Calculation of gears

The calculation is made on the basis of GOST 21354-87 (hereinafter - the Standard) "Cylindrical gears involute external engagement for strength calculation.". The standard establishes the basic design according to the definition of the contact strength of the active surfaces of the teeth and tooth strength at bending metal cylindrical involute external gear transmission for general industrial applications with source circuit in accordance with GOST 13755-81, modulus m / 1 mm, working with lubrication oil at peripheral speeds v<=25 m/s.
