摘要

辊磨减速机静压轴承表面巴氏合金存在贯穿划痕并伴有铁质杂质镶嵌，同时，输出法兰推力面上存在同心圆形状的沟槽拉伤，此损伤降低了辊磨减速机运转可靠性，易引发设备事故。经拆解减速机、清理高压油分配器内置单向阀、检查润滑油输送管路，找到了润滑油中铁质杂质产生的原因。通过采取将柱塞式高压油泵更换为齿轮式高压油泵，加强润滑油质的日常检测等措施，消除了设备运行隐患，提高了辊磨减速机运转可靠性。

Abstract:

Babbitt metal on the hydrostatic bearing surface of the roller mill reducer has through scratches and iron impurities embedded, and at the same time, concentric grooves are pulled on the thrust surface of the output flange, which reduces the operational reliability of the roller mill reducer and easily leads to equipment accidents. After disassembling the reducer, cleaning the one-way valve in the high-pressure oil distributor, and checking the lubricating oil delivery pipeline, the causes of iron impurities in lubricating oil were found. By replacing plunger-type high-pressure oil pump with gear-type high-pressure oil pump and strengthening daily inspection of lubricating oil quality, the hidden trouble of equipment operation is eliminated, and the operational reliability of roller mill reducer is improved.

Key words: roller grinding hydrostatic bearing high pressure oil pump reducer
