Description

Technical Field

[0001] This utility model belongs to the field of power systems, specifically relating to a force-saving output mechanism based on an eccentric counterweight wheel. Background Technology

[0002] Gas turbines, internal combustion engines, and other power engines have an economical operating speed. When electricity consumption fluctuates, causing changes in generator resistance, the power engine speed can easily drop below the economical operating speed range, further reducing combustion efficiency and leading to increased fuel consumption.

[0003] Currently, the industry urgently needs a power system that can mitigate engine speed fluctuations. Furthermore, existing power transmission methods have limitations in increasing torque output, making it difficult to meet the power generation industry's demand for high-efficiency power output. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model provides a force-saving output mechanism based on an eccentric counterweight wheel, which can act as an energy storage mechanism and continuously output power by means of its own inertia after power input, so as to achieve the effect of force-saving output in conjunction with power equipment.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A force-saving output mechanism based on an eccentric counterweight wheel includes a support frame. A first power mechanism is mounted on the support frame. The first power mechanism includes a first counterweight wheel, a first transmission wheel, a first outer support wheel, and a first inner support wheel. The first counterweight wheel has a ring-shaped structure, and its outer ring has teeth. The first transmission wheel and the first outer support wheel are both gears and mesh with the teeth of the outer ring of the first counterweight wheel for transmission. The first inner support wheel abuts against the inner ring of the first counterweight wheel. The contact points of the first transmission wheel, the first outer support wheel, the first inner support wheel, and the first counterweight wheel with the first counterweight wheel are located on the same side of the vertical plane of the center of gravity of the first counterweight wheel.

[0007] The first inner support wheel is a roller with a smooth outer wall, and the inner wall of the first counterweight wheel is a smooth annular surface.

[0008] The bracket is also provided with a second power mechanism, which includes a second counterweight wheel and a second transmission wheel. The outer ring of the second counterweight wheel is provided with teeth and meshes with the first transmission wheel and the second transmission wheel for transmission. The first transmission wheel and the second transmission wheel respectively mesh with the two sides of the second counterweight wheel. The height of the line connecting the meshing points of the first transmission wheel and the second transmission wheel is lower than the horizontal plane where the center of gravity of the second counterweight wheel is located.

[0009] The second power mechanism also includes a second inner support wheel, which presses against the lower side of the inner ring of the second counterweight wheel.

[0010] The second power mechanism is configured in multiple stages in series on the support, with the second counterweight wheel of the next stage meshing with the second transmission wheel of the previous stage for transmission.

[0011] The bracket is also provided with anti-sway rollers on both sides. The anti-sway rollers are symmetrically arranged on both sides of the first counterweight wheel and abut against the side of the first counterweight wheel to form a limiting fit.

[0012] The weight of the first and second counterweight wheels is greater than 1 ton.

[0013] The beneficial effects of this utility model are:

[0014] By engaging the first counterweight wheel with a power engine such as a gas turbine, the counterweight wheel gains initial kinetic energy and maintains inertia due to its own weight. When the resistance at the generator load end changes, it is not easy to affect the speed of the power engine, thus avoiding frequent departures from the economic speed range, improving fuel utilization efficiency and reducing losses.

[0015] The contact points of the first drive wheel, the first outer support wheel, the first inner support wheel, and the first counterweight wheel are on the same side of their center of gravity vertical plane, causing the support point to be offset from the center of gravity, facilitating subsequent connection to the power unit. The first drive wheel and the second drive wheel mesh with the two sides of the second counterweight wheel respectively, and the line connecting the meshing points is lower than the horizontal plane where their centers of gravity are located, achieving effective support for the second counterweight wheel. The output mechanism can be connected in series, with each unit having energy storage; series connection can increase and amplify the torque, providing power for power generation. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model;

[0017] In the attached diagram, 1 is the support frame, 2 is the first counterweight wheel, 3 is the first transmission wheel, 4 is the first outer support wheel, 5 is the first inner support wheel, 6 is the second counterweight wheel, 7 is the second transmission wheel, 8 is the second inner support wheel, and 9 is the anti-sway roller. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] Specific implementation examples Figure 1As shown, this utility model is a labor-saving output mechanism based on an eccentric counterweight wheel, including a bracket 1. A first power mechanism is mounted on the bracket 1. The first power mechanism includes a first counterweight wheel 2, a first transmission wheel 3, a first outer support wheel 4, and a first inner support wheel 5. The first counterweight wheel 2 has a ring-shaped structure, and its outer ring has teeth. The first transmission wheel 3 and the first outer support wheel 4 are gears that mesh with the teeth of the outer ring of the first counterweight wheel 2 for transmission. The first inner support wheel 5 abuts against the inner ring of the first counterweight wheel 2. The contact points of the first transmission wheel 3, the first outer support wheel 4, the first inner support wheel 5, and the first counterweight wheel 2 are located on the same side of the vertical plane of the center of gravity of the first counterweight wheel 2. Figure 1 As shown, the first inner support wheel 5 is a roller with a smooth outer wall, and the inner wall of the first counterweight wheel 2 is a smooth annular surface. The first inner support wheel 5 abuts against the inner ring of the first counterweight wheel to prevent displacement of the first counterweight wheel.

[0020] This utility model is a power system specifically designed for the power generation industry. It uses a gas turbine, internal combustion engine, or other power engine to mesh and drive the first counterweight wheel, enabling the first counterweight wheel to gain initial kinetic energy and maintain a large inertia under its own weight. The power is then transmitted to the outside through the first transmission wheel 3. If multiple stages are connected in series and the output is carried out by the transmission wheel at the end of the series, changes in the load end of the generator will not easily affect the speed of the gas turbine, internal combustion engine, or other power engines. This avoids the power engine frequently falling out of the economic speed range, improves fuel utilization efficiency, and reduces losses.

[0021] The first counterweight wheel 2 and the second counterweight wheel 6 have a weight greater than 1T. When the power machine cuts off the meshing input, due to the large weight of the first and second counterweight wheels, the stored kinetic energy can be transmitted outward for a relatively long time under the action of the wheel body's own inertia, achieving a continuous kinetic energy output effect. This can provide backup energy for the occasional shutdown of the power machine and avoid power generation interruption accidents.

[0022] The contact points of the first transmission wheel 3, the first outer support wheel 4, the first inner support wheel 5 and the first counterweight wheel 2 are located on the same side of the vertical plane of the center of gravity of the first counterweight wheel 2, so that the support points of the first transmission wheel 3, the first outer support wheel 4 and the first inner support wheel 5 are offset from the center of gravity of the first counterweight wheel 2, leaving space for later connection of the power unit.

[0023] like Figure 1 The center of the first transmission wheel 3 is slightly lower than the plane where the center of gravity of the first counterweight wheel 2 is located. The line connecting the center of gravity of the first counterweight wheel 2 and the center of the first transmission wheel 3 makes an angle of 1-2° with the horizontal plane to ensure that the counterweight wheel can provide support with the help of the transmission wheel. Figure 1As shown, angle A is the angle between the lines connecting the first counterweight wheel 2, the first outer support wheel 4, and the first inner support wheel 5, which is 13-16°. Angle B is the angle between the lines connecting the first counterweight wheel 2, the first transmission wheel 3, and the first inner support wheel 5, which is 18-20°. By setting the range of angles A and B, the first transmission wheel 3, the first outer support wheel 4, and the first inner support wheel 5 are positioned on the same side of the vertical plane of the center of gravity of the first counterweight wheel 2 to ensure eccentric setting.

[0024] Furthermore, the support 1 is also equipped with a second power mechanism, which includes a second counterweight wheel 6 and a second transmission wheel 7. The outer ring of the second counterweight wheel 6 is toothed and meshes with the first transmission wheel 3 and the second transmission wheel 7 for transmission. The first transmission wheel 3 and the second transmission wheel 7 respectively mesh on both sides of the second counterweight wheel 6. The height of the line connecting the meshing points of the first transmission wheel 3 and the second transmission wheel 7 is lower than the horizontal plane where the center of gravity of the second counterweight wheel 6 is located. With the support of the first transmission wheel 3 and the second transmission wheel 7, the second counterweight wheel can be supported.

[0025] The output mechanisms of this application can be used in series. Each unit has its own energy storage. Using them in series can effectively increase and enhance the torque, providing the power required for power generation.

[0026] Furthermore, the second power mechanism also includes a second inner support wheel 8, which presses against the lower side of the inner ring of the second counterweight wheel 6. The compression of the second inner support wheel 8 ensures stable operation of the second counterweight wheel 6, preventing it from bouncing.

[0027] Furthermore, the second power mechanism is configured with multiple stages in series on the support 1, with the second counterweight wheel 6 of the next stage meshing with the second transmission wheel 7 of the previous stage. The diameter of the counterweight wheel of the next stage is larger than that of the counterweight wheel of the previous stage, so that the number of teeth of the gear ring increases step by step, and the rotation speed of each single machine is different. This avoids resonance damage while increasing torque and can resist greater load changes.

[0028] Furthermore, anti-sway rollers 9 are also provided on both sides of the bracket 1. The anti-sway rollers 9 are symmetrically arranged on both sides of the first counterweight wheel 2 and abut against the side of the first counterweight wheel 2 to form a limiting fit. The anti-sway rollers 9 can be arranged in pairs on both sides of the first counterweight wheel 2 and the second counterweight wheel to prevent swaying and reduce vibration.

[0029] Furthermore, the bracket 1 is also covered with a sealing cover to prevent the intrusion of external debris and ensure safe operation.
