目前圈内大多数单缸柴油机主轴承和连杆轴承的润滑路线为:油底壳→吸油盘→机油泵→油管→机油滤清器→油管→主轴承盖→主轴承油孔→曲轴斜油道→连杆轴承,不仅油路路线长,联接处多,容易产生泄漏,特别是飞轮端曲轴油封处漏油十分常见。此外曲轴上还需加工“人”字形斜长油道,加工困难。为此,我厂EM180、185系列柴油机采用如图1 At present, most of the single-cylinder diesel engine main bearing and connecting rod bearing lubrication routes: sump → sucker → oil pump → tubing → oil filter → tubing → main bearing cap → main bearing hole → crankshaft oblique oil Road → connecting rod bearings, not only long route oil, joints and more prone to leakage, especially the flywheel end of the oil seal seal is very common. In addition, the crankshaft also need to process “” glyph inclined long oil, processing difficulties. To this end, I plant EM180,185 series diesel engine using Figure 1
