Технологические особенности изготовления арочных зубчатых передач

Abstract

Рассмотрены технологические особенности изготовления и условия обработки закаленных цилиндрических арочных зубчатых передач и арочных конических передач с зацеплением М. Л. Новикова. Разработана методика по выбору конструкторско-технологических требований арочных передач и система "РНС-1" геометрического расчета цилиндрических, конических и реечных передач с арочными зубьями, а также унификация и сокращение номенклатуры средств производства. Проведенные стендовые испытания арочных зубчатых передач позволили создать универсальный режущий инструмент с круглыми незатылованными резцами.

Technological peculiarities of production and conditions of hardened cylindrical arched gears and arched bevel gears with meshing M. L. Novikova. Developed methodology for selection of design and technological requirements of the arched guide and the system "IR-1" geometric calculation of cylindrical, bevel and pinion gear with arched teeth, as well as unification and reduction of the range of the means of production. Bench tests of the arched gear has allowed us to create a versatile cutting tool with a round niesatynowany cutters. Conical spur, helical and herringbone gear, along with the advantages are inherent operational and technological disadvantages and in some cases do not satisfy the increasing requirements of modern gears to ensure smoothness, durability, reliability. The purpose of the design and process conditions for manufacturing an arched gears. Study of the technological features of manufacturing arched teeth at the present time is a real reserve for further enhancing the efficiency of gears and means for their production. Arched teeth allow to increase the load capacity of 1.25-1.5 times and durability in 2 - 3 times a cylindrical and a rack and pinion transmission, to reduce vibration, noise characteristics, intensity and cost. Arched teeth allow you to create a single technological system tools for the production of cylindrical, bevel and pinion gears provide smooth transmission of motion and can find application in high-speed high-load transmission.
