卡特彼勒CAT柴油發動機曲軸修理技術

Caterpillar CAT diesel engine crankshaft repair technology

卡特彼勒CAT柴油發動機曲軸使氣缸內的燃燒力轉變為驅動機器的有用轉矩，在曲軸前面使用一個液式減震器以減少可能破壞卡特彼勒柴油機的扭轉振動(曲軸上的扭轉)。

Caterpillar CAT diesel engine crankshaft the combustion cylinder into useful torque drive machine, using a hydraulic shock absorber in front of the crankshaft to reduce torsional vibration may damage the Caterpillar diesel engine (torsion shaft).

曲軸是對稱的，這樣可以在當需要卡特彼勒柴油機反向轉動時反轉曲軸。

The crankshaft is symmetrical, so when the need to Caterpillar diesel engine crankshaft and reverse rotation inversion.

曲軸驅動卡特彼勒柴油機前端和后端的齒輪組，卡特彼勒柴油機前端的齒輪組驅動水泵、滑油泵、燃油輸送泵、調整器和兩個輔助裝置，卡特彼勒柴油機尾部齒輪組驅動凸輪軸。

Gear drive Caterpillar diesel engine crankshaft front-end and back-end, front-end gear group Caterpillar diesel engine driven pump, lubricating oil pump, fuel pump, regulator and two auxiliary device, Caterpillar diesel tail gear driven camshaft.

在曲軸兩端，為容易交換和減少保養成本，使用唇邊密封圈和磨套。壓力油通過缸體腹板的鉆孔道供入到所有的主軸承，然后，滑油流經曲軸鉆孔將油供入連桿軸承，卡特彼勒CAT柴油發動機3508卡特彼勒柴油機用五個主軸承固定曲軸，卡特彼勒CAT柴油發動機3512用七個，3516用九個，在中心主軸承兩邊的推力板控制曲軸的端上位移。

In both ends of crankshaft, easy to exchange and reduce maintenance costs, the use of lip seal ring and a grinding sleeve. The pressure oil cylinder through drilling road web fed into the main bearing, all then, oil flows through the crankshaft hole supply of oil into the connecting rod bearing, five main bearing crankshaft for CAT diesel engine was fixed Caterpillar 3508 Caterpillar diesel engine, CAT diesel engine with Caterpillar 3512 seven, 3516 nine, the displacement of the thrust plate center main bearing on both sides of the crankshaft end control.

卡特彼勒柴油機每邊都在一根凸輪軸或凸輪軸組，在卡特彼勒柴油機尾部驅動，3508卡特彼勒柴油機有五個軸承支承每根凸輪軸或凸輪軸組，卡特彼勒CAT柴油發動機3512型有七個，3516型有九個?？ㄌ乇死誄AT柴油發動機3512型和3516型每一種在卡特彼勒柴油機每邊都用二根凸輪軸，用銷釘接在一起和用螺栓接在一起以形成凸輪軸組。當凸輪軸轉動時，每個凸角轉動一個升桿機構，每個氣缸有3個升桿機構，，外面每個升桿機構移動一個推桿和兩個伐(進氣門或排氣門)，中心升桿機構移動一個推桿操作噴油器。凸輪軸必須與曲軸時間相符，凸輪凸角相對于曲軸位置要使每缸的氣門和噴油器在準確的時間動作。

Caterpillar diesel every edge in a camshaft and camshaft group, drive in the rear Caterpillar diesel engine, 3508 Caterpillar diesel engine with five bearing support each camshaft and camshaft group, Caterpillar CAT diesel engine type 3512 seven, 3516 nine. Caterpillar CAT diesel engine type 3512 and type 3516 each in each side of Caterpillar diesel engine with the two cam shaft, pin connected together and bolted together to form a cam shaft group. As the camshaft rotates, each lobe rotate an elevating mechanism, each cylinder has 3 litres of rod mechanism, the outside of each lift rod moving mechanism, a push rod and a two cutting (intake or exhaust valve), center lift rod mechanism to move a push operation injector. The camshaft must be consistent with the crankshaft, cam lobe relative to the crankshaft position to make the valve and injector per cylinder at the exact time action.
