Cylindrical Worm Gear Drives

Due to their multiple mounting possibilities worm-gear drives are employed in almost all branches of industry.
Their special features are the crossed axes and a wide range of gear ratios extending in one step from i = 5 to i = 100. The sliding motion of the tooth flanks ensures silent and vibration dampened operation. The simultaneous meshing of several teeth and the line contact result in a high load bearing capacity.

Overview ATLANTA Cylindrical Worm Gear Drives program:

  • 6 sizes: centre distance 40, 50, 63, 80, 100 and 125 mm
  • 11 ratios: 6,75; 9; 12; 14; 19; 29; 39; 52; 62; 82 and 109:1
  • Worm flanks ground, steel hardened, shaft ends soft
    Worm gears of special worm-gear bronze
  • Tooth profile: K DIN 3975/76
  • Gearing grade: 7 fs
  • right-hand


As regards their load bearing capacity, ATLANTA worm-gear drive units are classified according to centre distances.
The maximum loading values indicated in the table have been calculated for standard worm drives (without cooling fan) and adequate dip-feed lubrication using synthetic gear oil (polyglycol basis). In the case of lubrication with mineral oils the load values are reduced by 30–40 %.
