一、拉缸的原因 1.左右方向拉缸的主要原因 (1)由于活塞销孔、铜套的铰削加工及销的选配不当,造成装配过紧,使活塞变形,垂直于活塞销轴线方向的直径增大,因而该方向活塞裙部与缸壁间的间隙变小,活塞受热后卡死在气缸内。 (2)气缸镗磨及活塞选配不当,形成配合间隙过小,工作中活塞受热卡死在气缸内。 (3)气缸套中轴线在连杆摆动方
First, the reasons for pulling the cylinder 1. The main reason for pulling the cylinder left and right (1) due to the piston pin hole, copper sleeve reaming and dowel mismatch, resulting in tight assembly, the piston deformation, perpendicular to the piston pin axis The diameter of the direction increases, so the direction of the piston skirt and the gap between the cylinder wall becomes smaller, the piston stuck in the cylinder after heating. (2) cylinder bore and piston improper selection, the formation of small gap with the work of the piston stuck in the cylinder died in the cylinder. (3) cylinder sleeve axis in the connecting rod swing side
