Timing gears
The drive gear assembly consists of cylindrical gears with helically cut teeth.
The injection pump and camshaft are driven by the crankshaft via an intermediate gear. The engine’s lubricating oil pump is also driven by the crankshaft via an intermediate drive gear.
Apart from the camshaft, the camshaft gear also drives the sea-water pump drive gear (marine engines), as well as air compressor, if fitted (optional equipment) is also driven by the camshaft gear.
Crank mechanism
Crankshaft
The crankshaft is journaled in seven main bearings. The axial bearing consists of thrust washers located at the centre main bearing. The crankshaft is balanced both statically and dynamically. The front end of the crankshaft has a polygon profile and the rear end has a flange to which the flywheel is bolted.
The crankshaft is nitro-carbureted. Provided that the shaft does not need to be straightened before grinding, grinding to max. 2nd undersize can be done without a renewed nitro-carburetion
这种总成由驱动齿轮与形的圆柱齿轮切齿。
注射泵和凸轮轴的驱使下,透过曲轴一个中间齿轮。发动机的润滑油泵曲轴驱动通过一种中间驱动齿轮。
除了凸轮轴,凸轮轴齿轮也开车的海水液压泵驱动齿轮(船用柴油机的),以及空气压缩机,如果装上(可选设备)也驱使凸轮轴齿轮。
曲柄机构
曲轴
曲轴是journaled在七个主要轴承。轴轴承由止推垫片位于中心主要轴承。曲轴是静态与动态平衡两者。曲轴的前端有一个多边形轮廓线和尾部有一个法兰,飞轮螺栓。
曲轴是nitro-carbureted。只要这样的轴不需要弄直在磨粉之前,麦克斯。第2减少磨削可以做没有更新
