titleOfInvention |
Plain and thrust bearing device |
abstract |
A device for reducing friction between surface planes sliding against each other in axial thrust bearings between the shaft end and roller in rotary roller bits and rollers for rock and earth boring, especially at full size tunnel driving. A friction reducing groove is arranged eccentrically in relation to the axes of the shaft end and the roller in at least one of the surface planes sliding against each other. Said groove is filled with material having a friction reducing and/or lubricating effect. |
