Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates generally to a motor, and more particularly to a housing of a motor, which is applied to both of the vertical motor and the horizontal motor.  
         [0003]     2. Description of the Related Art  
         [0004]     Conventional motors are classified into an IEC specification that is widely used in European and Japan and a NAMA specification that is widely used in U.S.A., and also are classified into vertical motors and horizontal motors depended on the installation posture of the motor.  
         [0005]     The conventional vertical motor has a barrel and a front lid mounted at an end of the barrel, wherein the front lid has a greater diameter than the barrel and has a plurality of holes at a margin, the portion beyond the housing. Bolts are inserted into the holes of the front lid respectively to fasten the motor onto a predetermined plane. The conventional horizontal motor has a barrel and a stand mounted on an outer surface of the barrel. The stand is fastened onto a predetermined plane whereby the motor is fixed in a horizontal condition. The horizontal motor still has a front lid and a rear lid, which are respectively mounted at opposite ends of the barrel and have a same diameter. Generally, the front lid used in the vertical motor is greater in diameter then the front lid used in the horizontal motor.  
         [0006]     Any series motor has both of the vertical type and the horizontal type, so that the manufacturer has to prepare two kinds of front lids for the vertical and horizontal motors. It has a higher cost to store the different types of motors. There was a motor, which is applied to both of the vertical type and the horizontal type, in Europe. Such motor has a greater front lid like the vertical motor and a detachable stand mounted on a barrel thereof. The motor can be fastened through the stand like the horizontal motor. Alternatively, the motor can be fastened through the front lid when the stand is detached from the motor. Such motor has the greater front lid and it looks strange to consumers, so that the motor is not popular in the market. People still buy the vertical or horizontal motors rather than aforesaid motor.  
         [0007]     In addition, if a motor can be fastened as both of the vertical and horizontal motor, the stand must be higher so as to elevate the front lid off the ground while the motor is fastened through the stand. Such motor with the higher stand does not meet the requirement of the IEC specification.  
       SUMMARY OF THE INVENTION  
       [0008]     The primary objective of the present invention is to provide a housing of a motor, which is applied to both of the vertical and horizontal motor.  
         [0009]     Another objective of the present invention is to provide a housing of a motor, which has no aforesaid drawbacks.  
         [0010]     According to the objectives of the present invention, a housing of a motor comprises a barrel having a plurality of fins on an outer surface thereof and a plurality of stands on a bottom of the outer surface for mounting the motor onto a predetermined plane horizontally. A rear lid is mounted at a rear end of the barrel and has an axle hole at a center thereof. A front lid is mounted at a front end of the barrel and has an axle hole at a center thereof. A front disk that has a diameter greater than that of the barrel is detachably fastened to the front lid through at least a fastener. The front disk is provided with a plurality of fastening holes for mounting the motor onto a predetermined plane vertically.

A stator and a rotor are received in the barrel  11 . The stator and the rotor are conventional devices, so that we would not describe their detail here.  
         [0023]     The rear lid  21  is mounted at the rear end of the barrel  11  having an axle hole  22  at a center thereof.  
         [0024]     The front lid  31  is mounted at the front end of the barrel  11  having an axle hole  32  at a center thereof. A spindle (not shown) is inserted into the axle holes  22  and  32  of the rear lid  21  and the front lid  31 .  
         [0025]     The characters of the present invention are described hereunder:  
         [0026]     The barrel  11  has a plurality of elongated ribs  16  on the outer surface and between the fins  12 . Each of the ribs  16  respectively has a thread hole  17  at a front end thereof.  
         [0027]     The front lid  31  has a hill portion  34  and an annular stop plane  35  around the hill portion  34 . The hill portion  34  has a diameter smaller than the barrel  11 .

         [0032]     The way of how to mount the motor of the second preferred embodiment in vertical or in horizontal is as same as the motor of the first preferred embodiment, so that we would not describe again.  
         [0033]     As shown in  FIG. 6 , a housing  60  of a motor of the third preferred embodiment is similar to the housing  10  of the first preferred embodiment, except that a front lid  61  has a plurality of flanges  62 . Exterior ends of the flanges  62  and a stop plane  64  of the front lid  61  are located at the same plane. A front disk  65  is attached on both of the stop plane  64  and the exterior ends of the flanges  62 . Each of the flanges  62  has a hole  63  aligned to thread holes  671  of ribs  67  respectively and the front disk  65  has holes  66  aligned to the holes  63  of the flanges  62  respectively. Fasteners  68 , which are bolts, are respectively inserted into the holes  66  and  63  of the front disk  65  and front lid  61  and are screwed into the thread holes  671  of ribs  67 . The front disk  65 , therefore, is fastened on the front lid  61 .  
         [0034]     The way of how to mount the motor of the third preferred embodiment in vertical or in horizontal is as same as the motor of the first preferred embodiment, so that we would not describe again.  
         [0035]     As shown in  FIG. 7  and  FIG. 8 , a housing  70  of a motor of the fourth preferred embodiment is similar to the housing  10  of the first preferred embodiment, except that an end of a front lid  75  is a flat plane and an end of a front disk  77 , on which the front lid  75  is attached, is a flat plane too.  
         [0036]     The way of how to mount the motor of the fourth preferred embodiment in vertical or in horizontal is as same as the motor of the first preferred embodiment, so that we would not describe again.  
         [0037]     As shown in  FIG. 9  and  FIG. 10 , a housing  80  of a motor of the fifth preferred embodiment is similar to the housing  10  of the first preferred embodiment, except that a front lid  85  has a recess  86  on an exterior end thereof and a front disk  87  has a plunge  88  to be engaged with the recess  86  of the front lid  85 .  
         [0038]     In addition, fasteners  89 , which are bolts in the present preferred embodiment, are inserted into holes  871  of the front disk  87  and screwed into thread holes  851  of the front lid  85 .  
         [0039]     The way of how to mount the motor of the fifth preferred embodiment in vertical or in horizontal is as same as the motor of the first preferred embodiment, so that we would not describe again.  
         [0040]     The advantages of the present invention are:  
         [0041]     1. The motor with the housing of the present invention can be mounted both in vertical type and in horizontal type. The front disk is applied to mount the motor in vertical type and it is detached while the motor is mounted via the stand in horizontal type.  
         [0042]     2. Because the present invention provides the front disk detachable, it does not have to provide a higher stand as the conventional one do. The motor with the housing of the present invention can be mounted in horizontal type while the front disk is detached. It overcomes the drawback of the conventional one as described in the background of the present specification.  
         [0043]     3. The housing of the present invention only has one specification that meets both of the vertical motor and the horizontal motor. In other words, the motor with the front disk is the vertical motor and the motor without the front disk is the horizontal motor. It simplifies the procedure of manufacture and reduces the cost of storage.  
         [0044]     The main scope of the present invention is that the detachable front disk is provided to make the motor can be the vertical motor or the horizontal motor. The way of how to fasten the front disk to the front lid is not restricted in the preferred embodiments. Any equivalent structure or device is still within the scope of the present invention.
