Abstract
The utility model discloses a brushless integrative back lid of fan blade that turns outward, including the lid, the lid is loop configuration, and central authorities set up the shaft hole, and the lid outside is equipped with the round blade, and the blade outside is the outer loop, and the mounting hole of having arranged on the outer loop, the fin of having arranged in the outer loop outside. The utility model has the advantages of reasonable design ingenious, with blade and lid integrated into one piece, the main shaft passes the shaft hole during installation, and the lid passes through the mounting hole and connects the shell, and shell pivoted in-process, blade drive air flow realizes the forced air cooling, and fin and outer loop contained angle department can bond balanced clay as required, guarantee stability of operation, reduce the unbalance amount that the operation produced, balanced clay also is difficult for droing, simple to operate, cost reduction.
Description
Technical Field
The utility model relates to a brushless integrative back lid of fan blade that turns outward.
Background
The back lid of brushless external rotation motor is in the installation, wear the cover in the pivot through fixing bearing, and be connected with the casing, the motor produces the heat at the moving in-process and needs dispel the heat, consequently can install a fan additional at the rear of back lid, in-process at pivot pivoted drives the fan and rotates, dispel the heat, the fan can produce the vibration when rotating on the flywheel, consequently need house dress counter weight buffering because the produced vibration of inertial rotation, the installation is inconvenient, and the counter weight is easy because rotate and the pine takes off.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a brushless integrative back lid of fan blade of turning outward for solve above-mentioned problem.
To achieve the purpose, the utility model adopts the structure that: the integrated rear cover of the brushless outward-turning fan blade comprises a cover body, wherein the cover body is of an annular structure, a shaft hole is formed in the center of the cover body, the blades are uniformly distributed around the cover body, the outer ring is arranged on the outer side of each blade, mounting holes are uniformly distributed in the surface of the outer ring, raised radiating fins are distributed on the outer side of the outer ring, and the height of each radiating fin is higher than that of the outer ring.
The mounting hole is recessed inwards to form a step.
And the included angle between the radiating fin and the outer ring is provided with balance daub.
The beneficial effects are as follows: the utility model has the advantages of reasonable design ingenious, with blade and lid integrated into one piece, the main shaft passes the shaft hole during installation, and the lid passes through the mounting hole and connects the shell, and shell pivoted in-process, blade drive air flow realizes the forced air cooling, and fin and outer loop contained angle department can bond balanced clay as required, guarantee stability of operation, reduce the unbalance amount that the operation produced, balanced clay also is difficult for droing, simple to operate, cost reduction.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a perspective view of the present invention;
FIG. 2 is a front view of the structure of the present invention;
