为了进一步改善高速精密机床电主轴的热特性
提出了一种新型轴芯冷却结构
在电主轴轴芯均布多个U形冷却单元
通入冷却介质
可对轴芯和轴承进行高效冷却; 建立了电主轴热-结构耦合分析模型
并基于模型研究了该冷却结构对电主轴热特性的影响。结果表明:该轴芯冷却结构能有效控制电主轴系统的温升
与无轴芯冷却的电主轴相比
电主轴总热变形减小了50.2%
系统热平衡时间缩短了50%
从而进一步提高了加工精度和效率; 通过调节冷却介质的参数
电主轴在不同转速下的轴向热变形的变化量可控制在2 μm以内。
To further improve the thermal characteristics of motorized spindle for high-speed precision machine tools
a novel shaft core cooling structure is proposed. This structure consists of several U-shaped cooling units arranged evenly in the shaft core
and the coolant can efficiently transfer heat of the shaft and bearings. The effects of this cooling structure on the thermal characteristics of motorized spindle are obtained based on the analysis model of motorized spindle thermo-structural coupling characteristics. The results show that the cooling structure can effectively control the temperature rise of the system. Compared with motorized spindle without shaft core cooling structure
the total thermal deformation is decreased by 50.2%
and the thermal balancing time is shortened by 50%
which enhances machining accuracy and efficiency. By regulating the parameters of coolant
the variation of axial thermal deformation can be limited to 2 μm at different rotation speeds.
