It took me a while to learn this is a helical gear, but a special type of helical gear called "crossed helical gears". What type of gear would I need for this particular case, where there are two non-intersecting and non-parallel shafts, that are not exactly perpendicular? And worm gears operate on non-intersecting shafts at a right angle to each other. Bevel gears operate on intersecting shafts. It transmits torque from the hand crank to the Cone Gear Set, but it does so at a slight angle (as shown by the red lines in the photo below). However, the largest gear in the Cone Gear Set was a very peculiar gear that proved to be much more elusive. There is plenty of information on bevel gears online and Greg Frost's Parametric Involute Bevel and Spur Gear library seems like a good choice for this. The first component I began to explore was the Cone Gear Set, as it seems the most complicated.įor the twenty gears that generate the frequencies, it appears I could use a stack of bevel gears.

In this case the following command will download and store the key. In newer Debian the storage for the key is changed, more information can be found in the apt-key(8) NOTE: If you get errors about an expired key valid till, please re-import via the following command. To install the packages, the release key must be added with apt-key to the key-ring to allowĪpt-get / aptitude to validate the packages.
