Abstract
The utility model is a non-cylinder piston which is applied for piston-type compressor. The characteristics are: the guiding end of the piston outer surface is provided with two symmetric arc grooves to form a guiding surface with two arc side wings; thus, the friction area between the guiding end and the cylinder hole is reduced, the fiction is reduced and the restriction of the piston cylinder degree is weakened so that the processing is more convenient; the utility model is specially suitable for improvement of piston-type cooling compressors.
Description
(1) technical field: the utility model relates to the component of refrigeration compressor, is a kind of non-cylindrical piston that is applied to piston compressor.
(2) background technique: at present, the piston that adopts in the compressor is cylindrical piston, the sealed end (front end) and the guide end (rear end) that are piston are columniform one, this has cylindricity preferably with regard to the front and back ends that requires piston, the requirement on machining accuracy height, otherwise the front/rear end friction can be bigger, influence the wearing and tearing of compressor, even stuck phenomenon occurs.
(3) summary of the invention: the purpose of this utility model is will solve the piston guide end because the bad defective that produces of form and position tolerance reduces the friction of compressor, avoids stuck fault, and a kind of non-cylindrical piston that is applied to piston compressor is provided.
Concrete scheme of the present utility model is: piston by the cylindrical non-cylindrical that changes into, is promptly left the arc groove of two symmetries at the outer surface of piston guide end, form two flank circular arc guide surfaces.
The utlity model has following advantage:
1. can ignore high requirement, can guarantee well in the production process, needn't drop into higher surveying instrument, can reduce the product waste product, enhance productivity the piston cylindricity.
2. because the piston guide end is a non-cylindrical, change both wings circular arc guiding into, reduced the friction area, reduced friction, can cut down the consumption of energy like this, improve mechanical efficiency by the cylinder guiding.
3. lead with non-cylindrical owing to guide end, like this, guide end and cylinder interporal lacuna cavity volume strengthen, can accumulate more oil, in the piston running, the lubricated and cooling effect that this oil can be good to the cylinder hole, because the kinematic pair temperature reduces, then the wearing and tearing in the movement process reduce, working life of elongated component preferably, the working life of improving complete machine simultaneously.
(4) description of drawings:
Accompanying drawing is a perspective view of the present utility model.
(5) embodiment:
Referring to accompanying drawing, the utility model is a upper and lower arc groove 2 and 4 of leaving two symmetries at the outer surface guide end of pot type piston, forms two flank circular arc guide surfaces 1 and 3 and promptly can be made into.
Claims (1)
1. non-cylindrical piston that is applied to piston compressor is characterized in that: leave the arc groove of two symmetries at the outer surface of piston guide end, form two flank circular arc guide surfaces.
