Embodiment 1

[0078] The present invention provides a support device for supporting the radial ventilation slots of the stator, such as Figure 1-2 As shown, the supporting device 10 includes a positioning component 101 and a plurality of supporting ribs 102 .

[0079] A plurality of supporting ribs 102 are arranged at intervals along the circumferential direction of the stator, and one end of the plurality of supporting ribs 102 along the axial direction of the stator is provided with a positioning assembly 101, and the positioning assembly 101 is provided with a plurality of accommodations for accommodating the supporting ribs 102. Groove 103. In other alternative embodiments, the positioning assembly 101 is not limited to be arranged at one end of the plurality of support ribs 102, and the positioning assembly 101 can be provided at both ends of the plurality of support ribs 102 along the axial direction of the stator, which can play a role The positioning effect of the accommodating gr...

Embodiment 2

[0101] The structure of this embodiment is basically the same as that of Embodiment 1, except that the number of positioning components 101 is different, the structure of positioning components 101 is different, the structure of supporting ribs 102 is different, and the number of substrates 104 is different. The same reference numerals in Example 1 refer to the same elements.

[0102] Such as Figure 4-6 As shown, along the axial direction of the stator, positioning components 101 are provided at both ends of a plurality of first supporting ribs 1021 and a plurality of second supporting ribs 1022, wherein one positioning component 101 is a first positioning component 1011, and the other positioning component Component 101 is a second positioning component 1012 . The two positioning components 101 can better limit the movement of the first support rib 1021 and the second support rib 1022 along the circumferential and radial directions of the stator, improve the stacking accura...

Embodiment 3

[0109] The structure of this embodiment is basically the same as that of Embodiment 2, the difference being that the structure of the positioning assembly 101 is different, and the same reference numerals in this embodiment and Embodiment 2 refer to the same elements.

[0110] Such as Figure 7-8 As shown, a first accommodating groove 1031 and a second accommodating groove 1032 adjacent to it are a set of accommodating grooves, and two adjacent accommodating groove groups are sequentially arranged on the first positioning assembly 1011 and the second positioning assembly 1012 Arranged alternately, it can reduce the number of accommodation grooves 103 while playing a better role of the accommodation grooves 103 in limiting the first support rib 1021 and the second support rib 1022, saving the man-hours required for forming the accommodation groove 103 . The first support rib 1021 is accommodated in the first accommodation groove 1031 , and the second support rib 1022 is accomm...

Abstract

The invention discloses a support device, a stator including the same and an assembly method of the stator core, which are used to support radial ventilation slots of the stator. The support device includes a plurality of support ribs and a positioning component. A plurality of support ribs are arranged at intervals along the circumferential direction of the stator, at least one end of the plurality of support ribs along the axial direction of the stator is provided with a positioning assembly, and a plurality of accommodating grooves for accommodating the support ribs are provided on the positioning assembly, along the stator The axial direction of the accommodating groove is towards the supporting rib, the accommodating groove is used to accommodate one end of the corresponding supporting rib, and the other end of the corresponding supporting rib is located outside the accommodating groove, and the accommodating groove is used to limit the supporting rib Movement in the circumferential and radial directions of the stator. The invention restricts the movement of the support ribs along the circumferential direction and the radial direction of the stator by directly placing the support ribs in the accommodation groove of the positioning assembly, which saves a lot of man-hours required for welding the support ribs and the base plate in the prior art, The manufacturing cost is reduced, and the stacking accuracy of the stator core is improved.

Description

technical field [0001] The invention relates to a support device, a stator including the support device, and an assembly method of the stator iron core. Background technique [0002] Forced air cooling is a commonly used cooling method for large motors, especially wind turbines. The cooling air is driven by a fan to pass through the generator to cool the internal components of the generator. Radial ventilation is one of the specific air cooling technologies. By setting multiple rows of radially penetrating ventilation slots inside the stator core or rotor core, the cooling airflow can pass through the core in the radial direction, thereby taking away the winding and Heat generated in the iron core. Radial ventilation technology greatly improves the effective heat dissipation area to a certain extent, so it is the first choice in the air cooling structure of large motors. In most cases, the silicon steel sheets are discontinuously stacked along the axial direction, and a su...
