Product catalog summary

Overview of NF Series Planetary Gearboxes

The NF Series planetary gearboxes are designed for high precision, rigidity, and torque transmission. They feature a monoblock housing, helical gears, and integrated planetary design to optimize power transmission, reduce noise, and improve overall efficiency.

Key Design Features

Monoblock Housing: Enhances structural rigidity and ultimate tensile stiffness.
High Precision Bearings: Support higher radial and axial load capacities.
High Performance Oil Seal: Reduces friction, increasing efficiency and ensuring IP protection for continuous operation up to 90°C.
Helical Gear and Integrated Planetary Design: Provide increased torsional torque and optimized power transmission.
Low Noise and Improved Precision: Designed to minimize operational noise and backlash.

Performance Parameters

The gearboxes are characterized by the following critical parameters:

Rated Output Torque (T_N): Varies by model, supporting high torque applications.
Max Acceleration Torque (T_B Max): Defined for emergency stop and dynamic load conditions.
Input Speed: Rated and maximum input speeds are specified for each model.
Backlash: Available in ultraprecise, precise, and standard classes to suit different precision requirements.
Radial and Axial Load Capacities (F_rB and F_aB): High load points ensure durability under demanding conditions.
Tilting Moment and Rigidity: High torsional rigidity supports stable operation under load.
Service Life and Efficiency: Long service life with efficiency optimized through lubrication and design.
Operating Temperature: Continuous operation guaranteed up to 90°C.
Protection Class: IP67 ensures protection against dust and water ingress.
Noise Level: Low noise operation measured at rated speeds without load.

Output Shaft Options and Dimensions

The NF Series offers two main output shaft types:

S2 Keyed Shaft Output with various diameters depending on the model.
S1 Smooth Shaft Output also available with model-specific dimensions.

Note that input end dimensions depend on the motor used, and detailed drawings are required for final confirmation. When motor shaft diameters are small, shaft sleeves are recommended, with corresponding dimension reductions indicated.

Installation and Mounting

Mounting position is flexible (any direction).
Through-hole dimensions and bolt sizes (e.g., 4-M10, 4-M12) vary by model and stage.

Lubrication and Maintenance

Use of synthetic lubricant is recommended for optimal performance.
Lubrication intervals and service life depend on operating conditions.

Summary of Critical Recommendations

Confirm motor input dimensions with detailed drawings before installation.
Consider shaft sleeve usage for small motor shafts to maintain proper fit and performance.
Ensure operating conditions do not exceed specified temperature and load limits.
Choose appropriate backlash class based on precision requirements.
Maintain lubrication and monitor for noise or performance changes to ensure longevity.

This summary captures the essential technical specifications, design features, and operational guidelines for the NF Series planetary gearboxes, facilitating informed selection and application in precision mechanical systems.
