Footpath is R1, and the radius of the second hole section 3112 is that R2, R1 and R2 meet: 1mm≤R1-R2≤2mm.Thus can ensure that the first hole section
Gap between internal perisporium and the periphery wall of bent axle 4 of 3111, so that the internal perisporium of the first hole section 3111 and the periphery of bent axle 4
The groove internal memory limited between wall puts refrigerator oil, strengthens loading capacity of oil film, thus reduces friction loss, and then improves
The coefficient of performance of compressor 100.
In embodiments more of the present utility model, as it is shown on figure 3, step surface 3113 is formed as inclined-plane and bottom-up
Direction on outward-dipping.Thus, it is possible to make refrigerator oil flow along step surface 3113 towards the direction of bent axle 4, thus strengthen
Loading capacity of oil film, reduces friction loss, and then improves the performance of compressor 100.
Alternatively, on direction from top to bottom, the cross-sectional area of the first hole section 3111 is gradually reduced.Thus, it is possible to more
Good enhancing loading capacity of oil film, reduces friction loss, improves the performance of compressor 100 to a certain extent.At the same time it can also be
Increase the multiformity of bearing 31 structure.Preferably, as it is shown on figure 3, the position away from the second hole section 3112 of the first hole section 3111
Place has chamfering 3114.Thus it is easy to the installation of bent axle 4, burr can be removed simultaneously.
In embodiments more of the present utility model, on upper and lower direction, the height of hub portion 311 is that H, H meet:
0.02 ＜ L/H≤0.125.Thus, both can reduce the length of friction pair between bearing 31 and bent axle 4, can guarantee that again bearing 31
The reliability that bent axle 4 is supported, thus improve the reliability of compressor 100 work.
Alternatively, the part as in figure 2 it is shown, hub portion 311 and flange portion 312 are formed in one.Thus can simplify hub portion
311 and the assembly process of flange portion 312, improve efficiency of assembling.
Compressor 100 according to this utility model embodiment, including the bearing 31 of above-mentioned compressor 100.
Compressor 100 according to this utility model embodiment, by arranging the bearing 31, Ke Yiti of above-mentioned compressor 100
The coefficient of performance of high compressor 100.
Describe according to the compressor 100 of one specific embodiment of this utility model below with reference to Fig. 1-Fig. 3, described below
It is exemplary, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.
As it is shown in figure 1, according to the compressor 100 of this utility model embodiment, including housing 1, electric machine assembly 2, compression group
Part 3 and bent axle 4, in electric machine assembly 2 is located at housing 1 and include stator 22 and be rotatably arranged at the rotor 21 within stator 22,
