Involute gear equations
Web10 jul. 2024 · (2) Define the involute curve via the Model->Datum->Curve->Curve Through Points. I've found that using cylindrical coordinates makes the definition less complicated. The "t" value is set to a range of 0.0 to 90.0, and the equations end up being: r = diabase * sqrt ( 1.0 + ( PI * t / 180.0 )^2 ) / 2.0 theta = t - atan ( PI * t / 180.0 ) z = 0.0 Web5.1 Chordal Tooth Thickness Measurement. This method employs a tooth caliper that is referenced from the gear’s tip diameter. Thickness is measured at the reference circle. See Figure 5.1. Fig.5.1 Chordal tooth thickness method. (1) Spur Gears. Table 5.1 presents equations for each chordal tooth thickness measurement.
