Country-neutral calculator for Duz Gear Geometry and Aktarma Preliminary Analysis - Pres Line Hatve Diameter.
Use consistent units and the requested inputs.
Use the main result and breakdowns as a planning estimate.
For regulated topics, verify current local rules before acting.
d = m z (mm, reference pitch diameter)
Inputs: m=3 mm; z=40 ; calculate using stated formula.
Ideal preliminary shaft transmission values; actual ratios, capacity and efficiency require manufacturer verification.
Ideal steady-state power transmission calculations only; not a certified belt, chain or gear design. Belt diameters must be effective pitch diameters, not arbitrary outside diameters, and slip, elongation, belt wrap, tension, belt selection, thermal effects and efficiency may alter actual speed and loading. Belt/chain counts are rounded up nominal catalog-capacity screening and require service, size and installation verification. Chain speeds are time-averaged pitch travel values and neglect chordal speed variation; teeth must be whole numbers. Gear models assume matched module and ideal geometry; tooth contact, bending, undercut, interference, lubrication and geometry corrections are not checked. Torque coefficient 9550 approximates exact 60000/(2π). Stop-state zero speed is valid for speed models; zero RPM cannot be used as divisor in a power-to-torque model. Numeric guards are computational limits, not manufacturer ratings.
