22FTM17. A Decomposition of the Torsional Stiffness of a Worm Gearbox into Individual Components

ABSTRACT

In worm drive applications with precise transmission, the torsional stiffness of the worm gearbox is an important parameter for the positioning accuracy. The torsional stiffness is a result of elasticities from all gearbox components along the load path, which leads to various options for an optimization of the torsional stiffness within the design process of worm gearboxes. However, a targeted optimization with high effectiveness requires information about the distribution of displacements across the gearbox components.

A modeling approach is presented to decompose the total angular displacement of worm gearbox shafts under load into individual components, by which sources with high displacement proportions can be identified as targets for the optimization. The distribution of displacement proportions is investigated for specific worm gearboxes.
