轴承滚道旋转刷洗定位技术研究

轴承零件的表面质量是影响轴承性能的重要因素,而污渍的存在会使轴承使用寿命大大降低。本文提出一种能够让轴承零件在旋转状态下接受内外滚道刷洗的方法,应用该方法清洗轴承需对外径180~420 mm、高度95~180 mm范围内的圆柱滚子轴承、深沟球轴承进行定位,整个清洗过程采用定心机构对轴承进行定位,研究了轴承定位过程中的受力情况,并对其中涉及的轴承定位和辊刷定位精度进行分析,验证了定位机构的有效性。应用该定位机构后清洗机工件定位精度明显提高,轴承清洁度平均每套轴承最大值降低20%,相比同类辊刷清洗机生产效率提高30%以上。

Rotating Scrub Positioning Technology study of Bearing Raceway

The surface quality of bearing parts is an important factor that affects the bearing performance, and the stain would reduce the working duration of bearing greatly. A kind of method which can make inner and outer of bearing raceway scrubbed during rotating was introduced. The mechanism was applied to outer diameter of 180-420 mm, height of 95-180 mm range of cylindrical roller bearings, and deep groove ball bearing. The cleaning process of the bearing was positioned by centering mechanism. The research on stress in the process of bearing positioning, and the bearing of which involves positioning and roller brush positioning accuracy was analyzed. The effectiveness of the positioning mechanism was verified. Cleaning machine after application of the positioning obviously improved the localization accuracy of workpiece, and maximum of each bearing bearing reduced by 20% on average. The cleaner production efficiency improved 30% compared with the similar roller cleaner.
