Abstract
673,185. Rotary borehole drilling. ENGINEERING DEVELOPMENT CO., lnc. Jan. 19, 1950. No. 1498/50. Class 85. [Also in Group XXVI] A rotary well drilling assembly, wherein the bit is rotated by a turbine operated by the drilling mud, is assembled in the following manner : about the part of the rotor shaft, to the lower end of which is connected the bit, is concentrically positioned by a bearing 26 interconnected sleeves 24, 25 and a stator retaining ring 32, projections 92 on which co-operate with a shoulder 12 to axially position the sleeves, stator and casing relative to the rotor shaft. The rotor and stator rings are now added alternately, the rotor rings being keyed to the shaft whilst dovetail joints on the stator rings prevent transverse or circumferential movement thereof. Projections 97 on a stator ring 39 are positioned between annular ridges on rotor retaining rings which are secured in position by a nut 84. Interlocked to the stator retaining ring is a sleeve part and a bearing housing 42. Over this assembly is slid a sleeve 60 which is connected to the sleeves 28 by keys 30 and the upper end of the bearing housing is secured relative to this sleeve by a spider nut 122 threaded within the sleeve, engaging a nut 52 sealing the end of the housing 42. This sleeve 60 is secured onto the end of the drill pipe so that mud flows down the pipe through the annular passage formed between the housing 42 and the sleeve 60 and into the sleeve 40 by passages at the joint between said sleeve and the housing, thence through the stator and rotor rings to escape through parts 8 and a passage 6 in the rotor shaft. The upper bearing is completely closed at the top, and at the bottom additional protection to that provided by the chevron type packet 98 is given by forming an annular chamber 48 in the housing 42 below the bearing assembly and filling this chamber with grease so that any mud penetrating into the housing must first force the grease from this chamber into the ball races 104, 106 before it can penetrate the races between which are provided spaces 112.
