The reasons for the shaking of the hard tooth surface gear reducer during operation can be analyzed from the following aspects:
1. Gear manufacturing error.
In the manufacturing process of hard tooth surface gear reducer, the machining accuracy of the gear is very important 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 section error, tooth direction error, etc., it will lead to the phenomenon of uneven instantaneous speed of the gear in the meshing process, which will cause the jitter of the reducer.
The solution to this problem is to improve the manufacturing accuracy of gears, and precision processing equipment and measuring instruments can be used to ensure that the errors of gears are within the allowable range. At the same time, the assembly accuracy should be strictly controlled during the assembly process to ensure that the meshing state of the gear is good.
2. Bearing failure.
The bearing in the hard tooth surface gear reducer is an important part to support the gear shaft, if the bearing fails, such as bearing damage, bearing clearance is too large, etc., it will lead to the increase of the support instability of the gear shaft, thereby causing the shake of the reducer.
The way to solve this problem is to check the working condition of the bearing regularly, replace the damaged bearing in time, and adjust the bearing clearance to ensure the normal operation of the bearing. At the same time, when selecting bearings, the brand and model of bearings with reliable quality and stable performance should be selected.
Third, the transmission system is unbalanced.
The imbalance of the transmission system in the hard tooth surface gear reducer will also cause the reducer to shake during operation. The causes of unbalanced transmission systems may include wear and tear of transmission parts, uneven mass distribution of transmission parts, etc.
The solution to this problem is to perform balance detection and adjustment of the drivetrain, and eliminate the unbalance factor by adjusting the balance counterweight. At the same time, the wear and tear of the transmission parts should be checked regularly, and the transmission parts with serious wear should be replaced in time.
Fourth, the foundation strength is insufficient.
The insufficient basic strength of the hard tooth surface gear reducer will also lead to the reducer shaking during operation. The reasons for insufficient foundation strength may include unreasonable foundation design, poor foundation manufacturing quality, etc.
The solution to 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 increasing the stiffeners. At the same time, when installing the reducer, it should be ensured that the reducer is installed in the correct position and the foundation levelness 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 abrupt change, etc. These disturbing factors can cause the reducer to shake.
The solution to this problem is to take corresponding vibration reduction and anti-interference measures, such as installing shock absorbers between the motor and the reducer, and smoothly controlling the load. 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.
To sum up, there are many reasons for the jitter of the hard tooth surface gear reducer during operation, which needs to be analyzed and dealt with according to the specific situation. For different reasons, taking corresponding measures can improve the stability and reliability of the reducer and ensure the normal operation of the equipment. Gear reducer
