A liquid damping system provided in the assembly is formed by a first chamber located on the bearing side of the bearing element and a second chamber located on the opposite side of the bearing element with one or more passages being provided for the damping liquid to flow between the first and the second chamber during displacement of the bearing element, the passage being proportioned relative to the bearing element such that only a relatively small damping force is applied against the bearing element during displacement thereof.Field of SearchHydraulic or pneumatic bearing supportResilient bearing surface Coil spring Biased bearing surface segment Helical coil spring Resilient sleeve Volute coil spring Helical coil spring Fluid damping Lower end thrust bearing For shaped shaft end Spherical shaft end Conical shaft end For vertical shaft With lower thrust and upper radial bearing For vertical shaft For bearing at end of shaft | |
