MHI HASEG Worm Gear Reducer SCOH Series

The MHI HASEG Worm Gear Reducer SCOH Series is a compact, two‑stage vertical‑shaft worm‑gear reducer engineered for high overall reduction ratios in space‑constrained, vertically oriented installations. Leveraging MHI HASEG’s advanced Niemann tooth geometry and precision machining, the SCOH Series delivers reliable torque transmission, inherent self‑locking, and simplified maintenance for mixers, hoists, conveyors, and other industrial equipment.

Key Features

 

  1. Two‑Stage Niemann Tooth Geometry

     

    • Dual‑worm stages achieve large reduction ratios (see “Typical Specifications”).

    • Optimized concave‑convex tooth flanks distribute load evenly, reducing wear and extending service life.

  2. Vertical Shaft Configuration

    • Space‑saving layout ideal for top‑down or bottom‑up power transmission in vertical mixers, hoists, and lift applications.

    • Mounting faces and oil chambers separated per stage to ensure proper lubrication (for sizes 100–250).

  3. High Load Capacity & Durability

    • Worm shafts: hardened alloy steel; worm wheels: high‑grade bronze.

    • Robust housing machined to JIS B1301‑1976 tolerances for precise alignment and minimal backlash.

  4. Efficient Lubrication System

    • Standard splash (immersion) lubrication using KLÜBER “SYNTHESO HT” or “SYNTH GH6” oils.

    • Optional forced‑lubrication for high‑speed or heavy‑load applications; separate oil‑level gauges and filler/drain ports on each stage.

  5. Self‑Locking Safety

    • Low lead‑angle worm stages prevent back‑driving, providing built‑in mechanical holding power without requiring additional braking devices.

  6. Maintenance‑Friendly Design

    • External grease nipples for bearing relubrication.

    • Stage‑specific oil‑level sight glasses and accessible filler plugs simplify inspections and oil top‑up.

Applications

 

  • Vertical Mixers & Agitators: Efficient torque delivery with built‑in holding power.

  • Elevators & Hoists: Self‑locking safety in lift mechanisms.

  • Vertical Conveying Systems: Space‑efficient power transmission.

  • Packaging & Food Processing: Quiet, hygienic operation with contained lubrication.

  • Chemical & Textile Machinery: Stable, low‑vibration performance in vertical orientations.


Why Choose the SCOH Series?

 

  • High Reduction in Compact Vertical Form: Two‑stage design delivers large ratios without excessive length.

  • Reliability & Longevity: Niemann tooth profile and quality materials ensure durable operation under heavy loads.

  • Safety: Inherent self‑locking eliminates unintended back‑driving.

  • Ease of Service: Accessible lubrication points and sight gauges minimize downtime.

  • Global Support: Detailed MHI HASEG documentation and local Melink Automation expertise ensure smooth integration.
