Abstract: A downhole motor for directional drilling includes a driveshaft assembly including a driveshaft housing and a driveshaft rotatably disposed within the driveshaft housing. In addition, the downhole motor includes a bearing assembly including a bearing housing and a bearing mandrel rotatably disposed within the bearing housing. The bearing mandrel has a first end directly connected to the driveshaft with a universal joint and a second end coupled to a drill bit. Further, the downhole motor includes an adjustment mandrel configured to adjust an acute deflection angle ? between the central axis of the bearing housing and the central axis of the driveshaft housing. The adjustment mandrel has a central axis coaxially aligned with the bearing housing, a first end coupled to the driveshaft housing, and a second end coupled to the bearing housing.

Abstract: A downhole motor includes a bearing assembly having a mandrel rotatable within a cylindrical housing, with the mandrel co-rotatably engaging the rotor of a concentric rotary drive system incorporating an arrangement of housing-mounted gates pivotably deflectable by rotor lobes as the rotor rotates in response to fluid flow through an annular space between the rotor and the housing, building up pressure in longitudinal chambers formed between adjacent gates and lobes and thus inducing rotation of the mandrel. Preferably, the drive system is coupled directly to the bearing assembly, without need for a connecting driveshaft, and with the housing incorporating a bent sub positioned above the drive section. Alternatively, a bent sub may be positioned below the drive system in conjunction with the use of a driveshaft to connect the drive system to the bearing section, in order to position the bend as close as possible to the bit.
