A Rotary Vane Type Varying Mechanism with Non-equal Angle Engagement

Abstract

The invention discloses a rotary vane type capacity changing mechanism in non-isometric engaging. A middle fixing body, a disk and a periphery rotating part are included; the center axis of the outerwall of the middle fixing body is provided with a machine body, and the middle fixing body is provided with a radial groove; the groove wall of the radial groove is provided with a turning hole, and the position of the center axis of the disk is provided with a rotating hole; the inner wall of the turning hole penetrates through the rotating hole through a screw to be arranged in the radial groove; the disk is installed on the inner wall of the radial groove through a bolt; inclined engaging grooves are arranged on the disk in the radial direction; and the periphery rotating part is located onthe outer wall of the machine body. In the rotary vane type capacity changing mechanism in non-isometric engaging, when the number of rotary vanes is larger than that of the engaging grooves, the capacity changing mechanism can guarantee that fluid acquires the needed axial movement speed under a low rotating speed; and when the number of the rotary vanes is smaller than that of the engaging grooves, under the same axial movement speed, the rotary vanes are more smooth, the component force of the mutual interaction force between the fluid and the rotary vanes is larger in the axial direction,and therefore the loss of the tangential component force is lowered.

Description

technical field [0001] The invention relates to the technical field of fluid displacement, in particular to a non-equal angle meshing rotary vane type displacement mechanism. Background technique [0002] The variable volume mechanism is one of the basic devices that utilize mechanical motion to realize periodic changes in space volume, and has a wide range of applications. According to the characteristics of periodic volume changes, the variable capacity mechanism can be used as a compressor, a vacuum machine, an engine, and various fluid power machines that need to produce directional motion of the fluid. The rotary vane meshing variable displacement mechanism is the main reference document. The blades of this patent are connected to the outer casing instead of the middle, and the outer casing is connected to the middle rotating shaft through a connecting rod. The rotating shaft passes through the middle fixed part, and the middle There is a slot for installing the disc o...
