静压轴承 振动 Analysis与Monitoring

Key Takeaways:

Hydrostatic films damp vibration well, so unexpected vibration usually points to oil supply or process issues. A simple monitoring routine catches problems before they reach the workpiece.

Анализ и мониторинг вибрации гидростатических подшипников

Хорошее гашение, плохой сигнал

Гидростатика отлично гасит вибрацию, поэтому появление её — важный сигнал.

Что мониторить

Давление, расход, толщину плёнки в динамике. Плюс NAS 5 и 35±5°C.

Расшифровка

Вибрация с ростом нагрузки — падение питания или заужение кармана. Независимая — процесс или фундамент.

🇻🇳 Tiếng Việt

Phân tích và giám sát rung động ổ thủy tĩnh

Giảm chấn tốt, tín hiệu xấu

Thủy tĩnh giảm chấn rất tốt, nên rung bất thường là tín hiệu quan trọng.

Giám sát gì

Theo dõi áp, lưu lượng, dày màng theo thời gian. Thêm NAS 5 và 35±5°C.

Đọc

Rung tăng theo tải — áp yếu hoặc hốc hẹp. Độc lập tải — quy trình hay móng.

Analyse et surveillance des vibrations des paliers hydrostatiques

Bon amortissement, mauvais signal

L'hydrostatique amortit très bien, donc une vibration inhabituelle est un signal clé.

Que surveiller

Pression, débit, épaisseur de film dans le temps. Plus NAS 5 et 35±5°C.

Interprétation

Vibration croissant avec la charge—alimentation ou tasche réduite. Indépendante—process ou fondation.

🇩🇪 Deutsch

Schwingungsanalyse und Überwachung hydrostatischer Lager

Gute Dämpfung, schlechtes Signal

Hydrostatik dämpft hervorragend, daher ist auftretende Vibration ein wichtiges Signal.

Was überwachen

Druck, Fluss, Filmdicke trendmäßig. Plus NAS 5 und 35±5°C.

Deutung

Vibration mit Last deutet auf Versorgung oder verengte Tasche. Lastunabhängig auf Prozess oder Fundament.

Good 阻尼, Bad Signal

一的静压 支撑's strengths为excellent 油膜 振动 阻尼. 该 means when unusual 振动 does appear, it为 meaningful signal—not normal behavior—and deserves prompt attention.

Hydrostatic vibration analysis

What以Monitor

Track cavity pressure, oil flow,与film thickness trend over time. Abrupt or drifting changes usually precede 精度 loss. Combined采用periodic checks的oil 清洁度 (NAS 5)与temperature (35±5°C), 该 gives early warning.

Interpreting Data

振动 该 rises采用load often indicates 供油压力 sag or restricted cavity. 振动 independent的load may point以 process or foundation. Because film itself为stable by design, most 振动 issues trace back以 供油 or external excitation—both fixable without opening 轴承.
