今天来看汽轮机推力轴承,以常规300MW汽轮机推力轴承为例。
thrust bearing 推力轴承
thrust pad 推力瓦块
bearing shell 轴承壳体
pad carrier 持环
shim for adjustment/ adjusting pad调整垫片
positioning key 定位键
positioning screw 定位螺钉
sphere pad/ spherical pad / spherical piece 球面垫块
equalized pad 均压垫块
oil sealing ring 油封环
From this picture,we can know how the thrust bearing is fixed with front bearing pedestal.
从这张图可知,推力轴承是如何定位在前轴承座中的。
The axial position of shafting is located by a thrust bearing, and the position of thrust bearing is the anchor point of shafting.
轴系由一只推力轴承轴向定位,推力轴承为整个机组轴系的“死点”。
汽轮机中有些术语在英文中往往不止一种表达形式,如汽缸cylinder/casing,轴承座bearingpedestal/housing/box。
以上是我们的常规的300MW/600MW机组的推力轴承,下面来看下超超临界机组径向推力联合轴承吧~(双面的哦,下面也是一圈推力瓦,两面都是工作面~)
combined journal and thrust bearing 径向推力联合轴承
常用的轴承参数:
Thrust bearing clearence 推力轴承间隙
Bearing vibration 瓦振
Bearing temperature 瓦温
Bearing top clearance 轴承顶隙
Bearing contact area ratio 轴承接触面占比
