Double worm gear units
Irreplaceable despite low efficiency
Double worm gear units have a very low efficiency. Nevertheless, the combination of two worm gear units reduces the output speed at minimum space requirements, which may sometimes be the only solution. GFC supplies dual stage double worm gear units and double worm gear motors in three sizes with various transmission ratios. The drive unit can be designed as solid shaft or flange with coupling; the output drive as solid shaft, hollow shaft or in combination with an output flange. |
