Installation steps of WD250-53-V worm gear reducer

The installation of WD250‑53‑V (center distance 250 mm, i≈53, single-stage, V-shaped installation) is carried out according to the standard process of 'Preparation → Foundation and In-place → Centering → Lubrication and Ventilation → Running and Loading ', focusing on rigid foundations, precision centering on double-plane surfaces, correct oil filling and temperature rise monitoring.

Standard installation steps:

1. Unboxing and inspection

• Check that the nameplate is consistent with the model; check whether the appearance, oil seal, and ventilation device transportation blockage are intact; count the accessories.

2. Installation environment and basics

• Dry and well ventilated, with a surrounding ≥500 mm of maintenance space; ambient temperature -5~+40℃.

• Rigid foundation, horizontality ≤0.1 mm/m; use anchor bolts and secondary grouting; first rough adjustment and then fine adjustment.

3. Firm the foot in place

• Lifting in place; the foot and flange are not tight at the same time to prevent the body from deforming; gradually tighten to the specified torque according to the diagonal line.

4. Input shaft centering (motor end)

• Double-meter method or laser centering; parallel offset ≤0.05 mm; angle deviation ≤0.02 mm/m; measure and record in two planes perpendicular to each other.

• Choose a suitable elastic coupling and control the deviation according to its compensation amount and the instruction manual.

5. Output shaft assembly (working machine end)

• No hammering; priority is given to using threaded holes/working equipment; guarantee axial freedom of the output shaft without additional axial constraints.

• After assembly, the manual wheel should be light and free of jamming.

6. Lubrication and ventilation

• Inject oil according to the instruction manual brand and oil level (about 2/3 of the oil window when shutting down); loosen/replace the ventilation screw plug before operation (remove transportation blockage).

• If it is V-shaped (side-mounted/top-mounted), the oil level and lubrication method must be checked according to the installation position, and if necessary, force lubrication or cooling should be added.

7. Electrical and Safety

• The inlet port of the junction box is facing downward; make sure that the phase sequence and rotation direction are consistent with the working machine; set overload/temperature rise protection.

8. Running together without load

• 1–3 h, monitor temperature rise, noise, vibration and leakage; temperature rise ≤60 K; abnormal shutdown and inspection.

9. Graded loading and acceptance

• 25%→50%→75%→100%, upgrade after each stage is stable; check the oil level, temperature rise and connection tightening.

• Retain the parallel report, oil level/oil quality record, temperature rise curve and vibration data.
