  Single-Head (Double-Head) Small Modulus Worm

  Like a ball screw, the worm in a worm gear may have one or more starts - meaning multiple threads or spirals on the worm. For a single-start worm, each full revolution of the worm advances the gear by one tooth.
  The meshing of the worm and gear is a mixture of sliding and rolling actions, but the sliding contact is dominated by high reduction ratios. This sliding action creates friction and heat, which limits the efficiency of the worm gear to between 30% and 50%. To minimize friction, the worm and gears are made of dissimilar metals—for example, the worm might be hardened steel and the gears bronze or aluminum.

  Worm Shaft Series

  Worms are mostly made of carbon steel or alloy steel. Generally, 40 and 45 steels can be used for low-speed and heavy-duty worms that are not important, and they have been quenched and tempered. 15Cr or 20 Cr, 20CrMnTi, etc. are commonly used for high-speed and heavy-duty worms, and are carburized and quenched. After heat treatment, the hardness of the tooth surface can be improved and the wear resistance can be increased.
  With reverse self-locking function.
  Can have a larger reduction ratio.
  High transmission efficiency and stable operation.
  Large torque, strong applicability and large load capacity.
