Preferably, said transmission device comprises intermeshing one first gear and one second gear, and said second gear is connected with said motor, and said first gear is connected with said speed reduction gearing through one first gear wheel shaft.
Preferably, said speed reduction gearing comprises intermeshing one the 3rd gear and one the 4th gear, and said the 3rd gear drives said the 4th gear through one second gear wheel shaft, and said the 3rd gear is connected with said first gear through said first gear wheel shaft.
Preferably, said first gear is the identical gear of the number of teeth with said second gear.
Preferably, the number of teeth of said the 3rd gear is less than the number of teeth of said the 4th gear.
Preferably, said the 4th gear is connected with said chain cable fairlead.
Preferably, said Electric Chain Blocks also comprises an electric cabinet and a power-transfer clutch, and said electric cabinet is arranged at said motor top, and said power-transfer clutch is connected with said speed reduction gearing through said transmission device.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the utility model.
The positive progressive effect of the utility model is: the utility model has increased by one group of gear of only making transmission device in Electric Chain Blocks; Changed the placement location of drg; Avoided axis in-line all of axis and drg of axis, the motor of chain cable fairlead, made that the electric block interior layout is more flexible.Realized having reduced the volume of electric block under the condition of equal transmitting ratio and power.It can adapt to the installation of all blower fan tower barrels and need not to consider interface problem.
Description of drawings
Fig. 1 is used for the structural representation of the Electric Chain Blocks of blower fan tower barrel for the utility model.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As shown in Figure 1, the Electric Chain Blocks that the utility model is used for blower fan tower barrel is provided with an electric block casing 1, in electric block casing 1, comprises a motor 2 as driving arrangement, a speed reduction gearing, a drg 10, a chain cable fairlead 7 and a transmission device.
Wherein, said transmission device comprises intermeshing one first gear 3 and one second gear 4.Said speed reduction gearing comprises intermeshing one the 3rd gear 5 and one the 4th gear 6.Second gear 4 is connected with motor 2, and first gear 3 is connected with the 3rd gear 5 through one first gear wheel shaft 8.The 3rd gear 5 drives the 4th gear 6 through second gear wheel shaft 9.The 4th gear 6 is connected with chain cable fairlead 7.
When using electric block, first starter motor 2, the output shaft through motor 2 drives second gear 4 and rotates, and then drives first gear 3 and rotate.Preferably, first gear 3 is identical with the number of teeth of second gear 4, and a driving torque does not play deceleration effort.Then, first gear 3 drives 5 rotations of the 3rd gear through first gear wheel shaft 8, and the 3rd gear 5 drives the 4th gear 6 through second gear wheel shaft 9 again, forms speed reduction gearing, with the rotating speed reduction of motor output.Preferably, the number of teeth of the 3rd gear 5 is less than the number of teeth of the 4th gear 6, and the rotating speed of such the 4th gear 6 is lower than the 3rd gear 5, realizes the purpose of rev down.Then, the 4th gear 6 drives chain cable fairlead 7 runnings, controls chain folding and unfolding good and sound on the chain cable fairlead 7 with this.In the operating process, control chain cable fairlead 7 forward or reverse, pack up or put down thereby drive the chain that is installed on the chain cable fairlead 7 through the rotation direction of motor 2.
In addition, a drg 10 is set also on first gear 3, drg 10 is connected with the 3rd gear 5, control whole reducing mechanism with this and slow down, stop or keeping halted state.Simultaneously, preferably, a power-transfer clutch 11 is set on second gear 4, can controls and separate between first gear 3 and second gear 4 or the engagement transferring power.Like this, drg 10 forms a cover duplicate protection system with power-transfer clutch 11, is convenient to control the motion of Electric Chain Blocks, makes operation safe.
Certainly, the utility model Electric Chain Blocks can also comprise an electric cabinet 12, electric cabinet 12 is arranged at the top of motor 2.Motor 2 is arranged on a side of electric block casing 1, and whole transmission device, drg and speed reduction gearing all are arranged at the opposite side of electric block casing 1.This topology layout makes that the structure arrangement of gear and gear wheel shaft is tight, makes full use of the space in the Electric Chain Blocks casing.And the motor of selecting for use in the utility model is a micro-machine, under the prerequisite of proof strength, adopts the little and few gear of the number of teeth of gear thickness, thereby has significantly reduced the shared space size of driving system.
To sum up, the block construction that the utility model has changed each parts in the electric block casing has realized having reduced the volume of electric block under the condition of equal transmitting ratio and power.And the utility model has also been avoided the axis in-line of axis, chain cable fairlead axis and the motor of drg, makes that the electric block interior layout is more flexible.
Though more than described the specific embodiment of the utility model, it will be understood by those of skill in the art that these only are casehistorys, the protection domain of the utility model is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite of principle that does not deviate from the utility model and essence, but these changes and modification all fall into the protection domain of the utility model.
