On can be conveniently being connected to motor fan cover with collecting ring mechanism, do not influence motor normal operating promptly, again safe, support reliably, fixed external collecting ring mechanism, fundamentally has solved the problem of the unable external collecting ring mechanism of lug connection of large -scale motor fan cover to the manufacturing degree of difficulty and cost have been reduced. The utility model discloses simple structure, convenient to use, the effect is obvious.
Description
Technical field
The utility model is related to a kind of motor fan housing device, the external collector ring motor fan housing of particularly a kind of stable support
Device, belongs to Machine Design manufacturing technology field.
Background technology
The winding rotor motor of external collector ring, is to be placed in end cap wind using collector ring as auxiliary accessories on motor
Fan outside, from from surface structure globality not as the structure of " built-in " collector ring it is attractive in appearance, but the advantage of " external " collector ring is
Collector ring is kept apart with winding, is effectively prevented carbon brush dust pollution winding overhang, is extended the insulation life of winding, improve
The reliability of motor, and it is conveniently replaceable carbon brush.Existing " external " collector ring winding rotor motor, because which belongs to micro-machine,
The current collection ring mechanism for supporting fixation external is just enough to the fan housing of aluminium alloy only, but for large-size machine, it is large-scale due to which
Fan housing wall is relatively thin, it is impossible to be directly connected to external current collection ring mechanism, if but use heavy wall fan housing instead, necessarily increase manufacture difficulty and system
This, and long the production cycle is caused, and is inconvenient to keep in repair, changed.It is therefore desirable to being improved to prior art.
The content of the invention
For solving the problems, such as that existing large-size machine cannot be directly connected to external current collection ring mechanism, the utility model provides a kind of
The motor fan housing device of external collector ring is supported stably.
The utility model is completed by following technical proposal：A kind of motor fan housing device for stably supporting external collector ring,
Including the fan housing located at motor tail end, and pass through fan housing the electric machine main shaft for extending outwardly, it is characterised in that electric machine main shaft
Elongated end is provided with support ring flat-plate by rolling bearing, is connected with current collection ring mechanism on the outside of the support ring flat-plate, and inner side is by connection
Plate is connected with fan housing, will pass through support ring plate and roller bearings current collection ring mechanism on electric machine main shaft, then by even
To supporting ring flat-plate and fan housing to position, fishplate bar solves the problems, such as that large-scale fan housing is difficult to supported collection Electric ring machine structure.
The support ring flat-plate is circular slab, supports the centre of ring flat-plate to be provided with hole circlip groove, and rolling bearing is placed in this
In the circlip groove of hole, electric machine main shaft is engaged with rolling bearing, so as to ring flat-plate will be supported to be supported on electric machine main shaft.
It is described support ring flat-plate outer rim be interval with multiple through holes, be provided with bolt and nut or screw in through hole, so as to it is right
The protective cover of the current collection ring mechanism answered, current collection ring mechanism are connected.
The connecting plate is set to straight panel of the two ends with flap, is respectively equipped with through hole on the flap at two ends, is provided with spiral shell in through hole
Bolt and nut, connect fan housing and current collection ring mechanism respectively will pass through connecting plate, so as to complete determining for fan housing and current collection ring mechanism
Position.
The flap bearing of trend at the connecting plate two ends is contrary or identical, to make connecting plate be fixed on fan housing and support ring
On plate.
The connecting plate is set to polylith.
The utility model has following advantages and effect：Using such scheme, it is convenient to which current collection ring mechanism is connected to
On motor fan housing, i.e., motor is not affected normally to run, and reliably and securely support, the external current collection ring mechanism of fixation, fundamentally
Solve the problems, such as that large-size machine fan housing cannot be directly connected to external current collection ring mechanism, and reduce manufacture difficulty and cost.
The utility model simple structure, easy to use, effect is obvious.
