本発明は、蒸気タービンの軸受装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bearing device for a steam turbine.
蒸気タービンに用いられる軸受として、構造が比較的な
簡単である楕円型軸受を第１図に示す。FIG. 1 shows an elliptical bearing, which has a relatively simple structure, as a bearing used in a steam turbine.
こｎは、回転体であるジャーナル１に対して、内径部に

さ扛、ジャーナルに吸引され、排油孔より排出さｎる。This is a journal 1, which is a rotating body, and two upper and lower bearing cases 2a and 2b, each with a babbitt hooked into its inner diameter.
is a structure in which allllllll Kling 3 is fixed,
Lubricating oil is supplied through an oil supply hole provided in the lower bearing case 2b, sucked into the journal, and discharged through an oil drain hole.

） 、 （５） 。On the other hand, the tailing band bearing shown in Fig. 2 is used because it is extremely stable against the load M variation that the bearing receives. In response to the eccentricity of the journal, there is an A adjustment function in the case.
A plurality of tailings 4 are provided. The contact between this tilting and the bearing case is generally point contact or scarlet contact, which has poor heat release.As shown in Figure 3, the lower tailing 4-(4

In the case of (5) and (6), 110 to 120 rK1 due to the carryover effect of oil heating due to journal rotation.
The temperature rises during this process, softening the pavit metal cast into the inner diameter surface of the tail bearing, which may impair the bearing function.
不発・明の目的はかかるテイルテイングパッドの１Ｍ度
上昇を押える冷却機能を有する軸受桝造全提供するもの
である。The object of the present invention is to provide a bearing cage having a cooling function that suppresses the rise in temperature of the tailing pad by 1M degrees.
