Abstract
The utility model relates to an explosion-proof motor used in inflammable and explosive environment, comprising a body, a rear end cover and a motor shaft, wherein, the rear end cover and the motor shaft are arranged on the body. The utility model is characterized in that: the rear end cover is provided with a flameproof rear cover through a bolt; the flameproof rear cover respectively forms a flameproof surface A and a flameproof surface B with the motor shaft and the rear end cover; the motor shaft is provided with a brake; the gap between the detent and the flameproof rear cover is provided with a power lost brake coil and a brake magnet; and the brake is provided with brake friction plates. The explosion-proof motor not only can be used in the inflammable and explosive environment, but also has the characteristics of simple structure and convenient installation; in the environment of explosion and combustion, the motor can be stopped by the brake swiftly, which improves the safe operation reliability of the motor.
Description
Technical field:
The utility model relates to a kind of motor, particularly relates to a kind of fire-proof motor that applies to use under the inflammable and explosive environment.
Background technology:
The fire-proof motor of domestic production now all is to adopt bearing pedestal that bearing is installed, and pushes down bearing inner race bearing fixing at inside cap again.This structure is waste material both, and also trouble of assembling, because inside cap is mounted in motor internal, screw is difficult on the inside cap during assembling aligns with the bearing pedestal screw, often will finish this work with the long period when assembling.Simultaneously, under situation that cannot see the adjustment position, be difficult to the inside cap leveling is so just often made the contact of inside cap endoporus, destroy the normal operation of motor, owing to frictional force motor is burnt sometimes with three bolts that connect inner end cap.
Summary of the invention:
The purpose of this utility model is exactly to be to avoid above-mentioned the deficiencies in the prior art part and fire-proof motor that a kind of new structure is provided, and it can satisfy under the inflammable and explosive environment and uses, and has characteristics simple in structure, easy for installation simultaneously again.
The purpose of this utility model is achieved in that a kind of new type explosion proof motor comprises body, rear end cap, motor shaft, rear end cap and motor shaft are installed on the described body, it is characterized in that: on described rear end cap, the flame proof bonnet is installed by bolt, described flame proof bonnet forms explosion suppresion surface A and B respectively and between described motor shaft and the rear end cap, on described motor shaft, brake is installed, the electricity loss brake coil is installed in space between described brake and flame proof bonnet and brake is inhaled iron, on described brake brake bush is installed.
The utility model compared with prior art has following advantage:
1. owing to covering the flame proof bonnet is installed, fundamentally improves explosion-proof performance, have characteristics simple in structure, easy for installation simultaneously at motor rear end.
2. owing between flame proof bonnet and rear end cap, brake apparatus is installed, make motor under the environment that blast or burning occur, motor is braked rapidly, improve the safe operation reliability of motor by brake.
Description of drawings:
Fig. 1 is that structural representation 1. bodies 2. rear end caps 3. bolts 4. explosion insulation shells 5. motor shafts 6. electricity loss brake coils 7. brakes 8. brake bush 9. brakes of a kind of new type explosion proof motor described in the utility model are inhaled iron
Embodiment:
As can be seen from Figure 1, a kind of new type explosion proof motor comprises body 1, rear end cap 2, motor shaft 5, rear end cap 2 and motor shaft 5 are installed on the described body 1, it is characterized in that: on described rear end cap 2, flame proof bonnet 4 is installed by bolt 3, described flame proof bonnet 4 forms explosion suppresion surface A and B respectively and between described motor shaft 5 and the rear end cap 2, on described motor shaft 5, brake 7 is installed, electricity loss brake coil 6 is installed in space between described brake 7 and flame proof bonnet 4 and brake is inhaled iron 9, on described brake 7 brake bush 8 is installed.
In use, when motor and electricity loss brake coil switch power, the electromagnetic attraction that coil produces holds suction iron, the time brake bush unclamp; In case after the emergency deenergization occurring, the electromagnetic force that coil produces disappears, suction iron compresses the friction plate on the brake under the effect of spring, cover the generation braking moment at motor rear end.
