Abstract
The utility model discloses an explosion-proof three-phase asynchronous motor integrated with a speed reducer, which comprises a motor casing, a speed reducer casing and a motor spindle, wherein the speed reducer is arranged on the motor spindle, and the end of the motor casing is connected with the end of the speed reducer casing through a flange end cover. A bearing hole is arranged on the flange end cover, a sealed bearing is arranged between the flange end cover and the motor spindle, and a mechanical seal is arranged between the flange end cover and the motor spindle. The explosion-proof three-phase asynchronous motor is integrated with the speed reducer so that an output shaft of the motor can serves as an input shaft of the speed reducer, and a frequently-used coupler used for connecting is removed. The explosion-proof three-phase asynchronous motor integrated with the speed reducer is a structure provided with footings and a flange (B35), and the flange end cover is not only the end cover of the motor but also one of cavity walls of the speed reducer simultaneously.
Description
Technical field
The utility model relates to the fire-proof motor field, especially relates to a kind of flame-proof type threephase asynchronous.
Background technology
The connecting of reductor and motor in the colliery generally is that motor has an output shaft, and reductor has a power shaft, through shaft coupling these two axles is linked up then.But this connected mode exist volume big, inconvenient problem is installed, and if shaft coupling connect and exist the error of centralization, the accident of reductor and motor seize then takes place easily, influence is produced, even the meeting damage equipment.
The utility model content
The purpose of the utility model is to provide a kind of flame-proof type threephase asynchronous, and motor and reductor is integrated, has cancelled employed shaft coupling in the existing connection, strengthens security performance.
The technical scheme of the utility model is:
With the integrated flame-proof type threephase asynchronous of reductor, comprise motor case, reductor casing and electric machine main shaft, reductor is housed on the electric machine main shaft, said motor case end is connected through the flange end cap with the end of reductor casing; Said flange end covers and is provided with dead eye, between flange end cap and electric machine main shaft, is provided with sealed bearing, is provided with mechanical seal between said flange end cap and the electric machine main shaft.
Between said flange end cap and sealed bearing, radially be provided with the enclosing cover corrugated gasket.
The motor and speed reducer of the utility model integrates, and the output shaft of motor is the power shaft of reductor just, the shaft coupling of the connection that cancellation is commonly used.The utility model is band footing flanged (B35) structure; The flange end cap not only is the end cap of motor; Also be one of chamber wall of reductor simultaneously; The inner chamber of reductor has existed the lubricating oil of oilgear, because the electric machine main shaft shaft extension of motor also in this cavity, must prevent that lubricating oil from getting into motor internal.To this, the oil injection structure of cancellation electric machine main shaft shaft extension end, the shaft extension end bearing changes sealed bearing into, and the bearing outside increases corrugated gasket, to increase pretightning force.Cancellation inner cap, enclosing cover and flange end cap directly casting are in the same place, and the explosion suppresion surface that axle connects part is covered by original being positioned at, and change into to be positioned at flange end and to cover, and axle connects a part fitting machine tool and seals.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises flange end cap 1, corrugated gasket 2, electric machine main shaft 3, mechanical seal 4, sealed bearing 5, reductor body and motor body.
The reductor body comprises reductor casing 6, and motor body comprises motor case 7, and motor case 7 ends are connected with the end of reductor casing 6, and flange end cap 1 is the part of the flameproof enclosure of motor still not, and participates in constituting the velocity-reducing chamber of reductor.Electric machine main shaft 3 one ends stretch in the reductor casing 6, are connected with reductor.Flange end cap 1 is provided with dead eye, between flange end cap 1 and electric machine main shaft 3, is provided with sealed bearing 5, adopts sealed bearing 5 to be owing to cancelled the oil filler point on original front end flange end cap 1, because adopt sealed bearing 5 not need to add in addition the oiling device.
Radially be provided with enclosing cover corrugated gasket 2 between flange end cap 1 and the sealed bearing 5, enclosing cover corrugated gasket 2 can increase the pretightning force of bearing, makes the bearing operation more reliable.Electric machine main shaft 3 is the power output shaft of motor not only, but also is the power shaft of reductor.Be provided with mechanical seal 4 between said flange end cap 1 and the electric machine main shaft 3, mechanical seal 4 mainly is the lubricating oil in the sealed reduction gearbox, prevents that lubricating oil from getting into motor internal.
Claims (2)
1. with the integrated flame-proof type threephase asynchronous of reductor, comprise motor case, reductor casing and electric machine main shaft, reductor is housed on the electric machine main shaft, it is characterized in that: said motor case end is connected through the flange end cap with the end of reductor casing; Said flange end covers and is provided with dead eye, between flange end cap and electric machine main shaft, is provided with sealed bearing, is provided with mechanical seal between said flange end cap and the electric machine main shaft.
2. the said and integrated flame-proof type threephase asynchronous of reductor according to claim 1 is characterized in that: between said flange end cap and sealed bearing, radially be provided with the enclosing cover corrugated gasket.
