Problems solved by technology

Its disadvantages are: since the profile line of the blade head is a single arc, the meshing between the blade and the inner wall of the stator only slides in a small range behind the arc profile of the blade head, and "cusp slippage" occurs in a larger range. ” phenomenon, and there is a large gap on the front side of the blade head, resulting in high friction power consumption and reduced volumetric efficiency of the rotary vane compressor
After installing and running the traditional blade for 800 hours, a three-coordinate measuring instrument is used to measure the worn head, and a series of coordinates of the measurement points are obtained. These coordinate points are fitted with a circular arc, and the center of the obtained circular arc is not in the At δ / 2 of the blade thickness, since the wear of the traditional blade is concentrated on the rear section of the blade head, the worn head profile is not the actual head profile of production, so this data cannot be used as processing and manufacturing data in actual production. Implemented in manufacturing

The head mould lines of the vanes include the main arc mould line with radius r, the front sect correcting mould line with radius r1 and the back sect correcting mould line r2. one end of the front and the back correcting mould lines and the two ends of the main arc mould line are tangential at the points P2 and P3, the other ends of the two correcting mould lines and the upper ends of the vanes are tangential at the points P4 and P1.

Description

Technical field: [0001] The invention relates to a rotary vane compressor for an automobile air conditioner. Background technique: [0002] The rotary vane compressor introduced in "Rotary Compressor" published by Mechanical Industry Press in 1988 and edited by Deng Dingguo and Shu Pengcheng of Xi'an Jiaotong University. The compressor includes: a stator, a rotor shaft, a blade front end cover and a rear end cover, the rotor shaft is arranged eccentrically in the stator, and the blades are placed in the rotor shaft chute. When the rotating shaft rotates at high speed, under the action of centrifugal force, the blades are thrown out along the chute of the rotor shaft, and their heads contact the inner wall of the stator. The blade design principle is: according to the blade eccentricity circle radius R 2 = 0, the shape line of the blade head is an arc whose center is at the center of the blade, that is, the center of the circle is at δ / 2 of the blade thickness. Its disadva...
