Description

Technical Field

[0001] This utility model relates to the field of motor rotor technology, and in particular to a novel rotor core for motors. Background Technology

[0002] The motor rotor core is the core component of the motor rotor. It is usually made of stacked silicon steel sheets to reduce eddy current losses. Its main function is to support the rotor windings, conduct magnetic flux, and generate electromagnetic torque, thereby realizing the conversion of electrical energy into mechanical energy.

[0003] The rotor core is made of multiple silicon steel sheets stacked together. In order to ensure the overall strength of the rotor core when it rotates at high speed after stacking, end plates need to be installed at both ends of the core to increase the overall structural strength. However, at present, the end plates of most rotor cores are fixed together with the core body. Once the internal core is damaged, the end plates need to be replaced together, which greatly increases the replacement cost and reduces the overall practicality of the rotor core.

[0004] Therefore, those skilled in the art have provided a novel rotor core for electric motors to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel rotor core for motors. The device determines whether the rotor core can be inserted after rotation by aligning the arc-shaped slots of multiple connecting rods on the first end plate with the edges of corresponding arc-shaped pins on the second end plate. After confirmation, the arc-shaped pins on the second end plate are rotated and inserted into the arc-shaped slots. Once inserted, bolts are aligned with the openings on the second end plate and threaded into the first and second threaded holes, ultimately securing the first and second end plates and the core body in the middle. The disassembly process is the reverse, reducing replacement costs and improving the practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A novel rotor core for an electric motor includes a fixing mechanism and a core body. The fixing mechanism has fixing mechanisms at both ends of the core body. Each fixing mechanism includes a first end plate. A first clamping plate is fixedly connected to the edge of one side of the first end plate. A first shaft hole is formed in the middle of one side of the first end plate. Multiple connecting rods are fixedly connected around the perimeter of one side of the first end plate. Each of the multiple connecting rods has a first threaded hole at one end and an insertion hole on one side of the outer wall of each of the multiple connecting rods. A second end plate is provided at one end of each of the multiple connecting rods. A second shaft hole is formed in the middle of one side of the second end plate. Arc-shaped pins are fixedly connected around the perimeter of one side of the second end plate. Each of the multiple arc-shaped pins has a second threaded hole at one end of one side of its end face. A second clamping plate is fixedly connected to the edge of one side of the second end plate. Bolts are threadedly connected around the perimeter of one side of the second end plate.

[0008] Through the above technical solution, the device determines whether the rods can be inserted after rotation by aligning the arc-shaped slots of multiple connecting rods on the first end plate with the edges of the corresponding arc-shaped pins on the second end plate. After confirmation, the second end plate is rotated to insert the arc-shaped pins into the arc-shaped slots. After insertion, the bolts are aligned with the openings of the second end plate and the first and second threaded holes are threaded together, thus securing the first and second end plates and the iron core body in the middle. The disassembly process is the reverse, which reduces replacement costs and improves the practicality of the device.

[0009] Furthermore, the core body includes multiple circular plates, each of which has a third shaft hole in the middle of one end face, an arc-shaped groove in the outer wall of each of the multiple circular plates, and a winding end fixedly connected to the outer wall of each of the multiple circular plates.

[0010] Through the above technical solution, the device uses multiple arc-shaped slots opened on the outer wall of multiple circular plates as connecting channels for connecting rods, so that multiple connecting rods can surround and fasten the outer wall of the rotor core body. When the rotor core is damaged, the first end plate and the second end plate at both ends can be removed and taken out, which reduces the replacement cost and improves the practicality of the device.

[0011] Furthermore, the diameters of the first and second shaft holes are consistent with those in the horizontal direction;

[0012] Through the above technical solution, this arrangement allows the rotating shaft to pass through the first end plate and the second end plate, so that the two are fixed on the rotating shaft.

[0013] Furthermore, the horizontal direction of the plurality of first threaded holes is consistent with the horizontal direction of the second threaded holes, and the plurality of bolts are threadedly connected to the first threaded holes and the second threaded holes;

[0014] The above technical solution makes it easy to connect the connecting rod to the second end plate as a whole with bolts.

[0015] Furthermore, all of the connecting rods are engaged with the arc-shaped pins;

[0016] The above technical solution allows the bolt to be threadedly connected to both the arc-shaped pin and the connecting rod simultaneously.

[0017] Furthermore, one side of the outer wall of each of the multiple arc-shaped slots is slidably connected to the connecting rod;

[0018] Through the above technical solution, this setting enables the arc-shaped slot to serve as a channel for connecting the first end plate to the second end plate.

[0019] Furthermore, the diameter of the third shaft hole is the same as that of the first shaft hole in the horizontal direction, and the diameter of the third shaft hole is the same as that of the second shaft hole in the horizontal direction.

[0020] Through the above technical solution, this arrangement enables the rotating shaft to pass through the first end plate, the second end plate, and the iron core body, and fix the three of them on the rotating shaft.

[0021] Furthermore, heat dissipation holes are provided on one side of each of the multiple winding ends;

[0022] Through the above technical solution, this setting allows the heat of the rotor core to be dissipated through the heat dissipation holes during operation.

[0023] This utility model has the following beneficial effects:

The device determines whether the rotor core can be inserted after rotation by aligning the arc-shaped slots of multiple connecting rods on the first end plate with the edges of the corresponding arc-shaped pins on the second end plate. After confirming that the pins are inserted, the second end plate is rotated to align the arc-shaped pins with the arc-shaped slots. After insertion, the bolts are aligned with the openings of the second end plate and threaded to connect the first and second threaded holes, thus securing the first and second end plates and the core body in the middle. The disassembly process is the reverse, which reduces replacement costs and improves the practicality of the device.

The device uses multiple arc-shaped slots on the outer wall of multiple circular plates as connecting channels for connecting rods. This allows multiple connecting rods to surround and secure the outer wall of the rotor core body.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0035] A novel rotor core for an electric motor includes a fixing mechanism 1 and a core body 2. The fixing mechanism 1 is provided at both ends of the core body 2. The fixing mechanism 1 includes a first end plate 101. A first clamping plate 102 is fixedly connected to the edge of one side end face of the first end plate 101. A first shaft hole 103 is opened in the middle of one side end face of the first end plate 101. Multiple connecting rods 104 are fixedly connected around the periphery of one side end face of the first end plate 101. A first threaded hole 105 is opened at one end of each of the multiple connecting rods 104. Insertion holes 106 are opened on one side of the outer wall of each of the multiple connecting rods 104. A second end plate 107 is provided at one end of each of the multiple connecting rods 104. A second shaft hole 108 is opened in the middle of one side end face of the second end plate 107. Arc-shaped pins 109 are fixedly connected around the periphery of one side end face of the second end plate 107. The multiple arc-shaped pins 109 have one end... Each end of the first end plate 107 has a second threaded hole 110. A second clamping plate 111 is fixedly connected to the edge of one side of the second end plate 107. Bolts 112 are threaded around the edge of one side of the second end plate 107. The device determines whether the rods can be inserted after rotation by aligning the arc-shaped slots 203 of the multiple connecting rods 104 on the first end plate 101 with the edge of the corresponding arc-shaped pins 109 on the second end plate 107. After confirmation, the second end plate 107 is rotated to insert the arc-shaped pins 109 into the arc-shaped slots 203. After insertion, the bolts 112 are aligned with the opening of the second end plate 107 and threaded to connect the first threaded hole 105 and the second threaded hole 110. Finally, the first end plate 101, the second end plate 107, and the iron core body 2 in the middle are tightened as a whole. The disassembly process is the reverse, which reduces the replacement cost and improves the practicality of the device.

[0036] Reference Figure 3-5 The iron core body 2 includes multiple circular plates 201. Each of the multiple circular plates 201 has a third shaft hole 202 in the middle of one end face. Each of the multiple circular plates 201 has an arc-shaped groove 203 around its outer wall. Each of the multiple circular plates 201 has a winding end 204 fixedly connected to its outer wall. The device uses the multiple arc-shaped grooves 203 on the outer wall of the multiple circular plates 201 as connecting channels for the connecting rods 104. This allows the multiple connecting rods 104 to surround and secure the outer wall of the rotor iron core body. When the rotor iron core is damaged, the first end plate 101 and the second end plate 107 at both ends can be removed and taken out, reducing replacement costs and improving the practicality of the device.

[0037] The diameters of the first shaft hole 103 and the second shaft hole 108 are the same in the horizontal direction. This arrangement allows the rotating shaft to pass through the first end plate 101 and the second end plate 107, so that the two are fixed on the rotating shaft.

[0038] The horizontal direction of the multiple first threaded holes 105 is consistent with the horizontal direction of the second threaded holes 110, and the multiple bolts 112 are threaded to the first threaded holes 105 and the second threaded holes 110. This arrangement makes it easy for the bolts 112 to connect the connecting rod 104 to the second end plate 107 as a whole.

[0039] Multiple connecting rods 104 are engaged with arc-shaped pins 109, which allows bolts 112 to simultaneously thread the arc-shaped pins 109 and connecting rods 104.

[0040] One side of the outer wall of the multiple arc-shaped slots 203 is slidably connected to the connecting rod 104. This arrangement allows the arc-shaped slots 203 to serve as channels for connecting the first end plate 101 to the second end plate 107.

[0041] The diameter of the third shaft hole 202 is the same as that of the first shaft hole 103 in the horizontal direction, and the diameter of the third shaft hole 202 is the same as that of the second shaft hole 108 in the horizontal direction. This arrangement allows the rotating shaft to pass through the first end plate 101, the second end plate 107, and the iron core body 2, and fix the three on the rotating shaft.

[0042] Multiple winding ends 204 are provided with heat dissipation holes 205 on one side of their end faces. This arrangement allows the heat of the rotor core to be dissipated through the heat dissipation holes 205 during operation.

[0043] Working principle: The device determines whether the connecting rods can be inserted after rotation by aligning the arc-shaped slots 203 of the multiple connecting rods 104 on the first end plate 101 with the corresponding arc-shaped pins 109 on the second end plate 107. After confirmation, the second end plate 107 is rotated to insert the arc-shaped pins 109 into the arc-shaped slots 203. After insertion, the bolts 112 are aligned with the openings of the second end plate 107 and threaded together with the first threaded hole 105 and the second threaded hole 110, thus securing the first end plate 101, the second end plate 107, and the iron core body 2 in the middle. The disassembly process is the reverse. The multiple arc-shaped slots 203 on the outer wall of the multiple circular plates 201 serve as connecting channels for the connecting rods 104, thereby securing the outer wall of the rotor iron core body with the multiple connecting rods 104. When the rotor iron core is damaged, the first end plate 101 and the second end plate 107 at both ends can be removed for extraction.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features.
