Some Results of Designing and Mastering the Series Production of a Responsible Worm Gear

Abstract

The paper considers the example of practical implementation of a technique for designing a responsible worm gear with account of high demands to smoothness of operation, contact pattern and backlash at minimum investments to modernization of manufacturing processes. Optimization design has been carried out by considering the restrictions-equalities (arrangement of gear elements, parameters of the assigned high precision standard gear cutting tool, parameters of longitudinal and profile modification of teeth), restrictions-inequalities (diameters of gear elements, gear ratio) and the purpose, that is, maximization of certain performance characteristics of the gear. Basic versions of the design solutions and their characteristics are given. Aspects of manufacturing preparation and setting of production are considered: choice of the route of gear element machining, means of gear tooling and control, investigation of the production accuracy with account of the random character of primary geometrical, controlled and functional characteristics of the accuracy. Calculation results and practical results of the assembly and control of series gears are given.
