発明は上述した点に鑑みて創案されたもので、その目的
とするところは、このような軸受の寿命に悪影響を与え
ない全閉型回転機を提供することにある。However, in the conventional configuration, heat on the inner diameter side of the bearing cannot be dissipated, and as a result, the temperature of the entire bearing is increased. As a result, the life of the bearing is adversely affected, and the replacement period of the bearing is shortened. The present invention has been made in view of the above points, and an object of the present invention is to provide a fully-closed rotating machine that does not adversely affect the life of such a bearing.
