ABSTRACT:
A flexible drive shaft for connection to the rotor of a progressive cavity pump or motor, in which the drive shaft 7, provided with a coating 26, is formed of titanium or similar metal. A relatively inexpensive metal flanged head portion is fastened, e.g. by adhesive, to an end portion 12, of the drive shaft, and is bolted to the rotor 10. The structure enables a relatively shorter drive shaft to be used which is capable of transmitting heavy torque.
