The function of the Universal Shaft Assembly is to convert planetary motion into fixed constant rotation of the drive shaft, to transmit torque and speed from motor on the drive shaft, and to the bit. Cardan shaft mostly uses flat shaft, but some are flexible shafts. Out flat type shaft used on out downhole motor is made by linear cutting technology. So the cut has high parallelism, roughness can reach 6.3 and it doesn't damage metal chemical composition. Thus, is has a longer running life and less mechanical loss.
Downhole motor shall be disassembled as quickly as possible after use to examine cardan shaft. If it is found out that wear degree is over maintenance standard, relevant consumable components shall be changed promptly. If not, downhole motor can not be running normally due to overrun of the cardan shaft.
