Abstract
The utility model relates to a fan housing for a middle-low-voltage compact middle-sized motor, and in particular to a motor fan housing, which mainly comprises a suction nozzle and an end shield window, which are installed on an end shield through a tightening bolt and a spring gasket ring, wherein the end shield window is provided with an air inlet hole, the end shield comprises a tubular fan housing ring, a circular right end plate is fixed on the right end of an inner hole of the fan housing ring through a conical supporting ring, and the fan housing ring is provided with a lifting eye anda mounting hole. The fan housing can reduce the air resistance and can b e convenient for the effective air intake. At the same time, the cooling air of the fan housing is effectively and uniformly guided to a heat radiation sheet chamber of the motor, thereby improving the effective air volume and the air pressure and reducing the temperature increase of the motor. The fan housing has simple andpractical structure, small welding deformation and beautiful appearance, and can reduce the investment cost of the mould compared with the ordinary fan house of the motor.
Description
Technical field
The utility model relates to a kind of fan housing that is used for high-low pressure compact middle size motor, especially a kind of motor fan housing.
Background technology
At present, with Siemens 1LA1,1LL1 series and the HXR of ABB AB series is the full fin medium-sized high-pressure electrical machinery of a new generation of representative, no matter be on the appearance and modeling or the runnability aspect, its level all is much higher than homemade YKK series medium-sized high pressure threephase asynchronous.Manufacture and design original, fan housing adopts fiberglass folder steel wire, and profile is rough, and cost is bigger.And original welded-steel plate construction, the fan housing window is very easily thrown with fan housing mutually because of welding deformation causes fan.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, thereby a kind of fan housing of motor is provided, and can reduce windage, is convenient to effective air intake, improves effective wind rate and blast, and can reduce the temperature rise of motor.
The technical scheme that provides according to the utility model, described motor fan housing, comprise air draught mouth and the end shield window installed by trip bolt and spring washer on the end shield, has air admission hole on the end shield window, described end shield comprises the fan housing circle of tubulose, be installed with circular right end plate at fan housing circle endoporus right-hand member by cone shape bracing ring, on the fan housing circle, be provided with hanger and installing hole.
Described air draught mouth right-to-left internal diameter shrinks gradually.And described air draught mouth comprises give vent to anger straight tube and the wind-guiding conical tube formation that is positioned at left end, wind-guiding conical tube right-to-left internal diameter shrinks gradually, wind-guiding conical tube left part is connected with the straight tube right part of giving vent to anger, have outwardly directed flange in wind-guiding conical tube right part, on flange, offer some bolts hole.
The utility model is used to install the motor external fan, can reduce windage, is convenient to effective air intake.Simultaneously the cooling air of fan housing is introduced between the fin of motor effectively and uniformly, reduced windage, improved effective wind rate and blast, reduced the temperature rise of motor.This is simple and practical, welding deformation is little, and good looking appearance, and fan housing structure of motor commonly used has reduced the mould input cost.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a right view of the present utility model.
Fig. 3 is the structural representation of another kind of air draught mouth in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As Fig. 1～shown in Figure 2: the utility model mainly is made of end shield 1, fan housing circle 1a, bracing ring 1b, right end plate 1c, hanger 1d, installing hole 1e, air draught mouth 2, the straight tube 2a that gives vent to anger, wind-guiding conical tube 2b, flange 2c, trip bolt 3, spring washer 4 and end shield window 5 etc.
This motor fan housing, comprise the air draught mouth 2 and end shield window 5 installed by trip bolt 3 and spring washer 4 on the end shield 1, has air admission hole on the end shield window 5, described end shield comprises the fan housing circle 1a of tubulose, be installed with circular right end plate 1c at fan housing circle 1a endoporus right-hand member by cone shape bracing ring 1b, on fan housing circle 1a, be provided with hanger 1d and installing hole 1e.
Described air draught mouth 2 right-to-left internal diameters shrink gradually.And described air draught mouth 2 comprises give vent to anger straight tube 2a and the wind-guiding conical tube 2b formation that is positioned at left end, wind-guiding conical tube 2b right-to-left internal diameter shrinks gradually, wind-guiding conical tube 2b left part is connected with the straight tube 2a right part of giving vent to anger, have outwardly directed flange 2c in wind-guiding conical tube 2b right part, on flange 2c, offer some bolts hole.
The utility model is used to install the motor external fan, reduces windage, is convenient to effective air intake.Simultaneously the cooling air of fan housing is introduced between the fin of motor effectively and uniformly, reduced windage, improved effective wind rate and blast, reduced the temperature rise of motor.This is simple and practical, welding deformation is little, and good looking appearance, and fan housing structure of motor commonly used has reduced the mould input cost.
