Axle is simultaneously screwed onto on the bracket flange, for forming sealing between tank body and agitating shaft；The body of the bracket flange is
Tubular, its sidewall symmetry is provided with bar hole, for manually operating with；The agitating shaft is provided with shaft coupling away from agitator arm end
I；Shaft coupling II is installed on the output shaft of the drive device；The shaft coupling I and shaft coupling II are supported the use；The shaft coupling
Concentric locking collar is installed between device I, II；The concentric locking collar body be tubular, its body two ends be formed with laterally respectively with it is described
The mounting seat that shaft coupling I, shaft coupling II match；The axial length of the concentric locking collar is long more than the axial direction of the mechanical seal
Degree.
It is preferred that, the external diameter of the internal diameter less than agitating shaft of the concentric locking collar body.
It is preferred that, the drive device is permanent magnetism velocity modulation electric engine, and traditional drive part mostly uses reductor and motor, according to
By belt pulley and belt transmission, it is fixedly connected by location-plate, connection member is more, the bad guarantee of precision, and part is more
Fault rate is higher, and the function of above-mentioned all parts is contained in permanent magnetic speed-adjusting motor integrating, reduces the fault rate of equipment.
It is preferred that, described concentric locking collar one end is formed with boss, and the other end forms fluted, groove, boss shape respectively with
The structure of two ends shaft coupling matches.
It is preferred that, the concentric locking collar coordinates seam tolerance in 0.001-0.1mm with shaft coupling I, II；Use lathe in machining
Rough turn and smart car, inner hole size uses numerical control machining center bore hole, it is ensured that concentricity is within 0.01mm.
It is preferred that, the end face of described shaft coupling I, II realizes axially position by bolt and cushion block.
The utility model has advantages below：
1) concentric locking collar is installed, this concentric locking collar need to be only pulled down when mechanical seal is changed, so that it may mechanical seal is moved from axle
Go out, compared with dismounting drive part, operationally between it is upper save more than 50%, greatly reduce labour intensity, and avoid
Because dismounting problem is to the damage caused by equipment, the service life of extension device.
2) length of agitating shaft is shortened, agitating shaft is reduced because amount of deflection causes the risk of flexural deformation, extension uses the longevity
Life.
