| 摘 要： | 分析了高速电主轴的两个热源,轴承发热和电机的发热,并计算了轴承和电机的发热量.分析了高速电主轴的散热特性,并对电主轴各部分散热系数进行了计算.以HMC80卧式加工中心电主轴为例,运用ANSYS有限元软件建立了电主轴的稳态热分析模型,以散热系数为边界条件,轴承和电机的发热量为热载荷进行有限元分析,得出该电主轴在热稳定状态下的温度场分布.分析结果表明,主轴前后轴承的温升符合该电主轴的温升标准,说明了该电主轴设计的合理性,最后提出了改善该电主轴热态特性的措施. |

| Abstract: | Two heat sources and thermal properties of the high-speed spindle are analyzed,and the heat of bearing and motor as well.Meanwhile heat value for the bearing and motor and the radiating factors of parts of the spindle are calculated.Taking spindle of HMC80 as an example,steady-state thermal analytical model for the spindle is established through applying ANSYS finite element software,and FEM analysis is carried out based on cooling coefficient of thermal boundary conditions,and taking heating value of beari... |
