Rope coupling able to stop unwanted force generation. It should be noted that rope coupling is designed on the fact that sugar mill couplings are essentially unidirectional and require only modest misalignment ability of some 60 mm axial displacement and less than 1deg of angular misalignment.

There are two components of misalignment—angular and offset. Offset misalignment, sometimes referred to as parallel misalignment, is the distance between the shaft centers of rotation measured at the plane of power transmission. This is typically measured at the coupling center. The units for this measurement are mils (where 1 mil …
Roller chain couplings are extremely simple but provide a compact and flexible coupling that is suitable for an extremely wide range of applications. Because of the design, the torque is distributed throughout the roller chain and sprocket teeth, so there is an even amount of torque distributed throughout the coupler when in motion.

Positioned on the low-speed, high-torque shaft between the gearbox and pinion drive, the gear coupling rotates at approximately 10 RPM. The goal was to ensure that the new coupling was capable of transmitting the new, higher torques. The mill contacted several coupling manufacturers, including the original coupling OEM.

This work evaluates the effects of pitch, yaw, and roll angular misalignments for a butt coupling scheme involving the optical coupling between a single-mode fiber and a laser diode. It is demonstrated that the coupling efficiency and misalignment tolerance are more sensitive to tilt, i.e., pitch and yaw angular misalignments than lateral ones.
