Abstract
A self-aligning coupler 100 for power transmission between misaligned and non-collinear driving shaft and driven shaft is disclosed. The self-aligning coupler 100 has at least a first extreme position, an intermediate position and a third extreme position. The first coupler 104 is connected to the second coupler 112 by a tie rod 108. One end of the first coupler 104 includes a central hole 320 for receiving a driving shaft and another end of the first coupler 104 includes a first arcuate opening 324 for receiving the tie rod 108. One end of the second coupler has a central hole 326 including a driving shaft and another end of the second coupler 112 has a second arcuate opening 328. The tie rod 108 has three degrees of freedom of movement.
