Non-Contacting Fluid Ring Seal Systems for Railcar Axle Bearing Systems: Fifth Quarterly Report, June 16, 1988-September 15, 1988.

摘要

During this fifth quarter the evaluation of D-size fluid ring sealed roller bearing assemblies was completed with the evaluation of seal configuration MT 3008 and 3016, 3016a and 3016b (different static contact seal concepts), when exposed to intensive dust and rain storms generated within an enclosure surrounding the nondriven side of test rig /number sign/3 over the entire speed range from 0 to 1220 RPM bearing test speed. During the test rig /number sign/3 shake down test runs it became apparent that the intensity of the dust and rain storms surrounding the fluid ring sealed bearing end within the ''mini'' climate chamber could be appropriately observed through small windows at 12:00 and 6:00 o'clock provided in the endwall of the ''mini-climate'' chamber, rig /number sign/3 was accordingly modified and the dust and rain exposure tests were conducted at numerous levels of severity. 6 figs.
