NUODUN RV Worm Gear Reducers

MANUFACTURER DOCUMENTATION

Overview

Nuodun’s RV range uses a compact die-cast aluminum-alloy square housing with multiple motor and shaft interfaces. The official page gives ratios of 7.5–100, with combined two-stage selections reaching 10,000, and an output-torque envelope of 24.6–1,192 Nm. Input power is quoted at 1,400 rpm. IEC and NEMA motor interfaces, solid input shafts and several output formats are listed as options. The source mentions self-locking under certain conditions; this must not be treated as a safety brake or a universal characteristic. Ask for a model-specific selection covering efficiency, temperature rise, mounting position and back-driving behavior.

Model configuration table

The source page provides a series overview rather than a complete model/ratio rating table. Use the manufacturer link above for selection drawings and confirm the precise operating point before ordering.

Before you specify this gearbox

Check efficiency, heat dissipation, duty and back-driving behavior for the particular model. Do not assume that every worm gearbox is self-locking.

Confirm continuous, peak and emergency-stop load limits separately.
Match the motor flange, shaft, mounting orientation and lubrication requirements.
Request the current drawing revision and selection calculation from the manufacturer.
