METHOD FOR TIGHTNESS ASSEMBLING OF PARTS |
摘要 |
FIELD: processes and apparatuses for assembling parts at tightness, possibly production and restoration of sleeves of sealing unit of turbo-compressor. ^ SUBSTANCE: method comprises steps of placing sleeve into embracing part at technological tightness; performing electric-contact heating of inner surface of sleeve and then deforming it by drifting for creating mounting tightness of sleeve and embracing part joint; smoothing roughness of inner surface of sleeve. Electric-contact heating and drifting of inner surface of sleeve are realized with use of duplex tool in the form of contact- heating tool and arranged behind it deforming- calibrating tool. Contact-heating tool provides heating of inner surface of sleeve in annular zone of contact with said contact-heating tool. Deforming- calibrating tool is mounted at tightness equal to 0.8 mm. In the result during one operation sleeve is pressed-in to embracing part, roughness of inner surface of sleeve is smoothed and inner surface of sleeve is strengthened at hardness 48 - 54 HRC3. ^ EFFECT: enhanced efficiency of assembling parts. |
