TDNRV GEARBOX
Model: TDNRV – Cast Iron Worm Gear Reducer
Introduction:
The TDNRV series is a heavy-duty worm gearbox with a cast iron housing, built for higher strength and torque compared to the TDNMRV aluminum version. It is designed for more demanding industrial environments where durability and shock resistance are critical.
Power Range / Specifications:
Center Distances Available: Typically 75, 90, 110, 130, 150 mm
Reduction Ratios: Similar to TDNMRV (e.g., 10, 15, 20, 30, up to 100)
Power Range: Commonly 0.37 kW to 15 kW
Material: Robust cast iron casing for high load tolerance
Mounting: Foot and flange options
Features: Higher thermal capacity, rigid structure, adaptable to harsh environments
Suitable Industries:
Heavy conveyors
Mixers and crushers
Agricultural machinery
Material handling systems
Equipment with continuous or intermittent shock loads
SPAIN TYPE GEARBOX
Model: Spain Type – Flange-Mounted Input Type
Introduction:
The Spain Type gearbox refers to a standardized input flange mounting style, widely used in the Spanish and Iberian industrial markets. It simplifies motor integration and offers compatibility with standard IEC motors.
Power Range / Specifications:
Input flange allows direct motor coupling
Typically available for TDNMRV/TDNRV sizes: 30–150
Designed for quick installation and removal
Ensures accurate alignment and vibration reduction
Suitable for both vertical and horizontal mounting
Suitable Industries:
European-designed conveyor systems
Agricultural equipment
Food processing machines
Anywhere IEC motor and reducer integration is needed quickly
SPLINE TYPE GEARBOX
Model: Spline Type – Shaft Output with Spline Coupling
Introduction:
The Spline Type refers to a gearbox output shaft design featuring internal or external splines, enabling secure torque transfer with minimal backlash. It is ideal for dynamic or load-changing environments.
Power Range / Specifications:
Typically used in TDNMRV and TDNRV output stages
Ensures torsional rigidity and zero slippage
Compatible with custom spline couplings or drive shafts
Available in several standard spline sizes (DIN, ISO formats)
Suitable Industries:
Servo-driven systems
Precision automation
Textile and packaging lines
Equipment with frequent start/stop torque demands
