METHOD OF PROTECTION OF AIR PASSAGE IN JOINT OF MOVABLE PARTS OPERATING IN UNSAFE ENVIRONMENT, JOINT USED TO IMPLEMENT THIS METHOD AND ROTARY LINE WITH SUCH JOINTS

摘要

FIELD: machine building.SUBSTANCE: straight-toothed cylindrical engagement between rotors of the movable parts of the turbine machine contains two toothed rims. Each toothed rim is located at end of the movable part and is in engagement with another toothed rim providing free passage for air between throats of the surrounding parts, and ends of the surrounding parts of teeth. The toothed rim of at least one movable part continues in radial direction relatively to another toothed rim to form external or internal extension of the toothed rim against the element surrounded by the movable part or surrounding the movable part installed on another toothed rim. To protect the air passage in joint between the rotors of the movable parts one end of the joint is continued in radial direction relatively to the another end to form the external or internal expansion. The expansion is made against the element surrounded by the movable part or surrounding the movable part installed at another end of the joint. This invention of the group relates to the rotor line of the turbine machine containing multiple specified above straight-toothed cylindrical engagements between the rotors of compressors and turbines.EFFECT: group of inventions excludes closing of air passage in joint between rotors of the turbine machine.9 cl, 9 dwg
