Abstract
A driveshaft transmission assembly may include a catch assembly having a catch mechanism and pressure plugs. 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 in a drilling system. The catch mechanism may be coupled to a radial bearing assembly by the pressure plugs. The pressure plugs may secure the catch mechanism to the radial bearing assembly during operation of the driveshaft transmission assembly using a normal force created by a pressure differential between downhole pressure external to the catch mechanism and ambient pressure sealed in the recesses of the radial bearing assembly.
