[0002] With the rapid development of my country's chemical and manufacturing industries, the requirements for gap adjustment accuracy in machines, equipment and process flows are getting higher and higher. Gap adjustment is not only related to production efficiency, but also directly related to product quality and stable operation of equipment. Traditional manual adjustment or limit measures can no longer meet the high requirements of modern manufacturing for accuracy and efficiency in many cases.

[0003] Especially in harsh environments and strict process requirements, such as high temperature, high pressure, high humidity or strong corrosive environments, manual adjustment is not only inefficient, but may also cause equipment damage or substandard product quality due to operational errors. In addition, repeated operations also increase the labor intensity and safety risks of operators. Therefore, a power adjustment device is proposed. Utility Model Content

[0006] The utility model is further configured as follows: the radial clearance between the movable block and the shaft is 1 to 2 mm.

[0007] The utility model is further configured as follows: the number of the centrifugal blocks is four.

[0008] The utility model is further configured as follows: a radial clearance between each of the stationary centrifugal blocks and the shaft is matched to be 0.25 times the shaft diameter.

[0009] The beneficial technical effect of the utility model is as follows: the working principle of the application is based on the interaction between centrifugal force and spring elastic force.

[0016] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0017] The utility model proposes a power, including a shaft 1, wherein the outer wall circumference of the shaft 1 is sequentially installed with a moving block 2, a centrifugal block 3 and a fixed sleeve 4 from left to right, wherein the centrifugal blocks 3 are four. The fixed sleeve 4 is fixedly installed on the shaft 1 and rotates with the shaft. The right side of the moving block 2 is a conical surface and matches the left end face of the centrifugal block 3, and the right side of the centrifugal block 3 is also a conical surface and matches the left end face of the fixed sleeve 4. The moving block 2, the centrifugal block 3 and the fixed sleeve 4 are all provided with matching through holes and are penetrated with studs 5, and the left end of the stud 5 penetrates the outside of the moving block 2 and is installed with an adjustment nut 6, and the moving block 2 is provided with a groove matching the size of the adjustment nut 6, and a spring 7 is installed in the groove, and the spring 7 is sleeved on the stud 5 and is located on the right side of the adjustment nut 6. The radial clearance between the moving block 2 and the shaft 1 is 1 to 2 mm. The radial clearance between each of the stationary centrifugal blocks 3 and the shaft is 0.25 times the shaft diameter.

[0018] During operation, the centrifugal block 3 moves radially away from the shaft 1 under the action of centrifugal force. The conical surface of the centrifugal block 3 applies pressure to the conical surface of the movable block 2 and the fixed sleeve 4. The fixed sleeve 4 is fixed on the shaft 1, so the centrifugal block 3 axially pushes the movable block 2 to compress the spring 7. When the centrifugal force is greater than the spring elastic force, the movable block 2 moves away from the centrifugal block 3 to achieve the purpose of power adjustment. When stationary, the centrifugal force of the centrifugal block 3 gradually decreases to zero with the shaft speed, the spring 7 stretches and pushes the movable block 2 to move toward the centrifugal block 3, and the centrifugal block 3 moves radially toward the direction of the shaft, and finally returns to the initial state.

[0019] The working principle of this application is based on the interaction between centrifugal force and spring elastic force. When the device starts to rotate, the centrifugal block will generate an outward force due to the centrifugal force. This force overcomes the elastic force of the spring, thereby pushing the moving block to move and achieving the purpose of adjustment. Since this device is an integral part of the entire equipment, it is not limited by engineering conditions.

[0020] In some high-precision mechanical equipment, this device can be used to accurately control the position and angle of parts, thereby ensuring the quality and performance of the product. In addition, this device can also achieve more functions and applications through some innovative designs. For example, the size and direction of the centrifugal force generated can be adjusted by changing the mass and shape of the centrifugal block, thereby achieving more precise control of the moving block. At the same time, it is also possible to adapt to different engineering conditions and requirements by changing the stiffness and preload of the spring. The present application has the characteristics of simple structure, easy operation, and high reliability, which makes it have broad application prospects in various engineering fields.
