A paper mill recently changed over from a belt drive take off to an individual 150 HP DC motor. To complicate matters, space was limited and the mounting resulted in fairly significant misalignment.
As a result, the original gear coupling failed on a regular basis. The mill then went to a grid coupling, but unfortunately it also failed.
Given the torque and misalignment required in this envelope, there were not a lot of options. We were able to come up with a custom universal shaft assembly which significantly increased the coupling’s torque capacity.
Additionally, we made up the assembly with custom flanges that matched the existing gear and grid coupling rigid hubs. This made the replacement a simple drop-in operation.
Let us know if you have a tough application.
