Description
Components of a technical application that fulfil certain functions in structures are known as machine elements. Machine elements can be both single components and assemblies.
Simple machine elements such as screws, cylinder pins, feather keys or seals are defined according to standards and therefore can be exchanged without difficulty.
More complex machine elements such as bearings, couplings, gears or shafts are standardised in only certain important properties, and as such are not fully interchangeable.
This section presents the following machine elements:
• various connecting elements
• roller bearings
• various types of gears
