<p>The flexible shaft coupling comprises first and second rotary hubs (5,5') securable by keys (8,8') to ends of driving (9) and driven (9') shafts, respectively. Central circular portions of abutting pairs of flexible, dished metal foils are secured to the hubs by bolts (7,7'). Cylindrical rims of the foils are secured to the opposite ends of a surrounding torque transmission sleeve (10) by further bolts. The foils of each pair are formed with obtuse scalene triangular slots (2,2') which incline in opposite directions and are tangential to the central circular portion of that foil. The slots of the respective foils overlap one another. Drive can be transmitted when the axes of the shafts are parallel but spaced from one another, are relatively inclined, and when they are axially relatively movable. The slotted formation of the foils allows high torque to be transmitted without significant torsional distortion.</p> |
