Abstract
The utility model relates to an explosion-proof motor, which comprises a front end cover, a machine casing, a stator and a rotor. The front end cover is arranged on the machine casing coaxially, the stator and the rotor are coaxially arranged in the machine casing, a rotor shaft is arranged on the front end cover, and joint faces between the front end cover and the machine casing are spigot joint faces. The motor integrates a rear end cover with the machine casing, middle links are reduced, and mechanical processing and assembling are both easy. Simultaneously, the quantity of the explosion-proof joint faces of the motor is small, gaps among the explosion-proof joint faces are different according to the length of the joint faces, furthermore the explosion-proof joint faces are connected in spigot mode so that the higher the explosion-proof level is and the smaller the gaps are, coaxiality degree of spigots and a bearing chamber is guaranteed, and an explosive-proof effect is improved.
Description
Technical field
The utility model belongs to electric motors, relates in particular to a kind of flameproof motor.
Background technology
At present, existing JD series plain edition motor, by and inner stator rotor constitute, front end housing, rear end cap are homoaxial screw with support and are connected, dismounting is comparatively difficult; And, be the end face connection because the mutual assembling of three cooperates, so the flame proof effect is relatively poor.In addition, the motor of this kind structure not only dismounting is comparatively difficult, and casting processing is time-consuming, and only is applicable to a kind of power motor.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of flameproof motor is provided, and this motor drive mechanism is simple in structure, design science, dismounting is simple, flame proof is effective.
The utility model is realized through following technical scheme:
A kind of flameproof motor; Comprise front end housing, casing and stator rotor, it is characterized in that: front end housing is coaxial to be installed on the casing, coaxial installation stator rotor in casing; Armature spindle is installed on front end housing, and till the composition surface between front end housing and the support shape of the mouth as one speaks composition surface.
And the structure on the seam type composition surface between said front end housing and the support is: with the contacted front end housing of casing on be shaped on a boss, axial plane contacts in the outer axial face of this boss and the casing of overcoat, the axial plane that forms seam connects.
The advantage and the beneficial effect of the utility model are:
1, this motor is integrated rear end cap and casing, has reduced intermediate link, and machining and assembling are all easy.
2, the flameproof joint of this motor is less, and its gap length is different by composition surface length, and flameproof joint is that seam connects, and the flame proof grade is high more, and the gap is more little, has guaranteed the axiality of seam and bearing chamber, has strengthened the flame proof effect.
3, simple, the design science of this electric motor structure can realize that several kinds of different capacity motors are placed in the casing, and its stator length is different, and all the other are measure-alike, use more convenient.
Description of drawings
Fig. 1 is the utility model structural profile sketch map.
Fig. 2 is the stereochemical structure generalized section of the utility model.
Embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection range of the utility model with this.
A kind of flameproof motor is made up of front end housing 4, casing 1 and stator rotor 2, and front end housing is coaxial to be installed on the casing, and coaxial installation stator rotor in casing is installed armature spindle 5 on front end housing.
The innovative point of the utility model is:
1, rear end cap and support integral production have reduced the assembling work step, have reduced flameproof joint.
2, shape of the mouth as one speaks composition surface till the composition surface between front end housing and the support, promptly with the contacted front end housing of casing on be shaped on a boss 3, axial plane contacts in the outer axial face of this boss and the casing of overcoat, the axial plane that forms seam connects, and has improved the flame proof grade thus.
The utility model is not described in detail part and is prior art.
Claims (2)
1. flameproof motor; Comprise front end housing, casing and stator rotor, it is characterized in that: front end housing is coaxial to be installed on the casing, coaxial installation stator rotor in casing; Armature spindle is installed on front end housing, and till the composition surface between front end housing and the support shape of the mouth as one speaks composition surface.
2. flameproof motor according to claim 1; It is characterized in that: the structure on the seam type composition surface between said front end housing and the support is: with the contacted front end housing of casing on be shaped on a boss; The outer axial face of this boss contacts with the interior axial plane of the casing of overcoat, and the axial plane that forms seam connects.
