Offset

Offset fixtures and software

Machines with offset drives are often thought of as insensitive to angular errors between driving and driven shaft. However, they cannot absorb angular misalignment between the shafts, hence our kit the Offset Fixtures. Conventional alignment methods do not provide the required level of accuracy.

How to use the Offset ?

Despite popular opinion, it is necessary to eliminate angular misalignment of shafts connected by an offset, or cardan, shaft.. This video from Acoem shows how to use the cardan brackets and software to accurately measure and correct the angular misalignment that can cause problems for offset shaft driven machinery.

Why align cardan shafts?

Cardan shafts with angular misalignment typically cause the driven shaft to rotate unevenly during operation, which results in increased vibration. In other words, it is just as important to align cardan shafts as regular shafts. Why is that?

A vital part in drives for machines, where breakage of cardan shafts causes downtime
Badly aligned cardan shafts set limitation in production capacity and product quality
Stands for a considerable cost when repairs are needed or a breakdown occurs
Badly aligned cardan shafts reduce lifetime in gearboxes and motors
The breakdown of a cardan shaft in running condition could be extremely dangerous.

Use the NXA Pro with the Offset Fixture kit and you can precision align any offset mounted machine as fast as you align any other shafts. The Offset Fixture kit consists of both software and fixtures.

Our case studies

Align any offset mounted machine as fast as you align any other shaft !

Machines with offset drives are often thought of as insensitive to angular errors between driving and driven shaft. Vibration analyses and experiences from paper industry professionals have proved that this is not the case. Conventional alignment methods cannot provide the needed level of accuracy. Using the Acoem NXA Pro together with the Acoem Offset NXA Pro expansion it, you can precision align any offset mounted machine as fast as you align any other shafts.
