  • Lubrication System and Method for Kinematic Linkage
    Publication number: 20260062889
    Abstract: A machine can include one or more kinematic linkages having pivot joints that are pivotally articulated by associated hydraulic cylinders. To determine the total joint forces applied to the pivot joints, pressure data is obtained from the hydraulic cylinders and converted to cylinder forces. The cylinder forces are analyzed to determine the total joint forces, and the total joint forces are used to calculate wear severity with respect to the pivot joints. The wear severity can be compared to a lubrication trigger value to determine whether to lubricate the pivot joints.
