ABSTRACT:
A downhole drilling apparatus which includes a drive train having a downhole motor device and a coupling for permitting bending of the drive shaft to accommodate directional drilling. The coupling includes two distinct portions. The first portion transmits torque only and the second portion transmits thrust only. Thus, the coupling transmits torque and thrust through different portions. This makes it possible to optimize the coupling design to allow bending while still being able to transmit the loads experienced downhole. The downhole motor may be a progressive cavity device, a turbine-type downhole motor or another type of downhole motor such as an electric motor.
