Abstract
The utility model relates to the technical field of variable frequency motors, and discloses a mounting structure for a fan of a variable frequency motor. The mounting structure comprises a main motor and the fan, and is characterized in that a motor outlet box and a motor rear end cover are arranged on the main motor; a fan motor, a fan cover and fan blades are arranged on the fan; a small flange is arranged at the front end of the fan motor, and is fixed on the motor rear end cover through screws; a transition sleeve is arranged at the shaft end of the rear end of the fan motor; the fan blades are connected with the shaft end of the fan motor through the transition sleeve; outgoing lines of the fan motor are arranged in the motor outlet box; and the fan cover is arranged outside the motor fan. The mounting structure is rational in design, simple and convenient to connect, and can run stably; and the fan motor is completely separated from the fan cover, and the transition sleeve is arranged at the shaft end of the fan motor, so that forms of the fan blades and the fan cover of the variable frequency motor can be randomly selected.
Description
Technical field
The utility model relates to the technical field of variable-frequency motor blower fan, specifically a kind of mounting structure of variable-frequency motor blower motor.
Background technology
The application of controlling at present motor is more and more extensive, controls in motor and take variable-frequency motor as main, and its application is more more extensive, therefore the performance requirement of variable-frequency motor, degree easy to use and flexible design degree has all been proposed to very high requirement.Current variable-frequency motor blower fan is partly made as a whole standard component and is designed by blower fan manufacturer, its blower motor is arranged on fan housing, as a whole with the fan housing assembling, its design is difficult to meet the wind path demand of all motors, brings significant limitation to the design of variable-frequency motor.Be subject to the impact of its structure, motor manufacturer can only carry out the design of motor and blower fan fitted position according to blower fan, the fan housing with blower motor is fixed on to motor rear end and covers.Because blower motor is heavier, whole weight all is added on fan housing, then is fixed on motor rear end by fan housing and covers, and causes the fan housing distortion, produces the vibrations noise in operation process very large simultaneously.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, provide a kind of reasonable in design, simple in structure, operate steadily, the wiring facility, blower motor separates fully with fan housing, can choose at random variable-frequency motor fan blade, fan housing form, break the place one's entire reliance upon situation of blower fan factory of variable-frequency motor fan blade.
The technical scheme that the utility model adopts is: a kind of mounting structure of variable-frequency motor blower fan, comprise main motor, blower fan, it is characterized in that main motor is provided with motor wire outlet box, back end cover for motor, blower fan is provided with blower motor, fan housing, fan blade, be provided with little flange at the blower motor front end, by screw, little flange being fixed on to motor rear end covers, the shaft extension end of blower motor rear end is provided with spacer shell, fan blade is connected with the blower motor shaft extension by spacer shell, the outlet of blower motor is located in motor wire outlet box, and the motor fan outside is provided with fan housing.
Cover because the little flange of blower motor front end is fixed by screws in main motor rear end, be integral with main electrical mechanisms, its blower motor outlet and motor outlet wire are incorporated in motor wire outlet box, make motor easy to manufacture, easy to use.Fan housing separates with blower motor, increased the selectivity of fan blade and fan housing, can select suitable fan blade, fan housing according to different demands, the weight that simultaneously fan housing need not bear blower motor, make the vibrations reducing noise of fan housing in whole variable-frequency motor operation process.
The utility model is reasonable in design, simple in structure, easy to manufacture, operates steadily, the wiring facility, and blower motor separates fully with fan housing, can choose at random the structure of variable-frequency motor fan blade, fan housing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1, motor wire outlet box, 2, back end cover for motor, 3, hold-down screw, 4, blower motor, 5, the main body motor, 6, little flange, 7, fan housing, 8, spacer shell, 9, fan blade.
Embodiment
As shown in Figure 1, a kind of mounting structure of variable-frequency motor blower fan, comprise main motor 5, blower fan, main motor is provided with motor wire outlet box 1, back end cover for motor 2, blower fan is provided with blower motor 4, fan housing 7, fan blade 9, be provided with little flange 6 at blower motor 4 front ends, by screw 3, little flange being fixed on to motor rear end covers, the shaft extension end of blower motor rear end is provided with spacer shell 8, fan blade is connected with the blower motor shaft extension by spacer shell, the outlet of blower motor is located in motor wire outlet box, and the motor fan outside is provided with fan housing 7.Blower motor 4 front ends are provided with little flange 6 and contact and utilize hold-down screw 3 to be fixed on back end cover for motor 2 by face, make blower motor 4 and main body motor 5 form an integral body, main body motor 5 is provided with motor wire outlet box 1, blower motor 4 and main body motor 5 form an integral body, the outlet of the outlet of main body motor 5 and blower motor 4 all is incorporated in motor wire outlet box 1, blower motor 4 rear ends are provided with fan blade 9, by spacer shell 8, be connected on the shaft extension of blower motor 4, blower motor 4 outsides are provided with fan housing 7 and are connected with the back end cover for motor 2 on main body motor 5.During final assembly, after main motor 5 is assembled, by little flange 6, utilize blower motor 4 hold-down screw 3 to be fixed on the back end cover for motor 2 of main motor 5, by fan blade 9, by spacer shell 8, be assembled on the shaft extension end of blower motor again, outlet on outlet on blower motor 4 and main body motor 5 is incorporated in motor wire outlet box 1, fan housing 7 is assembled on back end cover for motor 2.The utility model is because blower motor 4 and main body motor 5 form an integral body, blower motor separates with fan housing, can be according to the demand of different motor air channels, select suitable fan blade, fan housing, increased the performance that chooses at random of fan blade and fan housing, broken the limitation of the overall design brought as a main body by blower fan in variable-frequency motor design in the past, the weight that fan housing need not bear blower motor simultaneously, make the vibrations reducing noise of fan housing in whole variable-frequency motor operation process.
