How to determine the service life of the bearings in the TY200-35.5-22KW hard-tooth surface gear reducer.

To determine the bearing service life of TY200-35.5-22KW hard tooth gear reducer, it is necessary to comprehensively consider multiple factors and apply corresponding calculation methods and empirical data. The following is a specific introduction:

Determination of Bearing Service Life

Basic rated life calculation: According to ISO 281 standard, the basic rated life of a bearing (unit: million revolutions per minute) refers to the expected achievable or exceeded life of 90% of a group of the same bearing before surface material fatigue occurs,

Consider correction factors: In practical applications, correction factors such as temperature, lubrication, and load properties also need to be considered. For example, the temperature coefficient can affect the bearing life, and the higher the operating temperature, the shorter the bearing life; There are also reliability coefficients, material improvement coefficients, and operating condition coefficients, which can be used to correct the basic rated life and more accurately estimate the service life of bearings under actual working conditions.

Monitoring and experience judgment: In addition to theoretical calculations, the service life of bearings can also be determined by regularly monitoring their working status, such as measuring temperature, vibration, noise, and other indicators, combined with the engineer's experience. If an abnormal increase in bearing temperature, intensified vibration, or increased noise is detected, it may indicate that the bearing is about to fail and needs to be replaced in a timely manner.
