摘　　要：落地镗铣床加工范围广泛,不受导轨副与传动链的影响。主轴系统是落地镗铣床的核心部件,主轴轴承温度控制是保证机床切削精度的重要因素。从结构设计、组件选配、轴承游隙控制、冷却循环和润滑方式等方面进行分析,有效控制主轴轴承温升,提升主轴的运行稳定性与精度。The floor boring and milling machine has a wide processing range,which is not affected by the guide rail pair and the transmission chain.The spindle system is the core component of the floor boring and milling machine,and the temperature control of the spindle bearing is an important factor to ensure the cutting accuracy of the machine tool.This paper analyzes the structure design,component selection,bearing clearance control,cooling cycle and lubrication mode to effectively control the temperature rise of the main shaft bearing and improve the stability and accuracy of the main shaft.
