Description

A kind of reluctance motor explosion isolation device
Technical field
The utility model relates to the explosion separation structure of mining electric locomotive reluctance motor, specifically uses the flame proof support, the reluctance motor explosion separation structure that flame proof front and rear cover, stator core, stator coil, rotor core, output shaft, position transducer and explosion-proof connection box etc. consist of.
Background technology
There is electric locomotive to use so far from the mine, mostly adopts series DC machine as traction power.But adopt the series DC machine cost higher, adopt reluctance motor more efficient, energy-conservation comparatively speaking, but the requirement of safety and reliability is very high on the mine, in case motor breaks down or even explodes, can cause unpredictable casualties and property loss.
Summary of the invention
For overcoming the above problems, the utility model provides a kind of reluctance motor explosion isolation device.Design of the present utility model is as follows:
A kind of reluctance motor explosion isolation device, by shell, front end housing, rear end cap, stator core, rotor core, rotating shaft, stator coil, explosion-proof connection box, the position transducer front and back bearings forms, stator core is fixed on the shell, stator coil is assembled on the salient pole of stator core, the rotating shaft iron core is fixedly arranged in the rotating shaft, load onto front and back bearings before and after the rotating shaft, one end of rotating shaft is provided with explosion-proof connection box, position transducer is fixedly arranged on the same end of rotating shaft and is positioned at the cavity of explosion-proof connection box, and described explosion-proof connection box is by connection bolt, the flame proof insulating case, cavity and rear end cap form.A kind of reluctance motor explosion isolation device of this structure possesses good explosion-proof effect, and security performance is very high.
Further, better for explosion-proof effect, can be coated with at the faying face of described front end housing, rear end cap and shell standard flame proof oil.
The utility model is energy-conservation, cost is low, explosion-proof effect is good, is fit to marketing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
A kind of reluctance motor explosion isolation device that the present embodiment provides, by shell 1, front end housing 2, rear end cap 3, stator core 4, rotor core 5, rotating shaft 6, stator coil 7, explosion-proof connection box 9, position transducer 10 front and back bearings 13 form, stator core 4 is fixed on the shell 1, stator coil 7 is assembled on the salient pole of stator core 4, rotating shaft iron core 5 is fixedly arranged in the rotating shaft 6, load onto front and back bearings 13 before and after the rotating shaft, one end of rotating shaft is provided with explosion-proof connection box 9, position transducer 10 is fixedly arranged on rotating shaft 6 same ends and is positioned at the cavity 11 of explosion-proof connection box 9, and explosion-proof connection box 9 is by connection bolt 8, flame proof insulating case 9, cavity 11 and rear end cap 3 form.Described front end housing 2, rear end cap 3 are coated with standard flame proof oil with the faying face of shell 1.A kind of reluctance motor explosion isolation device of this structure possesses good explosion-proof effect, and security performance is very high, and cost is also lower simultaneously, is fit to marketing and uses.
But above embodiment is the utility model one better embodiment, but is not the whole of the utility model content, and equivalents and change that all are done in the utility model spirit scope all will be in the utility model protection ranges.
