1常规检查法柴油机大中修时,必须认真检查连杆的变形,并予以校正。对于连杆大小端孔中心线平面内的弯曲,通常是通过测量大小端孔中心线的平行度来检验。检查前,连杆小端衬套必须经过铰孔,大端轴瓦也需通过刮配。检查时,利用一根与连杆大端准确配合的心轴——假轴,将连杆竖直地放在V型铁上(图1),调整V型铁的高度,使心轴与平板平行,然后分别测量活塞销的两端,所得读数的差值对二测点间距离的比值来表示,即
1 routine inspection method Diesel engine repair, you must carefully check the connecting rod deformation, and be corrected. Bending in the plane of the centerline of the connecting rod-size end hole is usually verified by measuring the parallelism of the centerline of the end hole of the size. Before the inspection, the connecting rod small end bushing must pass through the reaming hole and the big end bearing bush also needs to pass the scraping. Check, the use of a connecting rod with the exact end of the mandrel - false axis, the link on the vertical V-shaped iron (Figure 1), adjust the height of the V-shaped iron so that the mandrel and the plate Parallel, and then were measured at both ends of the piston pin, the difference between the readings on the ratio of the distance between the two measuring points that
