LOW FRICTION SEALING DEVICE AND ASSOCIATED ROLLING BEARING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240052888 titled 'LOW FRICTION SEALING DEVICE AND ASSOCIATED ROLLING BEARING
Simplified Explanation
- A rolling bearing consists of inner and outer rings, rolling elements, and a sealing device. - The sealing device includes two shields, two sealing elements with sealing lips, and a channel between them. - The channel is inclined at an acute angle to the common axis of symmetry of the shields. - The first sealing element has a conical smooth lateral surface, while the second sealing element has a lateral surface with steps.
Potential Applications
- Automotive industry - Aerospace industry - Industrial machinery
Problems Solved
- Preventing contamination of rolling elements - Extending the lifespan of the bearing - Reducing maintenance requirements
Benefits
- Improved sealing performance - Enhanced durability - Reduced friction and wear
Original Abstract Submitted
a rolling bearing includes an inner ring, an outer ring, a plurality of rolling elements housed between the inner ring and the outer ring, and a sealing device. the sealing device includes a first shield connected to the inner ring, a second shield connected to the outer ring to rotate therewith, a first sealing element connected to the second shield and provided with a sealing lip contacting the first shield, and a second sealing element connected to the first shield and facing a radially outer section of the first sealing element, defining a channel therebetween inclined at an acute angle to a common axis of symmetry of the shields and delimited between a conical smooth lateral surface of the first sealing element and a lateral surface of the second sealing element arranged opposite and parallel to the first lateral surface and provided with a plurality of steps.
