Abstract
The utility model relates to the technical field of motors, in particular to a motor rotor with a key groove, which comprises a motor spindle and a rotor core fixed on the motor spindle. The key groove is arranged at the front end of the motor spindle. According to the motor rotor with the key groove, the section of the key groove of the motor spindle is designed into a circular arc shape, and the motor rotor with the key groove is made of stainless steel materials, thereby the intensity of the motor spindle is effectively improved, the stress concentration of the motor spindle is reduced, and the service life of the motor spindle is prolonged.
Description
Technical field
The utility model relates to technical field of motors, especially a kind of rotor with keyway.
Background technology
Being installed in motor on the automobile or in the battery vehicle all need connect roller and come transferring power on machine shaft; The quality of machine shaft OK and machine shaft and roller between whether rationally cooperate safety; These all have influence on motor the power of automobile or electric motor car are provided, and what traditional motor shaft adopted mostly is the 45# steel, and the cross section of keyway also is a rectangular configuration; Such motor shaft deforms after long-time the rotation easily; Influence the output of power, and the keyway of square-section also causes the phenomenon that stress is concentrated easily, shorten the useful life of motor greatly.
The utility model content
The technical problem that the utility model will solve is: a kind of rotor with keyway is provided, increases the intensity of motor shaft, and reduce the phenomenon that stress is concentrated, prolong the useful life of motor.
The utility model solves the technical scheme that its technical problem adopted: a kind of rotor with keyway comprises machine shaft and is fixed on the rotor core on the machine shaft that the front end of machine shaft is provided with keyway.
Furtherly, Keyway Section is a circular arc.
Furtherly, machine shaft is a stainless steel.
The beneficial effect of the utility model is: through the Cross section Design of armature keyway is in the arc-shaped, and adopt stainless steel to process, effectively improve the intensity of machine shaft, reduce the stress of machine shaft and concentrate, prolong the useful life of machine shaft.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the schematic cross-section of keyway.
Wherein: 1. machine shaft, 2. rotor core, 3. keyway.
Embodiment
Combine accompanying drawing that the utility model is further described now.The sketch map that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of rotor with keyway as shown in Figure 1 comprises machine shaft 1 and is fixed on the rotor core 2 on the machine shaft 1 that the front end of machine shaft 1 is provided with keyway 3.Keyway 3 cross sections are circular arc.Machine shaft 1 is a stainless steel.
The Cross section Design of the keyway 3 of machine shaft 1 as shown in Figure 2 is in the arc-shaped, and adopts stainless steel to process, and effectively improves the intensity of machine shaft 1, reduces the stress of machine shaft 1 and concentrates, and prolongs the useful life of machine shaft 1.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
