Description
Technical field
The utility model relates to a kind of cooling body of interior slip ring motor, specifically is used for the cooling of interior slip ring motor, belongs to the motor technology field.
Background technology
Motor is a kind of equipment that converts electric energy to mechanical energy.It is to utilize hot-wire coil (namely stator winding) to produce rotating magnetic field and act on the closed aluminium frame of rotor squirrel-cage formula to form magnetoelectricity dynamic rotation moment of torsion.Motor is by using the power supply difference to be divided into DC motor and alternating current motor, and the motor major part in the electric power system is alternating current machine, can be synchronous machine or asynchronous machine (motor stator rotational speed of magnetic field and rotor rotating speed do not keep same leg speed).Motor mainly is comprised of stator and rotor, and the direction of electrified wire stressed motion in magnetic field is relevant with magnetic induction line (magnetic direction) direction with the sense of current.The motor operation principle be magnetic field to the stressed effect of electric current, motor is rotated.The advantages such as that threephase asynchronous has is simple in structure, be easy to control, efficient is high, cost is low and power is large are widely used in the modern various plant equipment.
All the time, the environment for use of motor is very complicated, all uses motor such as traditional industries such as colliery, mine, cement.General cement industry uses motor more.And the slip ring structure of motor generally is designed to outer slip ring, slip ring degree of protection IP23.The motor size of outer slip ring structure is relatively long, and the local influence little in some spaces used.In addition, some special operation condition needs motor to make the Double shaft-extension action, and conveniently to connect auxiliary biography equipment, this moment, motor need be made interior slip ring structure.Slip ring structure is to be provided with fan in the slip ring chamber in the motor routine, wind path in forming, and the difficult discharge such as dust easily causes Short circuit, blows out even burns out, and directly affects the production of whole production line.For this reason, interior slip-ring motor needs a kind of new cooling body to satisfy some special environments for use.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of cooling body of interior slip ring motor is provided, and is simple in structure, and good cooling results has improved the scope of application of interior slip ring motor.
The technical scheme that provides according to the utility model, the cooling body of interior slip ring motor comprises brush holder support, slip ring and motor casing, brush holder support is installed in the motor casing, brush holder support outer ring connection slip ring, it is characterized in that: also comprise cooler of electric motor, wind-collecting cover, shutter and baffle plate, cooler of electric motor is fixed on the motor casing, and cooler of electric motor is connected with wind-collecting cover.Described wind-collecting cover is fixed on the motor casing, and the wind-collecting cover downside is to slip ring.Described motor casing inside bottom fixed dam is bolted shutter on the motor housing of baffle plate both sides.
Described wind-collecting cover is up big and down small funnel-shaped structure.Described baffle plate is herringbone.
Compared with the prior art the utility model has the following advantages: the utility model is simple, compact and reasonable for structure; Good cooling results has improved the scope of application of interior slip ring motor; The motor internal carbon dust can periodic cleaning.

Embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
Shown in Fig. 1 ~ 2, the utility model mainly comprises cooler of electric motor 1, wind-collecting cover 2, brush holder support 3, slip ring 4, shutter 5, baffle plate 6 and motor casing 7.
Motor casing 7 interior installation brush holder supports 3, brush holder support 3 outer ring connection slip rings 4.Cooler of electric motor 1 is fixed on the motor casing 7, and cooler of electric motor 1 is connected with wind-collecting cover 2.Described wind-collecting cover 2 is fixed on the motor casing 7, and wind-collecting cover 2 is up big and down small funnel-shaped structure, and wind-collecting cover 2 downsides are to slip ring 4.Described motor casing 7 inside bottom are fixed lambdoid baffle plate 6, are bolted shutter 5 on the motor housing 7 of baffle plate 6 both sides.
Operation principle of the present utility model is: during machine operation, draw cold wind by cooler of electric motor 1 and enter wind-collecting cover 2.Wind-collecting cover 2 is funnel-shaped structure, can concentrate compression to cold wind, and the cold wind after the compression enters slip ring 4 the insides, directly slip ring 4 is taken away because of fricative heat, blows out from the shutter 5 of bottom.Remain that like this hot blast goes out, cold wind advances, effectively reduced the temperature rise in the slip ring chamber.Motor casing 7 bottom fixed dams 6, baffle plate 6 are the low herringbone structures in middle high two ends, play guiding wind direction and carbon dust trend.The carbon dust that slip ring 4 is discharged, only need regularly be opened shutter 5 and clear up and get final product shutter 5 other accumulations along baffle plate 6, the unsafe factor such as can eliminate effectively that the slip ring that causes the carbon dust accumulation to cause because of the untimely cleaning of carbon dust is blown out.
Above-described only is the preferred implementation of the utility model patent, and the utility model patent is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the spirit that does not break away from the utility model patent and design, all should think to be included within the protection range of the utility model patent.
