摘  要：
A traditional transmission system always uses metallic bearings and lubricates by oil. In such a way, many problems may appear, such as unbalanced load, certain friction, wear and tear, vibration noise, wattless consumption and pollution. Water lubricated plastic alloy bearings can solve the problems. However, under a high load, it's difficult to form hydrodynamic lubrication because of a low viscosity of water. So an elastic deformation of water lubricated plastic alloy bearings was analyzed on dynamic pressure, the supported clearance equation was derived and pressure function was expanded by Fourier series. An elastic deformation was deduced by the pressure function. At last a pressure distribution function and an elastic deformation function on dynamic pressure were developed. The functions predict that the bearing power increases because of the elastic deformation. Effect of the elastic deformation becomes evident with higher eccentricity and all the phenomena during working can be explained by the analysis.
