Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator technology, and in particular to a generator housing with shock absorption function. Background Technology
[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, which converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and then transmits it to the generator, which in turn converts it into electrical energy. Generators have a wide range of uses in industrial and agricultural production, national defense, science and technology and daily life.
[0003] Generators inevitably vibrate during operation. Vibration not only affects the generator's stability and lifespan but can also cause additional noise pollution, interfering with the surrounding environment and equipment. Currently, common generator casings are inadequate in terms of vibration damping. Some casings simply use rubber pads or other single vibration damping methods, which have limited damping effect and are difficult to cope with the different frequencies and amplitudes of vibration generated by the generator under complex operating conditions. If the generator's vibration is not effectively suppressed, internal components will be in an unstable state for a long time, accelerating wear and leading to frequent generator failures and increased maintenance costs. Utility Model Content
[0004] The problem this invention aims to solve is to provide a generator housing with shock absorption function that can effectively cope with vibrations under complex working conditions, significantly extend the service life of the generator, and greatly reduce maintenance costs.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a generator housing with shock absorption function, including a housing, a rubber pad fixedly connected to the inner wall of the housing, an elastic element fixedly connected to the inner bottom wall of the housing, a shock absorption assembly provided inside the housing, a bearing plate fixedly connected to the end of the elastic element away from the inner bottom wall of the housing, a ball bearing rotatably connected to the inner wall of the bearing plate, and the outer surface of the ball bearing rolling contact with the inner wall of the rubber pad, and a fixing assembly provided above the bearing plate.
[0006] Preferably, in the above-mentioned generator housing with shock absorption function, the shock absorption component includes a movable column fixedly connected to the bottom surface of the bearing plate, the inner wall of the movable column is rotatably connected to a limiting shaft, and the outer surface of the limiting shaft is fixedly connected to a rocker.
[0007] Preferably, in the above-mentioned generator housing with shock absorption function, the inner wall of the rocker is rotatably connected to a limiting shaft two, the outer surface of the limiting shaft two is fixedly connected to a limiting frame, and the bottom surface of the limiting frame is fixedly connected to the inner bottom wall of the housing.
[0008] Preferably, in the above-mentioned generator housing with shock absorption function, an elastic element two is fixedly connected to the outer surface of the seesaw, and the end of the elastic element two away from the seesaw is fixedly connected to the bottom surface of the bearing plate.
[0009] Preferably, in the above-mentioned generator housing with shock absorption function, the fixing component includes a vertical plate fixedly connected to the upper surface of the support plate, an adjusting screw is threadedly connected to the inner wall of the vertical plate, a knob is fixedly connected to one end of the adjusting screw, and a limit disc is fixedly connected to the other end of the adjusting screw.
[0010] Preferably, in the above-mentioned generator housing with shock absorption function, the outer surface of the limiting disc is rotatably connected to a clamping plate, and the bottom surface of the clamping plate is slidably connected to the upper surface of the bearing plate, and a protective pad is fixedly connected to the outer surface of the clamping plate.
[0011] The advantages and beneficial effects of this utility model are:
[0012] I. This utility model, by setting an elastic element, can initially buffer the vibration generated by the generator operation, effectively reducing the overall vibration amplitude. By setting a damping component, the vibration energy is further absorbed and dispersed by utilizing the lever principle and the deformation of the elastic element. By setting ball bearings and rubber pads, the sliding friction of the bearing plate can be converted into rolling friction, greatly reducing vibration transmission. Through the coordinated use of the elastic element, damping component, ball bearings, and rubber pads, compared with the traditional single damping method, it can more efficiently cope with vibrations of different frequencies and amplitudes under complex working conditions, significantly improving the generator's vibration damping effect, effectively protecting the generator's internal components, extending their service life, and reducing maintenance costs.
[0013] II. By rotating the adjusting screw, the limiting disc fixedly connected to one end of the adjusting screw will rotate accordingly. The clamping plate rotatably connected to the outer surface of the limiting disc will move horizontally toward the generator placed on the support plate under the drive of the rotating limiting disc, thereby clamping the generator. The protective pad fixedly connected to the outer surface of the clamping plate can tightly abut against the outer surface of the generator, thereby achieving the purpose of effectively protecting the generator surface from scratches while fastening the generator.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0021] like Figures 1 to 5 As shown, a generator housing with shock absorption function includes a housing 1. The housing 1 serves as an integral support frame and is made of high-strength aluminum alloy. This material is not only lightweight, which helps reduce the weight of the entire generator and facilitates handling and installation, but also has good corrosion resistance and mechanical strength, which can effectively resist the erosion of the external environment and the impact force that may be generated during the operation of the generator, ensuring the safety and stability of the internal components.
[0022] The rubber pad 2, which is fixedly connected to the inner wall of the housing 1, is made of high-elasticity nitrile rubber. Nitrile rubber has excellent oil resistance, wear resistance and anti-aging properties, and can maintain good elasticity for a long time. The rubber pad 2 is ring-shaped and tightly fits the inner wall of the housing 1. Its function is to provide an elastic support surface for the bearing plate 5 and to effectively buffer the collision between the bearing plate 5 and the inner wall of the housing 1 during vibration, reduce friction and noise generation, and further absorb vibration energy.
[0023] The elastic element 3, which is fixedly connected to the inner bottom wall of the housing 1, is a helical spring made of high-quality spring steel. The helical spring has good elastic deformation capacity and high elastic coefficient. Its helical shape can evenly distribute stress when subjected to pressure, ensuring that it can stably play a buffering role under vibration in different directions. The main function of the elastic element 3 is to initially buffer the vibration generated by the generator operation, greatly reduce the overall vibration amplitude, and create favorable conditions for subsequent vibration reduction.
[0024] The housing 1 is equipped with a shock absorption component 4, which plays a key role in energy absorption and dispersion in the entire shock absorption system. The movable column 401 in the shock absorption component 4 is made of stainless steel. Stainless steel has good corrosion resistance and high strength, which can ensure stable operation in long-term vibration environment. The movable column 401 is cylindrical, and its upper surface is fixedly connected to the bottom surface of the bearing plate 5. This structural design allows the displacement of the bearing plate 5 to be accurately transmitted to the movable column 401.
[0025] The limiting shaft 402, which is rotatably connected to the inner wall of the moving column 401, is made of high-strength alloy steel. The high strength of the alloy steel ensures that the limiting shaft 402 is not easily deformed during frequent rotation. The limiting shaft 402 is a solid shaft, and the rocker plate 403, which is fixedly connected to its outer surface, is made of aluminum alloy. Aluminum alloy is lightweight and has high strength, which can effectively reduce the weight of the entire shock absorption assembly 4. The rocker plate 403 is shaped like a lever. This shape design utilizes the lever principle. When the moving column 401 drives the limiting shaft 402 to rotate, the rocker plate 403 can rotate around the limiting shaft 404, thereby converting and dispersing the vibration energy.
[0026] The second limiting shaft 404, which is rotatably connected to the inner wall of the rocker 403, is also made of high-strength alloy steel. The limiting frame 405, which is fixedly connected to the outer surface of the second limiting shaft 404, is made of carbon steel. Carbon steel has a certain strength and good processing performance. The bottom surface of the limiting frame 405 is fixedly connected to the inner bottom wall of the housing 1. Its function is to provide a stable support point for the rocker 403, limit the rotation range of the rocker 403, and ensure the stability and reliability of the shock absorption assembly 4 during operation.
[0027] The elastic element 406, which is fixedly connected to the outer surface of the seesaw 403, is an elastomer made of silicone rubber. Silicone rubber has excellent high temperature resistance, low temperature resistance and good elastic recovery ability. One end of it is fixedly connected to the outer surface of the seesaw 403, and the other end is fixedly connected to the bottom surface of the bearing plate 5. During the rotation of the seesaw 403, the elastic element 406 will undergo tensile or compressive deformation, and its elastic force will be used to further absorb and disperse vibration energy, effectively weakening the vibration intensity.
[0028] The bearing plate 5, which is fixedly connected to the end of the elastic element 3 away from the inner bottom wall of the housing 1, is made of high-strength engineering plastic. This material has the advantages of light weight, high strength and good insulation performance. The bearing plate 5 is in the shape of a circular flat plate. Its large surface area can provide a stable installation platform for the generator and facilitates connection with other components.
[0029] The ball bearings 6 rotatably connected to the inner wall of the bearing plate 5 are composed of stainless steel balls and matching ball bearings. The stainless steel balls have good wear resistance and rolling performance, which can reduce the friction between the ball bearings 6 and the inner wall of the bearing plate 5. The ball bearings 6 roll between the bearing plate 5 and the rubber pad 2, transforming the original sliding friction between the bearing plate 5 and the rubber pad 2 into rolling friction, which greatly reduces the coefficient of friction, reduces vibration transmission, makes the movement of the bearing plate 5 smoother during vibration, and further improves the shock absorption effect.
[0030] A fixing component 7 is provided above the support plate 5. This component is used to stabilize the generator and ensure that it remains stable during operation.
[0031] The upright plate 701 in the fixing component 7 is made of carbon steel. The strength of carbon steel can meet the force that the upright plate 701 will bear during the fixing of the generator. The upright plate 701 is in the shape of a straight plate and is vertically fixed to the upper surface of the bearing plate 5, providing a support base for subsequent adjustment and clamping structures.
[0032] The adjusting screw 702, which is threaded to the inner wall of the vertical plate 701, is made of high-strength alloy steel. The high strength of the alloy steel ensures that the adjusting screw 702 is not easily damaged during frequent adjustments.
[0033] The knob 703, which is fixedly connected to one end of the adjusting screw 702, is made of engineering plastic. Engineering plastic has good insulation and a good grip, making it convenient for operators to turn the adjusting screw 702.
[0034] The other end of the adjusting screw 702 is fixedly connected to the limiting disc 704, which is made of stainless steel. The corrosion resistance and hardness of stainless steel can ensure that the limiting disc 704 works stably for a long time.
[0035] The clamping plate 705, which is rotatably connected to the outer surface of the limiting disc 704, is made of aluminum alloy. Aluminum alloy is lightweight and has moderate strength. The clamping plate 705 is arc-shaped, and its bottom surface is slidably connected to the upper surface of the support plate 5. By rotating the adjusting screw 702, the limiting disc 704 drives the clamping plate 705 to move horizontally toward the generator placed on the support plate 5, thereby clamping the generator.
[0036] The protective pad 706, which is fixedly connected to the outer surface of the clamping plate 705, is made of rubber. Rubber has good elasticity and cushioning properties. The protective pad 706 can fit tightly against the outer surface of the generator, which can not only prevent scratch damage to the generator surface during clamping, but also change the clamping tightness of the clamping plate 705 on the generator according to the actual vibration of the generator by fine-tuning the adjusting screw 702, thereby enhancing the stability of the generator and avoiding excessive clamping that would cause additional pressure on the generator.
[0037] Working principle: When the generator is put into operation and generates vibration, the entire vibration damping system immediately takes effect. The elastic element 3 installed on the bottom wall inside the housing 1 responds first. With its own elastic properties, it acts like a buffer pad to initially dissipate the impact force generated by the generator vibration, thereby effectively reducing the overall vibration amplitude of the generator and laying the foundation for subsequent vibration damping. As the vibration continues, the bearing plate 5 is displaced under the action of vibration. The movable column 401 fixedly connected to the bottom surface of the bearing plate 5 will move synchronously with the displacement of the bearing plate 5. The movement of the movable column 401 drives the limit shaft 402, which is rotatably connected to its inner wall, to rotate. The rocker arm fixedly connected to the outer surface of the limit shaft 402... Plate 403 will also begin to rotate around the limiting shaft 404. During the rotation of the rocker plate 403, the elastic element 406 connected between the outer surface of the rocker plate 403 and the bottom surface of the bearing plate 5 will undergo corresponding tensile or compressive deformation. During the deformation process, the elastic element 406 uses its own elastic force to further absorb and disperse the energy carried by the vibration, just like a sponge absorbing water, gradually consuming the energy of the vibration and further weakening the intensity of the vibration. At the same time, the ball bearing 6 plays a key role between the bearing plate 5 and the rubber pad 2. Due to the presence of the ball bearing 6, the sliding friction between the bearing plate 5 and the rubber pad 2 is converted into rolling friction. Compared with sliding friction, rolling friction is more efficient. The friction generates less resistance, which greatly reduces the transmission of vibration on this contact surface, effectively blocking the vibration propagation path and further reducing the impact of vibration on the generator casing and the surrounding environment. In addition, the fixing component 7 also plays an indispensable role in the entire vibration reduction process. By rotating the adjusting screw 702, the limiting disc 704, which is fixedly connected to one end of the adjusting screw 702, will rotate accordingly. The clamping plate 705, which is rotatably connected to the outer surface of the limiting disc 704, will move horizontally toward the generator placed on the support plate 5 under the drive of the rotation of the limiting disc 704, thereby clamping the generator. The protective pad 7 is fixedly connected to the outer surface of the clamping plate 705. The clamping plate 705 can tightly abut against the outer surface of the generator, which not only prevents scratches and damage to the generator surface during clamping, but also allows for adjustments to the clamping tightness of the clamping plate 705 based on the actual vibration of the generator. When the generator vibration is severe, the clamping force can be increased appropriately to enhance the generator's stability; when the vibration is mild, the clamping force can be reduced appropriately to avoid excessive clamping and additional pressure on the generator. In this way, the entire system, through the coordinated work of multiple components, suppresses and buffers the generator vibration from multiple dimensions, achieving a highly efficient vibration reduction effect and ensuring that the generator can continue to operate in a stable state.
