一立式水轮发电机的轴承立式水轮发电机的轴承(如图1所示),是推力轴瓦支撑着几十吨乃至上百吨的水轮发电机组的转功部分旋转,它的荷重是很大的,需要良好的润滑条件和足够的散热能力,将其旋转中产生的热量带走。一般是用一个油槽盛有足够数量的透平油,将推力瓦浸泡起来,以达到润滑和散热的目的。这样,油槽内既有转动的主轴穿过,又有将转动部分重量传递给基础固定部分的构件,这就决定了油槽止油筒的结构形式,同时上口油面是敞开的(见图1)。
A vertical hydro-generator bearing vertical hydro-generator bearings (shown in Figure 1), is the thrust bearing support dozens of tons and even hundreds of tons of hydroelectric power generating unit rotating part of its rotation The load is great, requires good lubrication conditions and sufficient cooling capacity, the heat generated in its rotation away. Generally use a tank filled with a sufficient amount of turbine oil, soak the thrust pad, in order to achieve the purpose of lubrication and cooling. In this way, both the rotating spindle in the oil tank passes through and there is also a component which transfers the weight of the rotating portion to the base fixing portion, which determines the configuration of the oil sump, and the upper oil level is open (see Fig. 1 ).
