Abstract
The utility model discloses a kind of closing wound motor collector rings, it includes collector shell, sleeve, slip ring and brushgear, and the outside of collector shell is equipped with sealing cover, and one end of sleeve is equipped with fan；The bottom of collector shell is equipped with carbon powder collecting device below slip ring and brushgear, and the side wall of carbon powder collecting device is equipped with filter screen.When the utility model at work, motor drives current collection ring sleeve, slip ring and fan to rotate together, fan rotates generated wind to hollow cooler, hot-air in collector ring is subjected to heat exchange with hollow cooler, it carries out the cold air after heat exchange and uniformly blows to slip ring and brushgear to make slip ring uniform decrease in temperature, heat caused by slip ring carries out heat exchange by hollow cooler, hollow cooler completes heat exchange with outer ventilation circuit, realizes the ventilation and heat exchange of closing wound motor collector ring.Short circuit between the setting of carbon powder collecting device avoids carbon dust from causing slip ring simultaneously.
Description
Technical field
The utility model is related to motor device technical field, specifically a kind of closing wound motor collector ring.
Background technology
Wound motor installs collector ring in non-shaft stretching end, and effect is to be drawn rotor current by slip ring and carbon brush configuration
Go out into rotor junction box, rotor current is connected to by water resistance starting cabinet by rotor junction box again to realize that the soft of motor is opened
It is dynamic.Closing winding-type three-phase asynchronous motor traditional approach is：Motor body is closed, and current collection loop section is open-type, electricity
Machine is integrally not up to totally-enclosed form；For total utilization of PCA project and outlet key project motor, motor integral protection
Grade reaches IP54, therefore motor collecting ring part must be designed to totally-enclosed form.
The internal wind path of collector ring ventilation form point and external wind path two parts are closed, it is different from collector ring wind path is opened, it opens
It is that hot inside air directly carries out heat exchange with outside motor ambient air to open collector ring draft type, reaches cooling collector ring
Purpose；Closing collector ring is completely enclosed in collector ring cavity, is not exchanged with extraneous air, is avoided periphery dust pollution, is solved
It has determined since dust pollution causes the generation of short circuit accident between slip ring.But enclosed type collector ring ventilation and heat performance is poor,
The problem of slip ring temperature unevenness is susceptible in operational process, collector ring temperature is higher, influences the normal operation of motor；In addition by
It is completely enclosed in closing collector ring, if the carbon dust of carbon brush abrasion does not collect processing, be easy to cause the hair of short circuit accident between slip ring
It is raw, affect the normal operation of motor.
Utility model content
The purpose of this utility model is to provide a kind of closing wound motor collector ring, to solve the ventilation of closing collector ring not
Freely, slip ring is susceptible to temperature unevenness in operational process, and carbon dust fails to collect, the problem of be easy to causeing short circuit accident between slip ring.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of closing wound motor collector ring, it includes collector shell, sleeve and slip ring on armature spindle, is slided
The outside of ring is equipped with brushgear, which is fixed on collector shell, and the outside of collector shell is equipped with sealing cover, described
One end of sleeve is equipped with fan；Collector shell bottom below slip ring and carbon brush configuration is equipped with carbon powder collecting device, and carbon dust is received
The side wall of acquisition means is equipped with filter screen.
Preferably, the top of the collector shell is equipped with air-air cooler.
When the utility model at work, after rotor rotates, current collection ring sleeve and slip ring is driven to rotate together, sleeve
Fan is driven to rotate simultaneously, wind caused by fan rotation makes slip ring uniform decrease in temperature, while produced by slip ring to bushing core
Heat heat exchange is carried out by air-air cooler, air-air cooler and outer ventilation circuit complete heat exchange, realize closing around
The ventilation and heat exchange of linear motor collector ring.
The utility model is in carbon powder collecting device of the brush-holder bottom provided with top opening, collector shell inner cavity
Air passes through the filtering of carbon powder collecting device, and carbon dust is collected processing, avoids accumulation of the dust in collector ring, will not cause
The generation of short circuit accident between slip ring.
The utility model can suitably increase the outer diameter of fan, to increase ventilation quantity.
The beneficial effects of the utility model are：
（1）The utility model installs fan in one end of sleeve, wind caused by fan rotation to air-air cooler,
The hot-air of slip ring intracavitary and air-air cooler are subjected to heat exchange, carry out the cold air after heat exchange uniformly blow to slip ring and
Brushgear, profit reduce slip ring temperature；
（2）Carbon powder filter of the hot-air through collector shell bottom after heat exchange filters the carbon dust being wherein mingled with,
Accumulation of the carbon dust in collector ring is avoided, short circuit accident will not occur between slip ring, avoids causing environmental pollution, is improved
The reliability service of closed wound motor collector ring；Carbon powder filter is quick detachable simultaneously, replaces.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of closing wound motor collector ring, it includes collector shell 7, sleeve 2 and slip ring on armature spindle
3, the outside of slip ring 3 is equipped with brushgear 5, and brush is opposite with the center line of slip ring 3 just, and brushgear 5 is fixed on collector shell 7
On internal brush carriage, the outside of collector shell 7 is equipped with sealing cover 8, and one end of sleeve 2 is equipped with fan 4；Slip ring 3 and electricity
The bottom of 5 lower section collector shell of brush device is equipped with carbon powder collecting device 1, and the side wall of carbon powder collecting device 1 is equipped with filter screen.
The top of collector shell 7 is equipped with air-air cooler 6.
When the utility model at work, after rotor rotates, current collection ring sleeve 2 and slip ring 3 is driven to rotate together, covered
Cylinder 2 drives fan 4 to rotate simultaneously, fan 4 rotate caused by wind to air-air cooler 6, by collector ring hot-air with
Air-air cooler carries out heat exchange, carries out the cold air after heat exchange and uniformly blows to slip ring 3 and brushgear 5, to make slip ring
3 uniform decrease in temperature, heat caused by slip ring 3 carry out heat exchange by air-air cooler 6, and air-air cooler 6 and outer ventilation circuit are complete
At heat exchange, the ventilation and heat exchange of closing wound motor collector ring are realized.
