Optimization of Cylindrical Roller Profiles
Abstract
This article introduces an optimization method for cylindrical roller profiles. Unlike traditional optimization strategies based on parametric functions, the proposed method allows each point of the profile to independently adjust its drop. This variation in drop occurs iteratively and is proportional to the contact pressure at each step. The contact pressures are computed using a numerical method based on influence coefficients. The methodology yields solutions consistent with those of logarithmic profiles. In contrast to other methods, this approach allows the incorporation of various factors, such as roller geometric constraints and tilting control. These characteristics make it a highly versatile tool. The article presents several examples and proposes a formulation for defining manufacturing tolerances.
