Abstract
The utility model relates to a blade of a rolling rotor compressor. The rolling rotor compressor comprises a housing and a rotor arranged in the inner cavity of the housing, the end surface of the head end of the blade adopts a convex arc surface, the convex arc surface is contacted with the surface of the rotor, and the end surface of the tail end of the blade adopts a curved surface. The end surface of the tail end of the blade adopts a conical surface. The end surface of the tail end of the blade adopts a circular arc surface. The resistance borne during the running process of the blade is reduced through improving the tail end of the blade into the circular arc shape or the conical surface, the lost motion of the blade is reduced through decreasing the smack or agitation to oil during the running process of the blade, the oil leakage of the compressor is also reduced by diminishing the atomization and the splash of the oil in the compressor, and both the efficiency of the compressor and the actual configuration of an air conditioner are improved.
Description
Technical field
The utility model relates to compressor, relates in particular to a kind of blade of rolling rotor type compressor.
Background technique
During compressor operating, the blade of compressor inside continues to move back and forth under spring and back pressure effect; Because general operational requirement lower compression machine oil pond height can be higher than cylinder lower end surface (being the blade lower end surface), therefore, blade is in operation and can bounces fluid.
As shown in Figure 1, in the prior art, the tail end 11 ' of compressor blade 1 ' be shaped as the plane, this structure has caused blade to bounce refrigerator oil making the situation of its atomizing of splashing comparatively serious when high speed operation (particularly), thereby has increased the oil yielding rate of compressor; In addition, tail end is that the be in operation resistance to motion that is subjected to of the blade on plane is also bigger.Therefore, press at present the structure of this blade is improved.
The model utility content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide a kind of blade of rolling rotor type compressor, and to reduce its resistance to motion, it is in service to the bouncing or splash of fluid to reduce blade, thereby reduces the compressor oil yielding rate.
The blade of a kind of rolling rotor type compressor described in the utility model, described rolling rotor type compressor comprises that a casing and is arranged on the rotor of this chassis cavity, and the head end end face of described blade is a convex globoidal, and contacts with described rotor surface, and the tail end end face of described blade is a curved surface.
In the blade of above-mentioned rolling rotor type compressor, the tail end end face of described blade is the conical surface.
In the blade of above-mentioned rolling rotor type compressor, the tail end end face of described blade is an arc surface.
In the blade of above-mentioned rolling rotor type compressor, the tail end end face of described blade is a conical surface.
In the blade of above-mentioned rolling rotor type compressor, the tail end end face of described blade is a convex globoidal.
Owing to adopted above-mentioned technical solution, the utility model is circular-arc or taper by the tail end improved shape with blade, make blade suffered resistance in movement process reduce, also reduced simultaneously blade the bouncing or scratching that be in operation to fluid, thereby can reduce the lost motion of blade, reduce the atomizing of compressor fluid, splash, can reduce the oil yielding rate of compressor, make compressor efficiency and air-conditioning join performance in fact and all be improved.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
See also Fig. 1, Fig. 2, the utility model, it is a kind of blade 1 of rolling rotor type compressor, rolling rotor type compressor comprises that a casing (not shown) and is arranged on the rotor (not shown) of this chassis cavity, head end 11 end faces of blade 1 are convex globoidal, and contact with rotor surface, tail end 12 end faces of blade 1 are curved surface.
As shown in Figure 3, in one of embodiment of the present utility model, tail end 12 end faces of blade 1 are the conical surface, for example, and conical surface etc.
As shown in Figure 4, embodiment of the present utility model two in, tail end 12 end faces of blade 1 are arc surface, for example, convex globoidal etc.
In sum, the utility model has reduced the resistance to motion of blade, has reduced blade and has been in operation to the bouncing/splash of fluid, thereby effectively reduced the oil yielding rate of compressor.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
