Tooth surface gluing is a phenomenon. When the gear continues to run, due to the relative sliding of the two gears, grooves are torn on the gear surface. This phenomenon is called tooth surface gluing, or gluing for short.
In high speed and heavy load gear transmission, the oil film of lubricating oil is often destroyed due to the temperature rise, and the contact tooth surface has a very high instantaneous temperature. At the same time, under a very high pressure, the metal at the contact point of the tooth surface is locally bonded together.
Severe wear will occur after tooth surface gluing. In order to prevent scuffing, lubricating oil with higher viscosity or better scuffing resistance can be used to improve the hardness of tooth surface and reduce the Surface roughness And other measures. [1]
