На фиг, 1 изображен узел уплотнени вала ротора, разрезj на фиг,2 разрез А-А на фиг.1. - Узел уплоч нени вала ротора сос- 5 тоит из торцового щита 1, на котором закреплен корпус масл ного уплотнени 2 и маслоуловитель 3 с цилиндрической разрезной, с технологическим зазором 4 между ее концами О манжетой 5 из эластичного материала и установленной, с радиальным зазором 6 относительно вала ротора.FIG. 1 shows a rotor shaft sealing assembly, a section j in FIG. 2, section A-A in FIG. 1. - The rotor shaft mounting unit consists of a face shield 1, on which the oil seal housing 2 and oil catch 3 with a cylindrical split, are fixed, with a technological gap 4 between its ends O and an elastic cuff 5 and with a radial clearance 6 relative to the rotor shaft.
При нормальной работе машины манжета нагреваетс и расшир етс 15 в сторону ее свободных концов, сохран при этом радиальный зазор мелсду валом ротора и манжетой оDuring normal operation of the machine, the cuff is heated and expands 15 toward its free ends, while maintaining the radial clearance of the Melsda by the rotor shaft and the cuff.
