FAQs
Q: How to select welding roller frame reducer for welding turning rolls / welding rotator? A: Provide workpiece tonnage, drive quantity (2‑drive / 4‑drive), required rotating speed, motor power, shaft dimensions and mounting form. We select suitable JA / JB / JC / EP planetary model for your pressure‑vessel or tank welding system.
Q: What is lead‑time for custom welding rotator drive gearbox? A: Standard models support fast shipment. Custom gear ratio, shaft or mounting dimensions require technical review to confirm production lead‑time.
Q: What are key installation & maintenance points? A:
- Keep high coaxiality between reducer output shaft and roller‑frame input shaft.
- Fill N320 gear oil to oil‑gauge center line before commissioning.
- First oil change after 20 running‑days; every 3 months for continuous duty; every 6 months for ≤8 h/day operation.
- Stop running if oil temperature＞100 ℃ or abnormal noise / vibration occurs.
- Pre‑heat lubricant oil above 0 ℃ for cold startup below 0 ℃.
Q: Can your reducer replace existing gearbox on old welding turning rolls for retrofit projects? A: Yes. We support retrofit replacement for legacy welding roller frame equipment. Please send us your old reducer’s overall drawing, shaft dimension, mounting hole layout and operating parameters. Our engineering team will verify mechanical interface compatibility and offer matching replacement solution, avoiding modification to your original roller‑frame main structure。
Q: What kind of operating environment is suitable for welding roller frame reducer? Can it work near welding spatter and metal dust? A: The reducer is designed for workshop welding‑fabrication environment with welding spatter and metal dust. Keep vent and oil‑plug area free from heavy debris accumulation. For extra‑dusty sites, add external protective cover. Operating ambient should stay within ‑20℃~45℃. Avoid long‑term direct splash of welding slag onto housing surface。
