内燃机的主轴瓦和连杆轴瓦在安装以后,不仅要防止转动,而且在气体爆发力和惯性力产生的很高的动载荷作用下,保持瓦背与座孔的贴合度大于85％,否则就不能保证运转中的摩擦热很好地经轴承传出,情况严重时会烧坏轴瓦。
After installation, the main bearing and the connecting rod bearing of the internal combustion engine should not only prevent the rotation but also keep the fit of the tile back to the seat hole to be over 85% under the high dynamic load caused by the explosive force of gas and inertial force; otherwise Can not guarantee that the friction heat in operation is well received by the bearing and the bearing bush will be burned when the condition is serious.
