Research of Coil Spring for Refrigeration Linear Compressor
2022
Journal of Mechanical Engineering
Abstract:The spring is the key part to realize the resonance control of the piston of the linear compressor and to affect the compressor's life. In order to solve the problems of small stiffness and large number of plate springs used in compressors, a kind of multi-arm Archimedes spiral coil spring is designed. Finite element method is used to analyze the influence of parameters of Archimedes spiral on the stiffness of the spring arm, such as the base circle radius r, the sweep angle slightly θ
