Experimental Research on Film Pressure Distribution of Water-Lubricated Rubber Bearing With Multiaxial Grooves

In order to obtain the entire continuous circumferential film pressure distribution of a water-lubricated rubber bearing with multiaxial grooves, and further to study the bearing properties, an experimental research was conducted. The wireless measurement scheme was proposed, which can make the measurement process simple, convenient, and accurate. The unique design of the shaft and the installation methods for the pressure sensors are described. The time-domain averaging (TDA) algorithm was presented to suppress the random noises of the film pressure signal. By contrastive analysis on experimental results, some bearing properties, and working mechanism have been found and demonstrated.
