We will use the term Pitch (P) for both the pitch in this tutorial. The axial pitch of the worm and the circular pitch of the gear must be same for a mating worm and gear.Design calculations of the other aspects of the worm gear will be discussed in a subsequent part of the tutorial. We will use the AGMA formulae for doing the calculations. This worm gear design tutorial will discuss up to the selection of the module and pitch and the calculation of the number of teeth, pitch circle diameter and centre to centre distance between the worm and gear. Of a worm gear is related to its circular pitch and number of teeth Z by the formula.Ĭ – Centre to Centre Distance between the Worm and the Gear Worm gear.pdf - Free download as PDF File (.pdf), Text File (.txt) or read.
