摘要
Abstract
Experimental studies are carried out to reveal the relationship between friction characteristics of water lubricated rubber bearings and bearing dimensions. First of all, the friction characteristics of two types of water lubricated bearings are tested by bearing friction test benches. Then, their friction characteristics are modeled and compared, and the water film stiffness of the water lubricated rubber bearings is measured. The effect of rotational speed on water film stiffness is discussed. Results show that experimental data of small size bearings can be extended to originally large size bearings, friction coefficient increases with the increasing of bearing size. Rotational speed has little effect on water film stiffness of the bearing. The dynamic stiffness of the water film is much higher than the series stiffness of the principal shaft and the rubber bearings.关键词
