Abstract

PURPOSE: To disuse air pipes and reduce costs for production and mainteneance by providing a fan rotating with a shaft between external penetration labyrinth parts and send air into the inside of a bearing part.
CONSTITUTION: A partition plate 23 is provided to connect a labyrinth 12 with an upper lid 4, while a fan 25 is fixed on a shaft 8 to be positioned in an air chamber 24 shaped by the upper lid 4 and the partition plate 23 and to send the air into the inside of a bearing. When the shaft 8 is rotated, the pressure in a part of the air chamber 24 on the side of a labyrinth 11 is balanced with or raised higher than the pressure in an oil tank 5, and the mist or vapor of lubrication oil is prevented from leaking. This construction permits to disuse air pipes and reduce costs for production and mainteneance.
