Basic Gear Terminology and Calculation | KHK Gears

The following are calculations for Center distance (a) and Tip and root clearance (c), when Module m = 2, Pinion z 1 = 20, Gear z 2 = 40 Reference diameter of Pinion d 1 = 20 × 2 = 40 Reference diameter of Gear d 2 = 40 × 2 = 80 Center distance a = (40 + 80) / 2 = 60

Cutting Formulas | Machining Formula Collection ...

First, the machined length per minute is calculated, in this case from the rotational speed and the feed amount. Machined length per minute (l) = n × f. = 0.2 × 1100 = 220 mm/min. Substitute this into the formula: Tc = lm ÷ l. = 120 ÷ 220.
