The utility model has the advantages that: this motor of the utility model, its main shaft adopts the bearing structure of integral type, and unlike conventional art, is the multi-segment structure of mutual split, and electric machine structure is simplified more, is convenient to assembling and the maintenance work of motor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is the structural representation of this inner-rotor-type wheel hub motor of the utility model embodiment;
Wherein: 1-main shaft, 2-clutch shaft bearing, 3-lining, 4-clutch, 5-takes turns hub shell, 6-planetary gear, 7-ring gear, 8-sun gear, 9-rotor field spider, 10-rotor, 11-magnet steel, 12-stator, 13-stator support, 14-wheel hub end housing, 15-the 3rd bearing, 16-the second bearing, 17-planet axis, 18-the 4th bearing.
Embodiment
Fig. 1 has shown a specific embodiment of this inner-rotor-type wheel hub motor of the utility model, the same with conventional art, it also comprises main shaft 1, on main shaft 1, by clutch shaft bearing 2 rotations, be equipped with wheel hub shell 5, on main shaft 1, by the second bearing 16 rotations, be equipped with wheel hub end housing 14, and wheel hub shell 5 and wheel hub end housing 14 are fixed together by bolt (not marking in figure), in wheel hub shell 5, be provided with rotor 10 and stator 12, adopt internal rotor outer stator structure, and rotor 10 is in transmission connection by planetary reducer and the described hub shell 5 of taking turns.
The key improvements of the present embodiment is: described main shaft 1 is a whole axis, and main shaft 1 is a monolithic construction, and unlike conventional art, is divided into three separate axle heads.One end of this main shaft 1 passes described hub shell 5 outsides of taking turns, and the other end passes described outside of taking turns hub shell 5.
In the present embodiment, described main shaft 1 adopts the bearing structure of integral type, and electric machine structure is simplified more, is convenient to assembling and the maintenance work of motor.Although this structure makes motor number than less than normal, can optimize motor performance by changing motor magnetic circuit structure, overcome number than defect less than normal.
Described rotor 10 is arranged on main shaft 1 by a rotor field spider 9, is specially: rotor 10 is fixed on rotor field spider 9, and rotor field spider 9 is assemblied on described main shaft 1 by two the 3rd bearing 15 rotations.
Described stator 12 is arranged on main shaft 1 by a stator support 13, is specially: stator 12 is colded pressing and is fixed on stator support 13, and stator support 13 is fixed on described main shaft 1 by key pin.
In the present embodiment, the detailed structure of described planetary reducer can be with reference to shown in Fig. 1, it comprises the sun gear 8 fixing with rotor field spider 9, with several planetary gears 6 of 8 engagements of gear too, be fixed on clutch 4 on main shaft 1, be fixed on the some planet axis 17 on clutch 4 and be fixed on (or on wheel hub end housing 13) on wheel hub shell 5 and with the ring gear 7 of each planetary gear 6 engagements, described planetary gear 6 is assemblied in described planet axis 17 by two the 4th bearings 18 rotations.In this example, described planetary gear 6 is provided with three altogether, in Fig. 1, only shows one of them.Corresponding, the quantity of described planet axis 17 is three, only shows wherein one in Fig. 1.
