Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Fig. 1 is the structural representation of the utility model embodiment's crankshaft structure.As shown in Figure 1, the crankshaft structure of the present embodiment comprise major axis section 10, minor axis section 30 and be connected to major axis section 10 and minor axis section 30 between crank 20, crankshaft structure includes the main oil gallery 11 that runs through vertically major axis section 10, and on the periphery wall of the part that is rotatably assorted of major axis section 10, edge is circumferentially provided with annular groove 12.When the major axis section 10 of this crankshaft structure is rotatably assorted with flange 40, the annular groove 12 that is arranged on the part that is rotatably assorted of major axis section 10 can reduce the area of contact of bent axle and flange 40, reduce the wearing and tearing between bent axle and flange 40, reduce the mechanical wear of compressor, extend the working life of compressor.In addition, this annular groove 12 is interior can also store lubricant oil, on the one hand can be constantly to make-up oil between bent axle and the surface of contact of flange 40, can be so that there be thicker oil film on bent axle and flange contact facings, lubricated more abundant, the heating value that minimizing bent axle and flange are 40, can also seal the gap between bent axle and flange 40 on the other hand, reduce high pressure gas leakage amount, improve compressor performance.Annular groove 12 herein also can be connected with the oil guide slot on flange 40, thereby makes lubricant oil flow to annular groove 12 from oil guide slot, supplements the lubricant oil in annular groove 12.
Preferably, be also provided with oil outlet 13 in major axis section 10, oil outlet 13 is communicated with annular groove 12 and main oil gallery 11.This oil outlet 13 can be delivered to annular groove 12 by the lubricant oil in main oil gallery 11, thereby supplements well the lubricant oil in annular groove 12, and make lubricant oil can sufficient lubrication bent axle and flange 40 between surface of contact.
A plurality of annular grooves 12, along the axially spaced-apart setting of major axis section 10, can reduce the area of contact between bent axle and flange 40 further, and increase the lubricant oil between bent axle and the surface of contact of flange 40.
In the present embodiment, the h1 degree of depth of annular groove 12 is major axis section 10 diameters
0.01～0.03 times, the width w1 of annular groove 12 is major axis section 10 diameters
0.1～0.4 times.This kind of structure prevents oil leakage when can guarantee lubricating oil flow, makes lubricant oil obtain maximized application.In addition, above-mentioned annular groove 12 also can not affect the structural strength of bent axle, can will the impact of crankshaft structure be dropped to and be minimized.
Preferably, the diameter of oil outlet 13 is less than or equal to major axis section 10 diameters
0.3 times.
In major axis section 10, be also provided with along the annular oil storage tank 14 of the circumferential extension of major axis section 10.The effect of annular oil storage tank 14 is substantially the same with the effect of annular groove 12, but annular groove 12 is mainly lubricated supplementing of oil by oil outlet 13, and supplementary lubricant oil mainly comes from the lubricant oil in main oil gallery 11.And annular oil storage tank 14 is not communicated with main oil gallery 11 by oil outlet 13, but be lubricated supplementing of oil by the oil groove on flange 40.
In the present embodiment, the degree of depth h2 of annular oil storage tank 14 is major axis section 10 diameters
0.01～0.03 times, the width w2 of annular oil storage tank 14 is major axis section 10 diameters
0.1～0.4 times.This kind of structure is also can be to the better lubrication effect that is combined with between bent axle and flange 40 when not affecting the structural strength of bent axle.
Preferably, annular oil storage tank 14 center and major axis section 10 are that annular groove 12 center and major axis section 10 are near 0.8 to 1.2 times of the distance L between the end face of minor axis section 30 one end near the distance L 1 between the end face of minor axis section 30 one end.
As shown in Figure 2, according to a kind of compressor of the utility model embodiment, comprise crankshaft structure and the flange 40 that is set in the major axis section 10 of crankshaft structure, this crankshaft structure is above-mentioned crankshaft structure, and annular groove 12 is arranged on the mating area of flange 40 and major axis section 10.
Preferably, annular groove 12 center overlaps with the end face place face of flange 40, wherein on the intermediate cross-section that is centered close to annular groove 12 of annular groove 12, and is positioned at the center of the central axis segment of annular groove 12.The contact length of the edge of close minor axis section 30 one end of annular groove 12 and major axis section that major axis section 10 is bent axle near the distance between the end face of minor axis section 30 one end 10 and flange 40 now.
Under the effect of High Rotation Speed operation pressurized gas acting, above-mentioned annular groove 12, annular oil storage tank 14, on the one hand the area of contact of bent axle and flange 40 is reduced, reduced between bent axle and flange and worn and torn, reduced compressor mechanical wear, on the other hand, lubricant oil is discharged from oil outlet 13, flows to annular groove 12.Meanwhile, lubricant oil, by the oil guide slot on flange 40, flows to annular oil storage tank 14.Be stored on the surface of contact that lubricant oil in annular groove 12, annular oil storage tank 14 makes bent axle and flange 40 and have thicker oil film, lubricated more abundant, can reduce the heating value between bent axle and flange 40.In addition, too much lubricant oil in annular groove 12, annular oil storage tank 14, also salable bent axle and flange gap, reduce high pressure gas leakage amount, improves compressor performance.
Certainly, be more than preferred implementation of the present utility model.It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model basic principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
