Abstract
The utility model provides a motor of a heading machine, belonging to the technical field of machinery and being used for solving the problem of poor sealing effect of the traditional motor of the heading machine. The motor of the heading machine comprises an enclosure in which a stator, a rotor, a coil winding and a motor shaft are arranged, wherein the front end of the enclosure is fixedly connected with a front end cover, the inner end surface of the rear rend of the front end cover is fixedly connected with a front outer cover, and the end surface where the front outer cover is in contact with the front end cover is provided with a sealing groove in which a sealing strip is arranged. The motor of the heading machine has the advantages of simple structure and good sealing effect.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of motor, particularly a kind of motor that is applicable in the development machine.
Background technology
The development machine motor is in long-term use procedure, Market reaction often has bearing failure, insulation resistance is low and the phenomenon of motor damage, these all are that the motor seal weak effect causes, so that the user stops production and repairs and change motor, cause huge economic loss to the user, this is the ubiquitous problem of this type of motor.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of development machine motor of simple in structure, good sealing effect.
The purpose of this utility model can realize by following technical proposal: a kind of development machine motor, comprise casing, stator, rotor, coil windings and motor shaft are installed in the described casing, described casing front end is fixed with front end housing, it is characterized in that, be fixed with front enclosing cover on the inner face of described front end housing rear end, described front enclosing cover offers seal groove and sealing strip is installed in seal groove at the end face that contacts with front end housing.
Compared with prior art, this development machine motor is by increasing seal groove at front enclosing cover, between front enclosing cover and front end housing, increase sealing strip, thereby the sealing property before strengthening between enclosing cover and the front end housing, the slit of having stopped between current the past enclosing cover and the front end housing is penetrated into motor internal, prevent burn-down of electric motor, good sealing effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram at A place among Fig. 1.
Fig. 3 is the structural representation of front enclosing cover in the utility model.
Among the figure, 1, casing; 2, stator 3, rotor 4, coil windings 5, motor shaft; 6, front end housing; 7, front enclosing cover; 71, seal groove 8, sealing strip.
Embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Such as Fig. 1, Fig. 2 and shown in Figure 3, this development machine motor comprises casing 1, stator 2, rotor 3, coil windings 4 and motor shaft 5 are installed in the casing 1, casing 1 front end is fixed with front end housing 6, enclosing cover 7 before the inner face of front end housing 6 rear ends is fixed with offers seal groove 71 and sealing strip 8 is installed in seal groove 71 at the end face that contacts with front end housing 6 at front enclosing cover 7.
This development machine motor is by increasing seal groove 71 at front enclosing cover 7, between front enclosing cover 7 and front end housing 6, increase sealing strip 8, thereby the sealing property before strengthening between enclosing cover 7 and the front end housing 6, the slit of having stopped between current the past enclosing cover 7 and the front end housing 6 is penetrated into motor internal, prevent burn-down of electric motor, good sealing effect.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.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 spirit of the present utility model or surmount the defined scope of appended claims.
