Description
Technical Field
The invention relates to the technical field of motor rotors, in particular to a motor rotor convenient to install.
Background
In modern society, automobiles have become one of the first-choice transportation tools for the public. The automobile industry develops rapidly, and as the automobile performance develops towards the direction of being safer, more reliable, more stable, environment-friendly and energy-saving, in order to ensure the stable operation of the automobile power assembly, a perfect execution mechanism needs to be equipped, so that each actuator with a motor is widely used for the automobile power assembly, and comprises a hydraulic actuator, a gear selecting and shifting actuator, a brake assisting force and the like.
In order to ensure the stable operation of each actuator and increasingly strict requirements on light weight and miniaturization, the stability, the volume and the efficiency of the motor are required to be higher, and the existing motor has the defects of insufficient stability, large volume, large mass and poor heat dissipation, so that the improvement is necessary.
Disclosure of Invention
The invention provides the motor rotor which is convenient to produce and manufacture, good in stability, small in quality and good in heat dissipation performance and is convenient to install; the motor solves the technical problems of poor stability, poor heat dissipation performance, large volume and large mass of the motor in the prior art.
The technical problem of the invention is solved by the following technical scheme: the utility model provides an electric motor rotor convenient to installation, includes the casing, the casing in be equipped with rotor core, rotor core includes the lamination that a plurality of stack is constituteed, rotor core's center department has seted up the mounting hole, the mounting hole is equipped with the pivot, evenly open on the outer wall of pivot has a plurality of cooperation mounting groove, pivot and mounting hole interference fit after seting up the cooperation mounting groove. The rotor structure of lamination formula can reduce the eddy current loss effectively, and then improve the efficiency of motor, increase certain radiating effect simultaneously, in using, the size of mounting hole is unanimous on the size of pivot and the rotor core, set up a plurality of cooperation mounting groove on the outer wall of pivot now, cooperation mounting groove after the dashing groove is peripheral can be protruding, cooperation mounting groove outlying highly can be higher than pivot outer wall surface, then install the pivot in the mounting hole again, utilize the interference effect that deformation produced to impress rotor core with the pivot, change the pivot model not, the stability of pivot is guaranteed under the condition of increase fixed knot structure.
Preferably, each lamination of the rotor core is provided with a plurality of annularly distributed and communicated heat dissipation through holes. The heat dissipation through holes have the function of improving the heat dissipation effect and reducing the overall weight.
Preferably, the same position on each lamination of the rotor core is provided with a mounting pin hole which can be communicated. The effect of installation pinhole is alignment when being convenient for follow-up lamination installation, guarantees that everybody after the installation every heat dissipation through-hole aligns.
Preferably, a positioning pin is arranged in the mounting pin hole. The positioning pin is convenient for installation and positioning, and can also increase the stability of the lamination structure.
Preferably, a plurality of magnetic steel mounting grooves are uniformly formed in the inner side of each lamination of the rotor core, and magnetic steel is arranged in each magnetic steel mounting groove. The magnet steel mounting groove is different from the traditional magnet steel mounting groove which is arranged on the outermost side, and the magnet steel mounting groove is arranged on one side slightly close to the inner side, so that the condition that the rotor rotates at a high speed can be ensured, and the magnet steel cannot fall off under the influence of centrifugal force.
Preferably, the number of the matching mounting grooves is 4. The quantity of cooperation mounting groove can increase or reduce according to the actual demand, the utility model discloses use 4 mounting grooves to explain as the example, 4 mounting groove symmetric distribution are in the pivot, can guarantee like this that four positions of dashing groove back pivot all with mounting hole interference fit, holistic stability is better.
Therefore, the motor rotor convenient to install has the following advantages: long service life, stable in structure, motor work efficiency is high, and the radiating effect is good.

Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
Example (b):
as shown in fig. 1 and 2 and 3 and 4 and 5, a motor rotor convenient to installation, including casing 1, install rotor core 2 in the casing 1, the transition iron core includes lamination 3 of a plurality of stack installation, mounting hole 4 has all been seted up in the center department of every lamination 3, install pivot 5 in the mounting hole 4, 4 cooperation mounting grooves 6 have evenly been seted up on the outer wall of pivot 5, pivot 5 after the notching is interference fit with mounting hole 4, the equal annular heat dissipation through-hole 7 that can communicate has been seted up in the mounting hole 4 outside on every lamination 3, the same position in the heat dissipation through-hole 7 outside of every lamination 3 has all been seted up installation pinhole 8, install locating pin 9 in the installation pinhole 8, a plurality of magnet steel 11 mounting groove 10 has evenly been seted up to every lamination 3 inboard of rotor core 2, all install magnet steel 11 in every magnet steel 11 mounting groove 10.
When in use, the rotating shaft 5 is the same as the mounting hole 4 in size, 4 evenly distributed matching mounting grooves 6 are punched on the rotating shaft 5, the peripheral height of the matching mounting grooves 6 after punching can be higher than the surface of the outer wall of the rotating shaft 5, then the rotating shaft 5 is mounted in the mounting hole 4, so that the interference fit between the rotating shaft 5 and the mounting hole 4 is realized, so that the rotating shaft 5 can be fixedly mounted on the rotor core 2 under the condition of not changing the model of the rotating shaft 5, the rotor core 2 mounted by the lamination type 3 can effectively reduce the eddy current loss, thereby effectively improving the motor efficiency, and having a certain heat dissipation effect, the magnetic steel 11 is fixed on the inner side of the rotor core 2 close to the outside, compared with the traditional method of fixing the magnetic steel 11 on the outermost side, the magnetic steel 11 can not fall off due to the centrifugal force.
