A PARTICULAR OPERATION OF THE SYNCHRONOUS MACHINE AND ITS TECHNICAL IMPLICATIONS

Aurel CÂMPEANU

Abstract


The article is dedicated to the research of precessional transmissions (PT) with multipair convex concave gears . Aspects regarding the elaboration of precession gearing with multipair convex-concave tooth contact, the structural synthesis of the transmissions, the kinematics and tooth contact bearing are described. The influence of the geometric and kinematic parameters of the convex-concave gear on the relative sliding with friction between the mating flanks of the teeth and on the reduced curvature of the multipair mating flank profiles, and the bearing capacity and mechanical efficiency of the gear, respectively, is examined. The paper deals with technological procedures for generating non-standard tooth profiles by rolling with a spherospatial motion tool, as well as by generating them in the Gleason system on numerically controlled machine tools. Constructive-functional applications of kinematic and low-power precessional transmissions are described.
