hello sir... your teaching techniques is very excellent .. so different from others... keep it up sir👍 Pls make the next lessons...
  1. BEARINGS An Overview Presentation by: Karthik Balaji Keshavamurthi


  2. What is a Bearing? . A machine component - Found in areas of relative motion Enables frictionless rotation of a shaft about a hole


  3. Functions Minimum Friction in rotation - Support for the shafts. Transmits forces from shaft to the housing Used to connect a rotary part to a stationary part.


  4. TYPES OF BEARINGS Plain Bearings or Journal Bearings (uses sliding friction) Load Load Load High-Pressure Area Shaft at Rest) High-Pressure Area (Shaft Starting to Rotate) High-Pressure Area (Shat at Full Speed Rolling Contact Bearing (Reduces rolling friction)


  5. Applications of Journal Bearing Crankshaft Bearings - Centrifugal Pumps .Electric Motors -Steam and Gas Turbines Rod Journals Main Journals Rope Conveyors


  6. Applications of Roller bearings . Machine Tool Spindles Automobile Axles - Gear Boxes -Crane Hooks


  7. Upcoming Topic:s Types of Roller bearings Load Life Relationship . Selection of Roller Bearings Sliding Contact Bearings . Sample Gate Questions


  8. THANK YOU
