Assembling Components using the Slider Connection
Slider connections are used to enable translation along a single axis. For
example, an elevator door is representative of a Slider connection, as it slides
back and forth in one direction and is unable to rotate about any axis. A
piston in an engine is another example of a Slider connection. In the figures,
the hedge trimmer blade is yet another example of a Slider connection.
Slider connections require two constraint rules that limit their degrees of
freedom in a single direction. These two constraint rules are:
• Axis Alignment — The axes or cylindrical surfaces you select as references
determine the axis of free translation.
• Rotation Reference — The datum planes or planar surfaces you select with
the axis alignment restrict all rotational movement.
