一、调速齿轮轴安装有误引起故障 一台S195型柴油机的调速器齿轮轴“走外圆”、轴向窜动、齿轮轴轴向间隙过大、齿轮衬套与机体止推肩磨损。经检查认为,造成这种故障的主要原因是由于齿轮轴安装有问题引起的。 其一是齿轮轴侧面油孔的安装方向不对。正确地安装方向是:轴侧面的两个小孔向下。若小孔位置偏转10度左右时,则从轴后端溅入轴入腔的机油,直接从轴前端流出,不能经油孔流入轴与衬套之间进行润滑,造成轴与衬套等零件的早期磨损。
First, speed gear shaft installation error caused a failure S195-type diesel engine governor gear shaft “take the outer circle,” axial play, gear shaft axial clearance is too large, gear bush and the body thrust shoulder wear . After checking that the main reason for this failure is due to the installation of a problem caused by the gear shaft. One is the installation direction of the oil hole on the side of the gear shaft is wrong. Correct installation direction is: the two holes on the side of the shaft down. If the hole position deflection of about 10 degrees, then from the rear end of the shaft splashed into the cavity of the oil directly outflow from the shaft front, not through the hole into the shaft and the liner between the lubrication, resulting in shaft and bushing and other parts Early wear.
