1、凸輪軸

凸輪軸裝在機體V型夾角中央座孔內。按一定方位順序排列24個凸輪,驅動滾輪搖臂上下擺動,經挺桿及氣缸蓋上的氣門搖臂和搖臂橫橋,定時地控制著兩個同名氣門啟閉。

The camshaft is installed in the central seat hole of the V type angle of the engine block. 24 cams are arranged in a certain direction, and the driving roller rocker swings up and down. The valve rocker and rocker arm transverse bridge on the tappet and the cylinder head are used to control the opening and closing of the two valves of the same name.

2、滾輪搖臂組件

D88尊龙瓦斯發電機組的滾輪搖臂軸由三段結構完全相同的軸組成,每段滾輪搖臂軸上均裝有四個滾輪搖臂,分別控制對稱布局的兩個氣缸的進、排氣門開、閉。

The shaft is composed of three segments of the same structure of the roller rocker shaft gas generator set, each roller rocker shaft is provided with four roller rocker, two cylinders respectively control the symmetrical layout of the inlet and outlet valve open and close.

3、配氣機構的工作過程

3. Working process of valve train

在瓦斯發電機組正常工作過程中,曲軸通過齒輪的傳動,帶動凸輪軸運轉。由于凸輪桃型曲線的原因,當某個凸輪的挑形與其對應的滾輪搖臂接觸時,該滾輪搖臂就以滾輪搖臂軸為軸心向上轉動,推動挺桿向上運動,將進氣搖臂一端頂起,另一端則下壓橫橋中部,橫橋兩觸頭與兩同名氣門桿頂部同時接觸,克服氣門彈簧阻力,將兩同名氣門壓開。當凸輪的挑形轉離與其對應的滾輪搖臂時,兩同名氣門就在氣門彈簧的作用下恢復到關閉狀態。

During the normal operation of the gas generator set, the crankshaft drives the camshaft through the transmission of gears. Due to the cam curve, when the corresponding pick shaped roller rocker contact a cam, the roller rocker on the roller rocker shaft axis to rotate, push upward movement, the intake from the top of one end of the rocker arm, the other end is under middle pressure cross bridge, cross bridge and two contact two of the same name at the top of the valve rod at the same time, to overcome the resistance of the valve spring, valve opening pressure will be two of the same name. When the cam is turned away from its corresponding roller rocker arm, the two valve with the same name will resume to the closed state under the action of the valve spring.
