Technical field
The utility model relates to the coiling electric motor manufacturing in the field of motor manufacturing, and especially a kind of coiling electric motor is with the slip ring cooling structure that ventilates.
Background technology
Slip ring and carbon brush are very important parts of coiling electric motor, also are easy failed component in the coiling electric motor.And slip ring and carbon brush major failure show as more that slip ring is overheated, the carbon brush slip-ring sparking, the short circuit of carbon distribution powder is creepage etc., and the main cause of these faults is slip ring and the good ventilation cooling system of carbon brush neither one.
Chinese patent ZL200810039652.0 discloses a kind of big-and-middle-sized coiling electric motor slip ring novel structure; A fan that is specifically designed to the slip ring cooling is installed in the outer end of outermost slip ring, can increases the cooling at slip ring place, both can reduce the carbon dust adhesion amount on the slip ring through the slip ring fan has been installed; Can also reduce the temperature rise of slip ring; Improved the stability of slip ring in running greatly, but because carbon dust is not easy discharge, and fly upward in inside through fan; Cause creepage short circuit easily, improved the incidence of accident.
Chinese patent ZL201010531099.X discloses a kind of high-tension winding motor sliding ring structure; Through whole slip ring structure is moved on to base inner, and filter the carbon dust that slip ring produced, improved the degree of protection of slip ring with filter; This device has well solved prior art problems; But need motor be welded repacking again, cost is higher, and operation is complicated.
Chinese patent ZL201020564590.8 discloses a kind of slip ring structure of coiling electric motor high-protection level; Be provided with the slip ring cooler through the slip ring chamber, cooling system is provided with two wind paths, i.e. the outer wind path of wind path and slip ring cooler in the slip ring; Well solved prior art problems; But need configuration corresponding air/water cooler, cooling water and circulation waterway, system complex, cost is higher; The indoor wind path circulation of slip ring simultaneously is for fully closed, and carbon dust is easy to cause creepage short circuit indoor the flying upward of slip ring of sealing everywhere.
Summary of the invention
The utility model is to above-mentioned technical problem, provide a kind of simple in structure, the ventilation cooling effect is good and cost of manufacture is low, is difficult for the good coiling electric motor of creepage short circuit safety with the slip ring cooling structure that ventilates.
The utility model provides following technical scheme for solving the problems of the technologies described above: a kind of coiling electric motor comprises slip ring chamber, slip ring, brush holder and carbon brush, fan, carbon dust filter with the slip ring cooling structure that ventilates; The slip ring chamber is fixedly mounted on the coiling electric motor end cap; Machine shaft stretches into the slip ring chamber, and slip ring sleeve is loaded on the machine shaft, and the slip ring top is equipped with brush holder and carbon brush; It is characterized in that rear end, slip ring chamber cavity is scroll casing shape; It is built-in with fan, and described fan is fixed on the machine shaft end, and the bottom, slip ring chamber at electric motor end cap place is provided with air inlet; The volute body top of slip ring chamber is provided with air outlet along the spiral case tangent line, and the carbon dust filter is installed in the described air outlet.
For further explaining technique scheme, introduce the operation principle of the utility model below in detail: in this device, the spiral case of slip ring chamber and the fan of Qi Nei constitute the spiral case fan; Air inlet, the tangent air outlet of spiral case and spiral case top, the three is the important component part of cooling air duct, when coiling electric motor is worked; The machine shaft high speed rotating, slip ring produces high heat, and the indoor fan of slip ring is opened; Cold air sucks from air inlet, through the deep bead that is arranged at the slip ring below cold wind as much as possible is passed between slip ring, carbon brush and brush holder, heating behind cold air chance slip ring, carbon brush and the brush holder; And sneak into carbon dust on carbon brush and the brush holder; The fan that is mounted in the scroll casing shape cavity of rear end, slip ring chamber sucks, and discharges from air outlet, and the carbon dust filter of the carbon dust in the hot-air in air outlet filters.
As the further improvement of the utility model, the air inlet end of fan is provided with baffle plate, has optimized the air flow wind path through this kind setting, makes that cold air is more efficiently to be passed between slip ring, carbon brush and brush holder, improves cooling effectiveness.
Further improvement as the utility model; On the slip ring chamber internal chamber wall at air inlet place deep bead is installed; Described deep bead is round the front end of slip ring and distribute thereunder, and chamber is directly sucked volute body by fan and discharged by air outlet the cold air that prevents to get into from air inlet through this kind setting from the slip ring below, and the cold air that air inlet is sucked is more efficiently from the slip ring internal flow; Optimize wind path, improve cooling effectiveness.
As the further improvement of the utility model, the air outlet place is provided with shutter, and the air inlet place is provided with shutter, prevents that effectively big dust particle from getting into the slip ring chamber, and the incidence of reduction accident has improved the degree of protection of slip ring chamber.
The utility model forms a counterclockwise cooling channel loop through the spiral case fan structure being set in the slip ring chamber and making air inlet and air outlet is provided with in the same way, makes to the utlity model has following advantage: 1, simple and reliable for structure, there is not additional cooling device, and cost is low.2, can improve the ventilation cooling effect of slip ring and brush holder support, guarantee the reliability service of coiling electric motor, good running environment can prolong the useful life of carbon brush and slip ring simultaneously, shortens the replacing frequency of carbon brush, has reduced maintenance cost.3, this cooling structure, wind path is smooth, and carbon dust is discharged to the slip ring outside through filter, can not cause carbon dust to assemble, and forms short circuit phenomenon.
