couplings can either be rigid or flexible. Rigid couplings are for well-constrained systems where the two shafts are not likely to get out of perfect axial alignment. Rigid couplings include ...

Flexible couplings couple or connect rotating members such as motors and drive shafts while allowing misalignment in either angular or parallel offset orientation. Sliding blocks are slotted or jawed ...

Figure 5.63: Typical benefits of flexible shafts. When mounting a motor to drive a pump, a gearbox, or any device with self-contained bearings, a conventional coupling can absorb only small amounts of ...
