摘要
测定缸壁和活塞配合间隙的大小,对评定气缸活塞零件技术状况至关重要。按苏联标准测取不同的缸套直径时,得出的配合间隙值也各不相同。经试验,确定了测取缸壁和活塞以及活塞裙配合问隙的适当方法。
To measure the clearance between the piston and cylinder wall is very important in evaluating the technical stafe of the cylinder-piston assemblies. According to the standards of USSR,the clearance is different if cylinders with different diameters are chosen to be measured.On the basis of tests,a proper me- thod of measuring the clearance between the piston head and the cylinder wall,and between the piston skirt and the cylinder wall has been found.
