Helical Worm Geared Motors
The Cost-effective Angular Geared Motor
Helical worm geared motors are the favorably-priced solution for drives with angular geared motors. The efficiency is significantly better than that of pure worm geared motors due to the implementation as helical-worm geared motors. Due to the worm gear stage, high ratios can be implemented within small envelope dimensions. Further, helical worm geared motors represent an extremely quiet drive solution. Helical worm geared motors represent the most cost-effective solution for angular geared motors in the lower torque range.
MOTOX helical worm geared motors are available in the power range up to 11 kW and rated gear unit torques up to 1,590 Nm.
The geared motors are available in the following versions:
- Foot or flange-mounting versions
- Version with torque bracket
- Solid or hollow shaft
- ollow shaft with key connection, shrunk-on disk, splines
An Overview of the Technology
|Gear unit designation||No. of stages||Ratio range||Max. rated gear unit torque|
|C28||2 stage||25,28 – 372||118 Nm|
|C38||2 stage||9,67 – 320,67||243 Nm|
|C48||2 stage||9,67 – 320,67||387 Nm|
|C68||2 stage||11,67 – 364||687 Nm|
|C88||2 stage||11,15 – 440,70||1.590 Nm|
Further, double geared motors with 4 and 5 stages are available with gear ratios of i = 324…33,491.
Helical worm geared motors are, for example, used in wastewater systems and in theaters.
