Abstract
A fan cover of a motor fan comprises a welded tubular end cover and a base board arranged at the bottom of the end cover. One end of the end cover is welded to a conical baffle board and a ring-shaped steel sheet, and a retaining ring and a screen plate are respectively fixed tightly on the inner side and the outer side of the steel sheet. The fan cover of a motor fan is simple and compact in structure and reasonable in welding structure, and is used for being installed onto a fan outside a motor to reduce air resistance and facilitate air entering. Simultaneously, by means of the taper of the baffle board, cooling air in the end cover is effectively and evenly guided into space among radiating fins of the motor, accordingly air resistance is decreased, effective air volume and air pressure are increased, and temperature rise of the motor is reduced. Besides, the fan cover of the motor fan is simple and practical in structure, welding deformation is small, the outside of the fan cover is smooth, stretch-forming dies are not needed, and cost is saved.
Description
Technical field
The utility model relates to the fan housing of compact middle size motor, relates in particular to the fan housing that is used for high-low pressure compact middle size motor fan.
Background technology
Motor fan housing is installed on the motor external fan, be used for guides wind to, be convenient to effective air intake, and play protection fan and dustproof effect.The windage of conventional high-tension compact middle size motor fan housing is bigger, causes the temperature rise of motor higher; And adopt fiberglass folder steel wire, profile is rough, and cost is bigger; Traditional in addition fan housing steel plate adopts Welding Structure, and the fan housing window is very easily thrown with fan housing mutually because of welding deformation causes fan.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, thereby another kind of motor fan shield is provided, and under the situation that satisfies the electric machine temperature rise requirement, saves cost, and smooth-shaped, not yielding.
The technical solution of the utility model is as follows:
A kind of motor fan shield, comprise the end shield of the tubulose that is welded to each other and the base plate of bottom thereof, one end of described end shield is welded with the steel plate of cone shape baffle plate and ring-type, and back-up ring and web plate are fastened on the inside and outside both sides of described steel plate respectively by bolt, spring washer.
Its further technical scheme is: described end shield welded top has suspension ring.Offer a semicircle orifice on the described end shield.The internal diameter of described baffle plate shrinks gradually, and is tapered, and tapering is 20 °.Described back-up ring material is an anti-flammability fiberglass.
Useful technique effect of the present utility model is:
The utility model can be introduced the cooling air of end shield between the fin of motor effectively and uniformly by a baffle plate that tapering is arranged is set, and reduces windage, has improved effective wind rate and blast, has reduced the temperature rise of motor.The utility model smooth in appearance, welding deformation are little; Simple in structure, compact, reasonable welding structure; Do not need to drop into other equipment, do not need to drop into pull-shaped mould mould, save cost.
Description of drawings
Fig. 1 is that master of the present utility model looks cutaway view.
Fig. 2 is a left view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1 and Figure 2, the utility model comprises the end shield 1 of the tubulose that is welded to each other and the base plate 8 of bottom thereof, and an end of described end shield 1 is welded with the steel plate 9 of cone shape baffle plate 3 and ring-type, and the internal diameter of baffle plate 3 shrinks from left to right gradually, tapered, tapering is 20 °.Back-up ring 4 and web plate 7 are fastened on the inside and outside both sides of described steel plate 9 respectively by bolt 5, spring washer 6.Back-up ring 4 materials are anti-flammability fiberglass, can alleviate the weight of whole fan housing, and have fire-retardant function.End shield 1 welded top has suspension ring 2.Offer the semicircle orifice 10 of a R14 on the end shield 1, be used for eliminating because the internal stress that welding causes in welding process.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection range of the present utility model.
