The piston pin is a cylindrical pin arranged on the skirt part of the piston, the middle part of the piston pin penetrates through the small end hole of the connecting rod and is used for connecting the piston and the connecting rod, and the function of the piston pin is to transmit the gas acting force born by the piston to the connecting rod or enable the small end of the connecting rod to drive the piston to move together. To reduce weight, piston pins are typically made of high quality alloy steel and are hollow.
The CN205478203U retrieval discloses a compressor piston pin lubricating structure, which comprises a piston pin, a connecting rod, a crankshaft and a piston, wherein an oil outlet is formed in an eccentric shaft of the crankshaft, a top hole is formed in the top of the piston pin, one or more side holes are formed in the side surface of the piston pin, and the side holes are communicated with the top hole. After the lubricating oil is thrown out from an oil outlet on the eccentric shaft through centrifugal force, one part of the lubricating oil is thrown into a top hole of the piston pin, flows to a side hole of the piston pin and reaches the surface of the piston pin, and even if the connecting rod does not have a central oil hole, the piston pin can be effectively lubricated.
However, the inventor finds that the technical scheme still has at least the following defects: in the device, lubricating oil is thrown to the surface of the piston pin through centrifugal force, so that the lubricating effect on the piston pin is achieved, however, when the lubricating oil is thrown out, the lubricating oil cannot fall onto parts outside the piston pin, the phenomenon of lubricating oil waste exists, and impurities and scraps generated due to friction in the transmission process cannot be collected and processed.
In view of this, the present invention is provided.
