MHI HASEG Worm Gear Reducer SCHV Series

MHI HASEG Worm Gear Reducer SCHV Series is a single‑stage, vertical‑shaft hollow‑output worm gear reducer that combines compact design with high efficiency and self‑locking safety. Engineered with MHI HASEG’s precision‑machined Niemann tooth profile and robust materials, the SCHV Series delivers reliable torque transmission, space‑saving installation, and easy maintenance for a variety of vertical power‑transmission applications.

Key Features

 

1. Vertical Hollow‑Shaft Configuration

The SCHV Series features a vertical input and hollow output shaft, enabling direct coupling of driven elements (e.g., shafts, spindles) without additional adapters, ideal for space‑constrained or top‑down installations.

 

2. High‑Efficiency Niemann Tooth Profile

Special concave‑convex gear flanks maximize surface contact, promote uniform load distribution, and retain a stable oil film, resulting in smooth, low‑noise operation with minimal wear.

 

3. Self‑Locking Safety

Low lead‑angle worm geometry prevents back‑driving, providing built‑in holding power under load without the need for external brakes—crucial for vertical lifts, tilting equipment, and hoists.

 

4. Robust Construction & Durability

Hardened alloy‑steel worm shafts and high‑grade bronze worm wheels resist shock and axial/radial loads. Housing and bearing materials are selected for extended service life in demanding environments.

 

5. Easy Maintenance & Lubrication

Standard splash lubrication uses specified Klüber SYNTHESO HT or SYNTH GH6 oils. Accessible oil‑level gauges, filler/drain ports, and external grease nipples simplify periodic servicing.

 

6. JIS‑Compliant Dimensions

All mounting faces, shaft fits, and tolerances adhere to JIS B1301‑1976 standards (W1/W2 h9/N9), ensuring interchangeability and straightforward integration into existing systems.
