摘要：與缸體內壁相接觸的葉片頭部形狀是旋葉式壓縮機設計的關鍵之一。應用微分幾何理論，研究出與各設計基本參數緊密相關、與缸體型線相匹配的葉片型線設計方法，從理論上保證旋葉式壓縮機的運行可靠性，為實現高效壓縮的旋葉式壓縮機設計提供計算依據，拓寬設計理論。計算機仿真與試驗表明，由設計理論獲得的葉片具有很好的嚙合特性，完全消除了“尖點滑移”和局部磨損現象，具有均勻相對滑動：型線的形狀保證葉片頭部與缸體內壁的運行可靠性;葉片頭部具有z*簡單的型線形狀，易于機械加工制造：與主型線光滑連接的前、后過渡修正圓弧，使葉片與缸體內壁嚙合時，不成刀刃狀，且利于形成油膜，改進潤滑狀況，同時降低缸體、轉子及轉子葉片和葉片槽的加工和裝配精度要求。

Abstract：The vane tip profile contacted with the inner wall of the stator is a key point in designing the rotary vane compressor.Thevane tip profile design，matched with the stator profile，closely connected with the essential parameters is presented with thegeometric theory of calculus ensuring the reliability of the rotary v剮rle compressor.The theoretical calculation basis is provided forthe design of the rotary vane compressor with high efficient compression and the design theory of the rotary vane compressor isbroadened.Computer simulation and test demonstrate that the new vane has a better meshing characteristic，which eliminates thescraping between the vane tip and the cylinder and partial abrasion conditions completely,and leads tO sliding uniformly.The shapeof the vane tip profile ensures the reliability of the seal between the vane tip and the inner wall of the stator;the vane tip profile issimple，and easy tO machine.When the vane is meshed with inner wall of the stator,the front and rear transitional arcs smoothlyconnected with the main vane profile Can not only avoid tO form a cutting edge shape，but also benefit to form oil membrane.The precisionrequirement of manufacture and assembly of stator,rotor,vane and rotor slot is reduced.
