For up to this purpose, the utility model uses following technical scheme：
A kind of mounting structure of the non-shaft end grounding carbon brush of motor and encoder, it includes motor shaft, the motor shaft
It is non-go out shaft end be provided with outside bearing, the bearing bearing end cover be set, wherein, the motor shaft it is non-go out shaft end outside be fixed with
Be provided with grounding carbon brush on motor shaft in grounding carbon brush support, the grounding carbon brush support, the motor shaft it is non-go out shaft end
End face on be provided with connecting shaft, the connecting shaft is stretched out the grounding carbon brush support and set, and the end of the connecting shaft is consolidated
Surely there is encoder.
Especially, be provided with earth stud in the grounding carbon brush support, the grounding carbon brush and the earth stud it
Between electrically connected by wire.
Especially, the connecting shaft is coaxially disposed with the motor shaft.
Especially, the motor shaft it is non-go out shaft end end face on offer fixing groove, the connection shaft section is T-shape
Structure, its head is fixed in the fixing groove by fixing bolt.
Especially, it is provided with sealing ring between the bearing end cover and the motor shaft.
Especially, the grounding carbon brush support is fixed on the bearing end cover by fixing bolt.
The beneficial effects of the utility model are, compared with prior art the non-shaft end grounding carbon brush of the motor and coding
The mounting structure of device is not only simple in structure compact, it is easy to install；And coaxial precision height, accurately, structure easy for installation is tight for action
