Description
Technical field
A kind of inside labyrinth dustproof construction of high speed coiling motor is the utility model is related to, is used especially suitable for metallurgical place
High rotating speed winding rotor motor.
Background technology
The rotor three-phase winding of winding asynchronous motor connects into star, and three terminal wires are connected on machine shaft
On three copper slip rings, it is connected by one group of brush with external circuit.Winding asynchronous motor before activation can be in rotor loop
Outer string starts resistance, and so one side can reduce starting current, on the other hand can increase and initial start up torque, when sealing in certain
During one suitable resistance, moreover it is possible to motor is started with its torque capacity T.Because the rotor inline of winding asynchronous motor is suitable
Resistance, can not only reduce starting current, and detent torque can be increased, thus, it is desirable to the torque of startup is big or starts
Frequently manufacturing machine often uses wound rotor asynchronous motor.Required in some specific large scale equipments using high-revolving coiling electricity
Machine, but because motor rotary speed is fast, the linear speed that brush is walked on collector ring is higher, causes brush wear serious, produces big
Dust is measured, has had a strong impact on motor performance.The conventional high rotating speed winding asynchronous motor internal structure of existing market is shown in attached
Fig. 1, existing deficiency has this kind of structural electromotor in use：1st, because brush material is using graphite or electrographite, electricity
For machine in operation process, brush produces a large amount of dust with collector ring high speed rotary grinding, easily causes slip ring because of dust accumulation mistake
It is form short circuit, blow out, even burn out more；The 2nd, stator dust board and rotor dust board are housed between end cap and motor stator, it is fixed
Sub- dust board is fixed on end cap, and for rotor dust board on machine shaft, rotor dust board collective effect stops that dust enters
Enter inside machine winding, because rotor dust board rotates with rotor, gap between two dust boards be present, dust with gap very
Motor internal is easily accessible, reduces motor insulation；3rd, because end cap is closed, no dust outlet, dust bulk deposition is in end cap
Intracavitary, motor operating produce blast, dust can be driven to be danced in the air everywhere in end cap intracavitary, so as to influence motor performance.
The content of the invention
The purpose of this utility model is, for the deficiency present in existing winding asynchronous motor, particularly at a high speed around
Line motor and the inside labyrinth dustproof construction of a kind of high speed coiling motor proposed.
The technical solution of the utility model：The inside labyrinth dustproof construction of high speed coiling motor of the present utility model includes electricity
Machine stator, end cap, brush, collector ring, rotor, rotor dust board, stator dust board, its stator dust board are consolidated by bolt
It is scheduled on end cap, rotor dust board is socketed in the rotating shaft of rotor, and rotor dust board is with stator dust board with labyrinth type knot
Structure gap is connected, and a dust-exhausting port is opened in end cap bottom, installs slidingtype dust discharge drawer additional on the outside of dust-exhausting port.
Described slidingtype dust discharge drawer includes being fixed on the drawer guideway on end cap and the storage on drawer guideway
Dirt drawer, drawer guideway outer end installation magnet, the effect of sucking is built to irony storage dirt drawer.
There are annular groove or boss in described rotor dust board outer ring, in stator dust board inner ring and rotor dust board outer ring
Overlapping has annular boss or groove to be matched with described annular groove or boss, forms maze-type structure gap and coordinates.
Effect of the present utility model is：1st, brush material is changed to metallic graphite carbon, collector ring by original graphite/electrographite
Upper copper slip ring material is changed to silizin (due to brush metal-containing powders, need to increase the wearability of slip ring simultaneously) by basis brass,
It can largely be reduced by dust caused by the change brush wear of material, controlled from source, and reduce personnel more
The number of brush is changed, reduces maintenance cost.
2nd, rotor dust board is changed to maze-type structure, is coordinated between two dust boards by multiple face, can be with effectively
Dust is prevented to enter motor internal, dust gear in another head end cover.
3rd, a dust-exhausting port is opened in end cap bottom, installs specially designed slidingtype dust discharge drawer additional at dust-exhausting port, this takes out
Drawer can prevent the dust of outer working environment, greasy dirt from entering end cap, and staff can be facilitated easily to exclude at any time in end cap again
The dust of deposition.
