If I'm understanding the workings, what is being suggested is to use the
worm as a slip coupling (which just happens to have a worm screw). If
you look at a cars drive shaft, you will see that it is in two parts so
that it can change length. Terrible ASCII graphic of car drive shaft:
+- this axle is fixed
|
v -------------+
========================= |||||| this axle can slip in and out
-------------+
What is proposed to use the worm gear:
the worm -+
+- this axle is |
| fixed V
V ////////////
============================ =================== this axle can slip
in and out
////////////
