Ordering Information

This section explains the coding system for ordering gearboxes and related components. The code consists of multiple segments representing series, bearing type, input/output configuration, size, stages, ratio, output type, backlash precision, input flange code, motor shaft diameter, version, output gear details, gear module, teeth number, gear rotation direction, and installation height. Key points include:

• Series: NB, ND, NE, NF
• Bearing Types: V (Tapered roller), S (Deep groove ball), W (Medium cone angle), or Angular contact ball bearing (no letter)
• Input/Output: Straight (no letter) or 90-degree angle (R)
• Stages: Single stage (no letter), T (two stages with standard motor), A (two stages with large shaft motor)
• Output: Smooth shaft (S), Keyed shaft (S), or flange/expansion sleeve (no letter)
• Backlash Precision: P1 (extreme), P2 (high), P3 (standard)
• Input Flange Codes: Various codes indicating installation thread center distances and sequence codes
• Motor Shaft Diameter and Version: Multiple sizes and versions including original and variants (Z, P, B, K, M)
• Output Gear: Standard (G) or none; gear features include welded gears or integrated planetary carriers
• Gear Module and Teeth Number: Various modules and teeth counts available
• Gear Rotation Direction: Standard (S), Left-handed (L), Right-handed (R), or none
• Installation Height: Distance from output end to output gear, or none if no gear

Bolt Tightening Torque Values

Two tables provide recommended tightening torque values for motor mounting bolts, differentiated by material:

Steel Bolts (M10.9 Grade Screws)

• Bolt sizes range from M4×0.7P to M12×1.75P
• Hex socket sizes vary from 3 mm to 10 mm
• Standard torque values range approximately from 4.5 Nm to 110 Nm
• Torque ranges specify minimum and maximum recommended tightening torques

Aluminium Bolts (M10.9 Grade Screws)

• Similar bolt sizes and hex socket sizes as steel
• Torque values are generally lower than steel, ranging from about 3.5 Nm to 90 Nm
• Torque ranges also provided for safe tightening

Gearbox Input Flange Codes and Connection Details

This section lists various flange codes with corresponding motor dimensions, mounting hole pitch circle diameter (PCD), thread specifications, locating diameters and depths, and suitable motor overall lengths. Key points include:

• Flange codes such as DA, A, B, ZA, ZB, FA, FB, DC, DD, DE, DF, etc.
• Mounting hole PCD and thread specifications vary per flange code
• Locating diameters and depths are specified for precise motor alignment
• Suitable motor overall lengths are indicated for compatibility
• Connection flange coding rules clarify that:
• F+letter indicates non-standard flanges
• Z+letter indicates integrated models
• A/B/C/D... letters differentiate types with the same PCD
• D+letter indicates mounting hole PCD includes a decimal
• Specifications may vary by brand; final confirmation should be done using installation outline drawings

Summary

This document provides comprehensive ordering codes for gearboxes and components, detailed torque specifications for motor mounting bolts by material, and extensive flange connection data for motor compatibility. It emphasizes precision in ordering, installation, and assembly to ensure proper fit and function.
