EXPERIMENTAL STUDY OF BEARING BOXES FRICTION DEPENDING ON LOAD SPEED AND OIL TEMPERATURE

?The subjects of this paper are the bearing boxes of a testing rig for chain drives. Friction in transmission without bearings is calculated by subtracting the bearing friction from the global friction. This is why it is of maximal importance for the correct evaluation of experimental measurements on the rig to have accurate data on the friction on bearing boxes. Bearing boxes friction is measured depending on rotational speed, load and lubricating oil temperature.
