Achieving Zero-Backlash in Worm Gear Pairs

Life is full of opposing views. If you are heading to the beach, then you want to have the “perfect” beach body. This requires a strict adherence to a healthy diet and a strong gym regimen. After a fun day in the sun, you want to relax with friends over a few beers and some great eats. However, relaxing in this manner will change your beach bod into a Dad bod. With worm gear pairs, there is a similar situation. You design the system to achieve a certain speed reduction, at a particular torque load, but the backlash in the system throws off the repeatability of the mechanism.
