FIELD: electrical and radio engineering; explosion-tight electrical machines.
SUBSTANCE: movable members forming explosion-tight clearances with electrical-machine shaft as well as with butt-end surfaces engageable with these members and bearing housing wall are made in the form of flat rings and extreme flat ring or bushing and extreme flat ring. Explosion protection is ensured by explosion-tight clearance between flat rings or bushing and electrical-machine shaft as well as by means of explosion-tight clearance between flat rings or bushing and extreme flat ring.
EFFECT: simplified mechanical design, enhanced service life, reduced manufacturing cost and maintenance charges.
