Фланцевые подшипники являются важными компонентами в различных промышленных применениях, Обеспечение поддержки вращающихся валов при обеспечении плавного и эффективного движения. Правильная смазка необходима для минимизации трения, уменьшить износ, и продлить срок службы подшипника. Неадекватная смазка может привести к перегреву, premature failure, and increased maintenance costs.Lubricating flange slewing bearings is crucial for their longevity and performance. Here’s a comprehensive guide on how to do it correctly.
Flange Bearing Lubrication
1. Understanding Your Bearing:
Bearing Type: Different types (например, single-row ball, double-row ball, roller) have slightly different lubrication needs. Consult the manufacturer’s specifications.
Seal Type: Bearings often have seals to protect the internal components from contamination. The seal design (например, contact seals, labyrinth seals) may influence lubrication procedures.
Условия эксплуатации: Factors like load, скорость, температура, and environment significantly impact lubrication frequency and grease type.
2. Importance of Proper Lubrication:
Reduced Friction and Wear: Lubrication minimizes friction between the rolling elements (шарики или ролики) and the raceways, preventing wear and extending bearing life.
Рассеивание тепла: Grease helps dissipate heat generated by friction, preventing overheating and potential damage.
Corrosion Protection: Grease acts as a barrier against moisture and contaminants, protecting the bearing from corrosion.
Герметизация: Grease contributes to sealing the bearing, keeping contaminants out and lubricant in.
3. Lubrication Materials (Grease):
Choosing the Right Grease: Select a grease specifically designed for slewing bearings and recommended by the bearing manufacturer. Consider these factors:
Base Oil Viscosity: Higher viscosity for heavy loads and slow speeds, lower viscosity for lighter loads and higher speeds. ISO VG 150 to VG 460 are common ranges.
Thickener Type: Lithium complex greases are a popular choice due to their good water resistance, high-temperature performance, и грузоподъемность.
Calcium sulfonate greases are also excellent for harsh environments.
Additives: EP (Extreme Pressure) additives for high loads, AW (Anti-Wear) additives for general wear protection, and corrosion inhibitors for rust prevention.
Temperature Range: Ensure the grease’s operating temperature range is suitable for your application.
Совместимость: If you’re switching grease types, ensure compatibility with the previous grease to avoid issues. It’s often best to completely clean the bearing when switching greases.
Never Mix Greases of Different Types: Mixing incompatible greases can lead to thickening, износ подставки для ног и износ спинки сиденья, or separation, which can damage the bearing.
4. Lubrication Procedures:
Частота: This is highly dependent on the operating conditions and the manufacturer’s recommendations. A general guideline is:
Легкая обязанность: Каждый 100-250 operating hours.
Средняя нагрузка: Каждый 50-100 operating hours.
