Compliances under load and manufacturing inaccuracies of components in planetary gear sets may affect the pressure distribution on gears teeth, resulting into a significant reduction of the service life. In this work, the pressure distribution on the tooth width of a sun gear in a final drive of an off-highway axle, was evaluated by strain gauges measurements along the tooth root during a bench test of the complete axle. Tests were performed with several planet carriers to assess the effect of different manufacturing errors introduced during the assembly process. Measured data were compared with the results of a theoretical model of the final drive.

Abstract
Compliances under load and manufacturing inaccuracies of components in planetary gear sets may affect the pressure distribution on gears teeth, resulting into a significant reduction of the service life. In this work, the pressure distribution on the tooth width of a sun gear in a final drive of an off-highway axle, was evaluated by strain gauges measurements along the tooth root during a bench test of the complete axle. Tests were performed with several planet carriers to assess the effect of different manufacturing errors introduced during the assembly process. Measured data were compared with the results of a theoretical model of the final drive.Pubblicazioni consigliate
