Description
Technical field
The utility model relates to a kind of electric machine structures, more specifically to a kind of single-bearing machine.
Background technique
Motor refers to a kind of calutron that electric energy conversion or transmitting are realized according to the law of electromagnetic induction, its main function
It is to generate driving torque, as electrical appliance or the power source of various machinery.
In the structure of motor, it usually is designed with a bearing in the front and rear sides of its rotor (i.e. shaft), to reach more
Supporting role well.As shown in Figure 5,6, existing motor generally includes shell, rotor, stator, two bearings, stator, rotor, two
A bearing is separately mounted in shell, and two bearings are respectively fitted on rotor, and two bearings are located at the two sides of rotor.
The effect of the two bearings is to provide support to rotor, avoids rotor from shaking, rotor unbalance stress is avoided to deform.
But many times, after motor is mounted, the mechanism connecting with its rotor also has bearing, this makes to entire
For machine, the rotor of motor can reach identical effect in fact without two bearings, this makes the structure of motor not
It is enough reasonable, parts redundant, cost increase, and excessive support, it is possible to the connection to rotor and other mechanisms instead and generates
Adverse effect.Therefore, it for the behaviour in service of above-mentioned this purposes motor, needs reasonably to improve the structure of motor.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of single-bearing machine, this single-bearing machine can be allowed
Rotor obtains enough supports to bindiny mechanism, effectively simplifies structure, reduces production cost.The technical solution of use is such as
Under:
A kind of single-bearing machine, including shell, rotor, stator, stator, rotor are separately mounted in shell, shell both ends
It is provided with rotor mounting hole, two ends of rotor is stretched out from the rotor mounting hole at shell both ends respectively, it is characterised in that: the single-bearing
Motor further includes a bearing and the interface for installing outer connection mechanism shaft, which is mounted in shell, and the bearing
It covers on rotor, the interface is arranged on hull outside wall and interface and bearing are located at the two sides of rotor.
Preferably scheme, the shell include enclosure body, drive end bearing bracket, rear end cap, and enclosure body front end, rear end are set respectively
There is opening, drive end bearing bracket is mounted on enclosure body front opening, and rear end cap is mounted in enclosure body open rearward end.
The front side on drive end bearing bracket and being located at rotor is arranged in more optimal solution, the interface, and the bearing is located at rotor
Rear side.
Preferably scheme, the interface include at least two mounting-positioning holes, and each mounting-positioning holes are along rotor mounting hole
Circumferential direction be uniformly distributed.
Preferably scheme is equipped with motor high-voltage leading-out wire and motor low pressure lead-out wire on the rear end cap.
Preferably scheme, the single-bearing machine are permanent magnet synchronous motor.
Compared with the prior art, the utility model has the beneficial effect that being additionally arranged since a bearing is only arranged for pacifying
The interface of outer connection mechanism shaft is filled, and after interface and bearing are located at the two sides of rotor, therefore motor installs, the course of work
In, the bearing of outer connection mechanism shaft and the bearing of rotor can play good supporting role, and the structure of motor obtains
Simplify, production cost is also effectively reduced.
