Abstract
The utility model discloses a motor casing and a motor adopting the same. The casing is a cylindrical structure, one end surface of the casing is provided with a bearing chamber for mounting a motor rotor bearing, the bearing chamber is cylindrical, a plurality of air openings for air ducts are arranged on the side wall of the motor casing and are adjacent to the end surface of the motor casing which is provided with the bearing chamber, and the end surface of the motor casing, which is provided with the bearing chamber, is provided with a plurality of reinforcing ribs for reinforcing the end surface of the casing. The motor casing and the corresponding motor can effectively stop breakage to the bearing chamber due to vibration of the motor, thereby prolonging the service life of the motor.
Description
Technical field
The utility model relates to a kind of motor housing, particularly a kind of motor case and the motor of using this casing.
Background technology
One end face of the blower fan drive motors that current daily dust catcher uses links to each other with the end face of draught fan impeller, the armature spindle of motor drives draught fan impeller, the axis of motor case and rotor axis of electric conllinear, the other end of casing is provided with the bearing chamber that the rotor bearing is installed, be provided with the air channel that is connected with draught fan impeller in the motor, the axial side wall of motor case has the air port in several air channels, be used for distinguished and admirable outflow, the air port design is at the end face that is axially arranged with bearing chamber near casing, the distinguished and admirable like this rotor that can pass whole motor, be convenient to the cooling of motor, but this makes also the rigidity of end face of bearing chamber of casing descend; Vibration in use can appear in motor inevitably, the power that this vibration produced finally acts on bearing chamber and bearing chamber is produced the destruction of amplification gradually, finally cause the damage of motor, the destruction that motor oscillating causes is directly quickened in the decline of motor bearings chamber end face rigidity, causes the shortening of electrical machinery life.
The utility model content
The utility model is in order to overcome defective in the above-mentioned prior art, by the reinforcement on the outer end face of a kind of bearing chamber that is located at motor case is provided, suppresses the destruction to bearing chamber that motor oscillating causes, thereby prolongs the useful life of motor.
The utility model provides a kind of motor case, casing is a column construction, one end face of casing is provided with the bearing chamber that the rotor bearing is installed, bearing chamber is cylindrical, the sidewall of motor case offers the air port in two or more air channels, air port and motor case have the end face vicinity of bearing chamber, and casing has the end face of bearing chamber and establishes two or more play booster action to the casing end face reinforcement.
Wherein, the dead in line of the axis of casing and casing bearing chamber.
Wherein, the quantity in air port can be four, is symmetrically distributed with the casing axis; Reinforcement quantity is identical with inlet number, and reinforcement is positioned at the corresponding position in air port.
Wherein, the groove that stamps out for the motor case end of reinforcement.Groove can be the Long Circle of rule; Groove can be the center with the axis of bearing chamber, is radial stretching, extension.The central point in air port is positioned on the radial symmetric face of corresponding recesses.
The utility model also provides a kind of motor, and this motor comprises the motor case that the aforementioned techniques scheme relates to.
Compared with prior art, the utility model plays the fluted body reinforcement of booster action by the bearing chamber end face, the rigidity that makes motor have the end face of bearing chamber is strengthened, and suppresses the destruction to bearing chamber that motor oscillating causes, thereby can effectively prolong the useful life of motor.
Description of drawings
Fig. 1 is the schematic perspective view of the utility model motor case.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-motor case, 2-motor case air port, 3-bearing chamber, 4-fluted body reinforcement.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model is not subjected to the restriction of embodiment.
As shown in Figure 1, motor case 1 of the present utility model is cylindrical, a columniform end face (upper surface among Fig. 1) is provided with bearing chamber 3, the axis conllinear of the axis of bearing chamber 3 and motor case 1, on the sidewall periphery of motor case 1, with casing axis four air ports 2 that are symmetrically distributed, the close motor case 1 in the upper edge in air port 2 has the end face of bearing chamber 3, so that the whole rotor of distinguished and admirable cooling, the turning arc transition in air port.Motor case 1 has the end face of bearing chamber 3 towards the Long Circle groove is arranged, and this groove is strengthened the motor case end faces as reinforcement 4, and fluted body reinforcement 4 is four with motor case air port 2 corresponding quantity.For make fluted body reinforcement 4 the position is set and motor case air port 2 adapts, fluted body reinforcement 4 is plane of symmetry setting with the sagittal plane of casing axis, the central point in motor case air port 2 is positioned on the radial symmetric face of groove.
The utility model is by being provided with the fluted body reinforcement that the bearing chamber end face is played booster action, and the rigidity that makes motor have the end face of bearing chamber is strengthened, and suppresses the destruction to bearing chamber that motor oscillating causes, thereby prolongs the useful life of motor.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
