ZAR3 Worm Gear Calculation ZAR3+ Software for Cylindrical Worm Gear Design (C) Copyright 1993-2017 by HEXAGON Software, Berlin Bases for Calculation 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. Face widths b 1, b 2 Unit worm gear correction x Worm size can be specified using the: worm diameter factor q helix direction Оі pitch diameter.

Input Parameters Teeth type - common or spiral Gear ratio and tooth numbers Pressure angle (the angle of tool profile) О± Module m (With ANSI - English units, enter tooth pitch p = ПЂ m) Unit addendum ha.

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.

Worm Gears: Technical Information Characteristics The simplest way to obtain a large speed reduction with high torque in a compact space is with worm gear drives.

Worm gear correction x Worm size can be specified using the: worm diameter factor q helix direction Оі pitch diameter d 1 Auxiliary Geometric Calculations Design.

CHAPTER 11 Worm Gears Chapter Outline 11.1 Introduction 439 11.2 Force Analysis 446 11.3 AGMA Equations 449 11.4 Design Procedure 453 11.5 Conclusions 455 References 456 Further Reading 456 Nomenclature 457 Abstract Worm and wheel gears are widely used for nonparallel, nonintersecting, right angle gear drive system applications where a high transmission gearing ratio is required.

You should select a sensible facewidth for the worm wheel. The pressure angle at the normal section is 20В°. The worm has 2 teeth, and the worm wheel has 41 teeth.

To calculate a worm gear with center distance 100 mm.
