An inspection is completed on pistons and connecting rods and a report on the feasibility of repair is given to the supervisor 活塞连杆曲轴的检验报告已经出据，并维修的可行性报告已交付给相关的监督人员。
The throw of the crankshaft , i . e . the distance between the main journal and the big end centers , controls the length of the stroke 曲轴的摆幅，即在主要曲颈和连杆大头末端中心之间的距离，控制着冲程的行程。
Stiffness will decrease because of crack . the stiffness of crankshaft is changing due to open - close of crack under alternating load of crankshaft 裂纹导致曲轴的扭转刚度下降，裂纹的张开和闭合导致扭转刚度在一个工作循环中是变化的。
At the rear end of the crankshaft is attached the flywheel , and at the front end are the driving wheels for the timing gears , fan , cooling water and alternator 曲轴的后端连接着飞轮，前端是连接着定时齿轮，风扇，冷却水和交流发电机的驱动轮。
Several years , we instst scientific developing strategies , widly admit talents , trying our best to develope low - voicebent - axis and we re gained dependable effects 几年来，我公司坚持科技振兴的战略，光招贤才，致力于低噪音曲轴的攻关新产品开发，取得可靠的成效。
Meanwhile , the fracture was accelerated due to the uneven surface hardness and the unreasonable distribution of the hardening layer on the crankshaft , and the bad lubrication condition in service 同时轴左颈表面硬度不均匀、淬硬层分布不甚合理，工作过程中润滑条件差，加速了曲轴的断裂。
The dynamic response of crankshaft stress and displacement and so on is analyzed by dynamics simulation , and the consequence results can be referenced for design and dynamic fatigue analysis of crankshaft 通过动力学仿真分析曲轴的应力和位移等动力响应，为曲轴的动态疲劳分析提供依据，为曲轴设计提供参考。
In this paper , the bend stress of engine crankshaft was analyzed by the finite element method ( fem ) . an one - fouth crankthrow fe model is used to analyze it taking different boundary conditions into account 本文用有限元法计算分析了发动机曲轴的弯曲应力。采用1 4曲拐有限元模型对不同边界条件进行了研究，计算了安全系数。
In the project of mechanical structure , we bat around the error and metrical way of crank shaft , describe the elements of the synthetically measure instrument of crank shaft and the way to realize it 在机械部分中，我们对曲轴的公差要求以及各项公差测量的方法进行了详细的分析，讲述了整个量仪设备的工作原理、工作过程以及机械设计的实现方案。
The bore at the positions shown in fig 2 of appendix 1 shall be measured to 1 / 1000mm in unit in the crankshaft direction and right - angle direction , and the bore shall be expressed by the average of these values 对于位于附录1的图2中所示位置的孔，要在部件上按照曲轴方向以及（垂直于曲轴的）直角方向进行测量，达到1 / 1000毫米的精度，并且用这些值的平均值来表示孔径。
