Patent search and review on roller-bit bearings seals and lubrication systems. [State-of-the-art]

Over 300 patents on bit design were reviewed, and the more important ones were abstracted. These patents were divided into three groups dealing with roller bit bearings, seals, and lubrication systems. Review of these patents helps identify the problems encountered by previous bit designers and establishes the current state-of-the-art of roller bit design. This report can be used as a reference for designing improved bits both for the petroleum and the geothermal industries.
