Külgvahe

Külgvahe, also known as side clearance or lateral play, refers to the amount of space or looseness between two adjacent mechanical parts. This gap is intentionally designed into many systems to allow for movement, thermal expansion, or manufacturing tolerances. For instance, in automotive applications, külgvahe between gears in a transmission prevents them from binding under load or temperature changes. Similarly, in precision engineering, külgvahe in bearings allows for smooth rotation without excessive friction or wear.

The presence and measurement of külgvahe are critical for the proper functioning and longevity of mechanical assemblies. Too little külgvahe can lead to increased friction, heat generation, and premature wear, potentially causing parts to seize or break. Conversely, excessive külgvahe can result in vibration, noise, reduced precision, and instability. Engineers carefully calculate and control külgvahe during the design and manufacturing phases, often specifying tolerances to ensure the desired performance. Methods for measuring külgvahe include using feeler gauges, dial indicators, or more advanced optical or laser measurement systems. The concept of külgvahe is fundamental in mechanical design and is encountered across a wide range of industries, from aerospace to consumer electronics.
