Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of high temperature wear-resistant combined plastic magnetic rotor, specifically relating to a high temperature wear-resistant combined plastic magnetic rotor. Background Technology
[0002] The high-temperature wear-resistant composite plastic magnetic rotor is a core component of a motor with special properties. It employs a composite structure design, combining high-performance magnetic materials with wear-resistant engineering plastics through a specific process. This results in a rotor that combines magnetic strength with structural stability. The rotor improves electromagnetic conversion efficiency through optimized magnetic circuit distribution. Furthermore, the use of a high-temperature resistant resin matrix and reinforcing fiber materials allows it to operate stably for extended periods in environments exceeding 150°C. The surface is treated with a wear-resistant coating or uses a self-lubricating formula, effectively reducing frictional losses with components such as the stator and bearings during high-speed rotation and extending service life. The composite structure design also allows for flexible adjustment of the magnet arrangement and overall dimensions to suit different motor specifications. It is suitable for applications requiring stringent high-temperature and wear-resistant performance, such as drive motors for new energy vehicles and industrial servo motors, providing crucial support for high-reliability power systems.
[0003] When high-temperature wear-resistant composite plastic magnetic rotors are in use, friction occurs between easily worn parts such as the internal components of the magnets, leading to component wear. Therefore, the market needs a new device to solve the current problem. Utility Model Content

Therefore, the market needs a new device to solve the current problems.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature wear-resistant combined plastic magnetic rotor, comprising a magnet, a rotor core disposed inside the magnet, and a rubber gasket installed between the magnet and the rotor core. Multiple protrusions are distributed on the inner wall of the rubber gasket. Bearings are disposed at the middle of the left and right ends of the magnet. A rotating shaft is disposed inside the magnet, with a shaft head at the front end of the rotating shaft. A groove is disposed inside the front end of the rotating shaft, and a flow channel is disposed inside the groove. A plug is installed at the front end of the flow channel. The flow channel leads to a storage compartment located inside the rotating shaft. Multiple small flow mesh holes are distributed on the outer wall of the storage compartment, coinciding with a through groove inside the rotating shaft. A sponge is disposed inside the through groove.
[0006] Preferably, end caps are installed at both ends of the magnet, and multiple grooves are distributed inside the end caps.
[0007] Preferably, the bearing is located inside the end cover and supports the rotating shaft.
[0008] Preferably, the rotating shaft is located inside the magnet and is used to transmit torque to drive the external load to rotate.
[0009] Preferably, a winding is provided inside the magnet, the winding being a copper coil, which generates electromagnetic induction when current flows through it.

[0013] Compared with the prior art, this utility model provides a high-temperature wear-resistant composite plastic magnetic rotor, which has the following beneficial effects:
[0014] 1. When using this device, open the plug and add lubricating oil into the flow pipe. The lubricating oil flows into the storage tank through the flow pipe. The small flow mesh on the outer wall of the storage tank allows the lubricating oil to flow slowly outwards. The lubricating oil then flows into the passageway and soaks into the sponge. The sponge contacts the internal components of the magnet, applying the lubricating oil to its inner wall, thus reducing wear on the components.

The outer and inner walls of the rubber pad are in contact with the magnet and the rotor core, respectively, and the protrusions on the inner wall of the rubber pad are in close contact with the rotor core. The rubber pad can absorb vibration and reduce hard contact between the rotor core and the magnet. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] The utility model provides, for example Figure 1-4The high-temperature wear-resistant combined plastic magnetic rotor shown includes a magnet 1, a rotor core 11 located inside the magnet 1, and a rubber gasket 12 installed between the magnet 1 and the rotor core 11. Multiple protrusions 13 are distributed on the inner wall of the rubber gasket 12. Bearings 3 are located at the middle of the left and right ends of the magnet 1. A rotating shaft 4 is located inside the magnet 1, with a shaft head 14 at its front end. A groove 5 is located inside the front end of the rotating shaft 4, and a flow channel 7 is located inside the groove 5. A plug 6 is installed at the front end of the flow channel 7, which leads to a storage slot 8 located inside the rotating shaft 4. Multiple small flow mesh holes 9 are distributed on the outer wall of the storage slot 8, coinciding with a through groove 15 inside the rotating shaft 4. A sponge 10 is located inside the through groove 15.
[0025] When current passes through the copper coil, according to Ampere's law, the copper coil generates a magnetic field. At this time, the magnetic field generated by the copper coil interacts with the permanent magnet magnetic field generated by the magnet 1. The interaction of the two magnetic fields generates electromagnetic torque. According to the left-hand rule, this torque will cause the rotor core 11 and the shaft 4 fixed to it to start rotating. As the rotor rotates, the current phase sequence is controlled by a commutation device such as the commutator in a DC motor or the frequency converter in an AC motor to continuously change the direction of the current in the winding, so that the direction of the electromagnetic torque remains unchanged, thereby allowing the rotor to rotate continuously and stably. The mechanical energy is output through the shaft 4 to drive the external load.
[0026] like Figure 1 and Figure 4 As shown, end caps 2 are installed at both ends of the magnet 1. Multiple grooves are distributed inside the end caps 2. Bearings 3 are located inside the end caps 2 and support the rotating shaft 4. The rotating shaft 4 leads to the inside of the magnet 1 and is used to transmit torque to drive the external load to rotate. A winding is provided inside the magnet 1. The winding is a copper coil that generates electromagnetic induction when current passes through it. A rubber gasket 12 is located between the magnet 1 and the rotor core 11. A protrusion 13 is tightly attached to the outer wall of the rotor core 11. A plug 6 is connected to a flow pipe 7 through a threaded structure. The flow pipe 7 leads to a storage slot 8. A small flow mesh 9 fits into a through slot 15. A sponge 10 is located inside the through slot 15.
[0027] The outer and inner walls of the rubber pad 12 are in contact with the magnet 1 and the rotor core 11, respectively, and the protrusion 13 on the inner wall of the rubber pad 12 is in close contact with the rotor core 11. The rubber pad 12 can absorb vibration and reduce the hard contact between the rotor core 11 and the magnet 1.
[0028] 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 embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
