This motor-worm-drive system is often used in toys and other small electrical devices. A worm drive is used on Jubilee-type hose clamps or Jubilee clamps. The tightening screw's worm thread engages with the slots on the clamp band. Occasionally a worm drive is designed to run in reverse, resulting in the worm shaft turning much faster than the ...
WORM drives preceded the invention of the CD-R, DVD-R and BD-R.An example was the IBM 3363. [1] These drives typically used either a 5.1 in (13 cm) or a 12 in (30 cm) disc in a cartridge, with an ablative optical layer that could be written to only once, and were often used in places like libraries that needed to store large amounts of data.
The slewing drive is a modernized take on the worm drive mechanism, which dates back many centuries and was widely used during the Renaissance Era. Pappus of Alexandria (3rd century AD), a Greek mathematician, is credited with an early version of the endless screw, which would later evolve into the worm drive. [1]
Another handy attribute: worm-drive hose clamps can be daisy-chained or "siamesed" to make a long clamp, if you have several, shorter than the job requires. Some things seen assembled with hose clamps include the tail boom on a GMP Cricket model helicopter , a homemade gas scooter , makeshift pipe hangers, mounts for rooftop TV and shortwave ...

Michel mounted a mixer motor onto a standard machete, as well as a worm wheel gearbox and a 2-inch circular blade. This invention, while actually working fairly effectively (if slowly), required an external generator, making it quite impractical. In creating this device, Michel effectively invented the worm-drive motor.
Additionally, their larger worm drive saw called the "SawSquatch" was the first 10-1/4-inch worm drive saw. [6] The following year, 2016, brought three new metal cutting saws, including the first 8-inch worm drive optimized for metal, a 12-inch dry cut saw and a 14-inch abrasive chop saw.
After the Great Depression, In 1928, Skil released the Model E Skilsaw, the first generation saw with a worm drive. In 1937, Edward Sterba built the first Model 77 with a 7 + 1 ⁄ 4-inch (180 mm) blade, considered the "workhorse on building sites". [6] The 75th anniversary of the Model 77 was in 2012.
