    Abstract: A driveshaft transmission assembly may include a catch assembly. The catch assembly may prevent the loss of certain driveshaft transmission assembly components downhole in the event of a failure of the driveshaft transmission due to dynamic loads produced during operation of a drilling system. The catch assembly may be coupled to a first radial bearing assembly using locking devices. The driveshaft transmission assembly may also include a second radial bearing assembly interlockably coupled to a thrust bearing and a bearing housing.

    Abstract: According to one embodiment, the disclosure relates to a roller cone drill bit including a bit body having at least one support arm extending therefrom, a cone assembly containing bearings or retaining balls and rotatably mounted on a journal extending from each support arm, a lubricant reservoir disposed in each support arm, a lubricant chamber disposed in each support arm and fluidly coupled to the bearings or retaining balls, a bore disposed in each support arm to communicate lubricant between the lubricant reservoir and the lubricant chamber, and a pressure release mechanism disposed within the bore. The pressure release mechanism may be operable to relieve lubricant from the lubricant reservoir into the lubricant chamber when lubricant pressure within the lubricant reservoir exceeds pressure of the lubricant in the lubricant chamber. According to another embodiment, the disclosure relates to methods of relieving lubricant in such a bit.
