worm GEARBOX
TDNMRV+TDNMRV GEARBOX
The TDNMRV + TDNMRV is a double-stage worm gearbox combination designed to achieve very high reduction ratios in compact form. It consists of two TDNMRV units coupled together, offering space-saving and enhanced torque multiplication.
Power Range / Specifications:
Input Power: Typically from 0.12 kW to 4 kW
Reduction Ratios: Can exceed i = 1000:1 depending on configuration
Mounting: Universal (foot or flange mounting)
Features: High torque output, compact structure, aluminum housing, good heat dissipation
Suitable Industries:
Conveyor and handling systems
Packaging lines
Textile machinery
Food processing equipment
Applications requiring compact gearboxes with very low output speeds
TDNMRV+TDNRV GEARBOX
Model: TDNMRV + TDNRV – Dual Worm Gear Reducer (Compact Heavy-Duty Configuration)
Introduction:
The TDNMRV + TDNRV configuration combines two different worm gear stages: TDNMRV (aluminum housing) and TDNRV (cast iron housing), offering both compact design and enhanced load capacity. This setup allows customized gear ratio configurations with reinforced mechanical durability.
Power Range / Specifications:
Input Power: Commonly from 0.18 kW to 7.5 kW
Reduction Ratios: Broad range — from moderate to extremely high (>1000:1)
Structure:
TDNMRV: lightweight, corrosion-resistant
TDNRV: heavy-duty, cast-iron for shock resistance
Mounting: Foot or flange, universal layout
Suitable Industries:
Heavy-duty conveyor systems
Lifting and hoisting equipment
Material handling in rugged environments
Industrial mixers and crushers
Applications requiring robust gear reduction with tight installation space
