Power Losses Estimation in Precessional Gear

Abstract

Having established the estimation relations of power losses in basic kinematical joints, it becomes relatively simple to establish the estimation relation of kinematical precessional transmission efficiency which, on the whole, is equal to the product of the two components (efficiency of sliding bearings and gear efficiency). On the basis of the obtained relation, an algorithm for the estimation of power losses in the kinematical precessional transmissions will be elaborated. Also a series of graphs for various geometrical and kinetostatic parameters will be produced. This thing will be useful to designers who will estimate quantitatively kinematical precessional transmissions at the phase of design.
