Tóm tắt

We present the experimental results of studying the pressure fields in the hydraulic duct and throttling characteristics in the radial double-center reversing plain bearing having a chamber and a recess made on its working surface. It is established that the zones of lubricating film rupture appear in the bearing elements when there exist eccentricity and shaft rotation.
