Geared system 400, its structure, operation principle and the technique effect of generation may be referred to the corresponding contents in embodiment four, this
Place is not described in detail.
Motor 51 is mainly to provide power, and motor 51 is fixed in frame 41, passes through sealing between motor 51 and frame 41
Circle sealing.The output shaft of motor 51 is connected with the input of main shaft 11, during work, and the drive shaft 11 of motor 51 is rotated.
The output end of motor 51 is with the input of main shaft 11 by spline housing 52, and the inner surface of spline housing 52 is provided with internal tooth,
The output end of motor 51 is equipped with external tooth with the input of main shaft 11, so, not only easy to connect, and uniform force, transmission
It is stable.Certainly, it can also be connected between the input of the output end of motor 51 and main shaft 11 by shaft coupling, conventional shaft coupling
Flexible shaft coupling, diaphragm coupling, bellows coupling, oldham coupling, plum coupling and positive coupling etc..It is preferred that
, yielding coupling can be used, yielding coupling has certain buffering, the effect of damping.
The dumper also includes wheel rim 53, and wheel rim 53 is fixed on the outside of hub body 31 and being capable of synchronous axial system.
The output end of main shaft 11 is also closed by end cap 54, and end cap 54 is fixed on primary planet carrier 122.
Motor 51, frame 41, hub body 31, torque tube 32, primary planet carrier 122 and end cap 54 define one jointly
Seal cavity, primary transmission component 12 and secondary transmission component 13 are located in seal cavity.So.Prevent from granular substance
Or other debris enter in primary transmission component 12 and secondary transmission component 13, substantially increase operating mode.In seal cavity also
Equipped with lubricating oil, lubricating oil is without the full seal cavity of filling, it becomes possible to which the transmission component in sealing cavity is lubricated.Because
When dumper works, primary transmission component 12 can make on all devices in lubricating oil splash to sealing cavity so that whole
Device lubrication is good.
The dumper is rational in infrastructure, high lubricating effect, large carrying capacity, transmission power big, transmission efficiency, operation are flat
Surely, larger gearratio can be realized.
The preferred embodiment of the present invention is the foregoing is only, is not intended to limit the invention, for this area
For technical staff, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made is any
Modification, equivalent substitution, improvement etc., should be included in the scope of the protection.
