摘要
根据课题总体目标设计了符合要求的高速精密数控车床电主轴,主要包括轴系参数的计算,冷却、润滑和密封装置的设计。其中轴系参数计算主要包括主轴轴径计算和轴承的选配和校核。在结构设计中,考虑到前轴承和转子的冷却、轴承的润滑及结构的密封问题。电主轴装入ADGM高速精密数控车床中进行试切,结果表明,车床的加工精度、进给速度和加工速度等各项参数都符合指标,证明了该主轴设计合理。
Design the spindle to meet the requirements of high speed and precision CNC lathe according to the topic goals, including calculate the parameters of shaft, design the device of cooling, lubrication and sealing. The calculations parameters of shaft mainly include calculate diameter of spindle and select and checking the bearing. In structural designing, takes into account the problems of the cooling of the front bearing and rotor, the lubrication of bearings, the seal of structure. Packed spindle in ADGM high-speed precision CNC lathe to try cutting, the results confirmed that, the lathe parameters of machining accuracy, feed speed and processing speed and so on meet the targets, prove the design of spindle is reasonable.
