Abstract: A rotor catch system includes a catch stem having a proximal end coupled to a rotor of a mud motor system and a distal end positioned within a sub housing of a drill string, a catch feature having a top portion and a spindle portion extending from the top portion and coupled to the distal end of the catch stem, a housing catch feature extending radially inward from an inner surface of the sub housing, and a catch bushing positioned between the top portion of the catch feature and the housing catch feature. The housing catch feature restrains axial movement of the catch bushing in the active catch state via contact between the catch bushing and the housing catch feature, and the catch bushing restrains axial movement of the catch feature in the active catch state via contact between the catch feature and the catch bushing.

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: A clamping assembly may include a split-ring device and bearing for coupling to a driveshaft. The split-ring device may comprise split-ring shells having protrusions on an interior radial surface for positioning in grooves adjacent to radial protrusions on the driveshaft. In some aspects, the split-ring shells may include tabs corresponding to cavities on a first bearing for coupling the split-ring shell to the first bearing. In other aspects, the split-ring shells may be sized to create one or more gaps when positioned on the driveshaft. The first bearing may include one or more corresponding tabs for positioning in the one or more gaps created by the split-ring shells. A second bearing may be threadably coupled to the first bearing to suppress the axial and rotational movement of the clamping assembly separate from the driveshaft.
