3 结构特点 3.1 机体机体构成了柴油机的骨架,在机体上安装着柴油机的所有零部件和附件。为了保证运动件的相对位置准确,并按照一定的规律运转,机体要有一定的强度和刚度。机体还构成了水套,分布着钻通的机油道,这就要求机体具有气密性,铸件不要存在砂眼、缩松和缩孔。在强度和刚度方面,要求机体有一个合理的结构。CY102系列柴油机采用了半隧道式曲轴箱结构,曲轴中心分开面距底面为75mm,缸体和曲轴箱制成一体式,缸体采用干式缸套,同时根据机体的受力状况进行了合理的布筋。合理布筋可减薄机
3 Structural Features 3.1 Body The body constitutes a diesel engine skeleton, the engine is equipped with all the diesel engine parts and accessories. In order to ensure the relative position of the moving parts is accurate and in accordance with certain laws of operation, the body must have a certain degree of strength and rigidity. The body also constitutes a water jacket, distribution of the drilling machine through the oil, which requires the body with airtight, casting does not exist trachoma, shrinkage and shrinkage. In terms of strength and stiffness, the body is required to have a reasonable structure. CY102 series diesel engine uses a semi-tunnel type crankcase structure, the center of the crankshaft is separated from the bottom surface of 75mm, cylinder and crankcase made of one, the cylinder block with a dry, at the same time according to the body’s stress conditions were reasonable Cloth reinforcement. Reasonable fabric can be thinning machine
