Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but does not makees
For limitation of the invention.
As shown in Fig. 4 to Fig. 9, the embodiment of the present invention provides a kind of compressor crank shaft, and it is special
It is applicable to micro-compressor use.
As shown in Figure 4 and Figure 5, this compressor crank shaft includes that axis body, axis body include shaft part A etc.
Some.Wherein, being formed with a back-up ring mounting groove 1 on shaft part A, this back-up ring is installed
Shaft part A is divided into two parts by groove 1, i.e. for install rotor 2 rotor section 3 and
First shaft part 4, rotor section 3 lays respectively at the both sides of back-up ring mounting groove 1 with the first shaft part 4, and
Rotor section 3 is identical with the diameter of axle of the first shaft part 4.Therefore, the compressor crank shaft in the present invention does not has
There is employing ledge structure of the prior art that rotor 2 is axially positioned.
During installation, a back-up ring 7 as shown in Figure 5 can be set in back-up ring mounting groove 1, the most just
It is to say that back-up ring 7 is stuck in this back-up ring mounting groove 1.So, it is installed to rotor section 3 when rotor 2
After on, so that it may utilize back-up ring 7 axially positioning rotor 2, existing without arranging
Ledge structure in technology, so that back-up ring 7 both sides can use the identical diameter of axle.
Visible, owing to have employed technique scheme, the diameter of axle of back-up ring 7 both sides of the present invention will not
Change, i.e. will not produce ledge structure so that the minimum diameter ratio of bent axle is in prior art
Diameter want big, thus improve the intensity of compressor crank shaft, also be no longer necessary to it is carried out point
Section grinding, improve the manufacturability of processing, reduce compressor crank shaft difficulty of processing and
Cost, has simple in construction, easy to process, the feature of low cost.
Circumferentially positioned in order to realize rotor 2, the present invention also can form one on rotor section 3
Individual or multiple trimmings 5 for rotor 2 is axially positioned.Such as, shown in Fig. 6 and Fig. 7
In embodiment, can be as using a trimming in the prior art；And in the reality shown in Fig. 8
Executing in example, the number of trimming 5 can also be two, and the two trimming 5 relative tilt set
Put.It is further preferable that the angle between the two trimming 5 is 5 to 10 degree, in case spline is sub
Wrongly installed direction during 2 assembling.
In a particularly preferred embodiment, the compressor crank shaft in the present invention in use,
Can also be without using back-up ring 7, now owing to having two trimmings, position, therefore having at two
The situation of rotor discontinuity equalization will not be produced.
As shown in Figure 10, present invention also offers a kind of compressor, bent including above-mentioned compressor
Axle 6.Such as Figure 10, the compressor crank shaft of this compressor is by being arranged on the gear of compressor crank shaft 6
Back-up ring in circle mounting groove 1 can realize the axial location of rotor, it is therefore not necessary to use existing skill
Ledge structure in art, not only increases the intensity of compressor crank shaft, is also no longer necessary to enter it
Row step grinding is processed, and improves the manufacturability of processing, reduces the difficult processing of compressor crank shaft
Degree and cost.
Such as Figure 10, the compressor in the present invention further preferably includes being arranged on compressor crank shaft 6
Rotor 2 and the back-up ring 7 being arranged in back-up ring mounting groove 1, one end of rotor 2 and back-up ring 7
Contact.The end of compressor crank shaft 6 is then provided with back-up ring 9 and screw 10, therefore, it can
Rotor 2 is positioned by back-up ring 7 and back-up ring 9.
Preferably, back-up ring 7 is C-shaped, it is highly preferred that the A/F of back-up ring 7 is less than back-up ring
The internal diameter of mounting groove 1.During use, by this opening, back-up ring 7 can be snapped in back-up ring mounting groove 1
In.Use the back-up ring 7 of this shape, can easily back-up ring 7 be carried out the behaviour such as installation and removal
Make, improve work efficiency.
Certainly, it is above the preferred embodiment of the present invention.It should be pointed out that, and this technology is led
For the those of ordinary skill in territory, on the premise of without departing from its general principles, it is also possible to
Making some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
