摘要
数控强力刮齿加工是一种全新的高效齿轮加工方法。针对强力刮齿技术中存在的单刃型刀具使用寿命短的问题,提出一种更为高效的新型锥形多刃刮齿刀具。根据空间交错轴啮合理论和刮齿加工齿面形成过程,建立强力刮齿加工运动模型和锥形多刃刀具切削模型。基于仿真加工软件提出一种用于分析多刃刮齿刀具切削成形过程的模拟方法,给出了仿真模型设置、仿真切削加工步骤,并通过对比仿真切削加工结果,分析了多刃型刮齿刀具和单刃型刮齿刀具在切削成形过程中的异同,验证了锥形多刃刮齿刀具的可行性。为研究圆柱齿轮的多刃高效展成成形机理和研制新型锥形多刃刮齿刀具提供理论依据。
Numerical control power skiving is a modern and productive method in the manufacturing of cylindrical gears.Aiming at the problem of short service life of single-edge tool in powerful tooth skiving technology,a novel skiving tool with multiple blades with higher efficiency is proposed.Based on the meshing theory of crossed axes and the cutting process of tooth surface in gear skiving,the kinematics model of powerful tooth scraping and the cutting model of tapered multi-edge cutter are established.By using the machining simulation software,a simulation method for the analysis of the forming process of multi-blade gear cutters,simulation model setting and simulation cutting procedure are given.By comparing the simulation cutting results,the similarities and differences between multi-blade and single-blade are analyzed,and the feasibility of tapered multiblade skiving tool is verified.The study results provide the theory basis for the productive generating mechanism of cylindrical gears and the development of multi-blade skiving tool.
