kutistuskiinnitys
Kutistuskiinnitys, also known as shrink fitting or heat shrinking, is a method used to fasten components together by exploiting the thermal expansion of materials. This technique involves heating one part of a joint, typically a sleeve or ring, causing it to expand. While expanded, this part is then fitted over a cooler, stationary component. As the heated part cools, it contracts, creating a tight, interference fit with the inner component. Conversely, in some applications, the inner component can be cooled to cause contraction, allowing it to be inserted into a slightly smaller outer component.
The effectiveness of kutistuskiinnitys relies on the predictable expansion and contraction properties of the materials involved.
