Description
Technical Field
The utility model relates to an end cover especially relates to a micro motor end cover.
Background
At present, heat dissipation holes with the same shape and size are uniformly distributed on the existing motor end cover, and the defect of poor heat dissipation effect exists under the condition that the number of the heat dissipation holes is certain due to the size limitation of the end part of a motor shell; moreover, most of the existing motor end covers are large in size, complex in installation and low in connection strength, and some die-cast motor end covers are large in size and heavy in weight, are difficult to locate in the installation process, and are often used for a long time, so that the motor end covers are prone to axial running. And current motor end cover heat dispersion is not good, and life is short, therefore, an integration motor end cover that heat dispersion is better plays especially important.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above problem and provide a compact structure, the radiating effect is good, intensity is good, light in weight, firm in connection, simple to operate's micro motor end cover.
The technical scheme of the utility model is that: the utility model provides a micro motor end cover, the end cover center be the protruding dead eye of circle form, the end cover center extend all around the connecting plate that has the rectangle form, the connecting plate on be equipped with a plurality of ventilation holes, the end cover center about both ends extend the disk body of a pair of semicircle form respectively, disk body and connecting plate fixed connection, the disk body on be equipped with a plurality of spacing grooves and mounting hole respectively.
Furthermore, the middle of the end cover is in a pagoda shape, the middle of the end cover is composed of a plurality of annular step circles, each step circle is provided with a sealing ring, and the edge of each step circle is provided with a chamfer.
Further, the connecting plate on the symmetry be equipped with a pair of mounting hole, the connecting plate on be equipped with four ventilation holes, four ventilation holes set up on four angles of connecting plate, the ventilation hole set up in the connecting plate inboard, the disk body include the quotation, the quotation positive and negative on set up the inclined plane respectively, the inclined plane respectively with connecting plate fixed connection, the quotation highly be higher than the height of connecting plate.
Furthermore, the inclined plane has a radian, and the thickness of the edge of the connecting plate is twice of that of the connecting plate.
Furthermore, the area of four ventilation holes accounts for half of the area of the connecting plate, and the mounting holes are formed in the connecting plate between the ventilation holes.
The utility model has the advantages that: the structure is compact, the heat dissipation effect is good, the strength is good, the weight is light, the connection is firm, the installation is convenient, and the structure is formed by a plurality of annular step circles and is used for fixedly installing the motor rotating shaft and preventing the motor rotating shaft from axially running; a sealing ring is arranged on each step circle to prevent dust from entering and reduce the generation of static electricity; the area in four ventilation holes accounts for half of the area of the connecting plate, improves the heat dissipation effect, sets up the inclined plane on the quotation positive and negative respectively, the inclined plane respectively with connecting plate fixed connection for the connection of end cover is inseparabler, and the atress is more even, improves joint strength.
