Abstract
The utility model relates to a compressor plastic piston pin, which comprises a cylindrical piston pin body, wherein an interference fit part is integrally formed at one end of the cylindrical piston pin body; and a transverse groove is formed on the end face of the interference fit part. The compressor plastic piston pin is simple in structure, scientific and reasonable in design, easy to manufacture, low in cost, resistant to high temperature, high in mechanical performance, high in self-lubricity and high in abrasion resistance, the loading capacity of a compressor is improved, and the low-high back pressure of the mechanical abrasion resistance of the compressor is realized, so the application range of the compressor is expanded, and the compressor plastic piston pin is safe and reliable.
Description
Technical field
The utility model belongs to compressor piston pin field, especially a kind of compressor plastic piston pin.
Background technique
For further improving compressor efficiency, compressor producer all adopts and reduces the wrist pin diameter, reduces the way of area of contact; Raise the efficiency, but its abrasion resistance properties reduces significantly, can't satisfy the needs of reliability; Make the method that reduces the wrist pin diameter, be restricted.The degree of finish on wrist pin surface and cylindricity are extremely important for reducing friction, and at present, because normal quenching can't reach requirement, way is that wrist pin is carried out the later stage nitriding treatment usually, could guarantee degree of finish and cylindricity but need finish grind cylindrical several times.This process deviation is bigger, and is high for the requirement of equipment precision, and for compressor industry with keen competition, the cost reduction runs into bottleneck.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology; A kind of compressor plastic piston pin is provided, this wrist pin is simple in structure, design science rationally, make simple, cost is lower, high temperature resistant, superior, self lubricity is good, wear resistance is good.
The utility model solves its technical problem and realizes through following technological scheme:
A kind of compressor plastic piston pin comprises cylindrical piston pin body, and it makes interference fit portion in cylindrical piston pin body one end one, on the interference fit end surface, makes straight groove.
And described cylindrical piston pin body and interference fit portion all adopt polyether-ether-ketone resin to make.
Advantage of the utility model and beneficial effect are:
1, this compressor plastic piston pin comprises cylindrical piston pin body; It makes interference fit portion in cylindrical piston pin body one end one, on the interference fit end surface, makes straight groove, and cylindrical piston pin body and interference fit portion all adopt polyether-ether-ketone resin to make; This structure reduces compressor mechanical output loss 0.5-2W; Reduce the assembling link, save labour turnover, effectively improve compressor rotary speed; Adopt the polyether-ether-ketone resin of high carbon fiber content, can further reduce wrist pin diameter 0.5-1mm.
2, the utility model is simple in structure, design science is reasonable, making is simple, cost is lower, high temperature resistant, superior, self lubricity is good, wear resistance is good; Improve the load capacity of compressor; The anti-mechanical wear ability of one compressor is reached from low-high back pressure; Thereby having widened the using scope of a compressor, is a kind of safe and reliable compressor plastic piston pin.

Embodiment
Through specific embodiment the utility model is done further to detail below, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of compressor plastic piston pin; Comprise cylindrical piston pin body 3; It makes interference fit portion 2 in cylindrical piston pin body one end one, on the interference fit end surface, makes straight groove 1, and described cylindrical piston pin body and interference fit portion all adopt polyether-ether-ketone resin to make.
The utility model can reduce compressor mechanical output loss 0.5-2W, reduces the assembling link, saves labour turnover; Effectively improve compressor rotary speed,, can be increased to 10000-20000RPM from the highest 5000RPM at present; Adopt the polyether-ether-ketone resin of high carbon fiber content, carbon fiber content is not less than 20%, the graphite fiber direction; Perpendicular to the piston motion direction, can further reduce wrist pin diameter 0.5-1mm.Add self lubricating material PTFE in the raw material, content is not higher than 15% and need not to worry to oil, can be near oil-free lubrication.
