Rotary power transmission assembly
Abstract
Abstract THE ROTARY POWER TRANSMISSION ASSEMBLY COMPRISES TWO SPACED APPROXIMATELY RIGHT-ANGLED GEAR DRIVES IN WHICH ONE OF THE DRIVES IN CONSTRUCTED AND ARRANGED TO DIVIDE THE INPUT TORQUE INTO TWO TORQUES AND THE OTHER DRIVE OF SIMILAR CONSTRUCTION, BUT ARRANGED TO COMBINE THE TWO TORQUES INTO A SINGLE OUTPUT TORQUE. THE TWO TORQUES ARE TRANSMITTED FROM ONE RIGHT-ANGLED GEAR DRIVE TO THE OTHER BY TWO SHAFTS DISPOSED ONE WITHIN THE OTHER TO PROVIDE A RELATIVELY COMPACT ASSEMBLY. A TORSIONALLY FLEXIBLE COUPLING IS ARRANGED TO COACT WITH THE SHAFT OF GREATEST RIGIDITY TO PROVIDE SUCH SHAFT WITH AN EFFECTIVE TORSIONAL DEFLECTION RATE SUBSTANTIALLY EQUAL TO THE TORSIONAL DEFLECTION RATE OF THE LESS RIGID SHAFT. A VIBRATION DAMPENING MEANS IS PROVIDED TO COACT WITH ONE OR MORE BEARINGS LOCATED CLOSEST TO THE POINT OF VIBRATION ANTINODE TO MINIMIZE RESONANT VIBRATIONS. THE TORSIONALLY FLEXIBLE COUPLING AND THE VIBRATION DAMPENING MEANS CONTRIBUTING TO PROVIDING EQUAL LOADING ON THE TEETH OF THE MESHING GEARS OF THE RIGHTANGLED GEAR DRIVES AND THE MINIMIZATION OF FRETTING CORROSION AND FAILURE OF THE GEAR TEETH.
