The invention relates to a stern tube bearing trial running-in method in ship trial voyage. The method comprises the steps of ship stern tube bearing trial running-in; continuously monitoring the temperatures of a stern tube bearing, all intermediate bearings, a host and a gearbox thrust bearing; the stern tube bearing test running-in process is divided into four corresponding stages according to the four gears of a marine main engine telegraph from the lowest speed, the low speed, the medium speed, the high speed and the full speed. If abnormal conditions occur, immediately adjusting the rudder angle to zero and reducing the rotating speed of a main engine; and when the temperature of the stern tube bearing recovers to a normal working state, determining and removing the fault, and restarting the stern tube bearing test running-in. According to the stern tube bearing trial running-in method in the ship trial run, steering is conducted according to the navigational speed from low to high through slow small rudder angle operation, stern tube bearing trial running-in can be conducted step by step, and the situation that the stern tube bearing is prone to being damaged before the ship trial run or in the trial run process is effectively prevented and avoided. And when the stern tube bearing is subjected to high-temperature alarm and even the stern tube bearing is invalid and scrapped, the safety of ship operation is effectively improved.
本发明涉及一种船舶试航中艉管轴承试磨合的方法,包括船舶艉管轴承试磨合;连续监测艉管轴承、所有中间轴承、主机、齿轮箱推力轴承的温度;按照船舶主机车钟从最低速度、慢速、中速、快速、全速这四档,将艉管轴承试磨合过程分为对应的四个阶段;出现异常情况,立即将舵角调整为零并降低主机转速;当艉管轴承温度恢复至正常工作状态,确定并排除故障后,重新开始艉管轴承试磨合。本发明的一种船舶试航中艉管轴承试磨合的方法,通过缓慢小舵角操作,按照航速从低到高的顺序进行操舵,使艉管轴承试磨合可以循序渐进,有效预防和避免在船舶试航前或试航过程中,艉管轴承发生高温报警甚至艉管轴承失效报废等情况,有效提升了船舶营运的安全性。
