Compared with prior art, technical scheme provided by the present invention has advantages below：Firstth, the present invention is using special
The non-maintaining integrated bearing of system, is not required to intermittent oiling, using special guard system, effectively prevents outside the grease in bearing
Let out, be not required to intermittent oiling and also can guarantee that grease is abundant in bearing, be effectively guaranteed the lubrication of bearing, eliminate customer care and delay
The time of fast device, save maintenance cost；Secondth, the resonance between vehicle and retarder is slowed down, the present invention is exempted from using special
Integrated bearing is safeguarded, axle directly runs through non-maintaining integrated bearing inner ring, realizes once mounting completion, has thoroughly overturned biography
The technique that retarder must be secondary or even repeatedly installed is put in system, is effectively guaranteed the axiality of retarder, so that energetically
Slow down the resonance problem between vehicle and retarder, make the more steady safety of vehicle traveling, i.e., using the one of special closed
Formula taper roll bearing, integrated bearing is directed through using an optical axis and is directly connected to the both ends of retarder, only need one
Procedure just installs bearing；3rd, its is simple in construction, easy for installation, solves the problems, such as process Installation, substantially increases
Installation effectiveness.
Brief description of the drawings
It can be obtained further by following detailed description of the invention and institute's accompanying drawings on the advantages and spirit of the present invention
Solution.
Fig. 1 is the structural representation of middle retarder provided by the present invention.

The combination of known technology identical other technologies is implemented.
, will be by all in order to clearly show that the structure and working method of the present invention in the explanation of specific examples below
Multidirectional word is described, but should by "front", "rear", "left", "right", " outer ", " interior ", " outside ", " inside ",
The Word Understandings such as " axial direction ", " radial direction " are not construed as word of limitation for convenience of term.
It is an object of the invention to provide a kind of middle retarder, realizes the non-maintaining of retarder, meanwhile, improve slow
The problem of resonance of device retarder and vehicle because caused by axiality is low is frequent.
1 describe specific embodiment of the invention in detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of middle retarder provided by the present invention.As shown in figure 1, in provided by the invention
Putting formula retarder includes shafting assembly, rotor assembly, field frame assembly；Wherein,
Field frame assembly includes：One upper stator disc 1, several top crowns 2,9, lower stator discs 11 of several coils,
Several bottom crowns 12 form；The top crown 2 is distributed by way of electric welding to be welded on upper stator disc 1, the bottom crown
12 are distributed by way of electric welding and are welded on lower stator disc 11；The upper and lower stator disc being welded is again by bolt pole 10
It is locked between two stator discs；Coil 9 is set on pole 10, then coil 9 is pressed on two stators by spring shim
Between disk；
Rotor assembly includes：Rotor 13, one after one preceding preceding shaft end pressure plate 8, one of the forward flange 6, one of rotor 3, one
