Description
Technical Field
[0001] This utility model relates to the field of electric motor technology, and in particular to a novel motor end cover for preventing copper wires from being thrown out. Background Technology
[0002] The emergence of motor end covers is the result of the combined effect of motor structural design and functional requirements. Their existence stems from a comprehensive consideration of motor operation safety, stability, and practicality. As an important component of the motor housing, motor end covers can seal the openings at both ends of the motor to form a physical barrier, preventing external dust, moisture, and other impurities from entering the interior. At the same time, they prevent internal copper wires, lubricating oil, etc. from leaking out, ensuring a clean and stable internal environment. Through rigid connection with the frame and bearing housing, they provide stable support for rotating components such as bearings and shafts, ensuring coaxiality and stability during high-speed operation, reducing friction, abnormal noise, or damage caused by shaking, and improving mechanical strength and reliability. In addition, some end covers also have auxiliary heat dissipation functions, dissipating heat through heat dissipation fins or in conjunction with a fan. The reserved mounting holes and positioning structures facilitate the connection and fixation of the motor with the equipment frame and transmission components, making them key structural components that ensure the long-term stable operation of the motor.
[0003] The structure of the motor end cover revolves around its protective, supportive, and assembly functions. It is usually based on a rigid shell, often made of cast iron, aluminum alloy, or other materials through casting or stamping to ensure structural strength and sealing. The core part includes a flange that connects to the motor frame, which is rigidly fixed to the frame through bolt holes. The inner side has a bearing chamber for precise installation and fixation of the bearing, providing rotational support for the shaft and ensuring coaxiality. Some end covers are designed with auxiliary structures according to functional requirements, such as heat dissipation fins on the outside to enhance heat dissipation efficiency, or reserved installation interfaces for use with fans and protective covers. The inner side can be equipped with positioning protrusions or sealing grooves to improve the fitting accuracy with internal motor components and dustproof and waterproof performance. The overall structure takes into account both practicality and stability and is a key node in the overall assembly of the motor.
[0004] When existing motors operate at high speeds or vibrate, the copper wires tend to detach from their original positions and fly outwards, rubbing and colliding with components such as end covers and shafts. This damages the insulation layer of the copper wires, leading to short circuits, leakage, and other circuit faults, seriously threatening the motor's operational safety. The detached copper wires can also loosen the internal structure, disrupting the stable fit of components such as windings and cores, exacerbating mechanical wear and abnormal noise, and shortening the motor's lifespan. Furthermore, exposed copper wires cause abnormally high energy consumption during motor operation, and frequent shutdowns for maintenance after malfunctions are required. This not only increases maintenance costs but also reduces production efficiency due to equipment downtime, affecting the overall stability and economy of operation. Therefore, a new type of motor end cover to prevent copper wires from flying out is proposed to solve the above problems. Utility Model Content

[0008] The reinforcement mechanism includes two arc-shaped shells, the inner sides of which are slidably connected to the outer side of the end cap bottom. The two arc-shaped shells are rotatably connected to a rotating shaft. An auxiliary block is fixedly connected to the end of each arc-shaped shell away from the rotating shaft. A screw is threaded to the inner side of the auxiliary block, and a nut is threaded to the outer side of the screw. Two protective components are fixedly connected to the top of the end cap bottom.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 and Figure 2This utility model provides an embodiment of a novel motor end cover that prevents copper wires from being thrown out. It includes an end cover bottom 1, a carbon crystal 2 fixedly connected to the top of the end cover bottom 1, the carbon crystal 2 being a core component of the internal conductive components of the motor, and its fixed connection ensuring the stability of current transmission. A connecting copper wire 3 is fixedly connected to the top of the carbon crystal 2, which is a critical path for current transmission and will tend to swing during operation with the motor. A reinforcing mechanism 6 is slidably connected to the outside of the end cover bottom 1. The reinforcing mechanism 6 is a core structure that enhances the connection stability between the end cover and the motor housing, and achieves flexible adaptation through the sliding connection.
[0026] The reinforcement mechanism 6 includes two arc-shaped shells 61. The two arc-shaped shells 61 can fit against the end cap bottom 1 and the outer side of the motor housing. The arc design increases the contact area to improve the fixing effect. The inner sides of the two arc-shaped shells 61 are slidably connected to the outer side of the end cap bottom 1. This sliding connection allows the arc-shaped shells 61 to be flexibly adjusted in position, providing adaptability for subsequent reinforcement. The two arc-shaped shells 61 are rotatably connected to a rotating shaft 65. The rotating shaft 65 serves as the fulcrum for the rotation of the arc-shaped shells 61, allowing the arc-shaped shells 61 to rotate around it to adjust the fitting angle. The rotating shaft 65 is slidably connected to the outer side of the end cap bottom 1, ensuring that the rotating shaft 65 can be adjusted in position with the rotation of the arc-shaped shells 61, ensuring stable contact between the arc-shaped shells 61 and the end cap bottom 1. The rotating shaft 65 is slidably connected to the outer side of the motor housing. Through the sliding connection with the motor housing, the connection stability between the reinforcement mechanism 6 and the motor housing is further enhanced.
[0027] Auxiliary blocks 62 are fixedly connected to the ends of the two arc-shaped shells 61 away from the rotating shaft 65. These blocks are key support components for locking the arc-shaped shells 61. Screws 63 are threadedly connected to the inner side of the auxiliary blocks 62. The screws 63 lock the two auxiliary blocks 62 through the threaded connection, so that the arc-shaped shells 61 fit tightly against the end cap bottom 1 and the motor housing. Nuts 64 are threadedly connected to the outer side of the screws 63. Nuts 64 cooperate with screws 63 to further tighten and prevent screws 63 from loosening, thereby improving the reliability of the reinforcement mechanism 6. A central hole 5 is opened inside the end cap bottom 1. The central hole 5 provides a passage for the motor rotating column to pass through, ensuring the installation space for the core rotating components of the motor.
[0028] Reference Figure 3 and Figure 4Two protective components 4 are fixedly connected to the top of the end cap bottom 1. The two protective components 4 are symmetrically arranged to form a double protective barrier to prevent the connecting copper bundle 3 from being thrown out. The protective component 4 includes a carbon crystal box 41, which wraps around the outside of the carbon crystal 2, providing installation positioning and protection for the carbon crystal 2 and ensuring the structural stability of the carbon crystal 2. The bottom of the carbon crystal box 41 is fixedly connected to the top of the end cap bottom 1. The fixed connection ensures that the position of the carbon crystal box 41 on the end cap bottom 1 is stable and avoids displacement due to vibration during operation. A shielding wall 42 is fixedly connected to the outside of the carbon crystal box 41. The shielding wall 42 acts as a physical barrier to intercept the thrown connecting copper bundle 3 and can directly prevent the connecting copper bundle 3 from deviating from its original trajectory.
[0029] The bottom of the shielding wall 42 is fixedly connected to the top of the end cap bottom 1. The fixed connection method ensures that the height of the shielding wall 42 is stable and ensures its interception effect when the connecting copper wire 3 swings. The inner side of the carbon crystal box 41 is slidably connected to the outer side of the carbon crystal 2, so that the carbon crystal 2 can be stably installed inside the carbon crystal box 41, ensuring that the connection structure between the carbon crystal 2 and the connecting copper wire 3 is stable.
[0030] Working principle: When the motor is running, the connecting copper wire 3 will swing with the motor. The increased shielding wall 42 is high enough to stop the connecting copper wire 3 during its swing. The surface of the shielding wall 42 is a flexible non-conductive material, so after contacting the connecting copper wire 3, it prevents the connecting copper wire 3 from swinging out and touching the housing, thus preventing poor insulation and withstand voltage. This ensures the safe operation of the motor and ensures that the motor always maintains a high-efficiency and stable working state, reducing maintenance costs and downtime losses. Furthermore, the shielding wall 42 is located on one side of the carbon crystal box 41, on the top of the end cover bottom 1, and does not affect other structures.
[0031] After the workers have installed the connection between the end cover bottom 1 and the motor housing, they first make contact with the rotating shaft 65 and the end cover bottom 1 and the motor housing. Then, they rotate the two arc-shaped shells 61 until they contact the end cover bottom 1 and the motor housing. Finally, they secure the connection between the end cover bottom 1 and the motor housing by fixing it with screws 63 and nuts 64. When it is necessary to repair the motor, the connection between the end cover bottom 1 and the motor housing is released by contacting the screws 63 and nuts 64. This structure ensures the smooth and efficient operation of the motor, while reducing downtime maintenance costs caused by connection failures and improving the reliability and safety of equipment operation.
[0032] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
