一、轴瓦与轴颈配合不当易烧瓦当轴瓦与轴颈配合间隙过小时，润滑油不易进入轴瓦，轴瓦与轴相互摩擦，产生过高的温度，导致热量不易散掉而烧瓦。当轴瓦与轴颈配合间隙过大时，使得曲轴的转动难以产生油膜，于是，轴瓦与轴颈发生撞击，轴瓦被挤压变形而烧瓦。对于这类问题...

First, the bush and journal with improper easy to burn When the bush and journal with the gap is too small, the lubricating oil is not easy to enter the bearing, bush and shaft friction with each other, resulting in excessive temperature, resulting in heat is not easy to dissipate and bush. When the bearing bush and journal with the gap is too large, making the crankshaft rotation is difficult to produce oil film, so the bearing bush and journal impact, bearing bush is crushed and deformed. For such problems ...
