Abstract
The vane tip profile contacted with the inner wall of the stator is a key point in designing the rotary vane compressor.The vane tip profile design,matched with the stator profile,closely connected with the essential parameters is presented with the geometric theory of calculus ensuring the reliability of the rotary vane compressor.The theoretical calculation basis is provided for the design of the rotary vane compressor with high efficient compression and the design theory of the rotary vane compressor is broadened.Computer simulation and test demonstrate that the new vane has a better meshing characteristic,which eliminates the scraping between the vane tip and the cylinder and partial abrasion conditions completely,and leads to sliding uniformly.The shape of 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 is simple,and easy to machine.When the vane is meshed with inner wall of the stator,the front and rear transitional arcs smoothly connected with the main vane profile can not only avoid to form a cutting edge shape,but also benefit to form oil membrane.The precision requirement of manufacture and assembly of stator,rotor,vane and rotor slot is reduced.
