The gear is a part of the biomass pellet machine. It is an indispensable core part of the machine and equipment, so its maintenance is very important. Next, Shandong Kingoro pellet machine manufacturer will teach people how to maintain the gear to be more effective. To maintain it.
Gears vary according to their functions, and many quality problems arise. Therefore, better maintenance can reasonably and effectively prevent gears from ineffective forms such as pitting, damage, gluing, and plastic disengagement on the tooth surface.
If the gear is fully exposed during the operation of the gear, it is easy to fall into the sand and impurities, and good lubrication cannot be ensured. The gear is easy to be damaged and the shape of the tooth profile is damaged, resulting in shock, vibration and noise. It may be due to the thinning of the tooth thickness. Broken gear teeth.
1. Improving the sealing and lubrication conditions, replacing waste oil, adding anti-friction additives to the oil, ensuring the cleanliness of the oil, enhancing the hardness of the tooth surface, etc., can all enhance the ability to engage in abrasive damage.
2. The use of sprocket: When using machinery, the sprocket should avoid using even-numbered sprocket as much as possible. Such sprocket will accelerate the damage of the chain. For example, if a certain tooth profile is not accurate, the even-numbered teeth will wear off certain links of the chain, while the odd-numbered teeth will wear in series, which will damage evenly, ensuring the regular life of the chain.
Improper use and maintenance. For example, when new machinery and equipment are put into production, the gear drive of the biomass pelletizer has a running-in period. During the running-in period, there are deviations due to manufacturing and assembly, including surface unevenness factors, and meshing wheels. In fact, only the tooth surfaces are in contact with the teeth. Therefore, during the initial operation, these initial contact areas will be damaged first due to the relatively large force per unit area. However, when the gears are running for a period of time, the actual contact area between the meshing tooth surfaces expands, the force per unit area is relatively small, and the lubrication conditions are further improved. Therefore, this kind of initial tooth surface damage will gradually Stable and disappear.
If the hard tooth surface is rough, the running-in time is longer; the harder tooth surface is smooth and the running-in time is short. Therefore, the harder tooth surface is designed to have a smaller roughness. Practical experience has proved that the better the gears run in, the more matched the meshing conditions are.
In order to prevent abrasive damage during the running-in operation, the lubricating oil should be replaced irregularly. If working at full load at high speed during the running-in period, damage will be aggravated, resulting in wear debris, resulting in damage to abrasive particles. Damage to the tooth surface will result in changes in the shape of the tooth profile and thinning of the tooth thickness. In serious cases, the gear teeth can break.
