高速电主轴冷却系统模型建立
|
摘要
本文研究高速电主轴在不同转速下的温度变化,由于电主轴属于内装式电机,电主轴所产生的热量不容易散出。为了防止电主轴温度过高而引起的精度降低,研究了发热部位以及传热方式、深入剖析了影响电主轴温度的相关冷却参数,通过大量实验数据与传热的理论基础拟合出电主轴温度与冷却参数的函数关系,建立了电主轴冷却的参数模型。实验证明这种方法建立的模型准确,为以后完善温度控制模型提供了重要根据。
This paper discussed the temperature field of high speed motorized spindle under various speed conditions,because the type motorized spindle belongs to built-in motor so that the heat which the motored spindle produced could not dissipate out. In order to prevent the motorized spindle from high temperature which would cause the low accuracy,the parts which produce heat and heat transfer mode are studied,then the coolant parameters which affect the temperature are analyzed. This paper fitted function related to the temperature of high-speed motorized spindle and the coolant parameter based on heat transfer theory and a large number of experimental data,and the coolant parameter model is built. Other experiment proved the model was accurate,and this paper provided important model foundation for further building the temperature control model of high speed motorized spindle.
