全苏铁道运输科学研究院乌拉尔分院设计了一种滚柱轴承振动声学诊断检验台。它可供轮对车间对轴箱作不拆卸的中间检查时检查轴承的技术状态。用2t单梁吊车将轮对吊装于检验台上。检验台能自动显现轴承滚子内外环滚动面、内外环工作凸肩上和轴承滚柱端面上的缺陷,因为这些缺陷会使承载状态下的轴承旋转 All-Ursula Branch of the Academy of Railway Transport Science and Technology has designed a vibration-acoustic diagnostic test stand for roller bearings. It can be used to check the technical status of the bearing when the wheel does not disassemble the intermediate box in the workshop. Use 2t single-beam crane to hoist the wheel on the inspection platform. Inspection table can automatically show the bearing roller inner and outer ring rolling surface, inner and outer ring work shoulder and bearing roller end defects, because these defects will make bearing bearing rotation
