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）曲軸組件

　　(1) Crankshaft as

　　曲軸零件的結構主要由曲軸、平衡塊、連接套、主齒輪和減震器座組成。

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

　　曲軸為整體結構，采用優(yōu)質合金鋼擠壓鍛造而成。軸頸表面處理后，經氮化處理后具有較高的疲勞強度和耐磨性。

　　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,必須提前提供天然氣發(fā)電機組啟動和石油壓力必須在指定范圍內正常工作期間保持正常的潤滑曲軸,并防止軸頸嚴重磨損由于潤滑不良,甚至燃燒事故。

　　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)活塞連桿零件

　　(2) Piston connecting rod parts

　　燃氣發(fā)電機組的活塞連桿由活塞組和連桿組兩部分組成。

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

　　1 -氣體環(huán)(3)2 -組合油環(huán)(1)3 - 4活塞,活塞銷5 -扣環(huán)定位銷6 - 7 -連桿蓋8 -連桿軸瓦(上,下)9 - 10 -連桿連桿螺栓螺母11 -連桿機構12頭襯套活塞環(huán)槽安裝了三個空氣環(huán)和一個組合油環(huán)。使用專用工具拆卸和安裝活塞環(huán)。

　　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.

　　連桿瓦安裝在連桿和曲軸之間。裝配標記分別印在連桿體、蓋和上、下軸承襯套的同一側。

　　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.

　　連桿的上、下瓦不可互換。上瓦內表面光滑，有圓形油孔;下瓦的內表面經過油槽加工。上下瓦兩側各有一個定位唇，安裝時應正確。

　　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.
