Радиально-упорные шарикоподшипники are a specific type of ball bearing designed to handle both radial and axial loads simultaneously. Они достигают этого благодаря уникальному дизайну своих внутренних и внешних гонок, которые смещены друг от друга. Это смещение создает угол между гоночной трассе и шариками, allowing them to support thrust loads in one direction.
Selecting the right angular contact ball bearing involves considering several factors
1. Load and Speed
Type of Load: Determine whether the primary load is axial, радиальный, или комбинация того и другого. Angular contact bearings are ideal for combined loads, especially when the axial load is significant.
Magnitude of Load: Calculate the expected radial and axial loads the bearing will experience. This will help you choose a bearing with the appropriate load capacity.
Скорость вращения: Consider the desired operating speed. Some bearings are better suited for high-speed applications than others.
2. Bearing Design:
Угол контакта: The contact angle affects the load distribution within the bearing. Higher contact angles handle higher axial loads but have lower radial load capacity. Choose an angle based on your specific load requirements.
Number of Rows: Single-row bearings are common, but double-row and four-row designs offer higher load capacity.
Cage Material: Cages can be made from various materials like steel, латунь, or polyamide. Consider factors like temperature, смазка, and speed when choosing the cage material.
3. Условия эксплуатации:
Температура: High temperatures can affect bearing performance and lifespan. Choose a bearing with a suitable operating temperature range
Смазка: Proper lubrication is crucial for bearing performance and longevity. Select a bearing compatible with your chosen lubrication method (смазка или масло).
Среда: Consider environmental factors like moisture, пыль, and corrosive agents. These factors may necessitate special materials or seals.
