Abstract
The utility model relates to an explosion-proof motor which comprises a casing. A stator is disposed inside the casing and a rotor is rotatably arranged inside the stator. A front end cap is arranged on the front portion of the casing. The explosion-proof motor is characterized in that the casing is composed of a cylindrical shell and a rear end cap, a flame-proof chamber is formed among the rear end cap, the cylindrical shell and the front end cap, and the front end and the rear end of a rotor shaft are respectively disposed on the front end cap and the rear end cap through bearings. The explosion-proof motor has a simple and compact structure, enables the processing difficulty to be reduced, enables the processing precision to be improved, and allows the production cost to be lowered.
Description
Technical field
The utility model relates to a kind of blower fan and uses motor, especially relates to a kind of fire-proof motor, is used for the cooling blower of flame-proof converter motor.
Background technology
Along with the deep propelling of energy-saving and emission-reduction, increasing variable-frequency motor is applied to need explosion-proof place, and is also increasing to the demand that is used for explosion-proof cooling blower wherein.In the prior art, be used for the fire-proof motor of explosion-proof cooling blower, its fire-proof motor shell is made up of casing, end cap two parts; The length of casing is long, the structure more complicated, and the die casting of casing is bigger; The die casting machine tonnage that needs is also bigger; Processing is difficulty, and machining accuracy also is difficult to guarantee, has also increased production cost simultaneously.
The utility model content
The applicant has carried out research and improved to above-mentioned problem, and a kind of fire-proof motor is provided, and is simple and compact for structure, reduces the processing technology difficulty, improves machining accuracy, reduces production costs.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of fire-proof motor; Comprise casing, be provided with stator in the said casing, rotor is rotatable to be installed in the said stator; The front end of said casing is provided with front end housing; Said casing is connected and composed by cylindrical shell and rear end cap, and said rear end cap, cylindrical shell and front end housing constitute explosion-proof chamber, and the front and back ends of said armature spindle is respectively through on the said front end housing and rear end cap of Bearing Installation.
The technique effect of the utility model is:
The disclosed a kind of fire-proof motor of the utility model, simple and compact for structure, casing is connected and composed by cylindrical shell and rear end cap, reduces the processing technology difficulty, improves machining accuracy, reduces production costs.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
As shown in Figure 1; The utility model comprises casing 2; Casing 2 is connected and composed by cylindrical shell 201 and rear end cap 202, and cylindrical shell 201 front ends of casing 2 are provided with front end housing 1, and rear end cap 202 and front end housing 1 are pressed on the two ends of cylindrical shell 201 through bolt and nut 5; Constitute explosion-proof chamber between rear end cap 202, cylindrical shell 201 and the front end housing 1, the explosion suppresion surface between rear end cap 202 and the cylindrical shell 201, between cylindrical shell 201 and the front end housing 1 manufactures and designs by national flame proof codes and standards.Be provided with stator 3 in the casing 2, rotor 4 rotatable being installed in the stator 3, the front and back ends of armature spindle 401 is respectively through on the front end housing 1 and rear end cap 202 of Bearing Installation.
In the utility model, cylindrical shell 201 is processed by steel pipe, and front end housing 1 processes through the die casting parallel operation with rear end cap 202; Front end housing 1 is less with rear end cap 202 volumes; Can use less die casting, the die casting machine tonnage is less, has reduced the processing technology difficulty; Machining accuracy guarantees easily, and reduces manufacturing cost.
