Detailed description of the invention
With specific embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings, but not as to this practicality
Novel restriction.
As shown in Fig. 4 to Fig. 9, this utility model embodiment provides a kind of compressor crank shaft, and it is particularly well-suited to miniature pressure
Contracting machine uses.
As shown in Figure 4 and Figure 5, this compressor crank shaft includes that axis body, axis body include the some such as shaft part A.Wherein, at axle
Being formed with a back-up ring mounting groove 1 on section A, shaft part A is divided into two parts by this back-up ring mounting groove 1, is i.e. used for installing rotor 2
Rotor section 3 and the first shaft part 4, rotor section 3 lays respectively at the both sides of back-up ring mounting groove 1, and rotor section 3 with the first shaft part 4
Identical with the diameter of axle of the first shaft part 4.Therefore, the compressor crank shaft in this utility model does not use Step-edge Junction of the prior art
Rotor 2 is axially positioned by structure.
During installation, a back-up ring 7 as shown in Figure 5 can be set in back-up ring mounting groove 1, say, that back-up ring 7 is stuck in this
In back-up ring mounting groove 1.So, after rotor 2 is installed on rotor section 3, so that it may utilize back-up ring 7 axially carrying out calmly rotor 2
Position, without arranging ledge structure of the prior art, 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 this utility model back-up ring 7 both sides will not change, i.e.
Ledge structure will not be produced so that the minimum diameter of bent axle is bigger than diameter of the prior art, thus it is bent to improve compressor
The intensity of axle, is also no longer necessary to it is carried out step grinding processing, improves the manufacturability of processing, reduce compressor crank shaft
Difficulty of processing and cost, have simple in construction, easy to process, the feature of low cost.
Circumferentially positioned in order to realize rotor 2, this utility model also can be formed on rotor section 3 one or more for
The trimming 5 that rotor 2 is axially positioned.Such as, in the embodiment shown in Fig. 6 and Fig. 7, can be as using in the prior art
One trimming；And in the embodiment shown in fig. 8, the number of trimming 5 can also be two, and the two trimming 5 relative tilt
Ground is arranged.It is further preferable that the angle between the two trimming 5 is 5 to 10 degree, in case wrongly installed direction during spline son 2 assembling.
In a particularly preferred embodiment, the compressor crank shaft in this utility model is in use, it is also possible to do not make
With back-up ring 7, now owing to having two trimmings, position having at two, thus without the situation producing rotor discontinuity equalization.
As shown in Figure 10, this utility model additionally provides a kind of compressor, including above-mentioned compressor crank shaft 6.Such as Figure 10,
The compressor crank shaft of this compressor can realize the axle of rotor by the back-up ring being arranged in the back-up ring mounting groove 1 of compressor crank shaft 6
To location, it is therefore not necessary to use ledge structure of the prior art, not only increase the intensity of compressor crank shaft, the most no longer need
It carried out step grinding processing, to improve the manufacturability of processing, reduce difficulty of processing and the cost of compressor crank shaft.
Such as Figure 10, the compressor in this utility model further preferably include the rotor 2 that is arranged on compressor crank shaft 6 and
The back-up ring 7 being arranged in back-up ring mounting groove 1, one end of rotor 2 contacts with back-up ring 7.The end of compressor crank shaft 6 is then provided with
Back-up ring 9 and screw 10, therefore, it can be positioned rotor 2 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 the internal diameter of back-up ring mounting groove 1.Use
Time, by this opening, back-up ring 7 can be snapped in back-up ring mounting groove 1.Use the back-up ring 7 of this shape, can be easily to back-up ring 7
Carry out the operations such as installation and removal, improve work efficiency.
Certainly, it is above preferred implementation of the present utility model.It should be pointed out that, the ordinary skill for the art
For personnel, on the premise of without departing from this utility model ultimate principle, it is also possible to make some improvements and modifications, these improve
It is also considered as protection domain of the present utility model with retouching.
