Extended Wear Lifetime Calculation for Grease Lubricated Gears in Consideration of Surface Hardness and Roughness [PDF]

MATEC Web of Conferences, 2022
Greases have a variety of advantages when special operating conditions apply for gear lubrication, e. g. improved properties against continuous (or slow speed) wear.

Machine Learning Based Surrogate Models for the Thermal Behavior of Multi-Plate Clutches

Applied System Innovation, 2022
Multi-plate clutches play safety-critical roles in many applications. For this reason, correct functioning and safe operation are essential. Spontaneous damages are particularly critical because the failure of the clutch can lead to a failure of the ...

Analysis of the Thermo-Mechanical Behavior of a Multi-Plate Clutch during Transient Operating Conditions Using the FE Method

Lubricants, 2022
Failures of multi-plate clutches must be reliably excluded due to safety-critical functionalities in the drive train. The main reason for failures of multi-plate clutches due to long-term and spontaneous damage is thermal damage.

Comparison of Various Wet-Running Multi-Plate Clutches with Paper Friction Lining with Regard to Spontaneous Damage Behavior

Tribology in Industry, 2021
Wet-running multi-plate clutches fulfill a major safety-relevant role in drive trains and, as a result, damage to and failure of the clutch system must be strictly avoided, especially spontaneous damage.

Load Capacity Comparison of Different Wet Multi-Plate Clutches with Sinter Friction Lining with Regard to Spontaneous Damage Behavior

Tribology in Industry, 2022
Wet multi-plate clutches are safety-critical components of drive trains. Failure and damage must therefore be strongly avoided. In contrast to long-term damage, spontaneous damage and failures are difficult to predict.

Running-In Behavior of Wet Multi-plate Clutches: Introduction of a New Test Method for Investigation and Characterization

Chinese Journal of Mechanical Engineering, 2020
Wet multi-plate clutches are relevant components of modern drivetrain applications, not only in terms of function but also safety and comfort. Especially at the beginning of their lifetime, distinct changes of the friction behavior may occur and make the
