Compensation and short-circuit protection, impact resistance, vibration resistance.
At present, the structure of installing encoders in the prior art for motor is mainly used in electric machine main shaft more than encoder axle
Situation, but for ting model motor, electric machine main shaft be less than encoder axle motor, existing structure of installing encoders is then
The installation of encoder can not be realized.
Utility model content
The purpose of this utility model is to provide a kind of structure of installing encoders for motor, to solve prior art
In can not realize for electric machine main shaft be less than encoder axle motor carry out encoder installation the problem of.
For up to this purpose, the utility model uses following technical scheme：
A kind of structure of installing encoders for motor, it includes electric machine main shaft and electric motor end cap, the electric machine main shaft
Bearing is provided between the electric motor end cap, wherein, the end of the electric machine main shaft is fixed with connecting shaft, the connecting shaft
It is fixed with outside regular coding device, the encoder on encoder protective cover, the encoder protective cover and is provided with encoder wiring
Box, the lead-out wire of the encoder accesses the encoder wiring box.
Especially, the both sides of the bearing are respectively arranged with internal bearing cover and bearing end cover.
Especially, correspondence offers several through holes in the connecting shaft, is opened up corresponding to the end of the electric machine main shaft
There is tapped blind hole, fixing bolt lock onto in the tapped blind hole through the through hole connecting shaft being connected to the electric machine main shaft
On.
Especially, being provided with the outside of the encoder prevents the shaft block ring of its axial float.
Especially, the end face of the electric machine main shaft offers locating slot, is provided with corresponding to the end in the connecting shaft
Locating dowel, the locating dowel is inserted in the locating slot, is easy to the installation of connecting shaft.
The beneficial effects of the utility model are that the structure of installing encoders for motor increases compared with prior art
If connecting shaft, the connection of encoder and electric machine main shaft is realized by connecting shaft, realizes and is less than encoder axle in electric machine main shaft
Encoder is installed on motor, is not only simple in structure compact, it is easy to install；And install reliable and stable, applicability is wide, degree of protection
It is high.
