Roots Blower Gear Reducer Damage Solution
Roots BlowerIn the process of using the machine gear reducer is damaged, so what are the reasons and solutions for this situation? Roots blower small editor to take you to understand.
1. The center of the Roots blower gear shaft is installed incorrectly, the reducer large gear shaft and blower shaft, reducer pinion and motor shaft is not concentric, or the two gears are installed in a non-parallel, will cause vibration of the reducer. If the deviation of the different centrifuges is large, it will make the gear operation unstable and produce violent vibration, moreover, it will make the tooth surface subject to serious wear. If the two gears are not parallel, gear operation, there will be a local “crappy” parts, and when serious, the teeth will break. When the above phenomenon is found, the parallelism of the two gears and the contact surface of the inspection, and should be carried out to find the coupling level and find the right.
2. The gap between the various parts of the Roots blower gear is incorrect, which includes the bearing gap, the side gap of the two gear meshing and the top in addition. These clearances must be adjusted to the required range. The correct clearance adjustment will make the gear in the operation of smooth, no noise; if the clearance is too large, it will occur gear shaking, bumping, especially in the starting, this phenomenon is particularly obvious; clearance is too small will make the operation of the sound noise, bearing temperature is high, the operation is not stable.
3. Poor lubrication is also one of the reasons for premature gear wear. The amount of lubricant is too low, the gears do not throw on the oil, will wear the tooth surface, noise; Conversely, the amount of lubricant is too much, it will make the bearing temperature increase. If the impurities in the lubricating oil, especially hard substances such as iron filings, etc., it will happen to study the tooth surface or make the gear break and other phenomena. Therefore, the lubricating oil should be kept clean and changed regularly.
4. Roots blower tooth shaft casting or forging quality is not good, improper heat treatment, processing quality is rough, the blower is not stable enough in operation, etc., will reduce the gear strength, or make the gear premature wear.
