Abstract
The invention discloses a wind path structure of an inner slip ring winding motor. The wind path structure comprises a cylinder, a wind shield plate, an inner wall and a double-faced fan. One end of the double-faced fan is a slip ring cooling fan facing towards a slip ring chamber, and the other end of the double-faced fan is a motor winding cooling fan facing towards a motor body. The slip ring cooling fan is separated from the motor winding cooling fan through the inner wall, the end face of the slip ring cooling fan is connected with one end face of the wind shield plate, and the outer circumference of the other end face of the wind shield plate is connected with the cylinder. The double-faced fan achieves motor slip ring cooling and motor body cooling at the same time, two wind paths do not interfere with each other, and bearings are all located on a cold wind area. According to the wind path structure of the inner slip ring winding motor, the structure is simple, the cooling effect is better, the axial space is saved, the bearing distance is shortened, the deflection of the shaft is smaller, the critical speed of revolution of a motor is higher, motor vibration is reduced, and the reliability and safety of the motor are improved.
Description
Technical field
The invention belongs to machine field, be specifically related to slip ring coiling electric motor wind path structure in a kind of interchange.
Background technology
Three-phase winding-type asynchronous motor due to can outer meeting resistance on its rotor, has higher starting torque and less starting current when starting, therefore, in fields such as metallurgy, chemical industry, building materials, machinery, mines, generally adopts this motor to carry out driven equipment.Interior slip ring coiling electric motor is wherein more special a kind of, and the slip ring of this motor, in base inner, is compared with outer slip ring motor, and length is less, more saves installing space, uses at home lessly, but external client comparatively favors.But because slip ring is arranged on electric machine stand inside, increased bearing distance, amount of deflection is increased, critical whirling speed reduces, and make the motor internal anxiety of arranging, carbon dust cleaning inconvenience.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of wind path structure of interior slip ring coiling electric motor is provided, improve the performance of motor each side, increase running reliability of motor and fail safe.
Technical scheme of the present invention is as follows:
A wind path structure for interior slip ring coiling electric motor, comprises cylinder, deep bead, inwall and Double-faced fan; One end of described Double-faced fan is the slip ring cooling fan towards slip ring room, and the other end is the motor winding cooling fan towards motor main body; In the middle of slip ring cooling fan and motor winding cooling fan, with inwall, separate; The end face of described slip ring cooling fan connects the end face of deep bead; On the other end excircle of described deep bead, connect cylinder.
Useful technique effect of the present invention is:
Cooling and the motor main body of motor sliding ring of the present invention is cooling shares a Double-faced fan, and two wind paths are non-interference, and bearing is all in cold wind district.Of the present invention wind path structure is simple, and cooling effect is better, has more saved axial space, shortens bearing distance, makes the amount of deflection of axle less, and motor critical speed is higher, has reduced motor oscillating, and has improved the reliability and safety of motor.
Advantage of the present invention will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the present invention includes a cylinder 1, deep bead 2, inwall 3 and a Double-faced fan 4.The left end of Double-faced fan 4 is slip ring cooling fan 41, towards slip ring room; Right-hand member is motor winding cooling fan 42, towards motor main body.In the middle of slip ring cooling fan 41 and motor winding cooling fan 42, with inwall 3, separate.The left end of slip ring cooling fan 41 connects deep bead 2, on the left side excircle of deep bead 2, connects cylinder 1.
Wind path has identified clear in Fig. 1 with arrow, inwall 3 and Double-faced fan 4 separate slip ring room and the wind path of motor main body, motor lower portion is equipped with carbon dust filter 5, make carbon dust cannot enter motor main body, effectively prevent that carbon dust is at winding surface sediment, avoid winding overheated or cause creepage distance to reduce because carbon dust covers winding surface, and then electric discharge, make ageing of insulation, winding burns out; Cylinder 1 is concentrated the hot blast of slip ring room with deep bead 2 from the left side of Double-faced fan 4, to throw away to cooler, carry out heat exchange, and this structure makes blast higher, and air quantity is larger, is more conducive to cooling; The cold wind that the right side fan of Double-faced fan 4 throws away rear and cooler by the hot blast of motor main body forms reverse heat-exchange, and heat exchange efficiency is higher, is more conducive to reduce electric machine temperature rise.Wind path structure of the present invention makes motor bearings at both ends all in cold wind district, is beneficial to reduction bearing temperature, has avoided conventional interior slip ring motor one end bearing bearing temperature when hot blast district high.Wind path structure of the present invention makes motor axial space compacter, has shortened bearing distance, and amount of deflection is little, and critical whirling speed is high, makes motor operation more reliable, safer.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
