The Calculus of the Equivalent Rigidity Coefficients for the Shafts of the (/$67,&$/ Systems

The components of the mechanical systems like machines and/or technological equipment have a certain elasticity or rigidity. Knowing the rigidity of each component is very important for the studies whose goal is to establish the dynamic efforts and the stresses in each shaft, gear wheel, steel structure, aso. The rigidity can be an important factor for the dynamic load estimation process. The components with high elasticity are the most important inducers of elastical forces and couples of force; we can enumerate: shafts, coupling gears, gears, elastical couplings, springs, long steel structures, some working devices, aso. This article presents a method and an equation involving the rigidities of the elastical shafts of the mechanical transmissions with gears in any point of the system, so that the dynamic analysis should become easier.
