Description
The present invention relates to be used for the wheeled mine hoist of friction that drives the electrical motor that promotes steel cable that has of mining engineering, wherein the rotor of electrical motor is connected with the friction wheel that is designed to cylindrical housing, the stator of electrical motor is fixed on the structure that has hollow shaft and it is being supported, be provided with the foundation support seat, electrical motor is positioned at the cylindrical housing of friction wheel, and by the forced ventilation system supplied with cooling air.This class wheeled mine hoist that rubs has been disclosed in for example German patent DE-OS3705567 and Germany technology magazine " 13/14, the 829 page to 832 pages of Gluckauf 125 (1989) issues ".
In the wheeled mine hoist of this known friction, coolant air passes big opening on the friction wheel backplate both sides and but flows around magnetic pole and stator winding and the slit of passing iron core of electric motor.For importing and discharging coolant air, in the both sides of friction wheel special air scoop has been installed, there is a kind of lining that is made of the non-flammable sound deadener that is used to suppress electric moter noise the inside of cover.In addition, between the friction wheel of fixing cover and rotation anti abrasive anti-gas-leak sealing member is arranged, the sealing part is made of the interior labyrinth that has the brush coating that osed top need not to keep in repair.
The wheeled mine hoist of this known friction, importing with the coolant air of deriving friction wheel and in the both sides, friction wheel outside of rotation fixing air scoop being set all needs quite high construction expenditure and sizable space.Anti-gas-leak sealing member between the friction wheel of fixing air scoop and rotation also will very high expense, because interior labyrinth must have bigger diameter, although interior labyrinth simple structure.
It is imperfect that ventilation noise also proves, ventilation noise is to produce like this, coolant air between air scoop and friction wheel inside must be by in the perforate engaging friction wheel backplate, and the friction wheel backplate always is substantially perpendicular to the flow direction of coolant air when friction wheel from rotation.
The object of the present invention is to provide a kind of wheeled mine hoist of friction of the above-mentioned type, this gig has simple and stable structure, do not have fixing air scoop good in the both sides of friction wheel, thereby between friction wheel and air scoop, just do not need the anti-gas-leak sealing member yet.
This purpose can realize by following feature, promptly
-hollow shaft is imported and escape route as the coolant air of electrical motor,
-hollow shaft is provided with cross wall or next door for this reason on the one hand in osed top or leak free friction wheel, be provided with on its circumference towards friction wheel in-to-in coolant air induction opening and air gate on the other hand.
Solution of the present invention has following advantage,
-do not need the insert (Einhausung) of Koepe formula friction wheel,
-do not need the sealing between insert and the friction wheel;
-(owing to having cancelled insert) only required less space;
-have only less ventilation noise, because coolant air a internal cavities by friction wheel.
Because hollow shaft of the present invention not only is used to penetrate the cable of electrical motor by common mode, and, obviously,, must use hollow shaft than large diameter in order to allow enough big cooling air volume pass through as cooling air channels.Consequently, friction wheel is bearing in the bearing that turns round on the hollow shaft because structural condition determines to adopt the bearing of large-size by them.From and brought such advantage, that is, the bearing of such friction wheel has the long life-span, thereby has improved the calmness running of friction wheel.
It is particularly advantageous that the layout of friction wheel hoist of the present invention has been proved to be, and according to this layout, the induction opening of coolant air and air gate are located at the both sides that deviate from mutually of motor stator, and aim at diametrically basically.Reach thus and cause special actv. and ventilate, enable the high loss power of the electrical motor of for example 300kW is drained reliably by the friction wheel in-to-in.
On this meaning, when the hollow shaft in friction wheel is provided with the cross-sectional plane extension of the stator support that constitutes electrical motor, has good effect, this cross-sectional plane extension has the wall section of two relative tilts, is provided with the induction opening and the air gate of coolant air in the wall section of these two relative tilts.
The induction opening of coolant air and air gate along the circumferential direction are arranged on evenly distributedly to help making by friction wheel in-to-in windstream on the wall of hollow shaft and keep optimum distribution.
At last, important also has, and the inside face of hollow shaft is provided with body insulation, and preferably the sound insulation coating causes the self-noise that reduces electrical motor so that reach.
A unique figure half illustrates the wheeled mine hoist of the friction with architectural feature of the present invention with left section drawing, half with lateral plan.
The mine hoist that can find out from accompanying drawing has a friction wheel 1, and it has four groovings 3 of even spaced apart setting mutually on its cylindrical housing 2.
One of friction wheel backplate 4 partly is an annular solid 7 that is provided with around friction wheel longitudinal axis 6-6 with one heart, this annular solid 7 surrounds an antifriction-bearing box 8, this antifriction-bearing box is supported on again on the periphery of hollow shaft 9, the two ends of hollow shaft 9 are installed in two supporting bases 10, and supporting base 10 is supported on again on the basis 11.
The coolant air of electrical motor 15 for example enters the passage section 18 of hollow shaft 9 left parts 12 by the cooling air channels 19 on the left side, run into next door 21 and turn to induction opening 22 in middle part 13, shown in arrow among the figure.Coolant air passes the cavity 5 in the induction opening 22 engaging frictions wheel 1 and acts on the stator 14 and rotor 16 of electrical motor 15, arrives air gate 23 then; Run into the passage section 18 of next door 21 diverted flow from the coolant air that air gate 23 comes out, flow into the cooling air channels 19 on the right from there to the right part 12 of hollow shaft 9.
Be proved to be advantageously, the inside face of hollow shaft 9 all is provided with body insulation, a kind of sound insulation coating preferably, and limit the inside face of the friction wheel 1 of cavity 5, just the inside face of cylindrical housing 2 and friction wheel backplate 4 also is provided with such body insulation, causes the self-noise that reduces electrical motor thereby reach.
Antifriction-bearing box 8 at the friction wheel on the hollow shaft 91 can be enclosed between two sealing members 24, sealing member 24 abuts on the end 12 of hollow shaft 9 on the one hand, reclining the on the other hand end face of annular solid 7, friction wheel 1 is installed on the antifriction-bearing box 8 by this annular element.So just stoped air from the cavity 5 of friction wheel 1, to spill quite simply.
Owing to hollow shaft 9 is not only the connecting cable that is used to import electrical motor as the access way with the coolant air of friction wheel 1 all-in-one-piece electrical motor, so its passage section 18 cannot be lower than a specified minimum value.For this reason, hollow shaft also has corresponding bigger external diameter at two place, end 12.
Because hollow shaft 9 also is used as the fixed support of the antifriction-bearing box 8 of friction wheel 1, so antifriction-bearing box 8 determines to select bigger size for use owing to structural condition.This has brought special advantage, and the antifriction-bearing box of selecting for use like this 8 has the long life-span with respect to the antifriction-bearing box of conventional specification.
What still will address at last is, in order to reduce the deadweight of friction wheel 1, friction wheel backplate 4 can be offered a plurality of openings 25 along its circumferencial direction, these openings 25 close by the very thin cover plate 26 of wall thickness again, thereby will close or seal up as the cavity 5 of the friction wheel 1 of cooling air channels, thereby avoided air bleed.
