kiertesliittymiä

Kiertesliittymiä is a Finnish term used in technical contexts to describe interfaces or connections that allow rotation or twisting between parts. The plural form kiertesliittymiä comes from kierto (rotation, twist) and liittymä (connection, interface).

Usage: The term appears in mechanical engineering, robotics, piping, and structural design when components must move relative to one another or tolerate misalignment while maintaining a functional link.

Definition: A kiertesliittymä may be a joint, coupling, or interface that permits limited torsional movement or twist while transmitting force or signal. Such connections help reduce stress from torque, accommodate misalignment, and damp torsional vibrations.

Design considerations: Designers evaluate torque transmission, torsional stiffness, backlash, fatigue life, lubrication, sealing, and maintenance needs. Materials are chosen for stiffness-to-weight and wear resistance; geometric clearances determine allowable twist.

Examples and scope: In drive systems, flexible couplings and certain drive-shaft configurations can be described as kiertesliittymiä. In process piping, flexible connectors that tolerate rotation and twisting are cited similarly. The term is mostly used in Finnish-language sources or discussions focusing on rotational interfaces.

Related concepts include torsional joints, universal joints, and flexible couplings, which address similar needs for transmitting motion or signals while accommodating twisting and misalignment.
