PURPOSE:To improve the lubrication and cooling of a roller bearing by providing oil supply and exhaust ports communicating with a roller at a roller bearing retaining box and flowing lubricating oil into the bearing. CONSTITUTION:Oil supply and exhaust ports 3c, 3d which communicate with a roller 2b are formed at a roller bearing retaining box 5a to flow lubricating oil into a roller bearing 2. Thus, the oil is flowed into the bearing 2, thereby improving the lubrication and cooling of the bearing 2 even in a high speed large capacity machine of withstand pressure and explosionproof structure. |
