Comments.Text: It seems from your question that you want to convert a continuous circular motion from the motor into an up and down motion with a range of 5cm - is that correct?

  I have a motor and some other components that move a machine vertically on the ground. Inside the machine I need to raise a part by 5 cm, up and down.
  
  Are there some common patterns that can move objects vertically (lift) using LEGO Technic? Torque comes from a motor powering gears.

  This is a mechanism that converts circular motion into [reciprocating motion](http://en.wikipedia.org/wiki/Reciprocating_motion). You may need to alter the design for your needs regarding height difference, stability etc.
