Summary of the invention
The objective of the invention is to overcome above-mentioned defective, provide that a kind of transmission is contactless, the operation noiselessness, do not have friction, high-power permanent magnet speed increasing box that power loss is little.
Technical solution of the present invention is: a kind of high-power permanent magnet speed increasing box, and it comprises housing, be erected at power shaft and output shaft on the housing, be installed in the drive in the housing; Be provided with supporting bracket in the housing, the dead in line of power shaft and output shaft, power shaft is located at by bearing bracket stand on the protecgulum and supporting bracket of housing, and output shaft is located on the bonnet and supporting bracket of housing by bearing bracket stand; The even jack shaft that distributes more than two around power shaft and the output shaft, jack shaft is parallel with output shaft with power shaft, and jack shaft is located between the protecgulum and bonnet of housing by bearing bracket stand; Be installed with the input drive on the power shaft, be installed with output drive wheel on the output shaft, be installed with respectively in the middle of the input with input drive and output drive wheel transmission drive in the middle of the drive and output on each jack shaft; It is characterized in that: described drive is a permanent magnetic wheels, and it comprises carriage, the embedded permanent magnetism tile that is installed in bracket surface that compresses, and the permanent magnetism tile is the number of pole-pairs setting, leaves air gap between two permanent magnetic wheels of transmission mutually.
Described air gap is more than or equal to 1 millimeter.
The speed increasing ratio of described gearbox was at 1: 4～1: 50, and the permanent magnetism tile number of pole-pairs beguine of permanent magnetism drive distributes according to speed increasing ratio.
The size of described permanent magnetism tile is according to the torque arithmetic of power shaft and output shaft.
Described bearing is the zanjon bearing.
The present invention has simple in structure, and transfer torque is big; Be convenient to realize integrated process and assemble, one-time positioning is finished during assembling, the assembly precision height; The concentricity height is convenient to on-the-spot the installation; Maintenance is advantage easily.The more important thing is because the present invention adopts the permanent magnetism drive to replace gear drive, therefore, contactless during transmission, nothing friction, lossless, operating noise is littler, longer service life.

Embodiment
A kind of high-power permanent magnet speed increasing box comprises housing 1, power shaft 2, output shaft 12, jack shaft 3, middle permanent magnetic wheels I 4 and middle permanent magnetic wheels II 10, and housing 1 is made up of supporting bracket 8, protecgulum 7 and bonnet 9, protecgulum 7 and bonnet 9 and supporting bracket 8 interference fit.Power shaft 2 is erected on supporting bracket 8 and the protecgulum 7 by zanjon bearing 6, and output shaft 12 is erected on supporting bracket 8 and the bonnet 9 by zanjon bearing 6, the dead in line of power shaft 2 and output shaft 12.The output of the input of power shaft 2 and output shaft 12 stretches out outside the housing.Input permanent magnetic wheels 5 is arranged in the housing 1, and is fixedly mounted on the power shaft 2; Output permanent magnetic wheels 11 is arranged in the housing 1, and is fixedly mounted on the output shaft 12.Even three jack shafts 3 that distribute around power shaft 2 and output shaft 12, jack shaft 3 is parallel with output shaft 12 with power shaft 2, and jack shaft 3 is erected between the protecgulum 7 and bonnet 9 of housing 1 by zanjon bearing 6.Certainly, the quantity of jack shaft 3 also can be two or four, even more.Permanent magnetic wheels II 10 in the middle of the permanent magnetic wheels I 4 and output is installed on each jack shaft 3 respectively in the middle of the input with input permanent magnetic wheels 5 and 11 transmissions of output permanent magnetic wheels, leaves air gap between two permanent magnetic wheels of transmission mutually, air gap is 1 millimeter.On middle permanent magnetic wheels I 4 or middle permanent magnetic wheels II 10, arrangement of clutch can also be installed.
Permanent magnetic wheels comprises carriage 14, the embedded permanent magnetism tile 13 that is installed in bracket surface that compresses, and permanent magnetism tile 13 is the number of pole-pairs setting.The speed increasing ratio of gearbox was at 1: 4～1: 50, and the permanent magnetism tile 13 number of pole-pairs beguines of permanent magnetic wheels distribute according to speed increasing ratio.The size of permanent magnetism tile 13 is according to the torque arithmetic of power shaft 2 with output shaft 12.
In the time of work, the power set that are connected with power shaft 2 with transmission of power to the input permanent magnetic wheels 5 on, middle permanent magnetic wheels I 4 by transmission with it is delivered to each jack shaft 3 and middle permanent magnetic wheels II 10 respectively again, again by with the output permanent magnetic wheels 11 of middle permanent magnetic wheels II 10 transmissions with transmission of power to output shaft 12.
Since each jack shaft 3 and middle permanent magnetic wheels I 4 and middle permanent magnetic wheels II 10 be evenly distributed on power shaft 2 and output shaft 12 around, power shaft 2 and output shaft 12 are stressed diametrically evenly, cancel out each other, and transmission does not contact, so gearbox noiselessness when running up, operates steadily, do not have the machinery wearing and tearing.In addition, because the number of pole-pairs amount of transmission simultaneously is more, relatively be suitable for big load work, it is big to be specially adapted to load variations such as wind-driven generator, the occasion that moment of torsion is big.
