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.

Purpose In industrial applications, couplings are widely utilised, primarily to connect prime movers to process machines. However, coupling must contend with various induced moments, additional load toque, stress under vibrations, and misalignment during operation. One of the most significant challenges it encounters is shaft misalignment. …

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. Fig.3 New sugar mill drive coupling [1].

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 …
