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

1. Officially Recommended Coupling Models

For HEIDENHAIN ROD426 series encoders (solid shaft, diameter 6 มม), the officially specified couplings are:

Key Selection Criteria

1. Matching bore diameter: Both ends must be 6 มม (consistent with encoder shaft diameter)
2. Recommended length: 20–30 mm (avoid insufficient torsional stiffness from excessive length)
3. Connection type: Clamping type (ที่แนะนำ) or set-screw type (ensure no damage to encoder shaft)
4. วัสดุ: Aluminum alloy (lightweight, good heat dissipation) or stainless steel (high strength, ความต้านทานการกัดกร่อน)
5. Coupling Installation Procedure

2.1 การตระเตรียม

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

Prepare appropriate tools (ประแจแรงบิด, dial indicator, cleaning agent)

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

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 นิวตันเมตร

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 มม) and axial play (≤ 0.02 มม) 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)

Important Warnings

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 เอ็น, axial load 5 เอ็น; 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. การป้องกัน: Install a protective cover after mounting to prevent dust and oil ingress and maintain IP64 rating.
5. การซ่อมบำรุง & การแก้ไขปัญหา

4.1 การบำรุงรักษาตามปกติ

-Regularly check coupling bolt tightness (ทั้งหมด 3 เดือน)

Clean encoder housing to avoid poor heat dissipation

Monitor encoder output signals; inspect coupling if abnormalities occur

4.2 ข้อผิดพลาดทั่วไป & โซลูชั่น

5. คำแนะนำในการเลือก & ทางเลือก

Recommendations by Application

High-precision positioning: Prefer original HEIDENHAIN K17 disk coupling for maximum accuracy and stability

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

สภาพแวดล้อมที่รุนแรง: Stainless steel couplings for improved corrosion resistance

โครงการที่คำนึงถึงต้นทุน: High-quality domestic 6 มม. × 6 mm disk couplings with performance close to original parts
