Description
Technical field
The utility model relates to transmission device technical field, is specifically related to a kind of deceleration device.
Background technology
Cooling tower is mainly used in each industrial circle and the civil air conditioner cooling systems such as electric power, metallurgy, petrochemical industry, weaving, and energy consumption is occupied larger ratio in industrial production.Cooling tower is to take the used heat producing in industrial production to capital equipment in atmosphere, and these used heat enter cooling tower in the mode of hot water, makes hot water cooling, and then return in industrial production through pervaporation and heat loss through conduction; The heat of hot water to be passed to air, need to for cooling tower a large amount of fresh natural air is provided and used heat air discharged to outside tower, this effect is that the blower fan of dependence cooling tower air duct completes.
The blower fan of current domestic cooling tower air duct generally adopts belt speed reducer or planet-gear speed reducer as deceleration device, between machine shaft and reductor, by power transmission shaft or belt, connect, this just causes the spacing of machine shaft and reductor oversize, make outside the air duct of motor in cooling tower, cause cooling tower noise large, affect structural stability, unfavorable to health.
Utility model content
The utility model is intended to provide integral fan deceleration device in a kind of cooling tower air duct, to solve the large problem of cooling tower noise in prior art.
Integral fan deceleration device in cooling tower air duct in this programme, comprise the motor that is positioned at air duct and the reductor that is positioned at air duct, between described motor and speed reducer, by flange, connect as one, described reductor comprises output shaft, described motor comprises motor shaft, and described motor shaft and described output shaft are by gear drive.
Compared with prior art, the utility model has the advantages that: motor shaft is equal to reductor power shaft, speed reducer output shaft is equal to fan shaft, motor and speed reducer directly connects as one, volume reduces, vibrations reduce, size and the area occupied of motor, reductor have been reduced, save space, reduced cost, saved power transmission shaft, transmission efficiency improves, and motor, reductor integral body are placed in cooling tower air duct, make air duct become the natural cover for defense of motor, reductor noise transmission, reduced noise.
Further, described motor and reductor flange connections adopt double oil seal sealing, simply effective, have guaranteed the sealing of reductor in the situation of running up.
Further, described reductor also comprises housing, reduction gearing, and described reduction gearing is hypoid circular cone driving gear, the driven gear of a pair of employing curve profile of tooth, and wherein driving gear, driven gear axis become 90 degree antarafacials vertical; Motor shaft is connected by flat key with driving gear, and driven gear and output shaft are with bolts, and compact conformation is convenient to install in cooling tower air duct, has also saved the worry that belt feeder brings because of belt elongation, the inconvenience of also having avoided air duct that reductor is installed outward.
