Outside be provided with external jacket, the external jacket is located at the outside of neck and male cooperation.
The utility model ensures that the beneficial effect of the reductor attachment structure of motor drive shaft centering is, during use, connection
Input shaft by the clamping force of external jacket, using the principles of three points centering, three bar grooves are cut on input shaft, are pressed from both sides using external jacket
Tightly, three groups of necks are made with, toward center stressed, being guarantee center all the time in the process of clamping motor drive shaft, making at raised cooperation
During, radial force is overcome so that transmission is more steady, adds the precision of output.
It is that the neck, raised cross section are T-shaped or trapezoidal as further improvement of the utility model
Shape.Using the setting of this kind of structure so that the grafting of motor drive shaft and input shaft bore is more steady, further increases output essence
Degree.
Preferably, the external jacket is made up of the first fastener, the second fastener, one end and the second fastener of first fastener
One end connected by axis of rotation, the other end of the other end and the second fastener of first fastener is bolted, knot
Structure is simple, easy for installation.
Preferably, the outside of the input shaft is provided with a circle groove, and the outer clip is set in groove.Avoid additional
Set can move on input shaft.
It is as further improvement of the utility model, because input shaft runs at high speed, the bearing of supporting input shaft rotation
The temperature at place can uprise, and can influence the life-span of bearing, and bearing can be damaged, in order to prevent the appearance of this phenomenon, the input shaft
On be provided with reduce temperature cooling device.
Preferably, the cooling device includes tube-axial fan, centrifugal fan, the tube-axial fan, centrifugal wind
Fan is arranged on input shaft, and the tube-axial fan is located at the outside of centrifugal fan.The temperature at input shaft can quickly be reduced
Degree.
