Description

Technical Field

[0001] This utility model relates to a silicon steel sheet rotor structure, belonging to the technical field of silicon steel sheet rotor structure. Background Technology

[0002] Silicon steel sheet rotors are a core component widely used in motors and generators. Their structure is made of multiple layers of silicon steel sheets with high magnetic permeability and low iron loss.

[0003] Currently, the lamination connection of silicon steel sheet rotors mainly adopts bonding or welding processes. Although the cost is low and the process is mature, at high speed, due to the combined effects of centrifugal force, thermal stress and mechanical vibration, the laminations are prone to loosening or displacement.

[0004] Therefore, it is urgent to improve the structure of silicon steel sheet rotors to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a silicon steel sheet rotor structure. When the rotor is connected to one of the silicon steel sheets, the connection with one of the silicon steel sheets can be reinforced by a second positioning block. At the same time, each silicon steel sheet is positioned and stacked by a first positioning block and a positioning groove, and then welded or bonded, thereby effectively suppressing the risk of lamination loosening during high-speed operation.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a silicon steel sheet rotor structure, comprising a stator and a rotor disposed inside the stator, wherein a plurality of silicon steel sheets are stacked inside the rotor, and a plurality of second positioning blocks are fixedly disposed inside the rotor, the second positioning blocks being used for installation and limiting of the plurality of silicon steel sheets;

[0007] Multiple fixing blocks are fixedly installed on the inner side of the stator, and a heat-conducting plate is fixedly installed on the side of each fixing block near the rotor. The heat-conducting plate is used for heat dissipation.

[0008] Preferably, a plurality of connecting diagonal rods are fixedly provided on the stator, and each connecting diagonal rod is inclined in one direction.

[0009] Preferably, the silicon steel sheet has a plurality of ventilation slots, the same number as the connecting diagonal rod, and the ventilation slots are slidably connected to the connecting diagonal rod.

[0010] Preferably, each of the silicon steel sheets is fixedly provided with a first positioning block on one side, the number and position of which are the same as those of the second positioning block. The first positioning block is used for connecting and reinforcing the multiple silicon steel sheets.

[0011] Preferably, each of the first positioning blocks is provided with a positioning groove, and the width of both the positioning groove and the first positioning block gradually increases from narrow to wide.

[0012] Preferably, a rotating shaft is fixedly provided at the center point of the rotor shaft, and a through groove is provided at the center of the rotor and each of the silicon steel sheets to accommodate the connection of the rotating shaft.

[0013] This utility model has at least the following beneficial effects:

[0014] When the rotor is connected to one of the silicon steel sheets, the connection with one of the silicon steel sheets can be reinforced by the second positioning block. At the same time, each silicon steel sheet is positioned and stacked by the first positioning block and the positioning groove and then welded or bonded, thereby effectively suppressing the risk of lamination loosening during high-speed operation.

Detailed Implementation

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Examples, such as Figures 1-4As shown, a silicon steel sheet rotor structure includes a stator 1 and a rotor 2 disposed inside the stator 1. Several silicon steel sheets 3 are stacked inside the rotor 2. Several second positioning blocks 9 are fixedly disposed inside the rotor 2. The second positioning blocks 9 are used for installation and limiting of multiple silicon steel sheets 3. Each silicon steel sheet 3 has a first positioning block 5 fixedly disposed on one side with the same number and position as the second positioning blocks 9. The first positioning blocks 5 are used for connection and reinforcement of multiple silicon steel sheets 3. Each first positioning block 5 has a positioning groove 6. The width of the positioning groove 6 and the first positioning block 5 both change from narrow to wide. When the rotor 2 is connected to one of the silicon steel sheets 3, the connection with one of the silicon steel sheets 3 can be reinforced by the second positioning block 9. At the same time, each silicon steel sheet 3 is positioned and stacked by the first positioning block 5 and the positioning groove 6 and then welded or bonded, thereby effectively suppressing the risk of lamination loosening during high-speed operation.

[0024] It should be noted that the end of the first positioning block 5 that is closer to the silicon steel sheet 3 to which it is fixed is the wider end, and the end of the positioning groove 6 that is farther away from the first positioning block 5 is the wider end. The wider end of the positioning groove 6 is smaller than the wider end of the first positioning block 5, so that multiple silicon steel sheets 3 can be positioned and stacked through the first positioning block 5 and the positioning groove 6.

[0025] Multiple fixing blocks 10 are fixedly installed on the inner side of the stator 1. Each fixing block 10 is fixedly installed with a heat-conducting plate 11 on the side near the rotor 2. The heat-conducting plate 11 is used for heat dissipation. This structure can efficiently guide and evenly disperse the heat generated by the silicon steel sheet 3, thereby significantly improving the overall heat dissipation performance.

[0026] Furthermore, multiple connecting diagonal rods 8 are fixedly installed on the stator 1, each of which is inclined in one direction. Multiple ventilation slots 4, the same number as the connecting diagonal rods 8, are opened on the silicon steel sheet 3. The ventilation slots 4 are slidably connected to the connecting diagonal rods 8. The multiple connecting diagonal rods 8 are evenly distributed around the circumference, providing precise position guidance for the ventilation slots 4 opened on the outer side of the silicon steel sheet 3, so that the ventilation slots 4 after multi-layer stacking form a continuous inclined air duct structure.

[0027] It should be noted that all connecting diagonal rods 8 are arranged with a uniform inclination to ensure that the formed air duct is in a directional inclined state, thereby enhancing the airflow effect and significantly improving the forced convection heat dissipation efficiency of silicon steel sheet 3.

[0028] Furthermore, a rotating shaft 12 is fixedly installed at the center point of the rotor 2. A through groove 7 is provided at the center of the rotor 2 and each silicon steel sheet 3 to accommodate the connection of the rotating shaft 12. The opening of the through groove 7 allows the rotating shaft 12 to be connected to the rotor 2 and multiple silicon steel sheets 3 through the through groove 7.

[0029] In this embodiment, as Figures 1-4 As shown, the principle of a silicon steel sheet rotor structure provided in this embodiment is as follows:

[0030] When the rotor 2 is connected to one of the silicon steel sheets 3, the connection with one of the silicon steel sheets 3 can be reinforced by the second positioning block 9. At the same time, each silicon steel sheet 3 is positioned and stacked by the first positioning block 5 and the positioning groove 6 and then welded or bonded, thereby effectively suppressing the risk of lamination loosening during high-speed operation.

[0031] Multiple fixing blocks 10 are fixedly installed on the inner side of the stator 1. Each fixing block 10 is fixedly installed with a heat-conducting plate 11 on the side near the rotor 2. The heat-conducting plate 11 is used for heat dissipation. This structure can efficiently guide and evenly disperse the heat generated by the silicon steel sheet 3, thereby significantly improving the overall heat dissipation performance.
