What is the reason for the abnormal noise of the headstock of the lathe headstock and the abnormal n

The day before yesterday, when I walked through the grass by the water again, I looked at the place where we walked in the rain, and I stopped, as if I saw your shadow. Tonight, I think of you, I can't sleep, at this moment you should be in his arms, I wonder if you have a dream at this moment, whether you have a dream in your dream, whether you have been to a place we have been in your dream. Remember you once said:

No matter how long we can love each other or how far we can go, but we have been here, we should have no regrets. Perhaps, this sentence is our summary from now on, and maybe we will never see each other again. However, after that night, every day when I went to work, I would change the route I walked, and I always hoped to meet you unexpectedly in front of that store, smile knowingly, and feel the beauty of that encounter without saying anything.

Tonight, when I think of you, my heart is always full of melancholy. No matter what happens to us in the future, on this early autumn night, in the silence of the night, I want to say to you: If An Yan is here, I will be fine, and if you bloom in the next spring, I will come with a breeze.

I have a friend who plays this, you and me, add me q and reply to you tomorrow.

Hello, the reason is (1) the dynamic balance of the spindle parts is not good.

2) The gear meshing gap is uneven or severely damaged.

3) The bearing is damaged or the transmission shaft is bent.

4) Poor gear accuracy.

5) Poor lubrication.

Troubleshooting:

1) The dynamic balance of the spindle components is not good, and the dynamic balance is redone.

2) The gear meshing clearance is uneven or seriously damaged, the clearance is adjusted or the gear is replaced, 3) the bearing is damaged or the transmission shaft is bent, repair or replace the bearing, straighten the transmission shaft, the reason is (1) the dynamic balance of the spindle components is not good, (2) the cavity return gear meshing clearance is not uniform, or seriously damaged, (3) the bearing is damaged or the transmission shaft is bent (4) the gear accuracy is poor, (5) the lubrication is poor troubleshooting methods: (1) the dynamic balance of the spindle components is not good, and the dynamic balance is redone (2) the gear meshing clearance is uneven or seriously damaged Adjust clearance or replace gears (3) Bearing damage or bending of the transmission shaft Repair or replace the gear round bearing, straighten the transmission shaft (4) Poor gear accuracy Replace the gear (5) Poor lubrication Adjust the amount of lubricating oil to maintain the cleanliness of the headstock.

If there is no problem with the load, there is no overload, the servo motor may be improperly adjusted or the gain is not adjusted. The operation steps are as follows; Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is a kind of indirect transmission device of auxiliary motor. The servo motor can make the control speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object.

DC servo motors can be used in spark machines, manipulators, precision machines, etc. It can be equipped with a standard encoder and a speed tester with high analysis of 2500P R at the same time, and can be equipped with a gearbox to bring reliable accuracy and high torque to the mechanical equipment. The speed regulation is good, and the output power per unit weight and volume is the highest, which is greater than that of AC motors and far more than stepper motors.

The moment fluctuations of the multi-level structure are small. Servo motors are used inside closed rings. That is to say, it transmits signals to the system at any time, and at the same time uses the signals given by the system to correct its own operation.

The servo motor can also be controlled by a microcontroller. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!

Put the rear wheels of the car up, start the engine, hang up the high-speed gear, check the oscillation of the transmission shaft, if the oscillation is the largest when the speed drops, it means that the oscillation and sound caused by the transmission imbalance, otherwise it is the sound caused by looseness. If the sound is not serious, you can drive back for repair, and if it is serious, it should be stopped immediately for repair.

The main causes of failure: (1) The transmission shaft is bent and dented, resulting in unbalance during operation, causing swing and noise. (2) The transmission shaft is improperly installed, and the universal joint forks at both ends of the transmission shaft are not installed in the same plane.

Or the original balance plate is not put back in place, which destroys the balance state, causing sound and vibration. (3) The connecting bolts of the universal joint joint disc are loose. (4) The fixing bolt of the middle bracket of the transmission shaft is loose.

The main signs of the transmission shaft, the universal joint loose sound transmission shaft, and the universal joint loose sound fault: when the car starts, the body trembles, and the impact sound of "click, click" can be heard, and the sound is more obvious with the change of speed during driving.

The main reasons for the failure: (1) The universal joint cross shaft and the needle roller are worn loosely or the needle roller is broken. (2) The spline teeth of the transmission shaft and the spline groove of the universal joint sliding fork are worn loosely.

3) The spline teeth of the second shaft of the transmission and the flange slot are too worn. (4) The bolts of each connection part are loose.

Fault diagnosis and elimination: (1) Shake the transmission shaft by hand, if the spline teeth and spline groove are worn, there will be a loose feeling. (2) Relax the hand round eggplant high brake, shake the hand brake disc back and forth with your hand, if there is an opening, that is, the second shaft spline tooth and the flange spline groove of the transmission have been worn and loose.

After inspection, if the above fault is not serious, you can continue to drive, if it is serious, it should be removed and repaired.

The indication of the middle bearing of the transmission shaft is that the car makes a "woo, woo" sound when driving, the faster the speed, the louder the sound, and the sound is extremely obvious when coasting in neutral gear.

The main reasons for the ringing of the middle bearing of the transmission shaft: (l) the bearing is too worn loose or lacks lubricating oil. (2) The rubber sleeve of the bracket is damaged, or the position of the bracket is incorrect, and the bearing is not strong and produces a sound.

3) The journal of the bearing is worn too much, and the journal and the inner ring of the bearing rotate to produce a sound.

Fault diagnosis and elimination method: (1) When the intermediate bearing is found to have a ring, the bearing position should be checked first. (2) If it is not deflected, the bracket should be removed for disassembly and inspection to see whether the bearing is too worn, or lacks lubricating oil, and whether the bracket rubber sleeve is damaged.

Repair or replace if necessary.

If there is an abnormal sound in the transmission shaft that needs to be checked, it may be that the intermediate support bearing of the transmission shaft is worn too much, the axial clearance and radial clearance are increased, and the sound is made during rotation; It may also be an abnormal sound caused by wear or rust of the transmission shaft cross shaft; The spline of the transmission shaft is seriously worn, resulting in too large a gap between the joint part of the gearbox and the abnormal sound when transmitting power.

Causes and solutions of abnormal noise of automobile transmission shaft: 1. The reason for the abnormal sound of the transmission shaft is generally that the transmission shaft is bent and dented, resulting in unbalance during operation, causing swing and noise; 2. In addition, the transmission shaft is not installed properly, the universal joint forks at both ends of the transmission shaft are not installed in the same plane, or the original balance piece is not installed back in place, so that the balance state is destroyed, the connecting bolts of the universal joint joint disc are loose, and the fixing bolts of the intermediate bracket of the transmission shaft are loose, etc., will cause the transmission shaft to make abnormal noise; 3. The solution to the abnormal sound of the transmission shaft is to start the car engine to hang up the high-speed gear, check the oscillation of the transmission shaft, if the oscillation is the largest when the speed drops, it means that the oscillation and sound caused by the transmission imbalance, otherwise it is the sound caused by looseness.

If the sound is not serious, you can drive back for repair, and if it is serious, it should be stopped immediately for repair.

Automobile drive shaft abnormal noise treatment method: 1. Changing the speed and throttle test during driving, if there is a "click, click" impact sound, it is likely that the bearing is worn loose or lack of oil, and the bearing should be repaired or replaced with sufficient lubricating oil; 2. When the vehicle starts, there is a "bang" sound or the sound is more messy, such as when reversing backwards on a gentle slope, there is a continuous sound of "horn, horn", which is generally broken, broken or lost by the needle, and should be replaced with a new product; 3. Periodic abnormal noise, the faster the speed, the louder the sound, should check whether the transmission shaft is bent, whether the balance weight falls off, and whether the spline is loose; 4. If the continuous vibration sounds, the intermediate bearing bracket washer should be checked; 5. Lift the car to hang the high-speed gear and check the oscillation of the transmission shaft. Especially when the accelerator pedal is lifted and the speed of the vehicle drops suddenly, if the oscillation is greater, the flange and the shaft tube are welded and skewed or the transmission shaft is bent; Check the technical condition of the universal joint fork and the intermediate shaft support, if the installation does not meet the requirements, the cross shaft and the needle roller are worn and broken and loose, so that the transmission shaft assembly is out of balance, it should be repaired or replaced.
