Theoretical Study of the Static and Dynamic Characteristics of a Slotted Adaptive Hydrostatic Thrust Bearing with a Regulator of the Lubricant Output Flow

This manuscript considers the design of a slotted adaptive hydrostatic thrust bearing with regulator lubricant output flow. A theoretical study its static and dynamic characteristics was carried out. The aim to test reliability hypothesis concerning possibility obtaining stable-to-oscillation negative compliance, avoiding need for complex system external combined throttling by replacing it simple throttle. Mathematical modeling movement reducing compliance values is shown, providing an function, consisting using structure as active deformation compensator elastic metal-cutting machine in order improve quality metalwork. Analysis load showed that provided over wide range loads, which can be up 75% or more permissible loads. Based on characteristics, concluded targeted selection parameters have major effect dynamics structure, considered attain very high dynamics. It shown viscous damping lubricating film enclosed gaps material ring are important resources ensuring optimal bearing.
