Below with reference to Fig. 1-Fig. 2, the bent axle 10 according to the rotary compressor of the utility model embodiment is described.
Countershaft 11, eccentric shaft 12 and main shaft 13 is comprised according to the bent axle 10 of the rotary compressor of the utility model embodiment.Specifically, as shown in Figure 1, countershaft 11 and main shaft 13 are located at the both sides of eccentric shaft 12 respectively, the outer surface of at least one of countershaft 11, eccentric shaft 12 and main shaft 13 is provided with phosphate coating processing layer 20, the outer surface at least partially of at least one of the coated countershaft 11 of phosphate coating processing layer 20, eccentric shaft 12 and main shaft 13.
In other words, the bent axle 10 of rotary compressor is divided into the countershaft 11, eccentric shaft 12 and the main shaft 13 that are arranged in order in the lateral direction, wherein, the left end of the eccentric shaft 12 of bent axle 10 is connected with the right-hand member of countershaft 11, the right-hand member of the eccentric shaft 12 of bent axle 10 is connected with the left end of main shaft 13, the outer surface of at least one of the countershaft 11 of bent axle 10, eccentric shaft 12 and main shaft 13 is provided with phosphate coating processing layer 20, the countershaft 11 of the coated bent axle 10 of phosphate coating processing layer 20, eccentric shaft 12 and main shaft 13 at least one at least partially.
Thus, according to the bent axle 10 of the rotary compressor of the utility model embodiment, by arranging phosphate coating processing layer 20 on the outer surface of bent axle 10, not only can ensure the conformability that bent axle 10 assembles, improve the processing quality of the bent axle 10 of rotary compressor, and eliminate the surface finish treating process of bent axle 10, save manufacture cost.
According to an embodiment of the present utility model, countershaft 11 is coaxial with main shaft 13, eccentric shaft 12 and countershaft 11 and main shaft 13 disalignment.
That is, the countershaft 11 of bent axle 10 and the dead in line of main shaft 13, the axis of eccentric shaft 12 does not overlap with the axis of countershaft 11 and main shaft 13, and in the chamber that the housing that bent axle 10 is located at rotary compressor is formed, and bent axle 10 can rotate around the axis of wherein main shaft 13.Thus, the function requirement that can meet the rotary compressor of the bent axle with eccentric operating piston with countershaft 11 and main shaft 13 out-of-alignment eccentric shaft 12 is set in bent axle 10.
In embodiments more of the present utility model, the complete coated countershaft 11 of phosphate coating processing layer 20, eccentric shaft 12 and main shaft 13.
Particularly, as shown in Figure 2, the outer surface of the countershaft 11 of bent axle 10, eccentric shaft 12 and main shaft 13 is all provided with phosphate coating processing layer 20, and this phosphate coating processing layer 20 can be arranged along the end face of the circumference of bent axle 10 and bent axle 10, and inseparable with the outer surface of bent axle 10.
Thus, the outer surface of the complete coated bent axle 10 of phosphate coating processing layer 20, not only ensure that and improves processing quality by the conformability that bent axle 10 assembles, and phosphate coating processing layer 20 can be attached on all outer surfaces of bent axle, simplify the manufacturing process of bent axle 10.Moreover, bent axle 10 after phosphate coating processing layer 20 is coated, without the need to carrying out surface finish process again, greatly reduce manufacture cost high, also reach the object improving operating environment.
Further, according to an embodiment of the present utility model, the thickness of phosphate coating processing layer 20 is 0.5 ~ 1.5 μm.
Be understandable that, the outer surface of phosphate coating processing layer 20 bent axle 10 of complete coated rotary compressor equably, the thickness of this phosphate coating processing layer 20 can control at 0.5 ~ 1.5 μm.Thus, the thickness of phosphate coating processing layer 20 is less, can be attached to forcefully on the outer surface of bent axle 10, meets the processing technique requirement of bent axle 10.
According to an embodiment of the present utility model, surface roughness value≤3.0 of phosphate coating processing layer 20.That is, the outer surface of bent axle 10 is formed with one deck phosphate coating processing layer 20, the surface roughness value of this phosphate coating processing layer 20 is no more than 3.0, and bent axle 10 surface cleanness coated through phosphate coating processing layer 20 is high, roughness good, can remove surface finish process from.
Thus, phosphate coating processing layer 20 is located on the outer surface of bent axle 10, improve the surface cleanness of bent axle 10, surface roughness and dimensional uniformity, ensure that the conformability that bent axle 10 assembles, surface roughness value≤3.0 of phosphate coating processing layer 20, bent axle 10 after phosphate coating processing layer 20 is coated, without the need to carrying out surface finish process again, not only reduces manufacture cost high and improve processing quality, improve operating environment.
It should be noted that, the fabrication processing of the phosphate coating processing layer 20 on the outer surface of bent axle 10 is as follows: first prepared to put in place by satisfactory bent axle 10 foundry goods raw material, then surface finishing is carried out, first fine finishing acceptable product carry out ungrease treatment and remove workpiece surface greasy dirt at 30 ~ 60 DEG C, bent axle 10 after degreasing is washed at normal temperatures, use table is adjusted and is carried out surface adjustment process at normal temperatures afterwards, manganese-series phosphorized dose is used to carry out phosphorating treatment, finally wash, antirust, dry process, namely obtained surface has a bent axle 10 of phosphate coating processing layer 20 without the need to polishing.
According to an embodiment of the present utility model, countershaft 11, eccentric shaft 12 and main shaft 13 are integrally formed.Thus, be integrally formed the integrally-built stability that not only ensure that bent axle 10, make the compact structure of whole bent axle 10, and convenient formation.
Below in conjunction with concrete comparative example and embodiment, the bent axle 10 to rotary compressor is described in detail.
Comparative example one
Traditional manganese-series phosphorized treatment process is thick-film type phosphating process, namely carries out surface manganese system phosphorating treatment after bent axle fine finishing, carries out the technique of surface finish after phosphorating treatment again.The bent axle thickness that this technique obtains about 3 ~ 5 μm, and the thickness difference of the different parts of bent axle is large, the electron microscopic picture of the manganese-series phosphorized bent axle of tradition adopting the treatment process of prior art to obtain as shown in Figure 3, the film thickness dimensional uniformity of the bent axle of this structure is poor, the outer surface phosphatization dust of the bent axle after phosphorating treatment remains, accumulation is many, surface cleanness is poor, there is corrosion, stain, aberration, beat trace, the phenomenons such as foreign matter attaches, surface roughness is poor, phosphating coat crystal is thick, not fine and close, therefore need after phosphorating treatment to carry out surface finish process again to ensure the conformability that bent axle assembles, therefore, it is high to there is manufacture cost in traditional crankshaft processing technology, processing quality is unstable, the deficiencies such as operating environment difference.
