The hard tooth surface gear reducer is a very precise reducer equipment in transmission products. It is an essential component in the entire transmission system and plays a very important role.If the hard tooth surface gear reducer works for a long time or under overload conditions, the wear of the hard tooth surface and gears will inevitably accelerate, thus affecting the overall use and production efficiency.The following are common faults of hard tooth surface gear reducers:
1. Reasons for excessive tooth surface loss of hard-tooth surface reducer:
1. The gear tooth surface of the reducer does not meet the assembly requirements during processing, or the installation process is not rigorous enough, causing the meshing gap between the gears to be too large or improper;
2. Lack of lubricating oil; the lubricating oil does not meet the use requirements of the hard-tooth surface reducer. The oil viscosity is low and the lubrication performance is poor.The oil level is too high and the oil temperature rises, which reduces the viscosity of the lubricating oil, destroys the lubrication performance, reduces the working thickness of the oil film, and causes excessive friction between gears to aggravate gear wear;
3. Excessive use of hard-tooth surface reducer and lack of regular maintenance.
2. Causes of gear cracks and tooth tip breakage:
1. When the gear is subjected to torque and lateral load during operation, cracks will form and loosen in weak areas;
2. Due to braking and other reasons, the steady load between gears is converted into an impact load, which will have a certain impact on the occurrence and development of cracks;
3. When the gear is loaded on the motor shaft, some operators blindly increase the heating temperature of the gear, making the loading amount of the gear too large. As a result, after the gear cools down, the radial force of the motor shaft on the inner diameter of the gear increases, in the radial direction. Under the combined action of force and torque, the low-strength parts of the gear tooth roots are prone to cracks;
4. If the gear teeth of the hard-tooth surface reducer are broken or otherwise damaged, new parts can only be reprocessed;
5. If the shaft surface, shaft hole, keyway and other places of the hard-tooth surface reducer are worn, electroplating can be used to restore the accuracy of the parts.
The above are the problems that may occur during the installation and use of hard-tooth surface reducers.
When adding lubricating oil to the hard-tooth surface reducer, you should also pay attention to several points:
1. It is forbidden to mix different lubricating oils with each other. It is best to add lubricating oil that conforms to the hard tooth surface reducer;
2. Check the oil level and cut off the power supply to prevent electric shock!Wait for the reducer to cool down!Check whether the oil is full;
Cut off the power to prevent electric shock!Wait for the reducer to cool down!Take an oil sample.Check the viscosity index of the oil.If the engine oil is obviously cloudy, it is recommended to change it as soon as possible.
Again, I would like to remind everyone that the hard-tooth surface reducer should be maintained regularly to avoid unnecessary losses.
