Abstract
The utility model discloses a cooling tower blower transmission shaft, which comprises a connection shaft and half couplers with the same connection structure on both ends of the connection shaft, wherein each half coupler comprises an outer flange disc, an elastic dowel pin, a bolt, a retarder or a shaft sleeve on the end of the motor and a connection shaft flange disc; the outer flange disc is fixed on the retarder or a motor shaft through the shaft sleeve, and the outer flange disc is fixedly connected with the shaft sleeve through the bolt, and the outer flange disc is fixedly connected with the connection shaft flange disc on the connection shaft through the elastic dowel pin and the bolt; and the elastic dowel pin consists of a column sleeve and an elastic sleeve which forms an integral structure with the column sleeve, and the elastic sleeve is in interference fit with a fixed hole on the outer flange disc. The cooling tower blower transmission shaft reduces the abrasion of the elastic sleeve and the outer flange disc, and prolongs the service life of the elastic sleeve, and not only plays the effect on compensating the relative displacement of the two shafts and buffering effect, but also can play the shock reduction and shock absorption effect; moreover, the coaxiality of the two half couplers are ensured, thereby reducing the vibration. The connection is more stable and more reliable, so that the cooling tower blower transmission shaft is particular applicable to the blower with large span.
Description
One, technical field:
The utility model relates to a kind of component of blower fan of cooling tower: transmission shaft.
Two, background technique:
Transmission shaft is as a vitals of industrial cooling tower blower fan, and it mainly acts on is to connect blower fan retarder and motor, transmits motor power.The blower fan transmission shaft generally adopts elastic coupling flexible coupling with coupling, so transmission shaft becomes quick condition.
At present, transmission shaft mainly contains two kinds of structural types with coupling, and a kind of is the metal diaphragm coupling; Another kind is an elastic dowel pin shaft coupling, all simple in structure, easy accessibility.But wherein, diaphragm coupling radially big with the angular displacement compensation rate is easy to generate the disalignment phenomenon, causes vibration, and simultaneously, the vibration damping and the vibration absorption ability of metal diaphragm itself are relatively poor, and buffer capacity is little.Elastic dowel pin shaft coupling is because pin and column pin hole are Spielpassung, is easy to generate slide relative and weares and teares, and shortened working life, and its application area also is very limited.
Three, summary of the invention:
The utility model is exactly to solve now with the problems referred to above that exist in the technology, provide a kind of wearing and tearing little, vibration damping, absorbing performance are good, change convenient, have compensation diaxon relative displacement and shock-absorbing capacity, can be applicable to the blower fan of cooling tower transmission shaft on big span and the high-speed fan.
For addressing the above problem, technical solution of the present utility model is: a kind of blower fan of cooling tower transmission shaft, it comprises coupling shaft and the identical half-coupling of coupling shaft two ends linkage structure, and each half-coupling includes the axle sleeve and the coupling shaft flange plate of outward flange dish, spring column pin, bolt, retarder or motor side; The outward flange dish is fixed on retarder or the motor shaft by axle sleeve, itself and shaft room bolt tightening, and the coupling shaft flange plate on outward flange dish and the coupling shaft is in the same place by spring column pin and bolt; It is characterized in that: spring column pin is formed by column sleeve with the into a single integrated structure elastic sleeve of column sleeve, and the fixed hole on elastic sleeve and the outward flange dish adopts interference fit.The friction that can avoid the fixed hole on elastic sleeve and the outward flange dish to produce like this, thereby reduced wearing and tearing, prolonged the working life of spring column pin, the elastic sleeve on the spring column pin, have the certain deformation ability, can compensate diaxon radially and angular displacement by energy of deformation.The energy of deformation of elastic sleeve can play the effect of vibration damping and absorbing.Has certain buffer capacity.
Above-mentioned described axle sleeve of the present utility model adopts tapered hub, like this when transmission shaft need be dismantled maintenance, needn't mobile again retarder and motor, and be very easy to daily maintenance of user and maintenance.
Be provided with the seam linkage structure between above-mentioned described spring column pin of the present utility model and the coupling shaft flange plate.Guarantee the coaxality of coupling shaft flange plate and outward flange dish, reduced unbalanced force, simultaneously, played the effect of transmitting torque.
The column sleeve of above-mentioned described spring column pin of the present utility model is provided with annular groove.This annular groove increased and elastic sleeve between friction, make the combination of the two more firm.
Because the utility model has adopted such scheme, it has reduced the wearing and tearing of elastic sleeve and outward flange dish, prolonged the working life of elastic sleeve, not only can play the effect of compensation diaxon relative displacement and buffering, can also play the effect of vibration damping and absorbing, and guaranteed the coaxality of two half-couplings, reduced vibration.Connect more firmly, reliable, the blower fan of suitable big span uses.It is simple in structure, and is easy to maintenance, long service life.
Four, description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Five, embodiment
