Abstract
A kind of synchronous transmission device of blower fan of cooling tower of the utility model, including cooling tower, the driven wheel being located in blower fan of cooling tower shaft, the driving wheel being fixed on the motor of cooling tower side, motor is three-phase induction motor, and driving wheel and driven wheel are synchronous pulley, and passes through synchronous band connection transmission.The utility model has accurate transmission ratio, can accurately control blower operating, and structure is simple, stable drive, can buffer, low energy consumption, reduces manufacture, runs the advantages such as low with maintenance cost.
Description
Technical field
The utility model belongs to cooling tower technical field, and in particular to a kind of transmission device of blower fan of cooling tower.
Background technique
The blower kind of drive of prior art cooling tower is essentially V-shape belt transmission, also useful gear-driven.V-type skin
V belt translation exists it cannot be guaranteed that the problems such as accurate transmission ratio, service life are shorter, maintenance is more frequent.During gear drive then exists
Heart square is restricted, need to lubricate and require high, manufacture and the high deficiency of maintenance cost.Also the blower fan of cooling tower having is directly and motor shaft
It is connected, but this structure will cause speed change difficulty, and the big revolving speed of blower diameter that heavy-duty motor is equipped with is low, motor is stupid
Weight, difficult to install, low efficiency, it is difficult to adapt to the different duty requirements of cooling tower, power wastage is larger, and consequence is undesirable.
Such as China Patent No. ZL 201220733982.1, the utility model patent of entitled " blower fan of cooling tower " are open
A kind of blower fan of cooling tower, including impeller and driving motor, impeller include the blade and wheel hub of inner hollow, wheel hub is equipped with
The shaft of power supply machine fixed axis hole has been respectively uniformly distributed the first spar and the second spar along axial direction in the blade, and first
Spar is equipped with gap between the outer end of blade, the first spar and the two sides and blade inner wall of the second spar.This cooling
Motor shaft and blower fan impeller shaft are exactly directly connected to by tower blower, therefore also there is that above-mentioned speed change is difficult, it is cold to be difficult to adapt to
But the larger defect of different duty requirements, power wastage of tower.
Utility model content
The utility model technical issues that need to address are overcome present in the blower fan of cooling tower kind of drive of the prior art
Defect, provide it is a kind of there is accurate transmission ratio, low energy consumption, and the axis of motor is stretched can shorter and motor bearings radial force
It is smaller, the cooling tower fun transmission of manufacture, operation and maintenance cost can be reduced.
The purpose of this utility model is achieved by following technical proposals:
The synchronous transmission device of blower fan of cooling tower, including cooling tower, the driven wheel being located in blower fan of cooling tower shaft, fixation
Driving wheel on the motor of cooling tower side, characterized in that motor is three-phase induction motor, and driving wheel is synchronous with driven wheel
Belt wheel, and pass through synchronous band connection transmission.
Toothed belt transmission had both had that the pressure that cogged engaged transmission is accurate, motor bearings is received is small, and motor bearings uses the longevity
Longer advantage is ordered, in turn avoids that central moment present in gear drive is restricted, the moment of inertia is big, need to lubricate and requires high, system
Make the disadvantage high with maintenance cost.Meanwhile Synchronous Transmission both had V-shape belt transmission be not required to lubrication, can exposed drive, flexibility
Good, center in turn avoids it and haves the defects that slip away from advantage unrestricted, at low cost, and due to relying on frictional force
Transmission and caused by the big defect of radial pressure.Because of cooling blower and some machinery with flywheel or uneven impact load
Equipment is different, and the characteristic for not needing motor has much slips, so with toothed belt transmission being feasible using synchronous pulley
, and be beneficial as described above.Furthermore it is by the inefficient of frictional drive that toothed belt transmission, which overcomes V-shape belt transmission,
Rate transmission deficiency, it is however generally that, the efficiency of V-type V belt translation all 92% hereinafter, and synchronous belt can reach 95-98%, this is right
In reducing energy consumption, energy saving meaningful.
Preferred embodiment, the mounting base of motor are equipped with the guide rail for adjusting height and adjusting with blower centre distance.Installation is adjusted
Examination is convenient.
Due to replacing more traditional V-shape belts with a synchronous belt, keep structure simple；Traditional V-shape belt transmission is examined
Consider satisfaction and usually require multiple straps, therefore the width of belt pulley is also bigger, causes the motor shaft for being applied to cantilever position
Torque and the radial load of bearing is also increase accordingly, and toothed belt transmission is only one, belt pulley relative narrower, to electricity
The load of arbor and bearing is relatively small, this facilitates the service life for extending motor and speed reducer.
Since belt is driven the alternate stress to motor shaft certainly existed, since using synchronous belt to motor shaft and bearing
Radial pressure is reduced, the amplitude for the alternate stress that motor bearings is received also just is reduced, direct meaning can exactly extend motor
Service life.
The beneficial effects of the utility model are:
1, toothed belt transmission has the advantages that structure is simple, stable drive；
2, the load that motor shaft and bearing are born is reduced；
3, easy for installation, motor and speed changer life-span are longer；
4, energy consumption reduces；
5, it manufactures, operation and maintenance cost reduce.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
In figure, cooling tower 1；Driven wheel 2；Mounting base 3；Motor 4；Driving wheel 5；Synchronous belt 6；Guide rail 7.
Specific embodiment
Elaborate with reference to the accompanying drawing to the embodiments of the present invention: the present embodiment is with the utility model technology
Implemented under premised on scheme, the detailed implementation method and specific operation process are given, but the protection of the utility model
Range is not limited to the following embodiments.
Embodiment: as shown in Figure 1, a kind of synchronous transmission device of blower fan of cooling tower, including cooling tower 1,1 top of cooling tower
Intermediate position have a blower, driven wheel 2 is connected in the shaft of blower fan of cooling tower, is connected with the mounting base of motor in cooling tower side
3, motor 4 is connected on motor mount 3, is connected with driving wheel 5 on motor 4.Driving wheel 5 and driven wheel 2 are synchronous pulley, and are led to
Cross the connection transmission of synchronous belt 6.Operating condition detection sensor, including water temperature sensor are equipped in cooling tower, sensor and controller connect
It connects, the output end of controller is connected to motor.The mounting base of motor, which is equipped with, to be adjusted height and adjusts and blower centre distance
Guide rail 7.There is guide rail 7 that installation and debugging can be made more convenient.
Toothed belt transmission had both had the accurate advantage of cogged engaged transmission, in turn avoided center present in gear drive
Square is restricted, the moment of inertia is big, need to lubricate and require high, manufacture and the high disadvantage of maintenance cost.Meanwhile Synchronous Transmission both has V
Type belt transmission be not required to lubrication, can exposed drive, the advantage that flexibility is good, central moment is unrestricted, at low cost, and due to contracting
The small width of belt wheel to reduce radial load suffered by motor shaft, and is caused due to being driven by frictional force
The big defect of radial pressure.
