The size of outer occupied space, speed changer is smaller.
The peripheral teeth tooth rim of same shaft gear be uniformly arranged there are two, three or four concentric electric stators.
The electricity stator is annulus.In this way, the magnetic force of electric stator and armature residual gap is more stable when electric stator is circular ring shape
And magnetic force is relatively large.
The key slider disk tooth tooth form is rectangle or bullet shaped or sector or back taper or trapezoidal or triangle.In this way,
It is engaged securely between key slider and shaft gear, reliability is higher.
The mesoporous hole depth of the key slider is greater than 8mm.In this way, the stable structure of key slider, high reliablity.
It is fixed between the key slider and armature by attachment device.Attachment device include but is not limited to be glued or welding or
Screw or riveting device.In this way, being firmly combined between key slider and armature, and cost is relatively low.
The electricity stator is fixed on gear box casing by support frame.In this way, electric stator and gear box casing fix tightly
Gu and and electric stator can set specific location according to actual needs.
One support frame as described above supports 1,2 or multiple electric stators.In this way, can reduce the quantity of support frame, in turn
The corresponding weight and size for reducing speed changer.
The electric current or/and voltage of the electricity stator are controllable.In this way, the current or voltage of electric stator can be controlled as needed,
And then the movement of control key slider.
The single side of the key slider is provided with disk tooth.The electric shift component include a key slider and with key slider
An opposite shaft gear of disk tooth.In this way, when the series of speed changer is less, the key slider that disk tooth is arranged in single side can be with
Reduce speed changer cost, size and weight.
The two-sided of the key slider is provided with disk tooth.The electric shift component includes a key slider and two shafts
Gear, key slider are located between two shaft gears.In this way, disk is arranged compared to single side when speed changer needs series more
The key slider of face tooth, the cost of speed changer is lower, and smaller, weight is lighter.
The axis includes input shaft and output shaft, and electric shift component is arranged on input shaft or/and output shaft.
The axis includes input shaft, output shaft and jackshaft, the setting of electric shift component input shaft, output shaft and in
Between axis any axis or a few axis on.It is arranged on different axis in this way, electric shift component can according to need, maximized benefit
With the space of speed changer, reduce gearbox weight and size.
The present invention is and axially opposing with the armature on key slider by the way that electric stator to be fixed on gear box casing
Setting, in working condition and off working state, maintains gap between electric stator and shaft gear, key slider and armature,
So that electric gear shift(ing) have it is stable, reliable, safety is good, compact-sized, power consumption is small, size is small, it is at low cost,
The advantages that wearing small and long service life.
