摘　　要：介绍了直接空冷机组冷却风机及减速机布置和磨损情况,对减速机断油后轴系磨损原因进行了分析,指出减速机轴系磨损是油压表破裂引起跑油,而油压低,保护虽然动作但仍不能有效防止轴系的磨损,从而提出了防护措施。An introduction is being presented to arrangement and wearing status of the cooling fan and reduction gear in a direct air-cooling unit, together with a cause analysis performed to shafting wearing of the reduction gear after oil-break. It is pointed out that the failure is caused by oil pressure gauge breaks, which result in oil escape and low oil pressure, and the shafting wearing cannot be prevented effectively though the protection actions. Protection measures are finally put forward accordingly.
