PRELIMINARY ESTIMATE OF POWER LOSSES IN ECCENTRIC TRANSMIS-SION CONTACT PAIRS WITH PARALLEL INPUT AND OUTPUT SHAFT AR-RANGEMENT

Abstract

The article presents one of the variants of the structural scheme of the eccentric type transmission, in which the input and output shafts are located in parallel. The design of an eccentric transmission with translational motion of a satellite having external teeth that are involved with the inner teeth of the output central wheel is proposed. For this transmission option, an analytical formula for mechanical losses in contact pairs from the angle of rotation of the main crank is given. An example of calculating the output center wheel is given. An example of the calculation of the output center wheel is obtained mechanical losses with the receipt of initial data by means of computer modeling. The graphical dependence of mechanical losses in the considered variant of eccentric transmission on the basic geometric parameters is obtained. The developed method of preliminary estimation of power losses in an eccentric transmission with a parallel arrangement of the input and output shafts can serve as the basis for optimizing the geometry according to the criterion of the maximum efficiency value.
