Detailed description of the invention
The utility model explains orally the structure of most preferred embodiment of the present utility model in detail with accompanying drawing with the following Examples.
Embodiment of the present utility model shown in accompanying drawing 1 is an agitating device, this device by: as the drive motors (also can add deceleration device) 1 of power source, for connecting the second magnet rotor axle 7 of stirrer paddle 8, formation such as maintenance sealing drum 5 grade.
Thin portion of the present utility model structure is see accompanying drawing 2, wherein: be combined with outer rotor flange 14 as on the first rotor axle 3 of driving shaft with key, outside rotor flange 14 is fixedly installed the first Magnetic drive device 13 in tubular with bolt, as the second magnet rotor axle 7 of driven shaft being fixedly installed the second Magnetic drive device 12 that be positioned at tubular first Magnetic drive device corresponding with the first Magnetic drive device 13.Locate with the second bearing 16 between the bearing housing of the second magnet rotor axle 7 and gear mechanism housing, the second bearing is sliding bearing as seen from Figure 2.The bearing housing of simultaneously housing is also fixed with the separation sleeve 11 made with permeability magnetic material, by separation sleeve 11 by completely isolated between the first magnet rotor and the second magnet rotor.The inner edge of the free end 15 of the front end of separation sleeve 11 is located with the front end of the 4th bearing and the second magnet rotor axle, and also show from Fig. 2, the 4th bearing is also sliding bearing; The outer rim of the free end 15 of separation sleeve 11 front end and the interior intermarginal of outer rotor flange 14 pass through the 3rd bearing 10 and locate.Located by clutch shaft bearing 9 between the outer rim of outer rotor flange 14 and device case bracing frame 2.Visible by accompanying drawing 2: in the present embodiment, clutch shaft bearing 9, second bearing 10 all have employed rolling bearing, and first, third and fourth bearing be substantially in same axial location, the present embodiment adopts such structure can make to act on completely on the housing of device through the power of the second magnet rotor axle transmission, therefore can overcome the deficiencies in the prior art completely.
It inner to be communicated with being stirred in system by separation sleeve in the present embodiment, separation sleeve outside then completely and to be stirred system isolated.Therefore not conducting completely between first, second magnet rotor.But due to the magnetic field existed between first, second Magnetic drive element, when driving deceleration device 1 to drive the first magnet rotor axle 3 to rotate, the second magnet rotor axle 7 can produce synchronous rotation by the coupling of magnetic force, achieves non contact transmission moment of torsion.And when first, second magnet rotor axle is rotated by the coupled synchronization of magnetic force, because magnetic force skew causes the second magnet rotor axle yaw, or during because of load end generation torsion, its power produced is transmitted on device case by the first, third and fourth bearing, finally offset in system, the bearing therefore thoroughly overcoming prior art sweeps thorax, the second magnet rotor axle and spacer collision problem.Be delivered on rolling bearing 10 by the location of sliding bearing 6, then be delivered on rolling bearing 9, be supported on the tank body of stirring system by support arm 2; Thus any Relative friction completely eliminated between inside and outside magnet rotor and spacer and stir bearing and sweep thorax, thoroughly solve the insurmountable technical barrier of prior art, therefore can not deposit the disadvantage such as ubiquitous spacer wearing and tearing, bearing damage, seal break-off in the prior art completely.Use through reality shows, the service life of the present embodiment can reach 20000 hours, far away higher than the time that prior art can reach.
