Our Range Of Double Reduction Worm Gear Motor

Searching for a Double Reduction Worm Gear Motor for maximum output torque and ultra-slow rotational speeds from a compact drive assembly? As an authorised UK stocking distributor, Engineers Mate supplies a comprehensive range of Double Reduction Worm Gear Motors. By coupling two single-stage worm gearboxes in series to an electric motor, these specialised geared units deliver extreme speed reduction ratios (up to 5000:1) without requiring massive, space-consuming industrial gearboxes.

Our inventory features industry-leading manufacturers including TEC Motors (NMRV / PCRV series) offering modular, high-torque gear motors tailored for heavy-duty industrial automation.

Extreme Reduction Ratios & Inherent Self-Locking
Single worm gearboxes typically reach practical reduction limits around 100:1. Double reduction units multiply the reduction ratios of two combined worm gear sets (e.g., a 50:1 primary box combined with a 60:1 secondary box creates an impressive 3000:1 overall reduction).

This dual-stage configuration offers significant engineering advantages:
• Ultra-Low Output Speeds: Reduces standard motor speeds (1400 RPM) down to under 1RPM, delivering incredible output torque with precise positional control.
• Inherent Irreversibility (Self-Locking): High overall reduction ratios create natural static self-locking capabilities, preventing the output shaft from being back-driven by the load. This adds an inherent mechanical safety layer for lifting and inclined holding applications.
• Compact Right-Angle Geometry: The 90° shaft configuration allows high-torque drives to fit neatly into tight machine frames where inline gearboxes cannot fit.

Technical Specifications & Build Profile:
• Modular Construction: Lightweight die-cast aluminium bodies for smaller combinations (up to frame size 090) and heavy-duty cast iron housings for larger sizes (110–150+).
• Motor Mounting & Supply: Paired with single phase (230V) or three phase (400V) IEC electric motors, with options for brake motors for instant holding.
• Shaft & Mounting Flexibility: Available with hollow output shafts as standard, or solid single/double output shafts, torque arms, output flanges, and foot-mounting kits.
• Lubrication: Pre-filled with synthetic long-life lubricant for maintenance-free operation in standard mounting positions.

Typical Industrial Applications
Double reduction worm gear motors are essential for heavy, slow-speed machinery requiring continuous high torque:
• Slow Speed Agitators & Mixers: High-viscosity liquid and chemical compounding.
• Heavy Conveyors & Elevators: Continuous low-speed material handling under heavy static loads.
• Winches & Hoisting Systems: High reduction for heavy pulling and lifting operations.
• Rotary Indexing Tables & Valve Actuators: Fine positional tuning and steady, slow-rotation power.

By supplying certified double reduction gear motors with complete technical backup, Engineers Mate ensures your plant achieves maximum drive torque, mechanical reliability, and efficient space utilisation.
