Interference Detection Method on Stationary Internal Toroidal Gear Based on Discrete Model

Abstract

Abstract: An interference detection method was put forward to effectively solve the problems of machining local and global interference phenomenons on stationary internal toroidal gear tooth surfaces. The introduction to interference detection plan clusters and the structure of interference detection line clusters were to obtain stationary internal toroidal gear tooth surface and tool scanning body discretization model. By using stationary internal toroidal gear tooth surface and tool scanning body discretization model, and through solving the cutting plane tool centers, stationary internal toroidal gear tooth surface machining local and global interference areas were determined. And through the example analyses, the feasibility of machining interference detection method of stationary internal toroidal gear tooth surface was further verified.

摘要： 针对内超环面齿轮齿面加工局部和全局干涉现象，提出一种干涉检验方法，有效地避免了加工干涉。通过干涉检验面簇的引入和干涉检验线簇的构造，将内超环面齿轮齿面和刀具扫掠体离散化。运用内超环面齿轮齿面和刀具扫掠体离散模型，通过截平面处刀具中心的求解，确定内超环面齿轮齿面加工局部和全局干涉区域。通过实例分析进一步验证了内超环面齿轮齿面加工干涉检验方法的可行性。
