![]() ![]() ![]() This assures that the coupling will fail before something more costly breaks elsewhere along the drive train. One is to provide a break point between driving and driven shafts that will act as a fuse if a severe torque overload occurs. In certain cases, flexible couplings are selected for other protective functions as well. If not properly compensated, minor shaft misalignment can result in unnecessary wear and premature replacement of other system components. Even with very good initial shaft alignment there is often a tendency for the coupled equipment to “drift” from its initial position, thereby causing further misalignment of the shafts. The coupling will, to varying degrees, minimize the effect of misaligned shafts. Such compensation is vital because perfect alignment of two shafts is extremely difficult and rarely attained. Belt, chain, gear and clutch drives also transmit power from one shaft to another, but not necessarily at the same RPM and not with the shafts in approximately the same line. The second is to compensate for minor amounts of misalignment and random movement between the two shafts. The first is to transmit power (torque) from one shaft to the other, causing both to rotate in unison, at the same RPM. A flexible coupling connects two shafts, end-to-end in the same line, for two main purposes. ![]()
