Abstract

PURPOSE: To cool a bearing case sufficiently and promote the explosion-proof capacity by perforating small holes on the bulkhead of an inner air passage in the bearing case and conducting cooling air to a support part.
CONSTITUTION: A part of cooling air is circulated through an inner and an outer passage 4 and 5, and the second part is introduced into a cavity 15 from a labyrinth packing 3 for cooling work. Besides, in this cooling structure, the third part of cooling air is introduced into the cavity 15 through small holes 17 from the inner air passage 4, and dashed to diaphragm 18 to flow into gaps 19, At this stage, the air is mixed with lubricant, and discharged from a discharge pipe together with the lubricating oil to be exhausted to the open air in an oil tank. In this process, since the air jetted out through small holes 17 takes off heat from around small holes 17 and also from the diaphragm 18 as dashing to the diaphragm 18, the temperature in the bearing case 1 can be effectively reduced.
