Control surface backlash
Webbacklash values. 5) Run the program in the following manner: a. At line N2, the control will be in the waiting state. Adjust the dial of the surface indicator to zero on the needle, then press the START button to continue. b. At line N7, the control will be in the waiting state. Read the indicator dial to see 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.
