The cause of transmission gear wear is

2019-12-12

Transmission gears frequently operate under conditions of high rotational speed, heavy load, and continuous fluctuations in both speed and load. In addition to normal wear, gear damage can also result from poor lubricant quality, inadequate lubrication, improper driving practices, or incorrect meshing alignment during assembly—any of which can lead to gear impact, poor tooth engagement, and jerky vehicle acceleration, all of which accelerate gear wear and damage. Furthermore, wear and deformation in other gear components or related parts—such as spline slots in gear bores, bearings, and splined shafts—as well as misalignment in clutch or drive-shaft assembly and certain manufacturing defects (e.g., non-uniform carburized layers or gear warping) can likewise hasten gear wear.
