Abstract
The utility model discloses a motor with a rotor shaft consisting of different materials. The motor comprises a shell as well as a rotor and a stator in the shell, wherein the rotor shaft of the rotor comprises a rear shaft and a front shaft; the rear shaft penetrates through the front end of the rotor from the rear end of the rotor; the front end of the front shaft extends out of the shell, and the rear end of the front shaft is connected with the front end of the rear shaft; the joint between the rear end of the front shaft and the front end of the rear shaft is arranged on the front side of the front end surface of the rotor and is close to the front end surface; the rear shaft is a steel shaft, and the front shaft is a stainless steel shaft. The motor is simple in structure and convenient to use; the rotor shaft comprises the rear shaft and the front shaft; the rear shaft can be kept good in electromagnetic performance, and the front shaft can be prevented from being corroded and rusted, so that the problem of the damage on the motor due to rustiness of the rotor shaft is avoided.
Description
Technical field
The utility model relates to motor, relates in particular to a kind of motor of the rotor shaft with different materials composition.
Background technique
Motor is a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction.Its Main Function is to produce driving torque, as the power source of electric consumer or various machineries.
The rotor shaft of conventional motors is made by Steel material, and it just gets rusty possibly under the specific environment such as outdoor, chemical industry operating mode, and motor is damaged.
Summary of the invention
Based on this, for above-mentioned technical problem, provide a kind of motor of the rotor shaft with different materials composition.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of motor of the rotor shaft with different materials composition, comprise shell and be located at rotor and the stator in described shell, the rotor shaft of described rotor comprises back segment axle and leading portion axle, described back segment axle penetrates the front end to this rotor from the rear end of described rotor, the front end of described leading portion axle stretches in outside described shell, its rear end is connected with the front end of described back segment axle, both joints are positioned at the front side of the front-end face of described rotor, and approach described front-end face, described back segment axle is steel axle, and described leading portion axle is stainless steel shaft.
Described back segment axle is No. 45 steel axles.
Described leading portion axle is No. 304 stainless steel shafts.
The utility model is simple in structure, easy to use, and rotor shaft is made up of back segment axle and leading portion axle, and back segment axle can keep the superperformance of electromagnetism, and leading portion axle can prevent corrosion and get rusty, thus the problem of having avoided motor to damage because rotor shaft gets rusty.
Brief description of the drawings
Be elaborated below in conjunction with the drawings and specific embodiments the utility model:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of motor of the rotor shaft with different materials composition, comprises shell 110, rotor 120 and stator 130, and rotor 120 and stator 130 are located in shell 110.
The rotor shaft 121 of rotor 120 comprises back segment axle 121a and leading portion axle 121b.
Back segment axle 121a penetrates to the front end of this rotor 120 from the rear end of rotor 120.
The front end of leading portion axle 121b stretches in outside shell 110, and its rear end is connected by friction welding with the front end of back segment axle 121a, and both joints are positioned at the front side of the front-end face of rotor 120, and approach front-end face.
Wherein, back segment axle 121a is steel axle, can keep the superperformance of electromagnetism, and leading portion axle 121b is stainless steel shaft, can prevent corrosion and get rusty.
Particularly, back segment axle 121a is No. 45 steel axles, and leading portion axle 121b is No. 304 stainless steel shafts, and certainly, back segment axle 121a can be also the steel axle of other models, and same, leading portion axle 121b can be also the stainless steel shaft of other models.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, variation, modification to the above embodiment all will drop within the scope of claims of the present utility model.
