Normal diametral pitch of helical gears
Webnormal diametral pitch α = 1 / Pnd Whole depth of tooth Normal D.P. Divide 2.157 (or 2.25) by the normal diametral pitch ht = 2.15 / Pnd Normal tooth thickness at pitch line … WebSpan measurement of teeth, W, is a measure over a number of teeth, k, made by means of a special tooth thickness micrometer. The value measured is the sum of normal tooth thickness on the base circle , sbn, and normal pitch, pbn (k – 1). See Figure 5.4. The applicable equations are presented in Table 5.10.
