CAUTION: Duplex worms and worm gears must be mated in a predetermined orientation. Please see the beginning of this section for details.
CAUTION: When duplex worms and worm gears are set at the reference tooth line, the backlash is zero.
CAUTION: Do not take heavy cuts when performing secondary operations on worm shafts to avoid bending them.
NOTE: If the worm and worm wheel are assembled to the standard center distance, it is designated to have a near zero backlash (+/-0.03).
NOTE: When the center distance is moved so as to reduce the backlash, V max is the maximum amount that you may shift without causing problems with gear mesh. It is not the recommended adjustment value.
NOTE: Allowable torques shown in the table are the calculated values according to JGMA Standards 405-01 when the worm is rotating at 600 rpm. The table below shows the allowable worm gear torques at selected worm speeds.
