Description
Technical field
The utility model relates to a kind of extruder motor, more specifically, relates to a kind of band fan extruder motor.
Background technology
The main motor of extruder can produce amount of heat when running, and needs cooling just can work long hours, and existing cool-down method mainly relies on independently that blower fan is air-cooled.But independently blower fan is air-cooled needs individual motor driven rotary, consume extra electric energy, general design blade is less, and quantity is also less, and rotating speed is lower.Independent blower fan due to air quantity less than normal, particularly when workshop temperature inside is higher, often cause coil to cross thermal overload, motor trips, and causes production line to stop a series of adverse effect such as production.
Summary of the invention
The utility model, for overcoming at least one defect described in above-mentioned prior art, provides a kind of band fan extruder motor.The utility model connects fan by driving on extruder electric machine main shaft, fan turns produces wind-force and accelerates motor surrounding air flowing speed, improve cooling rate, extend motor service life in hot environment, more save electric energy compared with independently blower fan, thus play the effect reduced costs.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions.
A kind of band fan extruder motor, comprise motor body, reductor and fan, described motor body drives reductor and fan turns, described reductor is connected between fan and motor body by shaft coupling, described fan comprises the rotating disk of fan blade and fixing described fan blade, and described fan blade is forward-curved blade.
The utility model connects fan by driving on extruder electric machine main shaft, and regulate rotation speed of the fan by reductor, fan turns produces wind-force and accelerates motor surrounding air flowing speed, improve cooling rate, extend motor service life in hot environment, avoid the use of independent blower fan, play saving electric energy, the effect reduced costs; The fan blade of described fan is forward-curved blade, compares the fan blade that conventional extruder is installed, and the air quantity of forward-curved blade is larger, reaches the object of effective temperature-reducing.Installed the fan blade of reductor additional, fan blade quantity increases, and area increases air quantity can be increased greatly, particularly under high-temperature condition, ensure that motor normal operation, and the increase of reductor can not the load of expanded motor, and power consumption can not increase.
Preferably, the bending angle that described fan blade front end is formed is 120 degree.
Preferably, the blade quantity of described fan blade is 48 ~ 60.
Preferably, the diameter of described fan is 3/5 ~ 1 of motor coil diameter.
Preferably, described reductor is variable speed reducer.
Preferably, described fan and reductor are also provided with protective cover outward, and the axial direction of described protective cover is provided with air vent hole, described protective cover be circumferentially with 6 ~ 8 through holes.
Preferably, the deceleration ratio of described reductor is 3 ~ 5:1.
Compared with prior art, the beneficial effects of the utility model are: connect fan by driving on extruder electric machine main shaft, and regulate rotation speed of the fan by reductor, fan turns produces wind-force and accelerates motor surrounding air flowing speed, improve cooling rate, extend motor service life in hot environment, more save electric energy compared with independently blower fan, thus play the effect reduced costs.Install reductor additional, fan blade quantity increases, and area increases air quantity can be increased greatly, particularly under high-temperature condition, ensure that motor normal operation, and the effect of reductor can not the load of expanded motor, and power consumption can not increase.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present utility model.
Embodiment
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.Describe position relationship in accompanying drawing only for exemplary illustration, the restriction to this patent can not be interpreted as.
embodiment 1
As described in Figure 1, a kind of band fan extruder motor, comprise motor body 1, reductor 2 and fan 3, described motor body 1 drives reductor 2 and fan 3 to rotate, described reductor 2 is connected between fan 3 and motor body 1 by shaft coupling, and described fan 3 comprises the rotating disk 32 of fan blade 31 and fixing described fan blade 31, and described fan blade 31 is forward-curved blade, more specifically, the bending angle that described fan blade front end is formed is 120 degree.The present embodiment connects fan 3 by driving on the main shaft of extruder motor body 1, and the rotating speed of fan 3 is regulated by reductor 2, fan 3 rotates and produces wind-force quickening motor surrounding air flowing speed, improve cooling rate, extend motor service life in hot environment, avoid the use of independent blower fan, play saving electric energy, the work reduced costs; The fan blade of described fan 3 is forward-curved blade, compares the fan blade that conventional extruder is installed, and the air quantity of forward-curved blade is larger, reaches the object of effective temperature-reducing; Installed the fan blade of reductor additional, fan blade quantity increases, and area increase makes air quantity greatly to increase, and more specifically, the blade quantity of described fan blade 31 is 56, and the diameter of described fan blade 31 is 3/5 ~ 1 of motor coil diameter.Described reductor 2 is variable speed reducer, and described fan 3 and reductor 2 are outer is also provided with protective cover 4, and the axial direction of described protective cover 4 is provided with air vent hole, described protective cover 4 be circumferentially with 6 ~ 8 through holes, for heat radiation.The deceleration ratio of described reductor 2 is 4:1.
When the motor body 1 of described extruder is started working, drive extruder main body, reductor 2 and fan 3 to run, reductor 2 can not the load of expanded motor main body 1, can not strengthen power consumption; Simultaneously, owing to having installed reductor 2 additional, the quantity of fan blade 31 compares the fan blade quantity increase of independent blower fan, and fan blade 31 is designed to the area that antecurvature formula structure increases fan blade 31, the increase of fan blade 31 quantity and area makes air quantity also increase greatly, particularly under high-temperature condition, ensure that the normal operation of motor body 1, do not produce additional heat and power consumption.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection range that all should be included in the utility model claim.
