Coupling Selection & Installation Guide for HEIDENHAIN ROD426.000B-1000-ID295434EV
- Officially Recommended Coupling Models
For HEIDENHAIN ROD426 series encoders (сплошной вал, диаметр 6 мм), the officially specified couplings are:
| Coupling Type | Модель | Спецификация | Приложение |
| Disk coupling | К 17 (original HEIDENHAIN) | Bore 6 мм × 6 мм, длина 25 мм, high torsional stiffness, moderate misalignment compensation | High-precision applications such as servo motors and CNC machine tools |
| Oldham coupling | CPG series (например. MIKI PULLEY) | Bore 6 мм × 6 мм, good flexibility, minimal shaft reaction force | High-speed rotation and applications requiring vibration absorption |
| Bellows coupling | 6 мм × 6 мм | High flexibility, zero backlash, suitable for high-precision positioning systems | Robot joints and precision transmission devices |
Key Selection Criteria
- Matching bore diameter: Both ends must be 6 мм (consistent with encoder shaft diameter)
- Recommended length: 20–30 мм (avoid insufficient torsional stiffness from excessive length)
- Тип подключения: Clamping type (рекомендуется) or set-screw type (ensure no damage to encoder shaft)
- Материал: Алюминиевый сплав (легкий, good heat dissipation) or stainless steel (high strength, corrosion resistance)
- Coupling Installation Procedure
2.1 Подготовка
Clean the encoder shaft and motor shaft, removing oil, burrs and rust
Prepare appropriate tools (динамометрический ключ, dial indicator, cleaning agent)
Check flatness of encoder flange and mounting base (flatness error ≤ 0.02 мм)
2.2 Installation Flow
- Mount the encoder
Secure the encoder synchronous flange (Ø58 mm) to the equipment end cover using 3 M4 bolts at a torque of 1.5 Нм
Ensure tight, gap-free contact between flange and mounting base
- Install the coupling
First mount one end of the coupling onto the motor shaft and pre-tighten clamping bolts (torque 0.8–1.2 Nm)
Align the two shafts by adjusting the motor/encoder position, then attach the other end to the encoder shaft
Tighten all clamping bolts evenly and symmetrically to the torque specified in the coupling manual
- Concentricity calibration (critical step)
Measure radial runout (≤ 0.03 мм) and axial play (≤ 0.02 мм) using a dial indicator
Angular misalignment must be limited to ≤ 0.5° (disk coupling) or ≤ 1.0° (Oldham coupling)
Adjust motor position until the above accuracy is achieved
- Critical Installation Notes (Key Limits)
| Misalignment Type | Maximum Allowable Value | Consequence of Exceedance | Correction Method |
| Radial misalignment | ≤ 0.05 мм | Extra load on encoder bearings, reduced service life, signal fluctuation | Adjust motor position, compensate with flexible coupling |
| Angular misalignment | ≤ 0.5° (disk) / ≤ 1.0° (Oldham) | Coupling fatigue failure, encoder shaft bending | Realign, increase coupling length or use more flexible coupling |
| Axial misalignment | ± 0.5 мм | Gap variation between code disk and scanning head, signal loss | Control motor axial play, select coupling with axial compensation |
| Backlash | Zero backlash (рекомендуется) | Reduced positioning accuracy, lag during reverse motion | Select zero-backlash coupling (например. bellows type) |
Important Warnings
- Rigid connection is forbidden: Always use a flexible coupling. Never directly rigidly connect the encoder shaft to the motor shaft.
- Shaft load limits: Maximum permissible radial load 10 Н, axial load 5 Н; exceeding these will damage bearings.
- Installation sequence: Mount the encoder flange first, then the coupling, then calibrate concentricity. Reverse order is strictly forbidden.
- Защита: Install a protective cover after mounting to prevent dust and oil ingress and maintain IP64 rating.
- Обслуживание & Поиск неисправностей
4.1 Регулярное техническое обслуживание
-Regularly check coupling bolt tightness (каждый 3 месяцы)
Clean encoder housing to avoid poor heat dissipation
Monitor encoder output signals; inspect coupling if abnormalities occur
4.2 Распространенные неисправности & Решения
| Симптом | Возможная причина | Решение |
| Signal fluctuation / missing pulses | Loose coupling or excessive concentricity error | Retighten bolts and recalibrate concentricity within limits |
| Excessive encoder heating | Excessive radial load, bearing wear | Check alignment, replace damaged coupling and bearings |
| Coupling breakage | Excessive angular misalignment beyond compensation | Use more flexible coupling and perform precise realignment |
- Selection Advice & Альтернативы
Recommendations by Application
High-precision positioning: Prefer original HEIDENHAIN K17 disk coupling for maximum accuracy and stability
High-speed rotation (>8000 об/мин): Recommended Oldham coupling (например. CPG series) with low shaft reaction force to protect encoder bearings
Суровые условия: Stainless steel couplings for improved corrosion resistance
Экономически чувствительные проекты: High-quality domestic 6 мм × 6 mm disk couplings with performance close to original parts
Complete List of HEIDENHAIN Encoders
- Encoder Classification Overview

Key Notes for Replacement Selection
- Mechanical Compatibility Priorities
- Shaft diameter and length: Must strictly match 6 мм × 9.5 мм, otherwise coupling installation will be difficult or bearings may be damaged
- Flange dimensions: Verify centering ring diameter (50 мм) and mounting holes (3×M4 on Ø42 mm circle)
- Housing diameter: Ø58 mm is standard; ensure sufficient installation space
- Согласование электрических параметров
| Параметр | Must Be Identical | Compatible Range |
| Signal Type | TTL push-pull output (А, Б, Z channels) | Cannot be changed, otherwise the control system cannot recognize |
| Напряжение питания | 5 V ±10% DC | Some models support auto-adapt 5V/12V/24V; native 5V models preferred |
| Pulses | 1000 P/R | Adjustable via system settings, but consistency recommended |
| Макс. Скорость | ≥16,000 rpm | Lower values may restrict equipment performance |
- Installation and Application Recommendations
- Coupling selection: All replacement models require 6 мм × 6 mm flexible couplings (например. HEIDENHAIN K17 or equivalent)
- Concentricity calibration: После установки, radial runout ≤ 0.03 mm and angular misalignment ≤ 0.5° must be verified
- Защита: Ensure replacement model has IP ≥ IP64; IP65/IP67 recommended for harsh environments
- Signal testing: After replacement, perform signal integrity test to ensure no pulse loss or interference
