Do worm gears have backlash
Did you know?
Factors affecting the amount of backlash required in a gear train include errors in profile, pitch, tooth thickness, helix angle and center distance, and run-out. The greater the accuracy the smaller the backlash needed. Backlash is most commonly created by cutting the teeth deeper into the gears than the ideal depth. Another way of introducing backlash is by increasing the center distances between the gears. WebIn addition, milling heads and rotary tables are positioned using high-precision duplex worm drives with adjustable backlash.
