查询词典 rigging screw

By analysing and calculating the variations in distribution of axis direction contact force and contact pressure on screw thread, the influence of errors of pitch and taper of casing screw threads to the properties of resisting pull and sealing liquid and gas are studied. Based on the result obtained through analysis, a reasonable tolerance distribution for pitch and taper is proposed.
