MHI HASEG Worm Gear Set SRMR Series

The MHI HASEG Worm Gear Set SRMR Series is a premium, modular worm-and-worm-wheel assembly designed for OEMs and system integrators who demand flexible, high-precision gearing solutions. Crafted with MHI HASEG’s proprietary Niemann concave-convex tooth profile, the MHI HASEG Worm Gear Set SRMR Series delivers superior load capacity, quiet operation, and reliable self-locking performance in compact assemblies.

Key Features

1. Modular Design
   
   The MHI HASEG Worm Gear Set SRMR Series provides matched worm shafts and bronze worm wheels as a kit, allowing engineers to integrate the gearing into custom housings and achieve optimal center-distance configurations.
   
   

2. Advanced Niemann Tooth Profile
   
   With the MHI HASEG Worm Gear Set SRMR Series, each gear combination features a precision concave-convex profile that increases surface contact, enhances oil film retention, and minimizes Hertzian stress for extended life.
   
   

3. High Load & Torque Capacity
   
   The MHI HASEG Worm Gear Set SRMR Series uses hardened alloy-steel worms and high-strength bronze wheels, supporting torque ratings up to 20 000 Nm (size-dependent) and ensuring robust performance under heavy radial and axial loads.
   
   

4. Self-Locking Safety
   
   Thanks to its low lead-angle configuration, the MHI HASEG Worm Gear Set SRMR Series inherently resists back-driving, providing built-in load-holding capability without additional braking components.
   
   

5. Quiet, Smooth Operation
   
   Gear pairs in the MHI HASEG Worm Gear Set SRMR Series are finish-machined to tight tolerances, delivering whisper-quiet meshing and minimal vibration even at high input speeds up to 1 800 min⁻¹.
   
   

6. OEM Customization
   
   Available in center distances from 65 mm to 500 mm and standard reduction ratios from 5:1 to 50:1, the MHI HASEG Worm Gear Set SRMR Series can be tailored to meet specific design requirements for speed, torque, and footprint.
