The utility model overcomes compressor piston pin among the prior art does not possess good lubricating structure's defect, through setting up oil groove and oil storage hole, it can be used for storing lubricating oil to can effectually lubricate in the course of the work, it can also store impurity and piece that produce because of the friction in the transmission process simultaneously.
Description
Technical Field
The utility model relates to a compressor field especially relates to a compressor piston pin.
Background
Piston pin on the piston compressor is a connecting piece of connecting piston and connecting rod, and whole assembly is inboard in the piston, and during operation connecting rod promotes the piston and makes reciprocating motion, when the compressor area load work, takes place violent friction and wearing and tearing between connecting rod and the piston pin, also can take place violent friction and wearing and tearing between piston and the piston cylinder inner wall, need guarantee sufficient lubrication between the above-mentioned fitting surface this moment, and the present piston pin that is used for the compressor does not all possess good lubricating structure. For example: the invention discloses a piston, a piston pin, a piston assembly and an assembling method thereof as well as a compressor comprising the piston assembly, wherein the end part of the piston pin is provided with a flat boss, the boss comprises an arc surface connected with a cylinder of the piston pin and at least one side plane connected with the end surface of a piston pin shaft, the boss is provided with an elastic pin hole, the elastic pin hole is arranged in a penetrating way through the side plane of the boss, the piston is a cavity with one open end and the other closed end, the piston is provided with an upper piston pin hole, the open end is provided with a notch corresponding to the boss of the piston pin, the notch extends from the open end to be communicated with the piston pin hole, and an elastic pin hole is arranged on a solid part close to the closed end The lubricating effect is achieved between the piston and the inner wall of the piston cylinder.
SUMMERY OF THE UTILITY MODEL
The utility model relates to an overcome the compressor piston pin among the prior art and do not possess good lubricating structure, provide a compressor piston pin that possesses the lubrication action.
In order to realize the purpose of the utility model, the utility model discloses a following technical scheme realizes:
the compressor piston pin comprises a piston pin body, wherein one end part of the piston pin body is provided with a positioning pin hole which is arranged along the radial direction and penetrates through the piston pin body, an oil storage hole is further axially formed in the end part of the piston pin body on one side of the positioning pin hole, one end of the oil storage hole is communicated with the end part of the piston pin body, the other end of the oil storage hole penetrates into the piston pin body, the oil storage hole and the positioning pin hole are perpendicular to each other, and an oil groove which is arranged along the radial circumference of the piston pin body is further.
Preferably, the length of the oil storage hole is 1/5 the length of the piston pin body.
Preferably, the diameter of the oil reservoir hole is 2 times the diameter of the pilot pin hole.
Preferably, the oil groove is circular arc-shaped.
Preferably, the oil groove has a depth of 1/30 the diameter of the piston pin body.
Therefore, the utility model provides a piston pin its is provided with along its radial a week's oil groove at stopper pin body middle part, and it can be used for storing lubricating oil to can effectually lubricate in the course of the work. Simultaneously the utility model discloses still radially being provided with an oil storage hole at the tip that the piston pin body is located locating pin hole one side, it can play the storage lubricating oil and then play the lubrication action equally, and it can also store impurity and piece that produce because of the friction in the transmission process simultaneously.
