The optimization of the ribbing of gear transmission housing used in transportation machines

The present paper discusses results of simulation tests conducted using an identified dynamic model of a laboratory station with gear transmissions. The dynamic forces found to be acting in bearing assemblies were assumed as input functions for the purposes of studies of the numerical housing models developed. Using fine-tuned modal housing models in the analysis of the design solutions applied allowed for choosing appropriate arrangement of the transmission ribbing. By analyzing the shape of the ribbing layout envisaged as well as its structural characteristics (height and width of ribs), one could choose a housing of reduced vibroactivity and mass.
