DESCRIPTION

A high quality worm-drive gearbox that is compact, mates directly to a Nema 17 motor, and is affordable!

The ExoSlide worm-drive gearbox is ideal for Z drive applications, where GT2 belts can be used on the Z axis. A worm-drive gearbox offers the following advantages over lead-screws:
  • Tall Z heights easily accomplished with a belt.
  • Almost zero backlash, even after repeated use.
  • Can alleviate Z banding from wobbly or over-constrained lead screws.
  • No back drive design, so Z height won’t change when the motor is powered off.
Note: Do not remove the worm input shaft! Install on the Nema 17 motor in the pre-assembled delivered condition. The gearbox is pressure packed with moly-grease for long service life.

Refer to the drawing in the documents section for installation guidelines

The gear ratio is 10:1 (10 turns input for 1 turn output), which when paired with a GT2 20t pulley, has the same ratio as a TR8 lead screw with 2mm pitch and 2 starts (800 steps/mm using 16 microsteps). The output D shaft is 5mm, the same as the Nema 17 output shaft.
