Duty Cycle Analysis as a service

Clever design of cardan shafts!

Every calculation model is only as good as the input. If only there was a clever way to capture real world duty cycles to avoid having shafts under / oversized based on estimations. The measurement technology of the Walterscheid Powertrain Group makes it possible!

Through integrating sensor functionality into the driveshaft, we make duty cycle measurement under real conditions accessible to our customers. This service is an important enhancement to our existing capabilities of life estimation; especially in marginal applications.

Agricultural OEMs rely on Walterscheid
to acquire real duty cycle under end user operation

Lack of information about actual duty cycle under real driving conditions is an issue often faced by our customers. Data that is only an estimation could lead to shaft being over-/undersized. In this particular case, the customer requested for a review of the drivetrain design for an existing tractor platform using a duty cycle obtained under real conditions.
