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-mounted or flange-mounted designs
  • Design with torque arm
  • Solid shaft or hollow shaft designs
  • Hollow shaft with feather key, shrink disk, splined shaft
MOTOX helical worm gearboxes are part of the MOTOX modular system. With helical, bevel helical, helical worm, or variable speed gearboxes and three-phase AC motors with or without brakes, this system covers all possible drive combinations, right up to electronic variable speed drives.

MOTOX helical worm gearboxes are designed for continuous duty. The sealed gearbox housings, made from gray cast iron or aluminum, are strong and absorb vibrations. A housing cover is not required for installing toothed components, which means that the housings are extremely rigid. Radial shaft seals with dust-protection lips prevent oil from leaking out of the housing and dust and water from entering it. The gear wheels of the helical gear stages are milled and their surfaces hardened. The tooth flanks are ground or honed so that they are convex and corrected in terms of the profile.
