Abstract
The utility model provides an explosion-proof type three-phase asynchronous motor used for a fan, which belongs to the field of mechanical technology. With the adoption of the explosion-proof type three-phase asynchronous motor used for the fan, the problem that a motor is difficult to be installed or a power line is inconvenient to be connected as the existing motor junction box is installed near the front end of a motor body to form 90 degrees with a motor shaft is solved. The explosion-proof type three-phase asynchronous motor used for the fan comprises a motor base, a stator, a rotor, a coil and the motor shaft are installed in the motor base, the front end of the motor base is fixedly connected with a front end cover, a junction box is installed just at the rear end of the motor base, and the junction box is in a straight line with the motor shaft. The explosion-proof type three-phase asynchronous motor used for the fan has a simple structure and is convenient to install and use.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of motor, and particularly a kind of blower fan is used the flame-proof type threephase asynchronous.
Background technology
The terminal box of prior motor is mounted in the forward end of motor fuselage and becomes 90 degree with motor shaft, because the special gas-distributing fan usefulness of this motor, so the bad installation of motor or power line are inconvenient to draw and are connect under many circumstances, uses and keeps in repair and bring certain trouble to the user.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of blower fan simple in structure, easy to install and has used the flame-proof type threephase asynchronous.
The purpose of the utility model can realize through following technical proposal: a kind of blower fan is used the flame-proof type threephase asynchronous; Comprise support; Stator, rotor, coil and motor shaft are installed in the described support; Described support front end is fixed with front end housing, it is characterized in that, it is in alignment that the positive rear end of described support is equipped with terminal box and described terminal box and motor shaft.
Above-mentioned blower fan with the flame-proof type threephase asynchronous in, sealing is fixed with steel ring sheath oil sealing between described front end housing and the motor shaft.
Compared with prior art; This blower fan is with the positive rear end of flame-proof type threephase asynchronous through terminal box being installed in support and in alignment with motor shaft; All more convenient when motor is installed, uses and keeped in repair like this; Realize oil sealing through steel ring sheath oil sealing between motor shaft and the front end housing simultaneously, so not only improved the explosion insulation performance of motor, but also improved the useful life of oil sealing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, support; 2, stator; 3, rotor; 4, coil; 5, motor shaft; 6, terminal box; 7, front end housing; 8, steel ring sheath oil sealing.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; This blower fan comprises support 1 with the flame-proof type threephase asynchronous; Stator 2, rotor 3, coil 4 and motor shaft 5 are installed in support 1; Be fixed with between front end housing 7 and front end housing 7 and the motor shaft 5 sealing at support 1 front end and be fixed with steel ring sheath oil sealing 8, adopt steel ring sheath oil sealing 8 not only to improve the explosion insulation performance of motor, but also improved the useful life of oil sealing.It is in alignment in support 1 positive rear end terminal box 6 and terminal box 6 and motor shaft 5 to be installed, all more convenient when motor is installed, uses and keeped in repair like this.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
