FAQs on GATE Previous Year Questions: Life of Bearing, Machine Design Video Lecture - Topicwise Question Bank for Mechanical Engineering
| 1. What is the life of a bearing? |  |
The life of a bearing refers to the number of revolutions or hours of operation that a bearing can sustain before it shows signs of wear or failure. It is a measure of the bearing's durability under normal operating conditions.
| 2. How is the life of a bearing calculated? | |
The life of a bearing is typically calculated using the L10 life formula, which is based on statistical analysis of a large number of bearings. The formula takes into account factors such as load, speed, lubrication, and material properties to estimate the average life of a bearing in millions of revolutions or hours.
| 3. What factors affect the life of a bearing? | |
Several factors can influence the life of a bearing, including the magnitude and direction of the load, rotational speed, temperature, lubrication, contamination, and the bearing's design and material. These factors can accelerate wear and fatigue, leading to a shorter bearing life.
| 4. How can the life of a bearing be extended? | |
The life of a bearing can be extended by proper selection, installation, and maintenance. Choosing the right bearing type, size, and material for the application, ensuring proper lubrication, avoiding excessive loads and speeds, and regularly inspecting and replacing worn or damaged bearings can all help to prolong bearing life.
| 5. What are some common failure modes in bearings? | |
Common failure modes in bearings include fatigue, wear, corrosion, and overheating. Fatigue failure occurs when repeated cyclic loading leads to the formation and propagation of cracks in the bearing material. Wear can result from inadequate lubrication, contamination, or excessive loads. Corrosion can occur due to moisture or chemical exposure. Overheating can lead to thermal expansion and damage to the bearing components.
