Research of the Scroll Expander with Variable Base Circle Radius Involute
摘要
Abstract
Theprofileequationandtheexpandedvolumeofthescrollexpanderwithvariablebasecircleradiusinvoluteisstud-ied.Based on the normal operational principle the scroll expander,this paper firstly deduces the necessary condition of variable base circle radius involute profile to constitute the scroll expander,furthermore,obtains the profile equation of the base circle invo-lute with varing radius.According to the profile equation,the coordinate equations of the inside and outside walls for the moving and fixed scrolls are obtained.According to coordinate equations,the scroll chambers constituted by the variable base circle radius involutes are described.And the geometry feature of the profile of base circle involute with varing radius is analyzed.Finally ac-cording to the volume change regularity of scroll chambers and the mesh point feature,this paper deduces the range of the flare an-gle for each expansion chamber.And using the second expansion chamber as an example,normal equidistant curve method is ap-plied to calculate each chamber volume.It provides a theoretical basis for the further research of the variable base circle radius in-vloute scroll expander.关键词
