摘要
滚珠丝杠是数控机床、精密仪器和仪表等设备的关键零部件。旋风铣削是一种新型高效的螺纹制造技术。论文以传热学为基础研究了滚珠丝杠旋风硬铣过程中的内部热传导方程,给出ANSYS仿真结果,仿真结果表明丝杠表面与内部的温度分布规律是一致的。分析了影响温度分布的因素,为滚珠丝杠旋风硬铣过程中热变形误差的补偿提供了基础。
Ball screw is the key parts of NC machine,precise instrument and many kinds of mechanical de vices. Whirlwind milling is a new and effective thread manufacture technology. This article studies the in ternal heat conduction equations of whirlwind milling ball screw based on Heat Transfer, provided ANSYS simulation result. The simulation results show that the surface temperature distribution rule and internal tem perature distribution rule of a ball screw is consistent. The article analyzes the influence factors of the thermal elongation. It provides a basis for compensating the thermal deformation error of whirlwind milling ball screw.
