Product catalog summary

Overview

The document presents technical details and specifications for the NER series high precision planetary gearboxes. These gearboxes are designed for high rigidity, high torque, and optimized power transmission with low noise and improved precision.

Main Features

  • High Precision Bearings: Provide increased radial and axial load capacity.
  • High Performance Oil Seal: Reduces friction, enhancing efficiency.
  • Protection Level: IP-rated protection ensures continuous operation up to specified temperatures.
  • Gear Types: Includes helical and bevel gears integrated into planetary designs for increased torsional torque and optimized power transmission.
  • Low Noise and Improved Precision: Designed to minimize operational noise and maximize accuracy.

Technical Specifications

The document includes detailed tables of gearbox parameters for various NER series models, including:

  • Center Distance (X) and Load Point (Z) dimensions.
  • Rated output torque (TN), maximum acceleration torque (TB), and emergency stop torque (TNOT).
  • Rated input speed (nN) and maximum input speed (nB).
  • Backlash categories: ultraprecise, precise, and standard.
  • Radial and axial forces (FrB, FaB) at output shaft center at 100 rpm.
  • Tilting moment, service life, efficiency (η), weight, operating temperature range, lubrication type (synthetic lubricant), and noise level (dB(A)).
  • Rotary inertia and mounting position flexibility (any direction).

Design and Assembly

The NER series features an integrated planetary design with options for helical and bevel gears to optimize power transmission and torque capacity. The assembly includes high precision bearings and oil seals to ensure durability and performance.

Output Shaft Options and Dimensions

Output shafts are available in two main types:

  • S2 keyed shaft output
  • S1 smooth shaft output

Dimensions vary by model and stage, with specific notes:

  • Input end dimensions depend on the motor and require detailed drawings for confirmation.
  • For smaller motor shaft diameters, a shaft sleeve is necessary, which reduces dimensions accordingly.

Dimension reductions with shaft sleeves are specified for each model and stage, ensuring compatibility with various motor configurations.

Critical Parameters and Limitations

  • Maximum radial and axial forces are specified for each model to avoid overload.
  • Operating temperature limits are defined to ensure continuous operation without degradation.
  • Backlash precision levels affect the gearbox's suitability for different precision requirements.
  • Noise levels are measured at rated speeds without load to guide application in noise-sensitive environments.

Recommendations and Best Practices

  • Provide detailed motor shaft drawings to confirm input end dimensions before assembly.
  • Use shaft sleeves when motor shaft diameters are small to maintain proper fit and performance.
  • Adhere to specified load and speed limits to ensure gearbox longevity and reliability.
  • Maintain lubrication with synthetic oils as recommended for optimal efficiency and protection.

Summary

The NER series planetary gearboxes offer a robust solution for applications requiring high precision, high torque, and efficient power transmission. Their design incorporates advanced bearing technology, optimized gear types, and flexible mounting options. Detailed technical parameters and dimensional data support proper selection and integration into various mechanical systems.
