The bent axle 100 of the compressor according to this utility model embodiment, the song of the compressor are described below with reference to Fig. 1-Fig. 5
Axle 100 can be used for rotary compressor.
As Figure 1-Figure 5, the bent axle 100 according to the compressor of this utility model embodiment, bent axle 100 is with along length
Its center oilhole 10 is run through in direction, and bent axle 100 includes:First paragraph 20 and second segment 30.
Specifically, line a centered on the centrage of first paragraph 20, first paragraph 20 are provided with eccentric part 210, eccentric part 210
Centrage centered on line b, the lower end of second segment 30 is connected with the upper end of first paragraph 20, line centered on the centrage of second segment 30
In c, centrage a, centrage b and centrage c are generally aligned in the same plane, and centrage b and centrage c is located at centrage a both sides.
It should be noted that in compressor operating, bent axle can be by gas force, balance weight rotating inertia force, and radial direction is not
Balance magnetic pull effect, wherein Unbalanced-magnetic-pull include quiet eccentric magnetic pull and dynamic bias magnetic pull effect.Through imitative
True analysis and experimental verification, gas force is the main mechanical factor for causing bent axle root inordinate wear, and dynamic bias magnetic pull is
Cause the main mechanical factor of bent axle upper end inordinate wear.The generation of dynamic bias magnetic pull is mainly with balance weight with postponing generation
Rotating inertia force is relevant.During compressor operation, as rotating inertia force is acted on, crankshaft end can occur flexure so as to deviate
Center of rotation, the rotor for assembling therewith also can deviate while producing dynamic with stator center, and thus dynamic bias magnetic pull produces.
From the point of view of the essence that driven eccentric magnetic pull is produced, as long as rotor center is had with its stator center (i.e. center of rotation) partially
From dynamic bias magnetic pull can be produced.Try to so that rotor center has rightabout with deformation pre- inclined with stator center
From, you can reduce the dynamic offset of rotor in operation process, dynamic bias magnetic pull is substantially reduced, so as to realize improving bent axle
Wear and tear abnormal problem for upper end.
According to the compressor crank shaft 100 of this utility model embodiment, by bent axle 100 is set to first paragraph 20 and second
Section 30, makes the centrage b of the centrage c and eccentric part 210 of second segment 30 be located at the both sides of the centrage a of first paragraph 20, can be with
So that the centrage of the centrage of first paragraph 20 and second segment 30 has a pre- bias, in compressor operating, this is pre- partially
The dynamic eccentric magnetic pull at 100 upper end motor position of bent axle can be effectively reduced from amount, so as to effectively improve 100 upper end of bent axle
The abnormal problem of abrasion, and then improve the whole service life of compressor crank shaft 100.
According to one embodiment of the present utility model, as shown in figure 3, the distance between centrage a and centrage c are e, e
Meet:0 < e≤0.45mm.Thus, it is possible to make between the first paragraph 20 of bent axle 100 and second segment 30, the presence of an eccentric amount e,
Through verification experimental verification, when e meets:During 0 < e≤0.45mm, during offset can cause 221 center of stator and rotor 222 to rotate
Feel in a pre- bias, in compressor operating, the pre- bias effectively can be reduced because dynamic bias magnetic pull causes
100 upper end of bent axle abrasion, so as to improve the service behaviour of compressor crank shaft 100, improve the service life of compressor.
