机电工业基金发展项目——激光测量轴承滚动体表面粗糙度,已由上海轴承技术研究所和上海交通大学联合研制成功,并通过专家鉴定。该仪器采用激光散射法测量原理,准确、快速、直观、非接触式测量轴承滚动体(如钢球、滚柱、滚针等)表面的粗糙度。与以往使用的触针式电动轮廓仪和光学干涉显微镜相 Electromechanical Industry Fund Development Project - laser measuring roller bearing surface roughness, has been jointly developed by Shanghai Institute of Bearing Technology and Shanghai Jiao Tong University, and passed the expert appraisal. The instrument uses laser scattering measurement principle, accurate, fast, intuitive, non-contact measurement of bearing rolling elements (such as steel balls, rollers, needle roller, etc.) surface roughness. With the previous use of stylus electric profiler and optical interference microscope phase
