Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, and in particular to a DC motor with ceramic heat insulation. Background Technology
[0002] A DC motor is a device that can convert DC electrical energy into mechanical energy or vice versa. When it operates as an electric motor, it converts electrical energy into mechanical energy to drive various mechanical equipment. When it operates as a generator, it converts mechanical energy into electrical energy to supply the power grid or other electrical equipment. The motor housing is the main heat insulation and protection structure, which can prevent external environmental factors such as dust and moisture from corroding the internal components, thereby maintaining the normal operation of the motor.
[0003] Motors operating in high-temperature environments, such as industrial furnaces and metallurgical equipment, experience greater thermal stress on their internal mechanical components, such as bearings and gears. This leads to poorer heat dissipation, causing the internal temperature of the motor to rise, increasing copper and iron losses and reducing motor efficiency. High temperatures also reduce the motor's speed and output power, further impacting the overall performance of the equipment. Utility Model Content

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0019] Please see Figure 1-4 This utility model provides a technical solution:
[0020] A DC motor with ceramic heat insulation includes a motor body 1. A heat insulation component 2 is sleeved on the outside of the motor body 1. The heat insulation component 2 includes a heat insulation cylinder 21. The heat insulation cylinder 21 is provided with a receiving cavity for placing the motor body 1. A fixing cover 23 is threaded on the front end of the heat insulation cylinder 21. A connecting groove 231 is opened in the middle of the fixing cover 23. Mounting seats 24 are symmetrically installed on the upper surface of the fixing cover 23. Support components 3 are inserted and installed on both sides of the fixing cover 23. Fixing components 4 are fixedly installed on the upper surface of the mounting seats 24.
[0021] In this embodiment, a heat insulation cylinder 21 is installed outside the motor body 1 of the DC motor. The heat insulation cylinder 21 is made of ceramic material, which can effectively isolate the heat transfer between the motor and the external environment due to its excellent heat insulation performance and high temperature resistance. The heat insulation cylinder 21 has a receiving cavity inside for precise installation of the motor body 1. The fixing cover 23 is installed on the front end of the heat insulation cylinder 21 by threads, which can close the heat insulation cylinder 21 and fix the motor. The connecting groove 231 opened on it is for the motor output shaft to pass through, while minimizing heat loss. The mounting base 24 is symmetrically installed on the fixing cover 23 to facilitate the installation and positioning of the entire motor. The support component 3 is inserted into the fixing cover 23. The two sides of the cover 23 provide additional support and stability for the entire structure, preventing structural loosening or damage caused by vibration or external forces during operation. The fixing component 4 is fixedly installed on the upper surface of the mounting base 24, further reinforcing the entire motor structure and ensuring the stability and safety of the motor during high-speed operation. The use of the ceramic heat insulation cylinder 21 effectively solves the heat dissipation and heat insulation problems during motor operation, improving the operating efficiency and stability of the motor. Through the fine structural design and the synergistic effect of each component, the entire motor is ensured to be robust, durable, and easy to install and maintain. This design is particularly suitable for temperature-sensitive applications or applications requiring long-term stable operation.
[0022] Specifically, the support component 3 includes a slot 31, a hook 32 and a first bolt 33. The surface of the fixing cover 23 is symmetrically provided with slots 31. The hook 32 is inserted into the inside of the slot 31. The first bolt 33 is fixedly installed on one side of the hook 32. The hook 32 is interlocked with the cavity inside the slot 31.
[0023] In this embodiment, the slots 31 of the support component 3 are symmetrically formed on the surface of the fixing cover 23. To ensure a tight fit with the hooks 32, the hooks 32 can be securely inserted and fixed inside the slots 31, preventing loosening or detachment. As a key component of the support component 3, the hooks 32 are inserted into the slots 31. The design of the hooks 32 allows them to interlock with the cavities inside the slots 31. When the hooks 32 are fully inserted into the slots 31 and locked in place, they can effectively resist vibrations and impacts from all directions. By tightening... Tightening the bolts generates additional clamping force, ensuring that the hook 32 remains securely in the slot 31. When the support assembly 3 is installed on the fixing cover 23, the hook 32 must first be aligned with the slot 31 and inserted. As the hook 32 goes deeper, it will fit tightly with the cavity inside the slot 31. By tightening the first bolt 33, this connection can be further reinforced. The support assembly 3 can then provide additional support and stability for the entire DC motor, ensuring that the motor can maintain a stable working state even when running at high speed or subjected to external impact.
[0024] Specifically, the fixing component 4 includes a support base 41 and a second bolt 42. The two ends of the support base 41 are fixedly installed on the upper surface of the mounting base 24, and the second bolt 42 is bolted to the two ends of the support base 41. The top of the support base 41 is provided with a mounting groove 411, and the top end of the motor body 1 is inserted into the mounting groove 411.
[0025] In this embodiment, the support base 41 serves as the main body of the fixing component 4. Both ends of the support base 41 are securely mounted on the upper surface of the mounting base 24, ensuring that the support base 41 can stably withstand the weight and vibration from the motor body 1. The top of the support base 41 is designed with a mounting groove 411, the shape and size of which match the top of the motor body 1, allowing the motor body 1 to be precisely inserted and fixed inside the mounting groove 411. Second bolts 42 are bolted to both ends of the support base 41, further reinforcing the connection between the support base 41 and the mounting base 24. Tightening the bolts allows for... Sufficient fastening force is generated to prevent the support base 41 from loosening or shifting during motor operation. Direct installation and bolt fastening greatly improve the reliability and stability of the fixing component 4. When the motor body 1 needs to be fixed in the DC motor, first align its top end with the mounting groove 411 on the support base 41 and insert it. As the motor body 1 goes deeper, it will fit tightly with the mounting groove 411 to form a solid connection. Then, by tightening the second bolt 42, the connection between the support base 41 and the mounting base 24 can be further strengthened, thereby ensuring the stability of the motor body 1 in the fixing component 4.
[0026] Specifically, the inner wall of the heat insulation cylinder 21 is provided with a concave-convex ring 22.
[0027] In this embodiment, the design of the concave-convex ring 22 can increase the surface area of the inner wall of the heat insulation cylinder 21, thereby enhancing its ability to absorb and disperse heat. When the motor body 1 generates heat during operation, the concave-convex ring 22 can more effectively block the transfer of heat to the external environment, improve the overall heat insulation performance, enhance its structural strength, and the annular protrusion can serve as a support point to disperse the pressure of the motor body 1 on the heat insulation cylinder 21, reducing the risk of deformation or damage caused by vibration or impact.
[0028] Specifically, the support base 41 has a convex shape.
[0029] In this embodiment, the convex design of the convex support 41 gives the support 41 a larger contact area in the vertical direction, thereby enhancing the connection stability between it and the mounting base 24, helping to distribute the weight and vibration generated by the motor body 1, and reducing the risk of loosening or damage caused by stress concentration.
[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
