Abstract
The utility model relates to an oil extracting needle which can cause the lubricating oil in a reciprocating piston type compressor body to generate a proper amount of oil mist attached on a dry friction pair, forming oil film, and thus, the lubricating effect is achieved. The oil extracting needle is a single needle. The upper end of the needle forms a sealed annular shape, and the lower end forms an arc shape in limited degrees. The annular part of the upper end is inserted into the end opening slot of the big top end of a connecting rod. The utility model is hung on a connecting screw-bolt in natural sagging shape. The utility model has a detachable structure which can sufficiently utilizes the sticky property of oil. Thus, the oil extracting needle can instantly generate deflective swing when contacting and separating with an oil surface. The formation of oily mist amount can be effectively reduced. The oil consumption of a compressor can be decreased. According to tests, the oil consumption can be decrease by more 40%.
Description
The utility model is the splash lubrication element of miniature Reciprocting piston compressor.
The lubricating system of present miniature Reciprocting piston compressor friction pair is all by splashing, and its form has two kinds: band oil ring and the fixed pin of buying oil, and its shortcoming is, (1) though the oil consumption of band oil ring is more stable, but the fabricating cost height, complex process, consumption worker feed consumption, (2) the fixed pin fabricating cost of buying oil is low, but when hitting pasta, the oil mass that splashes is big, when breaking away from pasta, the oil mass of taking out of is bigger, and promptly the mist of oil amount that produces increases.Owing to exist the interior pressure that is changing in the body, interior pressure will make the unnecessary mist of oil in the body pass through spiracle respectively, and piston ring gap leaks in atmosphere and the gas holder, has so just formed oil consumption.Each micro-compressor manufacturing firm does not seek to solve the optimum method that reduces oil consumption as yet at present.
To be that design is a kind of make miniature Reciprocting piston compressor reduce oil consumption to the purpose of this utility model, satisfies the current energy-conservation movable pin of buying oil.
The purpose of this utility model is to adopt on the Placement of buy oil pin and connnecting rod big end of movable structure, promptly bend or the sheetmetal punching out forms that the pin upper end of buying oil is closed ring by steel wire, the lower end is certain radian, top ring inserts in the connnecting rod big end open-topped groove, hang on the connecting bolt, be the sagging shape of nature, be a kind of movable structure.The movable pin of buying oil is hitting on the oily direction, and promptly the connecting rod swing direction can be done greater than 180 ° freely swing, and in hitting oily process, the pin of buying oil is owing to be subjected to the viscous effect of fluid, and its motion is blocked, and produces beat, thereby effectively reduces the formation of mist of oil amount; Finally reach the purpose that reduces oil consumption.
Accompanying drawing 1 is the utility model movable needle construction schematic representation of buying oil, and accompanying drawing 2 is the pin parts drawing of buying oil, and 1 is connnecting rod big end among the figure; 2 is connecting bolt; 3 are the pin of buying oil.
In conjunction with the accompanying drawings, provide embodiment of the present utility model.
The movable pin of buying oil is assembled by connnecting rod big end 1, connecting bolt 2 and the pin 3 of buying oil.Buy oil pin 3 as shown in Figure 2, and its upper end is the closed loop shape, and the lower end is certain radian, and length is 30～60mm, and the pin diameter of buying oil that steel wire is bent into is 1～3mm.Present embodiment is single, and its length, diameter and rigging position are looked different requirements can do corresponding change, and the pin top ring of buying oil inserts in the connnecting rod big end open-topped groove, hangs on the connecting bolt, is the sagging shape of nature, for a kind of movable structure as shown in Figure 1.
Adopt the utility model movable pin of buying oil, micro-compressor is tested, the result shows: oil consumption can descend more than 40%, has reached " power air compressor quality grading " standard A level product level.
Claims (2)
1, the movable pin of buying oil, it is assembled by connnecting rod big end, connecting bolt and the pin of buying oil, the pin that it is characterized in that buying oil is single, the upper end is the closed loop shape, the lower end is certain radian, and top ring inserts in the connnecting rod big end open-topped groove, hangs on the connecting bolt, be the sagging shape of nature, be a kind of movable structure.
2, according to the said movable of claim 1 pin of buying oil, the pin upper end that it is characterized in that buying oil is the closed loop shape, and the lower end is certain radian, and length is 30～60mm, and the pin diameter of buying oil that steel wire is bent into is 1～3mm.
