We are sure to encounter various factors when using the gearbox. How to judge the difficulty of the speed of the drive shaft in the use of the gearbox?
Gearboxes typically have a multi-stage configuration with different speed ratios for each stage of transmission. Under normal circumstances, the gearbox manufacturer only provides the total gear ratio of the gears. It does not provide the gear ratio of each stage and the number of gear teeth in detail. This makes it difficult to accurately determine the bearing failure of the intermediate drive shaft.
Determining the rotational speed of each drive shaft is the key to correctly analyzing and judging the bearing failure, because the bearing fault characteristic frequency is related to the bearing structure size and the bearing speed. The structural dimensions of the bearing (roller diameter, roller diameter, contact angle) and the number of bearing rollers are internal factors, which are determined by the bearing manufacturer. The second speed is an external factor, and the same bearing is at different speeds. Upper, the fault characteristic frequency of the bearing is different.http://www.delinggearbox.com/
