Blade structure of air conditioner compressor

Technical Field

The utility model relates to a vehicle air conditioner compressor spare part technical field specifically is an air condition compressor blade structure.

Background

The blade in the rotary vane compressor of the automobile air conditioner is one of key parts of the compressor, plays roles of sealing and acting, is closely related to the performance and the noise of the compressor, and is a part with the most complex stress and the worst working environment in the compressor. The structure of the contact surface of the blade head and the cylinder body in the prior compressor is mostly formed by a common circular arc, and the blade head and the cylinder body contact to form a sharp point contact when in contact motion due to the simple shape, so that a great stress is formed, the transition property with the cylinder body molded line is poor, the motion resistance is large, the blade head is quickly abraded, the service life is short, and the whole power consumption and the noise of the compressor are large.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, the utility model provides an air condition compressor blade structure can effectual reduction compressor whole consumption and noise, reduces the head wearing and tearing, improves blade life.

A blade structure of air condition compressor, including the blade body, the blade body includes the head, is located the left end face and the right-hand member face at head both ends, the head has an arcwall face, and blade left end face and right-hand member face are connected to the arcwall face, the arcwall face adopts eccentric design, and the radius R center and the right-hand member face eccentricity of arcwall face are established to X, make the blade head form by low-height-low arc contact surface of transiting gradually.

Furthermore, a surface-to-surface contact is formed between the blade head and the compressor cylinder body, a low pressure oil membrane area is formed between the low arc-shaped contact surface of the blade head and the compressor cylinder body, and a high pressure oil membrane area is formed between the high arc-shaped contact surface and the compressor cylinder body.

The utility model has the advantages that:

1. the abrasion of the blades is reduced, and the service life of the blades is prolonged;

2. the blade operation noise is reduced;

3. the motion resistance of the blade is reduced, the friction is reduced, and the power consumption is reduced;

4. the structure is suitable for the rotary vane compressor with each displacement.

Detailed Description

The embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the blade structure of the air-conditioning compressor includes a blade body 3, the blade body 3 includes a head 301, and a left end face 302 and a right end face 303 located at two ends of the head 301, the head 301 has an arc face 304, the arc face 304 connects the left end face 302 and the right end face 303 of the blade, in order to form the arc face 304 of the blade, the position of the center of the circle of the arc face R obtained by the dynamic calculation is an eccentric center, the eccentric distance between the center of the radius R of the arc face 304 and the right end face 303 is set as X, and the center of the circle is used as the center, the left end face 302 and the right end face 303 of the blade are connected, so that the blade head 301 forms an arc contact surface.

In this embodiment, when the blade moves along with the rotor, because of the special shape of the head arc-shaped surface 304, the surface-to-surface contact state with a certain width can be kept at each position of the cylinder body 1, the great stress and noise caused by the contact of the tip of the head 301 with the cylinder body 1 are eliminated, the abrasion of the blade head arc-shaped surface 304 is reduced, meanwhile, the blade head 301 forms a lubricating oil film area in two areas with different heights, a low-pressure oil film area 4 is formed between the low-arc-shaped contact surface and the compressor cylinder body, and a high-pressure oil film area 5 is formed between the high-arc-shaped contact surface and the compressor cylinder body, so that the lubricating effect of the blade in the working process is ensured.

During operation of the compressor, the vane body 3 rotates clockwise towards the right end face 303 of the vane, and the arc-shaped face 304 of the vane is in low-high-low transition, so that under the action of centrifugal force and backpressure, face-to-face contact with a certain width can be kept on the cylinder body molded line 6 constantly, thereby eliminating great stress and noise caused by contact between the tip point of the head 301 and the cylinder body 1, increasing contact stability and reducing abrasion of the arc-shaped face 304 of the vane. Meanwhile, due to the special shape of the blade arc-shaped surface 304, the blade arc-shaped surface has good transitivity with the cylinder body molded line 6, good fitting performance and compensation performance after abrasion, the effects of reducing the frictional resistance between the blade arc-shaped surface 304 and the cylinder body molded line 6, improving the sealing performance and the service life, reducing the power consumption and the noise can be achieved, and the low-pressure oil film area 4 and the high-pressure oil film area 5 can be formed in two areas with different heights, so that the effects of oil storage lubrication and friction reduction and noise reduction are achieved. In combination with the above, the shape and function of the arc-shaped surface 304 of the vane can effectively reduce the noise of the compressor and improve the performance and reliability of the compressor.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
