The interior crankshaft with eccentric setting, which is characterized in that the connecting rod is symmetrical above and below, the upper and lower end of the connecting rod
It is mounted on the mandril being fixedly connected for piston, the slideway for protruding into for crankshaft and laterally sliding is offered in the middle part of the connecting rod,
Bearing is provided between the crankshaft and slideway, the both sides of the connecting rod are fixedly installed with respectively can limit bearing axial direction
The pressing plate of play is slidably matched between the bearing and slideway inner wall.
In a kind of above-mentioned air compressor machine compression mechanism, the vertical section of the slideway by about two parallel straight lines and
Two symmetrical semi arches surround, and the radius of semi arch is identical as the outer diameter of bearing.
In a kind of above-mentioned air compressor machine compression mechanism, offered in the middle part of the pressing plate identical with slideway shape logical
Hole slot.
In a kind of above-mentioned air compressor machine compression mechanism, the spacing of the upper lower wall of the through-hole groove is less than lower wall on slideway
Spacing.
In a kind of above-mentioned air compressor machine compression mechanism, the bearing is needle bearing.
Compared with prior art, the link design in this air compressor machine compression mechanism is at both ends symmetrical structure, upper and lower ends
It is fixedly connected with the piston, middle part opens up the slideway laterally slided for crankshaft, and needle bearing is arranged between crankshaft and slideway.Work as sky
Band dynamic crankshaft rotates when compressor operation, and the crankshaft touching of rotation makes connecting rod do linear motion up and down, is connected in connecting rod upper and lower ends
Piston moves reciprocatingly in cylinder body, to realize compressed air.The design of this structure changes traditional air compressor machine link mechanism
Working principle avoids the friction damage of link assembly caused by connecting rod is continuously swung, and extend air compressor machine component uses the longevity
Life.
