卡特彼勒CAT柴油发动机曲轴修理技术

Caterpillar CAT diesel engine crankshaft repair technology

卡特彼勒CAT柴油发动机曲轴使气缸内的燃烧力转变为驱动机器的有用转矩，在曲轴前面使用一个液式减震器以减少可能破坏卡特彼勒柴油机的扭转振动(曲轴上的扭转)。

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).

曲轴是对称的，这样可以在当需要卡特彼勒柴油机反向转动时反转曲轴。

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

曲轴驱动卡特彼勒柴油机前端和后端的齿轮组，卡特彼勒柴油机前端的齿轮组驱动水泵、滑油泵、燃油输送泵、调整器和两个辅助装置，卡特彼勒柴油机尾部齿轮组驱动凸轮轴。

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.

在曲轴两端，为容易交换和减少保养成本，使用唇边密封圈和磨套。压力油通过缸体腹板的钻孔道供入到所有的主轴承，然后，滑油流经曲轴钻孔将油供入连杆轴承，卡特彼勒CAT柴油发动机3508卡特彼勒柴油机用五个主轴承固定曲轴，卡特彼勒CAT柴油发动机3512用七个，3516用九个，在中心主轴承两边的推力板控制曲轴的端上位移。

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CAT柴油发动机凸轮轴

卡特彼勒柴油机每边都在一根凸轮轴或凸轮轴组，在卡特彼勒柴油机尾部驱动，3508卡特彼勒柴油机有五个轴承支承每根凸轮轴或凸轮轴组，卡特彼勒CAT柴油发动机3512型有七个，3516型有九个。卡特彼勒CAT柴油发动机3512型和3516型每一种在卡特彼勒柴油机每边都用二根凸轮轴，用销钉接在一起和用螺栓接在一起以形成凸轮轴组。当凸轮轴转动时，每个凸角转动一个升杆机构，每个气缸有3个升杆机构，，外面每个升杆机构移动一个推杆和两个伐(进气门或排气门)，中心升杆机构移动一个推杆操作喷油器。凸轮轴必须与曲轴时间相符，凸轮凸角相对于曲轴位置要使每缸的气门和喷油器在准确的时间动作。

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.
