Abstract
The utility model discloses a fan for motors with a fan hub and leaf blades. A plurality of slots are uniformly distributed on the periphery of the fan hub, the leaf blades are inserted in the slots, and the leaf blades and the fan hub are connected into a whole through the permanent connecting method such as welding joint and adhesive joint. The integral balance performance of the utility model is good, the time of the balance adjustment can be saved, compared with the bolt connecting fan, the weight of the fan is reduced by more than 30%, when the motor is used, the vibration and the noise can be reduced.
Description
The utility model belongs to a kind of motor from colod-application fan.
Motor ventilating fan is made up of fan hub and fan blade usually.An existing class motor ventilating fan forms for the aluminum alloy cast inblock, manufacturing process complexity not only, and reject rate is higher, and will consume a large amount of non-ferrous metal aluminium, and along with the aluminium valency goes up, the fan cost also will increase considerably.For this reason, blade and the fan hub assembly type iron plate fan through Bolt Connection has appearred again.The structure of this iron plate fan is by bolt, nut blade to be pressed on the fan hub support as shown in Figure 1, and the balance pad that the adjustment balance is used also is to lean on bolt.Thereby the weight ratio of whole fan is bigger, addition such as bolt have not only destroyed the attractive in appearance of profile but also have increased the mechanical loss of motor, the most outstanding defective is, blade only compresses by bolt and nut, and do not locate (as add locating piece technology with complexity, also can increase cost), so blade is subjected to displacement easily in processes such as transportation, thereby influence the vibration of motor, even might cause the accident because of nut loosening.
It is a kind of in light weight that the purpose of this utility model is to provide, the stable motor ventilating fan of being convenient to make of balance quality rational in infrastructure.
For achieving the above object, be evenly distributed with several grooves on the fan hub excircle of the present utility model, the blade that forms with mould punching is inserted in the groove, connects with welding or permanent connecting mode such as bonding between fan hub and the blade.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is existing iron plate assembly type fan structure schematic representation.
Fig. 2 is an embodiment's of the utility model a formation schematic representation.
With reference to Fig. 2.The utility model is made up of fan hub (1) and blade (2).Be evenly distributed with the identical groove of several physical dimensions (3) on the excircle of fan hub (1), an end of blade (2) is inserted in the groove (3).Process stiffening rib (4) on the blade (2), not only can increase the intensity of blade (2), and the end of stiffening rib (4) can contact with fan hub (1) outer peripheral surface, determine that with this blade (2) is along the position on the normal direction.Permanent connecting mode between fan hub (1) and the blade (2), welding or bonding way connect.
The utility model is good looking appearance not only, and mechanical loss is little, in light weight, and can guarantee that the fan whole machine balancing is good, has greatly reduced adjustment balance man-hours requirement. Compare with existing bolt assembly type fan, weight can alleviate more than 30%, and vibration and noise all decrease when adopting motor operation of the present utility model.
Claims (4)
1, a kind of motor ventilating fan is made up of wheel hub and blade, it is characterized in that being evenly distributed with several trough (3) on the excircle of wheel hub (1), and an end of blade (2) is inserted in the groove (3), and wheel hub (1) links with permanent connecting mode with blade (2).
2,, it is characterized in that blade (2) has stiffening rib (4) as the said motor ventilating fan of claim 1.
3,, it is characterized in that wheel hub (1) and blade (2) are to link with welding manner as claim 1 or 2 said motor ventilating fans.
4,, it is characterized in that wheel hub (1) and blade (2) are to link with bonding way as claim 1 or 2 said motor ventilating fans.
