TCO optimization during design phase - Assessment of bearing concepts by calculation and simulation

Abstract

Energy efficiency has been a key issue for screw machines for many years. This article describes a new analytical procedure for determining rolling bearing friction and the use of the procedure for designing compressor bearing supports. Further analytical options for a calculative assessment of the overall efficiency of bearing support alternatives are presented in the design phase based on parameter analyses performed by the BearinX ® calculation software, which includes the new friction calculation by means of a mechanical, tribological model.
