Description

Technical Field

[0001] The utility model relates to the technical field of stator cores, in particular to a spliced stator core. Background Technique

[0002] The stator is the stationary part of the motor. The stator is composed of three parts: the stator core, the stator winding and the frame. Among them, the stator core is an important part of the magnetic circuit of the motor. It, together with the rotor core and the air gap between the stator and the rotor, forms the complete magnetic circuit of the motor. In an asynchronous motor, the magnetic flux in the stator core is alternating, thus generating core loss.

[0003] Most of the existing stator cores are formed by laminating multiple cold-rolled steels. It is not easy to align and splice them. When the rotational speed is too high during use, the stator core will be scattered and separated, thereby reducing the stability of use. And after being damaged, the whole stator core needs to be replaced, increasing the production cost. Summary of the Invention

[0004] The purpose of the utility model is to provide a spliced stator core to solve the problems that the existing stator core is not convenient for aligning and splicing installation and is not convenient for individual disassembly and replacement mentioned in the above background technique. To achieve the above purpose, the utility model provides the following technical scheme: A spliced stator core includes stator core blocks. One end of the stator core block is fixed with a T-shaped tenon block, and the other end of the T-shaped tenon block is provided with a T-shaped tenon groove. The outer wall of the stator core block is sleeved with a detachable stator outer frame, and detachable gaskets are arranged on both sides of the stator outer frame.

[0005] Preferably, there are multiple stator core blocks. T-shaped tenon grooves are arranged on one side of each of the multiple stator core blocks, and T-shaped tenon blocks are installed on the other side of each of the multiple stator core blocks. The T-shaped tenon blocks are tenoned with the T-shaped tenon grooves.

[0006] Preferably, the inner wall of the stator outer frame is provided with a clamping groove, and a clamping plate is fixed on the outer wall of the stator core block. The clamping plate is clamped with the clamping groove.

[0007] Preferably, annular grooves are arranged on both sides of the stator outer frame.

[0008] Preferably, annular clamping strips are fixed at both ends of the gasket. The annular clamping strips are clamped with the annular grooves.

[0009] Preferably, a clamping ring is fixedly sleeved on the outer circumference of the gasket. A through hole is opened inside the clamping ring, and a screw penetrates through the inside of the through hole. A nut is threadedly sleeved on the outside of the screw.

[0010] Preferably, there are two gaskets, and the two gaskets are symmetrically arranged about the axis of the stator outer frame.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, a plurality of stator core blocks are provided. The stator core blocks are assembled by mortise and tenon, and a reinforcement structure is installed outside them, making the overall structure of the spliced stator core firm and reliable, and improving the use effect.

[0013] In the present utility model, when a certain stator core block is damaged, the above steps can be reversed to disassemble and replace it, greatly improving the utilization of materials and work efficiency, and saving labor and material costs. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a spliced stator core, including a stator core block 1, one end of the stator core block 1 is fixed with a T-shaped tenon block 2, and the other end of the T-shaped tenon block 2 is provided with a T-shaped tenon groove 3. The outer wall of the stator core block 1 is sleeved with a detachable stator outer frame 5, and detachable gaskets 6 are provided on both sides of the stator outer frame 5.

[0028] In this embodiment, as Figure 3 and Figure 4 shown, there are multiple stator core blocks 1. T-shaped tenon grooves 3 are provided on one side of the multiple stator core blocks 1, and T-shaped tenon blocks 2 are installed on the other side of the multiple stator core blocks 1. The T-shaped tenon blocks 2 are tenoned with the T-shaped tenon grooves 3.

[0029] It should be noted that the multiple stator core blocks 1 are tenoned together through the T-shaped tenon grooves 3 and the T-shaped tenon blocks 2, so that the multiple stator core blocks 1 are assembled into a circular stator core.

[0030] In this embodiment, as Figure 4 and Figure 5 shown, a clamping groove 51 is provided on the inner wall of the stator outer frame 5, and a clamping plate 4 is fixed on the outer wall of the stator core block 1. The clamping plate 4 is clamped with the clamping groove 51.

[0031] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, annular grooves 52 are provided on both sides of the stator outer frame 5.

[0032] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, annular clamping strips 61 are fixed at both ends of the gasket 6. The annular clamping strips 61 are clamped with the annular grooves 52.

[0033] It should be noted that the annular clamping strips 61 are placed inside the annular clamping plate 4, so that the gaskets 6 are respectively clamped at both ends of the assembled stator core blocks 1 for processing, so that the assembled stator core will not be separated during use, improving the stability of use.

[0034] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, a snap ring 62 is fixedly sleeved on the outer periphery of the gasket 6. A through hole 63 is provided inside the snap ring 62, a screw 64 penetrates through the inside of the through hole 63, and a nut 65 is threadedly sleeved on the outside of the screw 64.

[0035] In this embodiment, as Figure 1 , Figure 2 , Figure 3 andFigure 5 As shown, there are two gaskets 6, and the two gaskets 6 are symmetrically arranged about the axis of the stator outer frame 5.

[0036] It should be noted that the gasket 6 is installed at both ends of the stator outer frame 5. At the same time, a snap ring 62 is installed outside the gasket 6, and a through hole 63 is opened inside the snap ring 62. The screw 64 passes through the through holes 63 of the two snap rings 62, and the rotating nut 65 rotates and slides along the top of the screw 64 to the side wall of the snap ring 62, so as to fix the two snap rings 62 together.

[0037] The usage method and advantages of the present utility model: When the split stator core works, the working process is as follows:

[0038] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when splicing the stator core, first splice multiple stator core blocks 1. The T-shaped tenon block 2 on the end side of one stator core block 1 is inserted into the T-shaped mortise groove 3 on the end side of another stator core block 1 to form a tenon joint. And so on, it is spliced into an annular shape to form a stator core by the tenon and mortise method. Subsequently, the card slot 51 of the stator outer frame 5 is aligned with the card plate 4 and pressed, so that the stator outer frame 5 is quickly spliced on the outer periphery of the spliced stator core blocks 1 for preliminary fixation. Immediately, two gaskets 6 are respectively installed at both ends of the stator core blocks 1, and the annular card strips 61 on their end sides are inserted into the annular grooves 52 on both sides of the stator outer frame 5. Subsequently, the screw 64 passes through the through holes 63 in the two snap rings 62, and the rotating nut 65 rotates and slides along the top of the screw 64 to the side wall of the snap ring 62, so as to fix the two snap rings 62 together, making the overall structure of the spliced stator core firm and reliable, improving the use effect. When a certain stator core block 1 is damaged, the above steps can be reversed to disassemble and replace it, greatly improving the utilization of materials and work efficiency, and saving labor and material costs.
