kierresäätö

Kierresäätö, often translated as "coiled spring adjustment" or "spiral adjustment," is a Finnish term referring to a method of adjusting the tension of a coiled spring. This technique is commonly employed in various mechanical devices where precise spring force regulation is necessary. The core principle involves altering the effective length or compression of the spring through a threaded mechanism.

Typically, kierresäätö utilizes a threaded rod or screw that interacts with the spring. By turning the screw, either the compression or extension of the spring can be increased or decreased. This allows for fine-tuning the force exerted by the spring to meet specific operational requirements. For example, in a thermostat, kierresäätö might be used to set the temperature at which a switch engages. Similarly, in certain types of valves or actuators, it can adjust the opening or closing pressure.

The advantage of kierresäätö lies in its simplicity and the ease with which adjustments can be made. It does not require specialized tools and can often be performed while the device is in operation, although safety precautions are always advised. The precision achievable depends on the thread pitch of the adjusting screw and the overall design of the mechanism. While widely used, the term kierresäätö itself is primarily found in Finnish technical literature and discussions.
