Description
Technical field
The utility model relates to a kind of mining industry equipment, and especially relating to one, can to realize noise low, the tunnel dedusting fan motor that coefficient of safety is high.
Background technology
Dedusting fan is applied to underground coal mine, Yan Kai lane and shotcrete scope of operation pulp shooting machine, the product dirt setting that the dust such as getting working face are relatively concentrated.Dust laden air purified on the spot and partly can eliminate the poisonous and harmful composition in gas, effectively making operating environment meet industrial hygiene standard protection workman and encroach on from toxic dust, also there is a large amount of combustible dust in dust simultaneously, very easily set off an explosion.Dedusting fan generally coordinates development machine to use, but existing dedusting fan motor exists noise greatly, and the problem that coefficient of safety is low, in the face of the problems referred to above, needs to be further improved existing dedusting fan.
Utility model content
In order to overcome above-mentioned technical problem, the utility model provide one can noise low, the tunnel dedusting fan motor that coefficient of safety is high, the technical scheme of employing is as follows:
Tunnel dedusting fan motor, comprise metal chassis, front end housing, rear end cap and division board, front end housing is connected with metal chassis by bolt, an axis hole is provided with in the middle part of front end housing, electric machine main shaft is through axis hole, electric machine main shaft installs cage rotor, it is stator outside cage rotor, stator is fixed on metal chassis inwall, metal chassis rear portion is provided with fan inside and is fixed on electric machine main shaft, between metal chassis rear end and rear end cap, division board is set, division board center is provided with a circular oil sealing chamber, electric machine main shaft enters the chamber division board and rear end cap through oil sealing chamber, be provided with external fan in chamber and be fixed on electric machine main shaft end, damping sheet is provided with between rear end cap and external fan, damping sheet is fixed on inside rear end cap.
Further, metallic gasket is provided with between described bolt and metal chassis.
Further, described metal chassis ground connection.
Further, described rear end cap has ventilation mesh.
Adopt said apparatus, effectively reduce the noise of motor, be connected and internal oil sealing chamber with metal by ground connection simultaneously, realize the safety work of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of tunnel dedusting fan motor.
Wherein 1-electric machine main shaft; 2-front end housing; 3-stator; 4-cage rotor; 5-fan inside; 6-mono-division board; 7-oil sealing chamber; 8-lubricating oil; 9-external fan; 10-damping sheet; 11-rear end cap; 12-metal chassis.
Embodiment
Tunnel dedusting fan motor as shown in Figure 1, comprise metal chassis 12, front end housing 2, rear end cap 11 and division board 6, front end housing 2 is connected with metal chassis 12 by bolt, between be provided with metallic gasket, metal chassis 12 grounding connection, guarantee conducts, avoid producing electric spark, an axis hole is provided with in the middle part of front end housing 2, electric machine main shaft 1 is through axis hole, electric machine main shaft 1 is installed cage rotor 4, it is stator 3 outside cage rotor 4, stator 3 is fixed on metal chassis 12 inwall, metal chassis 12 rear portion is provided with fan inside 5 and is fixed on electric machine main shaft 1, division board 6 is set between metal chassis 12 rear end and rear end cap 11, division board 6 center is provided with a circular oil sealing chamber 7, oil sealing, 7 inside are full of lubricating oil 8, electric machine main shaft 1 enters the chamber division board 6 and rear end cap 11 through oil sealing chamber 7, be provided with external fan 9 in chamber and be fixed on electric machine main shaft 1 end, damping sheet 10 is provided with between rear end cap 11 and external fan 9, damping sheet 10 generally adopts silica gel plate material, vibrational energy can be consumed, damping sheet 10 is fixed on inside rear end cap 11, rear end cap 11 has ventilation mesh, be beneficial to heat radiation.Whole motor electric part is isolated from the outside, and can not produce electric spark, and have employed noise reduction simultaneously and arrange, running noises obviously reduces.
The above, be only embodiment of the present utility model, and those of ordinary skill in the art are in the scope that the utility model discloses, and the change that can expect easily, within the protection range that all should be encompassed in utility model.
