Permanent magnet transmission device with water-cooled heat dissipation device

Abstract

The invention relates to a permanent magnet transmission device with a water-cooled heat dissipation device. The permanent magnet transmission device comprises an active copper rotor component arranged on a driving shaft 4, permanent magnet rotor components arranged on driven shafts 15 and 16, and a screw rod regulator, wherein the active copper rotor component is formed by a disc-shaped steel frame 7 and a copper conducting ring 8, the surface of the steel plate is provided with the copper conducting ring; the opposite surfaces of the permanent magnet rotor components and the active copper rotor component are embedded with permanent magnets 10; the opposite surfaces of the active copper rotor component and the permanent magnet rotor components are spaced by an adjustable axial air gap 9,and the active copper rotor component and the permanent magnet rotor components are coupled through the magnetic force. When permanent magnet transmission device is loaded, the medium-high speed operation is required, and the advantage of replacing a frequency converter under the working condition that the power is more than 50KW is obvious; adaptability and maintenance-free performance in severeworking environments are high; the interference of the motor can be eliminated, and the working efficiency of the motor is improved; the vibration transmission between the motor and the load can be eliminated; the maintenance and repair cost is low; and the service life of each main part of the transmission system can be effectively prolonged.

Description

technical field [0001] The invention relates to the field of permanent magnet transmission, in particular to a permanent magnet transmission with a water-cooled heat sink. Background technique [0002] The permanent magnet transmission technology is not simply using the principle of magnets of the same sex repelling each other and opposite sexes attracting each other, it is the integration of transmission technology, material technology and manufacturing technology. Manufacturing technology in the 21st century will not only continue to manufacture machines and equipment operating under normal conditions, but also manufacture machinery and equipment operating in extreme environments. The products manufactured in the 21st century should be green products that are energy-saving, environmentally friendly, and friendly to people. Magnetic drive technology is just to adapt to this development trend came into being. With the continuous emergence of new technologies, new processes,...

Problems solved by technology

[0003] Domestic motors and driven equipment generally have unreasonable system matching, the phenomenon of "big horse-drawn carts" is serious, and the equipment operates at low load for a long time; the system adjustment method is backward, most fans and pumps are adjusted by mechanical throttling, and the efficiency ratio is adjusted. speed way lower than 30%

[0004] At present, the commonly used transmission device has the adaptability and maintenance-free performance in harsh working environments, and the transmission of harmonic interference has low performance. The resonance effect is obviously not conducive to kinetic energy transmission and energy saving and environmental protection.
