As a core component of the transmission system, the sealing performance of a gearbox directly affects lubrication effectiveness, contaminant intrusion, and equipment service life. If the seal fails, it may lead to lubricating oil leakage and the entry of external impurities, which in turn can cause ... Read More

The discontinuity of metal materials refers to the non-uniformity and abrupt changes in their internal structure, composition, or properties. In failure analysis cases, it is found that many failures are caused by the discontinuity of materials. The discontinuity of structures is mainly reflected in ... Read More
