Te Lewis equation is a fundamentaltal method used to estimate thee bending equath of gear teeth. It provided a simplified way to asses whether ther a gear can with stand operation l loads without out failure. Thies article explains thee applicatin of thee Lews equation in gear design and analyses.

Uzgodnienie to Lewis Equation

Te Lewis equation relates thee bending stress in gear teeth te gear 's geometry andd load conditions. It considers thee gear tooth as a cantilever beam subieted to a load at thee tip. The basic form of thee equation im:

Appliing the Lewis Equation

To jest to, co jest w tym wszystkim ważne.

Kiedy T is thee torque and d is the pitch diameter. Once thee force is known, substitute into the Lewis equation to find thee bending stress.
