Abstract
The utility model belongs to an explosion-proof type electricity product in an exploding dangerous place, which is a compact structure type high-pressure explosion-proof type motor. The utility model is composed of a rotor, an outer cover, a bearing, an explosion-proof surface, a bearing sleeve, an end cover, a connection box, a suspension ring, a stator, a machine seat, an inner wind shield, an outer wind shield, an end shield, radiation fins and a connecting seat, wherein the bearing is used for supporting the rotor; the bearing sleeve and the end cover are connected with the machine seat by screw bolts; the stator, the connection box and the suspension ring are respectively fixed on the machine seat; the inner wind shield is fixed on the rotor; the parallel radiation fins orthogonally distributed are arranged at the external side of the machine seat. The utility model has the advantages of simple and compact structure, small volume, light weight, beautiful appearance, low noise, small vibration and good radiation. When a rotation shaft is heated to inflate, the extending end of a motor shaft can not generate displacement. At the same center, the output power of the utility model is higher than that of a traditional explosion-proof type high-pressure motor.
Description
Technical field: the utility model belongs to the explosion-proof type electric product of using in the explosion hazard area, is a kind of compact conformation formula high voltage flameproof motor.
Background technology: existing high voltage flameproof motor generally adopts the steel plate support, and its structure has two kinds: a kind of is that steel plate is rolled up postwelding, at the ventilation duct of its outer surface welding fin and connection support two ends ventilation hole.Another kind is to adopt the expand tube structure, promptly is provided with ventilation duct between shell and stator, and ventilation duct is fixed on the end plate at support two ends by the expand tube mode.These two kinds of structures one are that heat radiation is bad; The 2nd, when the rotating shaft expanded by heating, can cause spindle nose to produce displacement to motor shaft extension end, can cause damage to shaft coupling or load.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of close-coupled high voltage flameproof motor simple in structure, reliable is provided, and has solved heat radiation problem such as bad.The purpose of this utility model be achieved in that the close-coupled high voltage flameproof motor by: rotor, enclosing cover, bearing, explosion suppresion surface, bearing holder (housing, cover), end cap, terminal box, suspension ring, stator, support, interior fan housing, outer fan housing, end shield, fin, Connection Block are formed.The bearing supporting rotor, bearing holder (housing, cover), end cap links together by bolt and support, bearing holder (housing, cover) and rotor form explosion suppresion surface, bearing holder (housing, cover) and end cap constitute explosion suppresion surface, end cap and support constitute explosion suppresion surface, stator is fixed in the support, adopt interference fit, outer fan housing is connected and fixed by key and rotor, and end shield is by being bolted on the support, the shaft extension end bearing is placed in the bearing holder (housing, cover), enclosing cover is fixed on the bearing holder (housing, cover), and terminal box is fixed on the support with bolt or by Connection Block, and suspension ring are fixed on the support, interior fan housing is fixed on the rotor, and base outer is provided with the parallel fin of omnidirectional distribution.This product structure is simple, compact, volume is little, in light weight, good looking appearance, noise is low, vibration is little, good heat dissipation.During the rotating shaft expanded by heating, motor shaft extension end can not produce displacement, and its power output of same center is higher than traditional flameproof high-voltage motor.
