ABSTRACT:
Method for determining the extent to which noise occurs in a rotating roller bearing of a specific type lubricated with a specific lubricant, whereby an amount of the lubricant to be examined is applied to a roller bearing of the type mentioned, the inner race of the roller bearing is rotated for some time by means of a rotatable rod inserted in the inner race of the roller bearing until it interacts with it, and the vibrations occurring in the bearing are recorded by means of a vibration recorder which is in contact with the immobile outer race of the bearing, and a peak value is determined, following which these steps of the test cycle are repeated several times with new amounts of the same lubricant, characterized by the fact that a single roller bearing of the type specified is used in which every time, at the start of the steps of the test cycle, an amount of the lubricant to be tested is applied under pressure, whereby the amount of lubricant in the roller bearing which has been examined in a previous cycle is driven out under negative gas pressure before a new amount of lubricant is inserted into the bearing.
