Publish Time: 2024-11-13
As a new type of transmission device, the design and functional innovation of the permanent magnetic coupling are mainly reflected in the following aspects:1. Design innovationStructural innovation:The permanent magnetic coupling adopts a non-contact magnetic transmission method, avoiding the friction and wear caused by mechanical contact of the traditional mechanical coupling, thereby reducing energy loss. This design not only improves the transmission efficiency, but also effectively extends the service life of the equipment.In terms of structure, the permanent magnetic coupling usually includes components such as the active rotor, the driven rotor and the permanent magnet. By optimizing the design of these components, such as using high-performance permanent magnetic materials and reasonable magnetic circuit design, the transmission performance and efficiency can be further improved.Material innovation:The application of high-performance permanent magnetic materials (such as neodymium iron boron) makes the permanent magnetic coupling have a higher magnetic energy product and better magnetic stability, thereby improving the transmission efficiency and reliability.At the same time, the use of lightweight and high-strength materials (such as aluminum alloy, stainless steel, etc.) to make the housing and bracket of the coupling can further reduce the weight and improve the overall performance of the equipment.Integrated design:Modern permanent magnetic couplings often integrate multiple functions, such as overload protection, speed regulation, soft start, etc. The integration of these functions not only improves the practicality of the equipment, but also makes the equipment more intelligent and easy to control.2. Functional innovationEfficient transmission:Permanent magnetic couplings transmit torque through magnetic force and can achieve transmission without mechanical contact. This non-contact transmission method makes energy conversion more efficient and effectively reduces energy consumption.At the same time, due to the avoidance of mechanical friction and wear, the transmission efficiency of permanent magnetic couplings is much higher than that of traditional mechanical couplings.Overload protection:Permanent magnetic couplings have overload protection function. When the load exceeds the set value, the torque transmitted by the magnetic force will decrease, thereby protecting the motor and transmission system from damage. This function is particularly important in situations where frequent starting and stopping are required.Speed regulation function:Some permanent magnetic couplings also have speed regulation function. By changing the gap between the active rotor and the driven rotor or the strength of the magnetic field, the output speed and output torque can be easily adjusted. This speed regulation method is not only simple and reliable, but also has a wide speed regulation range.Soft start:The soft start function of the permanent magnet coupling can reduce the starting current impact and protect the motor and power supply system. At the same time, soft start can also reduce the vibration and noise of the equipment and improve the operating stability of the equipment.Environmental protection and energy saving:As a green transmission device, the permanent magnet coupling has significant environmental protection and energy saving effects. The torque is transmitted by magnetic force, which avoids the friction and wear caused by mechanical contact of traditional mechanical couplings, thereby reducing energy loss and pollutant emissions.Permanent magnet couplings have shown many innovations in design and functionality. These innovations not only improve the transmission efficiency and reliability of the equipment, but also make the equipment more intelligent, environmentally friendly and energy-saving. With the continuous advancement of technology and further reduction of costs, permanent magnet couplings are expected to be widely used in more fields, providing better solutions for the trend of modern industrial automation and energy conservation and emission reduction.
