磁力推力轴承应力消除

Stress relief in a magnetic thrust bearing
摘要：
Undesirably high stresses are minimized in a magnetic thrust bearing (15) having a disc (52) mounted on a shaft (54). The disc (52) is flanked on both sides (60,62) by respective armatures (68,70) which act to apply a magnetic field to the disc (52) to locate the same at a desired location along the axis (66) of the rotor (14) of the machine in which the thrust bearing (15) is employed. A peripheral, radially outwardly opening, annular groove (76) is disposed in the outer periphery (64) of the thrust bearing disc (52) to relieve stresses during operation.
摘要（中）：

在具有安装在轴（54）上的盘（52）的磁性推力轴承（15）中，使不希望的高应力最小化。 盘（52）两侧上（60,62）由相应的电枢（68,70），其作用是将磁场施加到盘（52）定位在相同沿轴线的所需位置（66） 其中使用推力轴承（15）的机器的转子（14）。 在推力轴承盘（52）的外周（64）中设置周边径向向外开口的环形槽（76），以在操作期间减轻应力。
