Coupling

This coupling is particularly useful for automatically coupling, aligning and phasing two shafts, where the coupling location is not easily viewable.

The coupling is used, for example, to releasably couple input shaft 10 to output shaft 11. Shaft 11 carries plug 12, having a pair of 180 degrees disposed phasing slots 13, and an annular, tapered aligning surface 14. Plug 12 fits into a socket member 15 carried by shaft 10. This plug pivotally mounts a pair of 180 degrees disposed phasing pawls 16, one of which is shown in exploded view. These two pawls are biased to the position shown by garter spring 17.

When plug 12 is placed within socket 15, aligning surface 14 aids in the insertion. Once inserted with proper axial alignment, the two shafts will turn relative to each other until pawls 16 drop into slots 13. Subsequently shafts 10 and 11 turn in unison and with proper phasing.
