Crank connecting rod mechanism is the main moving part of gas generator set, which is composed of crankshaft, piston connecting rod, shock absorber and connector.

　　（1）曲轴组件

　　(1) Crankshaft as

　　曲轴零件的结构主要由曲轴、平衡块、连接套、主齿轮和减震器座组成。

　　The structure of crankshaft parts mainly consists of crankshaft, balance weight, connecting sleeve, main gear and shock absorber seat.

　　曲轴为整体结构，采用优质合金钢挤压锻造而成。轴颈表面处理后，经氮化处理后具有较高的疲劳强度和耐磨性。

　　The crankshaft is an integral structure, which is made of high-quality alloy steel by extrusion forging. After surface treatment, the journal has high fatigue strength and wear resistance after nitriding treatment.

　　泵油之前,必须提前提供天然气发电机组启动和石油压力必须在指定范围内正常工作期间保持正常的润滑曲轴,并防止轴颈严重磨损由于润滑不良,甚至燃烧事故。

　　Before pumping oil, it is necessary to provide the natural gas generator unit in advance for startup and oil pressure to maintain the normal lubricating crankshaft during normal operation within the specified range, and to prevent serious wear of the journal due to poor lubrication and even combustion accidents.

　　(2)活塞连杆零件

　　(2) Piston connecting rod parts

　　燃气发电机组的活塞连杆由活塞组和连杆组两部分组成。

　　The piston connecting rod of gas generator set consists of two parts: piston group and connecting rod group.

　　1 -气体环(3)2 -组合油环(1)3 - 4活塞,活塞销5 -扣环定位销6 - 7 -连杆盖8 -连杆轴瓦(上,下)9 - 10 -连杆连杆螺栓螺母11 -连杆机构12头衬套活塞环槽安装了三个空气环和一个组合油环。使用专用工具拆卸和安装活塞环。

　　1 - gas ring (3) 2 - combined oil ring (1) 3 - 4 piston, piston pin 5 - retaining ring locating pin 6 - 7 - connecting rod cap 8 - connecting rod bearing shell (upper, lower) 9 - connecting rod bolt nut 11 - connecting rod mechanism 12 head bushing piston ring groove is installed with three air rings and one combined oil ring. Use the special tool to remove and install the piston ring.

　　连杆瓦安装在连杆和曲轴之间。装配标记分别印在连杆体、盖和上、下轴承衬套的同一侧。

　　Connecting rod bush is installed between connecting rod and crankshaft. The assembly marks are respectively printed on the same side of connecting rod body, cover, upper and lower bearing bushes.

　　连杆的上、下瓦不可互换。上瓦内表面光滑，有圆形油孔;下瓦的内表面经过油槽加工。上下瓦两侧各有一个定位唇，安装时应正确。

　　The upper and lower pads of the connecting rod cannot be interchanged. The inner surface of the upper pad is smooth and has round oil holes; the inner surface of the lower pad is processed by oil groove. There is a locating lip on both sides of the upper and lower tiles, which should be installed correctly.
