缸体

The structure,property and machinability of materials of sedan-car engine block was tested and studied.

对轿车发动机缸体的材质和加工性进行了实验研究。

This new radial piston pump uses many independent shakeable cylinder blocks besides mechanical mandatory return stroke.

该种新型阀配流式径向活塞泵采用了独立、可摆动式液缸体结构，并利用了机械强制回程。

Secondly, some are weaker in the cylinder block as middle part of the top wall of combustion chamber, the two clipping arm, the side walls for the left and right of pre-compress room etc., and need strengthening. While, there is some sealing questions for cambered surface of both ends of the centre swing.

其次，在结构上发现缸体左右两个卡臂、预压缩室左右两个侧壁及燃烧室上壁中间部分比较薄弱，需要加强；对于中心摆则是两端弧面的密封有些问题。

The experiment shows the temperature rising of the cylinder body is less than 8 digresses Celsius when running at 6500RPM; this can further lower the cost since no cooler is needed.

JAL636-PL经实际测试，在6500RPM最高转速下缸体的温升保持在8℃以内，能完全解决油压回转缸热温升的棘手问题，并且能节省昂贵的油冷却设备成本。

This design makes the engine block and crankshaft shorter and more rigid.

这种设计使得缸体和曲轴更短，刚性也更好。

The assembly of journal and plain bearing liner space is too little, force of organic still oil pressure is small it is the crucial index that affects lubricant result, make lubricate because of lacking engine oil between crankshaft and plain bearing liner and bite dead invalidation, include to be pulled badly, lack lube, layer of alloy of dry attrition generation is fused, grind sliding surface to did not maintain the oily film of certain ply, and all sorts of local overload exhaustion are destroyed, cavitation erosion and V form are destroyed etc, through technology of him director diesel locomotive old experience reachs the analysis of pair of its breakdown reasons, put forward precautionary measures especially. As a result of,the burns caustic mechanism plain bearing liner to burn caustic mechanism of 1 plain bearing liner is the lube film burst between journal and plain bearing liner, cause plain bearing liner and crankshaft generation clash, below high temperature, high pressure and high rotate speed, the wear-resisting alloy layer of plain bearing liner wears away prematurely or fuse, cause plain bearing liner and crankshaft to stick thereby bite, can make the steel back of plain bearing liner and Kong Zhong produces whirligig, inlet port is jammed, carry on the back by steel again with the friction of aperture causes high temperature to make plain bearing liner burned-out further, can cause bolt to break off, happen swing a malign accident that pounds cylinder body of bad internal-combustion engine.

轴颈和轴瓦的装配间隙太小，还有机油压力低是影响润滑效果的关键指标，使得曲轴和轴瓦之间因缺少机油润滑而咬死失效，包括严重拉伤，缺少润滑油，干摩擦产生合金层熔化，磨滑面没有保持一定厚度的油膜，以及各种局部过载疲惫破坏，气蚀和V形破坏等，通过本人主管内燃机车技术多年经验及对其故障原因的分析，特提出预防办法。1轴瓦的烧损机理轴瓦烧损的机理是由于轴颈和轴瓦之间的润滑油膜破裂，导致轴瓦和曲轴产生摩擦，在高温、高压和高转速下，轴瓦的耐磨合金层过早地磨损或熔化，从而引起轴瓦和曲轴粘咬，会使轴瓦的钢背和座孔中产生旋转运动，进油孔被堵塞，再由钢背和座孔的磨擦进一步引起高温使轴瓦烧坏，并会造成螺栓折断，发生甩出捣坏内燃机缸体的恶性事故。

Special allocation of the most advanced Block Bearing boring machine, professional restoration of the main cylinder for the Bush-injury, deformation and Care of the ultra-poor defects, and in accordance with the need for users boring with Bush.

特配置了最先进的缸体轴瓦镗床，专业修复汽缸体主轴瓦承孔损伤，变形，同心度超差等缺陷，并根据需要可为用户镗配轴瓦。

Hydraulic pressure part consists of cylinder body around having some axial direction cylinders, pole piston, matching stream canister and timing equipment. Pyramidal difference decelerate part is composed of twin inner bevel wheel with difference of 2-toothes, twin outer bevel wheel without tooth difference and skew shaft etc.

液压驱动部分由周围均布有若干轴向缸的缸体、柱塞、配流筒及调速装置等组成，减速部分由二齿差内锥齿轮副和零齿差外锥齿轮周向限制副及歪轴等组成。
