Technical Field
[0001] This utility model belongs to the field of rotor core technology, and particularly relates to a combined rotor core. Background Technology
[0002] Rotors are common rotating components in mechanical engineering and are widely used in equipment such as motors and turbines. A rotor is a rotating body supported by bearings and usually refers to the rotating part of a motor or certain rotating machines.
[0003] The rotor cores currently available on the market have the following problems when used:
[0004] 1. Traditional rotor cores are generally composed of multiple iron sheets. When transporting rotor cores, it is difficult to fix the large number of iron sheets, which can easily cause them to scatter during transportation, making them inconvenient to transport.
[0005] 2. When traditional rotor cores are idle, because they are made of metal, they are prone to oxidation and rust after being left for a long time. Once rusted, they are difficult to continue using, which easily leads to waste, and their rust prevention effect is poor. Utility Model Content

[0028] To better understand the purpose, structure, and function of this utility model, a combined rotor core of this utility model will be described in further detail below with reference to the accompanying drawings.
[0029] like Figure 1-5 As shown, this utility model discloses a combined rotor core, comprising a rotor body 1, with an insert rod 11 inserted inside the rotor body 1. One end of the insert rod 11 is fixedly connected to a baffle 21, and the other end is fixedly connected to a first disc 6. A second disc 7 is sleeved on the outside of the insert rod 11. A first strip plate 8 is fixedly connected to the side of the baffle 21, and a second strip plate 10 is fixedly connected to the side of the baffle 21. A lead screw 20 passes through the inside of the second strip plate 10, and an internal thread seat 18 is fixedly connected to the surface of the second strip plate 10. A turntable 15 is provided at the bottom of the lead screw 20, and a threaded rod 22 is fixedly connected to the surface of the first disc 6. By inserting the insert rod 11 inside the rotor body 1, installing a baffle 21 at one end of the insert rod 11, and installing the first disc 6 at the other end of the insert rod 11, the rotor core is constructed as follows: The second disc 7 is fitted with a first strip plate 8 installed on the side of the baffle 21, and the second strip plate 10 is installed on the side of the baffle 21. The second strip plate 10 has a threaded rod 20 running through it, and an internal thread seat 18 is installed on the surface of the second strip plate 10. A turntable 15 is added to the bottom of the threaded rod 20. When transporting the rotor core, the insertion rod 11 is inserted into the inside of the rotor body 1, and then the threaded rod 22 on the surface of the second disc 7 is inserted into the tail of the insertion rod 11 and tightened. At this time, the threaded rod 20 can be rotated. The threaded rod 20 rotates inside the internal thread seat 18, driving the second disc 7 to move, so that the first disc 6 and the second disc 7 clamp the rotor. At this time, it can be transported to prevent it from falling apart during transportation and to make it more stable.
[0030] A first protective cover 2 is fitted onto the outside of the rotor body 1, and a second protective cover 3 is fitted onto the outside of the rotor body 1. A first fixing block 4 is fixedly connected to the side of the first protective cover 2, and a second fixing block 5 is fixedly connected to the side of the second protective cover 3. Sealing gaskets 13 are embedded inside the first and second protective covers 2 and 3. When the rotor body 1 is not in use, the first and second protective covers 2 and 3 are fitted onto the outside of the rotor body 1 and fixed together by the first fixing block 4 and the second fixing block 5. At this time, the sealing gaskets 13 inside the first and second protective covers 2 and 3 play a sealing role, isolating the rotor body 1 from the external environment, preventing it from rusting, and improving its rust prevention effect.
[0031] One end of the lead screw 20 is fixedly connected to the handle 19, which is circular in shape. By installing a handle 12 at one end of the lead screw 20, the lead screw 20 can be easily rotated by holding the handle 19.
[0032] The guide rod 9 is fixedly connected to the surface of the second disk 7, and the top of the guide rod 9 is fixedly connected to the limiting plate 14. By installing the guide rod 9 on the surface of the second disk 7, the second disk 7 can be prevented from rotating when moving.
[0033] The first fixing block 4 has a slot 16 on its side, and the second fixing block 5 has a fixed connection to the slot 17 on its side. The slot 17 is embedded in the slot 16. By opening the slot 16 on the side of the first fixing block 4 and installing the slot 17 on the side of the second fixing block 5, the first protective cover 2 and the second protective cover 3 can be fixed together by embedding the slot 17 in the slot 16.
[0034] Handles 12 are fixedly connected to the sides of the first protective cover 2 and the second protective cover 3. There are two handles 12. By installing handles 12 on the sides of the first protective cover 2 and the second protective cover 3, the first protective cover 2 and the second protective cover 3 can be easily opened by holding the handles 12.
[0035] The working principle of this modular rotor core is as follows: When the rotor core is needed, several iron sheets are assembled together, and then the shaft is inserted into it for use. When the rotor core needs to be transported, the insert rod 11 is inserted into the inside of the rotor body 1, and then the threaded rod 22 on the surface of the second disc 7 is inserted into the tail of the insert rod 11 and tightened. At this time, the handle 19 can be held to rotate the screw 20. The screw 20 rotates inside the internal thread seat 18, driving the second disc 7 to move. The guide rod 9 can prevent the second disc 7 from rotating during movement, thus ensuring that the second disc 7... The rotor is clamped by a disc 6 and a second disc 7, and transportation can begin at this point to prevent it from scattering during transportation. When the rotor body 1 is not in use, the first protective cover 2 and the second protective cover 3 are fitted onto the outside of the rotor body 1, and the locking block 17 is embedded in the slot 16 to fix the first protective cover 2 and the second protective cover 3 together. At this time, the sealing gasket 13 inside the first protective cover 2 and the second protective cover 3 plays a sealing role, which isolates the rotor body 1 from the external environment, prevents it from rusting, and makes its rust prevention effect better.
