Worm Gear Gears
The Worm Gear Ratio Calculator is a valuable tool designed to determine the gear ratio between a worm gear and a worm wheel (or gear) in mechanical systems. This ratio helps in understanding the rotational speed and torque transfer between these interlocking gears.

1 Scope. This document specifies formulae for calculating the load capacity of cylindrical worm gears and covers load ratings associated with wear, pitting, worm deflection, tooth breakage and temperature. Scuffing and other failure modes are not covered by this document. The load rating and design procedures are only valid for tooth surface.

Worm gears are quiet in operation. Worm gears at the higher ratios are inherently self locking - the worm can drive the gear but the gear cannot drive the worm. A worm gear can provide a 50:1 speed reduction but not a 1:50 speed increase..(In practice a worm should not be used a braking device for safety linked systems e.g hoists. .

(1) Standard Spur Gear Figure 4.1 shows the meshing of standard spur gears. The meshing of standard spur gears means the reference circlesof two gears contact and roll with each other. The calculation formulas are in Table 4.1. Fig. 4.1 The Meshing of Standard Spur Gears ( α=20°, z 1 =12, z 2 =24, x 1 =x 2 =0 )
Competence in worm gear units for more than 120 years • AUMA Drives
The worm and hob lead angle calculator calculates the lead angle for a worm gear or gear hob based on its diametral pitch (1/in) or module (mm). This ultimately controls the spacing between teeth on the worm (just like the threads per inch, or pitch, of a screw). The pitch diameter of a worm gear or gear hob can be used as its effective.

Worm gear sets are generally rated by their capacity to handle a particular level of input power, output power, or allowable torque at a particular speed for the input or output shaft. The AGMA power rating is based on pitting and wear resistance, as this is the usual failure mode for worm sets.

Composite Worm Gears Extend Wear Life in Tough Applications
ZAR3+ generates true-scale drawing of worm and worm gear. 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. ZAR3+ calculates tooth thickness and over pin/ball diameters (OPD).
