SPUR GEARING Russian patent published in 2000 - IPC

Abstract RU 2145014 C1

FIELD: mechanical engineering, applicable in heavy-duty gearings, traction gearings of locomotives, transmissions. SUBSTANCE: the drive wheel gears of the spur gearing are made with a two-sided convex profile, the driven wheel gears are made with a two-sided concave profile. The profile radii of curvature are determined by the following dependences: for the drive wheel r1= m,z1Σ•sin(180°/z1), for the driven wheel r2= 0,5mz2Σ•tg(360°/z2), where m - modulus of gearing; Σ - gearing engagement factor; z1,z2 - number of teeth of the drive and driven gear wheels. EFFECT: enhanced bearing capacity of gearing. 2 dwg
