1.配瓦之前必须测量曲轴的弯曲度,例如4125型曲轴,其弯曲度不大于0.10毫米时,可以用压床校正。还要测量各道轴颈的椭圆度与锥度。由于条件所限,测量曲轴摆差,可在倒置的缸体进行,也就是说,将一、五道(指四缸发动机)上瓦片放入座内,把曲轴放上,轻轻用手转动,从磁性表头就可看出数据。 2.应刮配好各道主轴瓦的同心度。因为配瓦时缸体是倒置的,当逐步拧好各道主轴瓦座螺母后,应用手
1.With the watts must be measured before the crankshaft bending, such as 4125 crankshaft, the curvature of not more than 0.10 mm, you can use the press correction. Also measure the ellipticality and taper of each shaft journal. Due to limited conditions, measuring crankshaft deviation can be carried out in the inverted cylinder, that is, one or five (referring to the four-cylinder engine) on the tile into the seat, put the crankshaft, gently with your hand Turn, can see the data from the magnetic head. 2. Shaving should be good with all the main bearing concentricity. Because with the tile when the cylinder is inverted, when gradually screw the main bearing bush nut, the application of hand
