Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Referring to Fig. 1~4, the utility model, which provides, can reduce nuclear submarine rudder arrangement equipment gear oil pump unit noise
Shaft coupling, including driving shaft 1, driven shaft 3 and internal tooth casing 2.
The effect of shaft coupling is exactly that the power output of driving shaft 1 is play a part of to be coupled, be driven, based on this to driven shaft 3
Purpose, the end of driving shaft 1 of the present utility model are both provided with external gear 6 with the end of driven shaft 3；The inside of internal tooth casing 2 is set
There is internal gear 5, wherein internal gear 5 is equal with the base pitch of external gear 6, and modulus is identical, such internal gear and external gear
Just can be at a fully engaged, make parallel offset, angular deviation and the axial deviation of driving shaft 1 and driven shaft 3 reduce, realize transmission；
