Helical worm geared motors
The angular geared motor with a high power density
Bevel helical geared motors are angular geared motors where the gear unit output shaft is rotated through 90° to the motor shaft. Bevel helical geared units can either have a solid or a hollow shaft. Bevel helical geared motors represent the ideal solution for drive tasks where an angular geared motor with high power density is required with continuously high output torques.

MOTOX bevel helical geared motors are available in the power range up to 200 kW and rated gear unit torques up to 20 × 103 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 bevel helical gearboxes are part of the MOTOX modular system. With helical, parallel shaft, 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 bevel helical gearboxes are designed for continuous duty. The gearbox housings made of gray cast iron or aluminium are developed in 3D CAD and have an optimized structure in terms of rigidity and vibration absorption. 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. For the standard range, the bevel gear stage is milled, its surface is hardened, and it is lapped in pairs. Optimum running smoothness is also achieved thanks to the helical gears' helical teeth. Positioning the bevel gear stage as the second stage means that less noise is emitted. The output shaft is positioned at a right angle to the input shaft.
