Coupling Selection & Installation Guide for HEIDENHAIN ROD426.000B-1000-ID295434EV

1. Officially Recommended Coupling Models

For HEIDENHAIN ROD426 series encoders (솔리드 샤프트, 지름 6 mm), the officially specified couplings are:

주요 선택 기준

1. Matching bore diameter: Both ends must be 6 mm (consistent with encoder shaft diameter)
2. Recommended length: 20–30 mm (avoid insufficient torsional stiffness from excessive length)
3. 연결 유형: Clamping type (추천) or set-screw type (ensure no damage to encoder shaft)
4. 재료: 알루미늄 합금 (경량, good heat dissipation) or stainless steel (고강도, corrosion resistance)
5. Coupling Installation Procedure

2.1 준비

Clean the encoder shaft and motor shaft, removing oil, burrs and rust

Prepare appropriate tools (토크 렌치, dial indicator, cleaning agent)

Check flatness of encoder flange and mounting base (flatness error ≤ 0.02 mm)

2.2 Installation Flow

1. 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 Nm

Ensure tight, gap-free contact between flange and mounting base

2. 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

3. Concentricity calibration (critical step)

Measure radial runout (≤ 0.03 mm) and axial play (≤ 0.02 mm) 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

3. Critical Installation Notes (Key Limits)

중요한 경고

1. Rigid connection is forbidden: Always use a flexible coupling. Never directly rigidly connect the encoder shaft to the motor shaft.
2. Shaft load limits: Maximum permissible radial load 10 N, 축방향 하중 5 N; exceeding these will damage bearings.
3. Installation sequence: Mount the encoder flange first, then the coupling, then calibrate concentricity. Reverse order is strictly forbidden.
4. 보호: Install a protective cover after mounting to prevent dust and oil ingress and maintain IP64 rating.
5. 유지 & 문제 해결

4.1 정기 유지 관리

-Regularly check coupling bolt tightness (모든 3 개월)

Clean encoder housing to avoid poor heat dissipation

Monitor encoder output signals; inspect coupling if abnormalities occur

4.2 일반적인 결함 & 솔루션

5. 선택 조언 & 대안

Recommendations by Application

고정밀 위치 결정: Prefer original HEIDENHAIN K17 disk coupling for maximum accuracy and stability

High-speed rotation (>8000 rpm): Recommended Oldham coupling (예를 들어. CPG series) with low shaft reaction force to protect encoder bearings

가혹한 환경: Stainless steel couplings for improved corrosion resistance

비용에 민감한 프로젝트: High-quality domestic 6 mm × 6 mm disk couplings with performance close to original parts
