摘要

主轴轴承组件(MSBA)对数控机床和工业设备的质量和使用寿命起着重要作用。MSBA通常基于允许磨损或刚度独立结合振动特性进行评估。因此，当磨损达到允许值，刚度降至允许值时，确定MSBA的使用寿命是非常重要的。研究了数控车床MSBA的磨损、刚度和振动特性的同步关系。结果表明，基于不同的标准(磨损量或刚度)评估MSBA的使用寿命是不同的。MSBA的刚度降至允许极限[J] = 200 N/μm，均方根(RMS)约为5.75 mm/s2。MSBA的磨损量达到允许极限[δa] = 5 μm, RMS值约为4.5 mm/s2。根据刚度准则计算的MSBA寿命比根据磨损准则计算的MSBA寿命高约1.18倍。根据磨损标准进行标准润滑的MSBA平均寿命达到~ 15,799 h, RMS达到~ 2.4508 mm/s2。

An experimental method for determining the service life and reliability of the CNC lathe main spindle bearing assembly

The main spindle bearing assembly (MSBA) plays an important role in the quality and service life of CNC machine tools and industrial equipment. The MSBA is usually evaluated based on the allowable wear or the stiffness independently combined with the vibration characteristics. Therefore, it is very important to determine the service life of MSBA when the wear reaches the allowable value, and the stiffness is reduced to the allowable value. This paper studies the simultaneous relationship of wear, stiffness, and vibration characteristics of MSBA in a CNC lathe. The results show that the service life of MSBA is different when evaluated based on each criterion (wear or stiffness). The stiffness of the MSBA is reduced to the allowable limit [J] = 200 N/μm with a Root Mean Square (RMS) value of about 5.75 mm/s2. The wear of the MSBA reaches the allowable limit [δa] = 5 μm with an RMS value of about 4.5 mm/s2. The life of MSBA calculated according to the stiffness criterion is about 1.18 times higher than that calculated based on the wear criterion. The average life of MSBA with standard lubrication according to the wear criterion reaches ∼15,799 h and RMS reaches ∼2.4508 mm/s2.
