Abstract
The utility model discloses a compressor piston sells lubricating structure, including piston pin, connecting rod, bent axle and piston, be equipped with the oil -out on the eccentric shaft of bent axle, the top of piston pin is equipped with the apical pore, and the side of piston pin is equipped with one or more side opening, side opening and apical pore intercommunication. Lubricating oil throws away the back through centrifugal force from eccentric epaxial oil -out, and some gets rid of the apical pore into the piston pin, flows to the side opening of piston pin again and arrives the piston pin surface, even the connecting rod does not have central oilhole, still can effectively lubricate the piston pin, and the big aperture of some connecting rod of specially adapted is not processed separately exempts from to process the connecting rod.
Description
Technical field
This utility model relates to refrigeration compressor art, specifically a kind of compressor piston pin lubrication system.
Background technology
Existing refrigeration compressor piston pin lubrication system is as shown in Figure 1: lubricating oil flow to the oil groove 4 set by crankshaft eccentric shaft 3 side by the oil groove 2 that rotary centrifugal force is set from bent axle major axis 1, pass through rotary centrifugal force again, a part is got rid of to piston face 5, arrive piston pin 8 surface after being partly on connecting rod 6 set center oilhole 7, lubricate piston pin 8.Said structure is applicable to the connecting rod of post-production, after connecting rod center oil hole machined is good, reprocesses the big aperture of connecting rod.But what aperture big for some connecting rod was processed the most separately exempt from processes connecting rod, and connecting rod centre drill oilhole can affect the cylindricity of the big aperture of connecting rod, increase frictional dissipation, and hole of cannot buying oil, connecting rod center the most just cannot use above-mentioned technology to come to piston pin and provide and lubricates.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of compressor piston pin lubrication system, even if connecting rod center is without oilhole, and still can effectively lubricating piston pin.
For solving above-mentioned technical problem, this utility model one compressor piston pin lubrication system includes that piston pin, connecting rod, crankshaft and piston, the eccentric shaft of described bent axle are provided with oil-out；The top of described piston pin is provided with apical pore, and the side of described piston pin is provided with one or more side opening, and described side opening connects with described apical pore.
Above-mentioned a kind of compressor piston pin lubrication system, the side opening set by described piston pin side is through hole or blind hole.
Above-mentioned a kind of compressor piston pin lubrication system, described connecting rod internal Bu She center oilhole.
This utility model is owing to have employed above-mentioned technical pattern, by centrifugal force oil-out (oil outlet or oil groove) from eccentric shaft, lubricating oil throws away that (oil groove preferably offered from side throws away, also the oil outlet can offered from top throws away), a portion oil is got rid of to piston face, lubricates piston；Another part gets rid of the apical pore into piston pin, then flow to the side opening of piston pin, arrives piston pin surface, lubricates piston pin.Such that make connecting rod non-stop layer oilhole, still can effectively lubricating piston pin, exempting from of being particularly well-suited to that the big aperture of some connecting rod processes the most separately processes connecting rod.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing refrigeration compressor piston pin lubrication system；
Fig. 2 is the schematic diagram of this utility model refrigeration compressor piston pin lubrication system.
Detailed description of the invention
As in figure 2 it is shown, the piston pin lubrication system of this utility model refrigeration compressor includes bent axle 11, connecting rod 12, piston pin 13 and piston 14, Bu She center, the inside oilhole of connecting rod 11.Bent axle 11 includes major axis 15 and eccentric shaft 16, and major axis 15 surface is with helical oil groove 17, and bottom is provided with eccentric oilhole 18, and the side of eccentric shaft 16 is provided with oil groove 20(can also arrange oil outlet at its top), lubricating oil can be thrown away by centrifugal force.The top of piston pin 13 is provided with a circular apical pore 21, and it can also be multiple that the side of piston pin is provided with the quantity of a side opening 22(side opening 22), side opening 22 is connected with apical pore 21.Side opening 22 both can be through hole, it is also possible to for blind hole, be preferably single blind hole.
During work, lubricating oil arrives helical oil groove 17 after being inhaled into eccentric oilhole 18 by centrifugal force, eccentric shaft 16 is flowed into again by oilhole 19, the last centrifugal force that passes through again throws away from the oil groove 20 set by eccentric shaft 16 side, a part gets rid of the surface to piston 14, another part gets rid of to the apical pore 21 set by piston pin 13 top, then flows into side opening 22 and arrive the surface of piston pin 13, lubricates piston pin 13.
Claims (3)
1. a compressor piston pin lubrication system, including piston pin, connecting rod, crankshaft and piston, the eccentric shaft of described bent axle is provided with oil-out, it is characterized in that, the top of described piston pin is provided with apical pore, and the side of described piston pin is provided with one or more side opening, and described side opening connects with described apical pore.
2. a kind of compressor piston pin lubrication system as claimed in claim 1, it is characterised in that the side opening set by described piston pin side is through hole or blind hole.
