Two of the many speed changing mechanisms in a conventional lathe headstock has been explained in this video with the help of 3 dimensional models.
Starting off with the cone-pulley drive, its working, view from different angles, and the basic principle, this video goes on to explaining how the belt positions are changed or switched, when a different rpm is needed.
Noting that a cone pulley drive can only give 4-5 speed variations, the video moves on to back-geared drives, which doubles the number of speed variations by introducing a compound gear on a parallel shaft.
