The reduction that traditional bracker fan head-shaking device will realize motor station speed mainly adopts V belt translation and Chain conveyer, realize yaw motion and mainly use cam mechanism.The narrow limitation that Chain conveyer and V belt translation, cam mechanism have it serious.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of fan head-shaking device, and it comprises:
Electric fan, motor, a client link of electric fan and motor;
Speed-change gear box, speed-change gear box is made up of first order inside engaged gear group and second level inside engaged gear group;
First order inside engaged gear group, the motion that motor produces and transmission of power are to the first internal gear and the first external gear;
Second level inside engaged gear group, the motion that first order inside engaged gear group is transmitted and transmission of power are to secondary annulus and the second external gear;
Worm-and-wheel gear, the motion that speed-change gear box spreads out of and power pass to worm and wheel;
Double rocker mechanism, double rocker mechanism is made up of rocking bar b and rocking bar d, connecting rod and frame, realizes overall yaw motion.
The motion that motor produces and power one client link electric fan, the other end and speed-change gear box connect, and the Movement transmit of speed change gear chest, to worm-and-wheel gear, drives double rocker mechanism motion to realize the action of yaw by worm-wheel shaft.
Speed-change gear box has the one the second two-stage inside engaged gear groups to form, the power of the first internal gear of first order inside engaged gear from motor, first internal gear engages with the first external gear, first external gear is coaxial with the secondary annulus of second level inside engaged gear group, secondary annulus and the second external gear engagement driving.
Worm gear and worm meshing transmission, worm screw is coaxial with second level inside engaged gear group external gear.
Fixing being bound up in one end of the connecting rod of worm-wheel shaft and double rocker mechanism, worm gear rotarily drives connecting rod and moves in a circle around worm-wheel shaft, connecting rod drives two rocking bars to do reciprocally swinging around hinge around the circular movement of worm-wheel shaft, which achieves the yaw motion of bracker fan.
After have employed above-mentioned improvement project, change and should be the huge shortcoming in space required for V belt translation and Chain conveyer, reduction that can be quantitative to the rotating speed of motor, for fan swing mechanism we selected double rocker mechanism replace cam mechanism, relative to cam mechanism, double rocker mechanism has the advantages that movement locus is easy to calculating, the accuracy of manufacturing of cam mechanism requires high, and trajectory calculation is complicated.
