Abstract
The utility model relates to an explosion-proof electric machine housing, and belongs to the field of electric machines. The electric machine comprises a square tubby housing body and an end cover body. Radiating reinforcing ribs are disposed on the housing body, fastening buckles are disposed on an outer side of an opening end face of the housing body, and a first explosive-proof belt is disposed in an inner side. Both sides of the end cover body are provided with radiating reinforcing ribs, a second explosive-proof belt which cooperates with the first explosive-proof belt is disposed on an inner side of an opening end face of the end cover body, and fastening buckles are disposed on an outer side of an opening end face of the end cover body. The radiating reinforcing ribs are casted integrally with the housing body and the end cover body. Four groups of the fastening buckles are arranged in an eight-hole manner. The electric machine housing has good explosive-proof stability, and is simple in manufacturing process. The electric machine housing is not easy to deform when explosion occurs, and has high explosion-proof coefficient.
Description
Technical field
The utility model relates to a kind of fire-proof motor shell, belongs to machine field.
Background technology
Flameproof motor is a kind of of fire-proof motor, its shell can sustain by any faying face of shell or structure interval be penetrated into enclosure flammable mixtures internal explosion and do not damage, and can not cause lighting of the outside explosive atmosphere that forms by one or more imflammable gas or steam.At present, fire-proof motor housing end plug complex manufacturing technology on the market, flame proof stability is bad, particularly produces spark or explosion time at motor internal, electric machine casing and end cap may deform and cause explosion suppresion surface to lose efficacy or the housing end plug crackle, have great potential safety hazard.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of fire-proof motor shell of flame proof good stability is provided, and manufacturing process is simple, is difficult for deforming explosion-proof coefficient height at the generation explosion time.
Fire-proof motor shell described in the utility model is characterized in that: the enclosure body of the side's of comprising tubbiness, establish the heat radiation reinforcement on the enclosure body, and the uncovered end face of the enclosure body outside is established and is connected fastening lug, and first flame proof belt is established in the inboard; Comprise the end cap body, end cap body tow sides are all established the heat radiation reinforcement, second flame proof belt is established in the uncovered end face of end cap body inboard, second flame proof belt matches with first flame proof belt, the uncovered end face of the end cap body outside is established and is connected fastening lug, described heat radiation reinforcement and enclosure body, the casting integrated moulding of end cap body, the fastening lug of described connection are four groups of octal formulas.
Operation principle and process:
With bolt housing is closely linked together with the fastening lug that is connected on the end cap, four groups of octal formulas connect fastening lug and connect fastening lug than four holes and have higher bonding strength, prevent that the stability of being out of shape is higher, particularly motor internal generation explosion time can not cause the variation of explosion suppresion surface deformation gap to cause flame proof to lose efficacy.The heat radiation reinforcement promptly satisfies radiating effect, plays the effect of reinforcement again, and makes things convenient for casting process, makes body machined surface and body interior significantly reduce the generation of defective, reduces internal stress, increases mechanical performance, makes the fire-proof motor performance more stable.
Described enclosure body front diagonally opposing corner direct casting is connected with two suspension ring.
Described enclosure body and end cap body adopt GC275 meehanite metal material to cast, its all machined surface wall thickness and boring back residual wall thickness 〉=7mm; The surface is coated with one deck epoxy zinc rich primer earlier, and film thickness 40 μ m are coated with one deck epoxy intermediate coat 50 μ m again, are coated with one deck epoxy finish 40 μ m after final assembly is finished.
The described first flame proof belt width is 27.5mm～32.5mm, and the second corresponding flame proof belt is than the short 1mm of housing; The preceding 10mm of first flame proof belt and the second flame proof belt length of fit is a positioning section, and remaining intersegmental crack is 0.1mm, and the explosion suppresion surface roughness is Ra3.2～1.6.
The beneficial effect that the utility model is compared with prior art had is:
1, being connected of fire-proof motor housing of the present utility model and end cap adopts seam to locate four groups of octal bolts connections, has higher bonding strength, prevent that the stability of being out of shape is higher that particularly motor internal generation explosion time can not cause the variation of explosion suppresion surface deformation gap to cause flame proof to lose efficacy than the connection of four holes.
2, the heat radiation reinforcement of fire-proof motor housing of the present utility model, end cap promptly satisfies radiating effect, play the effect of reinforcement again, and make things convenient for casting process, make body machined surface and body interior significantly reduce the generation of defective, reduce internal stress, increase mechanical performance, make the fire-proof motor performance more stable.
