摘要
Abstract
The rotor system for scroll compressor is researched. The bearing is simulated with"Bushing Joint". The rigid-flexible coupling model of scroll compressor for rotor system with bearing stiffness,and the flexility of small shaft and orbiting scroll is es-tablished. And the rigid-flexible coupling dynamical analysis is conducted. The joint force of the actual and ideal state,the stress and deformation of the small shaft and orbiting scroll under the actual state were obtained. With the ideal state,the roller bearing is not charged with capsizal moment of orbiting scroll. Three pairs of 7001 bearing are charged with capsizal moment. Capsizal mo-ment leads axial air force distributing asymmetrically,and the second 7001 bearing supports great force. The strength and stiffness of small the small shaft and orbiting scroll accord with design requirement. The analysis results will provide theoretical guidance for design and optimization of the scroll compressor.关键词
