METHOD OF TORSION SHAFT ELASTICITY RESTORATION Russian patent published in 2000 - IPC

Abstract RU 2161276 C1

FIELD: thermomechanical treatment of shafts. SUBSTANCE: method includes heating, surface plastic deformation and cooling. Heating, twisting and surface plastic deformation are continuously performed, in succession, along torsion shaft length. Twisting of every heated section is performed through angle ϕ01

calculated by formula

, where x is distance from torsion shaft end to section being heated (without shaft spline part, m; L is torsion shaft length (without shaft spline part), m; ϕ⁰ is limiting twisting angle of torsion shaft which service life completed, deg. EFFECT: extended process capabilities. 7 dwg, 1 tbl
