Universal Coupling Assembly, Cardan Shaft Assembly, Downhole Motor Consumable Parts

The function of universal coupling is to convert planetary motion into fixed constant rotation of drive shaft, to transmit torque and speed from motor on the drive shaft, and to the bit. Universal coupling mostly use flat shaft, but some are flexible shafts. Our flat type shaft used on our 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, it has longer running life and less mechanical loss.

Downhole motor shall be disassembled as quickly as possible after use to examine the universal coupling. If it is found out that wear degree is over maintenance standard, relevant consumable components shall be changed promptly. If it is not, downhole mud motor cannot be running normally due to over run time of universal coupling.

For conventional universal coupling, more wear resistant and more environmentally friendly surface hardening treatment method is adopted, and the working life is greatly improved. Through our improvement on material, process and structure, its average working life achieves more than 400 hours for 6 3/4’’ downhole mud motor.

A new universal coupling system has been developed, adopting sealing structure. Both drilling mud lubrication and lubricating oil lubrication are available. The ball contact drive system with larger contact area brings more stable driving, reduces impact abrasion, and greatly improves working life. It is with large rotation angle, and 180° spherical rotation could be realized.
