Research on Functional Integration Principle and Feasible Region of Magnetic Balancing Disc Thrust Bearing

摘要

An idea of controlling or restricting axial movement of the rotor system using magnetic force was proposed in this paper. A device named Magnetic Balancing Disc (MBD) was developed which could play a role better than general fluid balance disc in certain compressor. Basis principle of magnetic balancing disc was introduced including basic structure of physical integration and feasibility of balancing point. Discussion of functional integration principle based on the design point of view was presented including three design patterns of rotor system, mathematical expressions for design and graphic method. Feasible region analysis based on the balancing point was proposed including working point design under ideal conditions and feasible region assessment under service state.
