где W1 - ширина взрывонепроницаемой плоской щели между подшипниковой крышкой и втулкой;
W2 - ширина взрывонепроницаемой плоской щели между втулкой и подшипниковой крышкой;
ширина взрывонепроницаемой диаметральной щели между подшипниковой крышкой и втулкой;
ширина взрывонепроницаемой диаметральной щели между втулкой и валом;
L1 - длина взрывонепроницаемой диаметральной щели между подшипниковой крышкой и втулкой;
L2 - длина взрывонепроницаемой диаметральной щели между втулкой и валом.Explosion-proof bearing assembly of an electric machine with horizontal or vertical shaft arrangement, comprising a rolling bearing mounted on the shaft, a bearing cap, in the annular groove of which is a sleeve having freedom of axial and radial movement and forming explosion-proof diametrical slots with a bearing cap, sleeve and shaft, characterized in that the length of the flameproof diametrical gap between the bearing cap and the sleeve is less than the length of the flameproof diameter the gap between the sleeve and the shaft, the end surfaces of the annular groove of the bearing cover and the sleeve form additional flameproof flat slots, the total maximum value of which when the sleeve is displaced all the way to the end of the ring groove is at least equal to the total value of the flameproof diametrical slots between the annular groove of the bearing cover and sleeve, sleeve and shaft - and the width and length of the flameproof gaps between the bearing cover and the sleeve, the sleeve and the shaft are related by the ratio
where W 1 - the width of the flameproof flat gap between the bearing cover and the sleeve;
W 2 - the width of the flameproof flat gap between the sleeve and the bearing cover;
the width of the flameproof diametrical gap between the bearing cover and the sleeve;
the width of the flameproof diametrical gap between the sleeve and the shaft;
L 1 - the length of the flameproof diametrical gap between the bearing cover and the sleeve;
L 2 - the length of the flameproof diametrical gap between the sleeve and the shaft.
