Accompanying drawing explanation
Fig. 1 is the crankshaft structure schematic diagram of this utility model one embodiment；
Fig. 2 is the structural representation of the rotary compressor of this utility model one embodiment.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And bent axle of the present utility model and rotary compressor are further elaborated by embodiment.Should be appreciated that
Specific embodiment described herein is only used for explaining this utility model, is not used to limit this utility model.
Seeing figures.1.and.2, the bent axle of this utility model one embodiment, including long shaft part 101, short shaft part 102
And the off-centre operation section 103 being connected between long shaft part 101 and short shaft part 102.Long shaft part 101 is multidiameter.
The long shaft part 101 of bent axle is processed into stairstepping so that the machining accuracy of bent axle reduces.
Wherein, long shaft part 101 includes first paragraph axle 1011 and second segment axle 1012, the first paragraph being sequentially connected with
Axle 1011 is away from off-centre operation section 103, and second segment axle 1012 is adjacent to off-centre operation section 103, first paragraph axle 1011
External diameter less than the external diameter of second segment axle 1012.First paragraph axle 1011 is used for being connected with the rotor of motor, the
Two-stage nitration axle 1012 is for coordinating with flange.The external diameter of first paragraph axle 1011 is less than the external diameter of second segment axle 1012,
Thus the diameter of bore of rotor can reduce accordingly, make the reduction of motor magnetic density, efficiency improve, promote
The overall performance of compressor.
As a kind of embodiment, first paragraph axle 1011 is provided with external screw thread, it is preferable that first paragraph axle
The end of 1011 arranges external screw thread, nut can be used to coordinate with the external screw thread of first paragraph axle 1011 end and by
One section of axle 1011 is fixed on rotor 104.Certainly first paragraph axle 1011 also can be with rotor 104
Threaded engagement connects.
Wherein, the quantity of off-centre operation section 103 can be two or more, and two or more off-centre operation section 103 interval sets
Put.Being correspondingly arranged a roller in each off-centre operation section 103, arranging multiple off-centre operation section 103 can realize
The multi-stage compression of compressor.
This utility model further relates to a kind of rotary compressor, as in figure 2 it is shown, rotary compressor includes electricity
Machine rotor 104, the first paragraph axle 1011 of the long shaft part 101 of bent axle is placed in the endoporus of rotor 104,
The first paragraph axle 1011 of long shaft part 101 connects rotor 104, the rotation Tong Bu with rotor of long shaft part 101
Turn.
The second segment axle 1012 of the long shaft part 101 of bent axle is placed in the flange 105 of rotary compressor, and second
Section axle 1012 is slidably connected with flange 105, i.e. second segment axle 1012 can rotate relative to flange 105.
This rotary compressor can be horizontal compressor or vertical compressor.
The bent axle of above example and rotary compressor, the long shaft part 101 of bent axle is multidiameter, its structure
Simply, convenient processing and manufacture, reduce bent axle polished surface length, only need to be to second coordinated with flange 105
The surface of section axle 1012 carries out polish, it is not necessary to the surface of first paragraph axle 1011 is carried out polish,
Reduce processing cost；Meeting the situation that rotary compressor is rotated by rotor 104 band dynamic crankshaft
Under, it is possible to reduce the diameter of bore of rotor 104, make the reduction of motor magnetic density, efficiency improve, thus
