Filed: 2003-09-26
Abstract: For an external diameter (DEN) of the connecting element, an internal diameter (DIN) of the connecting element and a diameter (DHN) from which the transmission shoulder leaves, the following ratios are maintained: DHN/DEN 0.6-0.98; DIN/DEN 0.15-0.90; DIN/DHT 0.25-0.92.  Long drive train assembly made of a number of hollow pumping shafts (3a, 3b) with an axis, assembled together at between a drive head at the surface of an oil well and a rotating pump at the bottom of the well. One end of each pumping shaft has an internal female threaded surface coupled to an external male threaded surface on a connecting element (2). The threads are tapered, un-symmetrical, but both have a different diametric conicity. The free ends of the pumping shafts also have an annular shoulder transmitting couple on a connecting element. Each differential thread has a thread in the shape of a non-symmetrical trapezium. The thread is complete on the connecting element and incomplete on the first end of the hollow shaft. The transmission shoulder makes an angle of 75-90 degrees, preferably 83 degrees with the axis of the train. The ratio between the external diameter of the connecting element (DEVU) and the external diameter of the hollow shaft (DEV) is held so that (DEVU/DEV) =1-1.5. The ratio between the diameter of the shoulder position (DHT) and the internal diameter of the hollow shaft at the free end of the thread (DIFR) is held so that (DIFR/DHT) = 1-1.1. The connecting elements are nipples or integrated with the second end of each hollow shaft with the same proportions. The threads are Modified Buttress threads with 8 threads per 2.54 cm. The male threads have a conicity of 0.0976  cm per cm diameter and the female threads have a conicity of 0.1 cm per cm diameter.  An Independent claim is included for a hollow pumping shaft as described above and a connecting element for coupling such shaft sections.
