion displayed.
