Thickness formula
Web15 Apr 2024 · The chordal tooth thickness measurement method uses a tooth caliper that is referenced from the gear’s tip diameter. The thickness is measured at the reference circle as detailed in Figure 1. Figure 1: Chordal tooth thickness method. For spur gears, the formulas to calculate the chordal tooth thickness are detailed in Table 1. 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.
