Mechanical transmission annular permanent magnets are ring-shaped magnetic functional components designed for mechanical power transmission, magnetic coupling transmission, bearing positioning and mechanical buffer transmission systems, widely used in industrial transmission equipment, mechanical automation devices, pump valve machinery, precision bearings and other mechanical fields. Produced from high-performance neodymium iron boron and ferrite permanent magnet materials through integral molding and precision finish turning, the annular magnets feature concentricity accuracy, uniform circumferential magnetic field, stable magnetic torque and strong transmission stability, which can realize non-contact magnetic transmission, magnetic force limit and power auxiliary transmission for mechanical equipment.

Different from solid magnets, the hollow annular structure of mechanical transmission magnets perfectly matches the assembly requirements of rotating shafts, bearings and shaft core parts of mechanical equipment, realizing nested assembly and coaxial operation. The product adopts circumferential uniform magnetization or multi-pole alternating magnetization technology, which can generate stable and uniform rotating magnetic field during the operation of mechanical equipment, convert magnetic energy into mechanical transmission power, and realize non-contact power transmission. This non-contact transmission mode effectively avoids mechanical friction and wear between traditional transmission parts, reduces equipment operation noise and failure rate, and greatly prolongs the service life of mechanical transmission systems.

In terms of performance, the annular permanent magnet has high magnetic energy product and strong magnetic torque, which can meet the power transmission requirements of low-speed high-torque and high-speed stable operation of mechanical equipment. The product has excellent mechanical stability, not easy to demagnetize and deform during high-speed rotation and frequent starting and stopping, and maintains continuous and stable transmission performance. After surface anti-corrosion and wear-resistant treatment, it can adapt to harsh working environments such as mechanical vibration, oil immersion and high-temperature operation. It is widely used in magnetic couplings, magnetic transmission pumps, precision instrument rotating parts, automation equipment transmission shafts and other equipment, playing the roles of power transmission, torque buffering, vibration reduction and positioning limit. While improving the transmission efficiency of mechanical equipment, it reduces equipment maintenance costs and energy consumption, and is an important core component of modern high-efficiency and low-wear mechanical transmission systems.
