linkousnopeudet

Linkousnopeudet, literally “slip speeds” in Finnish, is a term used in engineering and tribology to describe the velocity at which relative motion occurs between two contacting surfaces during slipping. It denotes the instantaneous speed difference at the interface when static friction transitions to kinetic friction or when ongoing slip exists in a moving contact pair. In practice, linkousnopeudet characterize how quickly surfaces slide past each other under load, temperature, and lubrication conditions, and they are related to, but distinct from, the overall motion of the machinery.

The concept is applied across domains such as automotive drivetrains, conveyor systems, belt and chain drives, braking systems, and rotor or bearing assemblies. In these contexts, controlling or predicting linkousnopeudet helps assess wear, heat generation, vibration, and noise, as well as system stability. The term is commonly used alongside related ideas such as slip ratio and friction coefficients to describe the dynamic state of contact interfaces.

Measurement and calculation of linkousnopeudet typically involve determining the relative surface velocities at the contact, which can be expressed as v_slip = |v1 − v2|, where v1 and v2 are the surface velocities of the interacting components. It can also be presented as a slip ratio, s = (v1 − v2)/v1, or in terms of linear belt or rotor speeds. Accurate assessment relies on sensors, motion capture, or indirect inference from torque and speed data under known geometries.
