摘要

The gear has a lubricant and an evaporation tube (5) is heat conductively connected with the lubricant in such a way that the temperature of the evaporation tube corresponds to the temperature of the lubricant. The amount of evaporated fluid (6) in the evaporation tube is the measure of lubricant deterioration. The quantity is a clearly assigned readable quantity of the lubricant deterioration. Independent claims are also included for the following: (1) an evaporation tube (2) an application of the evaporation tube for determining the lubricant deterioration.
