Abstract
The utility model belongs to the field of mechanical transmission, particularly a permanent magnet isolation transmission device which comprises a motor and a working machine, wherein the shaft end of the motor is provided with a drive disk, and permanent magnets are evenly distributed on the working face of the drive disk; the shaft end of the working machine is provided with a driven disk, and permanent magnets are evenly distributed on the working face of the driven disk; an isolation cover which is made of insulating material without magnetoconductivity is arranged between the drive disk and the driven disk; magnetic lines pass through the isolation cover to make the same poles of the drive disk and the driven disk mutually attractive and the reverse poles of the drive disk and the driven disk mutually repellent. When the utility model work, the drive disk drives the driven disk to rotate. The utility model has small dimension, and safe and reliable dynamic force for transmission, and can not cause mechanical accidents caused by overload.
Description
The utility model belongs to mechanical transmission fields, and particularly permanent magnet is isolated transmission device.
All adopt coupling or drive wheel to realize to work mechanism transmission of power at the mechanical transmission fields motor by the driving belt transmission.Under different working environments, the coupling of transmission different capacity and belt transmission, chain-driven is standardization, standardization all, and its reliable transmission is easy to use.Its deficiency is that maintenance, maintenance work amount are big, particularly for low power water pump, washing machine, refrigerator-freezer, refrigerator, adopts belt transmission boundary dimension big, adopts the coupling transmission when work mechanism overloads, and mechanical accident takes place easily.
The purpose of this utility model is to provide a kind of permanent magnet to isolate transmission device, and not only transfer motion power is reliable, and is easy to use, safeguard, the maintenance work amount is little, and boundary dimension is little, when work mechanism overloads, motor and work mechanism can break away from voluntarily, prevent the generation of mechanical accident.
The utility model is achieved in that a kind of permanent magnet isolation transmission device, comprise motor and work mechanism, axle head at motor is installed with the active disk that working surface is evenly equipped with permanent magnet, axle head at work mechanism is installed with the driven disk that working surface is evenly equipped with permanent magnet, and the shielding can of using non-magnetic conduction insulating material to constitute is being set between the working surface of the working surface of active disk and driven disk.
Because of shielding can is made of non-magnetic conduction insulating material, can make the magnetic line of force pass shielding can, the magnetic pole same sex of the magnetic pole of disk initiatively and driven disk is repelled each other, there is a natural attraction between the sexes, thereby when making the utility model work, initiatively disk drive driven disk and rotate.Because of shielding can is so that insulating material constitutes when the active disk rotates, can not produce induction current, just do not have energy loss yet, its boundary dimension is littler than bel-drivenn physical dimension, isolates transmission because the transmission between active disk and the driven disk is a permanent magnet, when work mechanism overloads, motor and work mechanism do not break away from voluntarily, and mechanical accident can take place, safe and reliable, easy to use, safeguard, the maintenance work amount is little.
