摘要
屏蔽电动机轴承采用水润滑轴承,模拟推力轴承运行工况,设计了一套水润滑推力轴承试验装置,并可在一定范围内对轴承承受的轴向力进行调节。电涡流位移传感系统采用美国Bently公司的3300XL8mm移感器系统,通过对台架的推力轴承水膜厚度进行测量,测量到完整的水膜,与理论计算结果进行比较,结果表明在水润滑条件下,能够形成稳定水膜。
A water-lubricated bearing is applied to canned motor. A set of test equipment of water-lubricated thrust bearing for canned motor is designed by modeling operation state of the thrust bearing, and the axial force of bearing can be adjusted in certain range. 3300XL 8mm sensing system of USA Bently Company is adopted to electric eddy current displacement sensing system. The complete water film of thrust bearing for bench can be measured. By comparing with the theoretical calculating result, it is indicated that the stable water film can be formed under water-lubricated condition.
