Causes of jitter in hard tooth surface gear reducer during operation

The reasons why the hard tooth surface gear reducer vibrates during operation can be analyzed from the following aspects:
1. Gear manufacturing errors
In the manufacturing process of hard tooth surface gear reducer, the machining accuracy of the gear is crucial to the smooth operation of the reducer.If the manufacturing accuracy of the gear is poor, and there are problems such as tooth shape error, base pitch error, tooth direction error, etc., it will cause uneven instantaneous speed of the gear during the meshing process, thus causing the vibration of the reducer.
The way to solve this problem is to improve the manufacturing accuracy of gears. Precision processing equipment and measuring instruments can be used to ensure that the errors of the gears are within the allowable range.At the same time, the assembly accuracy must be strictly controlled during the assembly process to ensure that the gears are in good meshing condition.
2. Bearing failure
The bearing in the hard tooth surface gear reducer is an important component that supports the gear shaft. If the bearing fails, such as bearing damage, excessive bearing clearance, etc., it will increase the support instability of the gear shaft, causing the reducer to shake. .
The way to solve this problem is to regularly check the working status of the bearings, replace damaged bearings in time, and adjust the bearing clearance to ensure the normal operation of the bearings.At the same time, when selecting bearings, you should choose bearing brands and models with reliable quality and stable performance.
3. Unbalanced transmission system
An unbalanced transmission system in a hardened gear reducer can also cause the reducer to vibrate during operation.Causes of unbalanced transmission systems may include wear of transmission parts, uneven mass distribution of transmission parts, etc.
The way to solve this problem is to perform balance detection and adjustment on the transmission system, and to eliminate unbalanced factors by adjusting the balance weight.At the same time, the wear of transmission parts should be checked regularly and seriously worn transmission parts should be replaced in time.
4. Insufficient basic strength
The insufficient basic strength of the hard tooth surface gear reducer will also cause the reducer to vibrate during operation.Reasons for insufficient foundation strength may include unreasonable foundation design, poor foundation manufacturing quality, etc.
The way to solve this problem is to strengthen the foundation design to ensure that the foundation has sufficient strength and stability.The rigidity and stability of the foundation can be improved by increasing the thickness of the foundation plate and adding reinforcement ribs.At the same time, when installing the reducer, ensure that the installation position of the reducer is correct and the foundation level meets the requirements.
5. External interference factors
The hard tooth surface gear reducer will also be affected by external interference factors during operation, such as motor vibration, load mutation, etc.These interference factors will cause the vibration of the reducer.
The way to solve this problem is to take corresponding vibration reduction and anti-interference measures, such as installing a vibration absorber between the motor and the reducer to control the load smoothly, etc.At the same time, the grounding and shielding measures of the reducer should be checked regularly to ensure that the reducer is not affected by external electromagnetic interference.
