There are two kinds of shaking control, one is to drive the connecting rod to shake its head through the reduction gear, that is, the gear will slip without shaking its head. The other is that the synchronous motor directly controls the fan to shake its head. In addition to the vibration motor itself, it is also possible that the control circuit and switch are broken. If it is a remote control fan, it may also be a problem of transistor driving. The power of the fan swing mechanism comes from the worm at the rear end of the motor shaft, which drives the four-bar linkage to swing back and forth after two-stage speed change. Shake your head failure is mainly divided into two situations: not shaking your head and shaking your head. One of the reasons for not shaking your head is that shaking your head is blocked, which is caused by the deformation and bending of the connecting rod. At this time, there will be a bang, and the deformed connecting rod can be removed and taken out after shaping; Second, the transmission is out of order, so that the power cannot be transmitted. Can check the rack bar, swing plate, gear box, clutch, etc. If it is found that there are phenomena such as falling off, foreign objects stuck, and serious wear and tear, it is necessary to eliminate or replace the lost parts.

Shaking head is not only caused by the broken wire rope or loose head in remote control clutch or shaking head control device. If the steel wire breaks, a new steel wire flexible shaft can be replaced. If the tie head is loose, just re-fix the metal head of the casing. According to whether the front-end oil-bearing holds the shaft or the rear-end bearing holds the shaft, first find some oil drops at the two bearing holes, then clamp the front shaft with a vise and rotate the shaft forcibly. If you still can't rotate at this time, you can gently tap the shaft end several times with a hammer. Generally, you can rotate the shaft slowly while rotating it, so that the shaft end cover can be removed from the motor rotor, and the other end cover can be removed by soaking. Soak the bearing with alcohol or other organic solvents, then clean the dirt in the bearing, then dry it, put the container with proper amount of engine oil on the stove and heat it to 120℃, then put the front and rear covers in the oil and cook for a few minutes until there are no bubbles in the oil, then take it out and cool it, and then install it. When installing the machine, pay attention to the uniform tightening force when tightening bolts, and at the same time, extend the rotating shaft without getting stuck.
