通过对LM11949／10、NU211等轴承零件作单因素交叉试验和对国外同型号产品振动对比分析，找出了圆锥滚子轴承诸零件对轴承振动的影响规律，尤其是找出了滚子波纹度是影响轴承振动加速度和振动速度高频档的主要因素。通过两项企标实施和采取降振措施，收到了明显效果。附图2幅，表5个。 Through the single-factor cross test on LM11949 / 10, NU211 and other bearing parts and comparative analysis of the vibration of the same type of foreign products, the influence laws of the parts of tapered roller bearing on bearing vibration were found, especially the roller waviness Is the main factor affecting the bearing vibration acceleration and vibration speed high frequency file. Through two enterprises to implement and take measures to reduce vibration, has received significant results. Figure 2, Table 5.
