The invention belongs to the technical field of nuclear power station auxiliary water supply steam-driven pumps, and particularly relates to an auxiliary water supply steam-driven pump bearing chamber rotating speed measuring device structure. Comprising a bearing chamber cover plate, a rotating speed measuring assembly and a magnetic steel device, the rotating speed measuring assembly is installed on the bearing chamber cover plate, and the magnetic steel device is installed near a pump shaft. The device has the beneficial effects that the arranged bearing chamber is specially suitable for the inlet steam-assisted pump, the newly-added rotating speed measuring device is ingenious in layout, and compact arrangement in a narrow space is achieved. The nuclear power station field implementation result shows that the structure is stable and reliable in rotating speed measurement and accurate in signal output, and the reasonability and effectiveness of the arrangement mode are verified. 本发明属于核电站辅助给水汽动泵技术领域，具体涉及一种辅
