QIBR self-aligning ball bearings with extended inner rings have solved many key problems in various fields, which are mainly reflected in the following aspects:
1. Automatic self-aligning function
The biggest feature of QIBR self-aligning ball bearings with extended inner rings is that they can automatically align. Because the relative position of the raceways of the inner and outer rings has a certain angle (that is, the raceway of the outer ring is spherical). When the shaft or bearing seat is relatively offset, the contact surface of the ball and the raceway will automatically adjust to ensure that the bearing keeps stable working state and reduce the wear caused by angle errors.
2. Carrying capacity
QIBR self-aligning ball bearings with extended inner rings have relatively strong carrying capacity. It can withstand certain radial loads and axial loads.
3. Strong adaptability
QIBR self-aligning ball bearings with extended inner rings are particularly suitable for occasions where there is axial offset during the process of installation due to their self-aligning characteristics. For example, the bending of the shaft, improper installation of the bearing seat, etc., these situations may cause angular deviation of the bearing, but the self-aligning ball bearing can effectively compensate for these problems and maintain smooth operation.
4. Structural features
QIBR self-aligning ball bearings with extended inner rings are double-row designs with two-row ball cages, which can withstand large radial loads.
The performance improvement and solutions of QIBR self-aligning ball bearings with extended inner ring
1. Lubricant optimization: Choose appropriate lubricating oil or grease, and make appropriate additions and blends to reduce friction and improve wear resistance. The usage of synthetic lubricants or nano-lubricants can significantly improve the efficiency and life of bearings.
2. Raceway optimization: Optimize the raceway geometry of the inner and outer rings, such as increasing the raceway accuracy, improving surface finish, reducing friction, and reducing energy loss, thereby improving the operating efficiency of the bearing.
3. Improve quality of rolling element: Reduce friction and wear by improving the surface finish and hardness of the rolling elements. The usage of high-precision rolling elements (such as ceramics) can significantly improve the running performance of the bearing.
4. The optimization of cage design: Adopt a more optimized cage structure, such as using high temperature resistant and corrosion resistant materials and designs, to improve the durability of the cage and the stability of the bearing.
Main application areas of QIBR self-aligning ball bearings with extended inner ring
Railway vehicle bearings: In railway vehicles, self-aligning ball bearings can cope with problems such as uneven tracks and wheel deviation, ensuring the smoothness and reliability of vehicle operation.
Food machinery: such as mixers, packaging machines, conveyor belts and other equipments, self-aligning ball bearings can adapt to the shaft deviation problems caused by vibration and load changes during the process of operation of the equipment, ensuring stable operation of the equipments.
Wheel bearings: Wheel bearings are often subject to high-speed rotation and irregular loads. Self-aligning ball bearings in wheel systems can better adapt to axle misalignment or offset problems, reduce wear, and improve performance and durability.
Transmission equipment: In some mechanical transmission systems, self-aligning ball bearings can effectively alleviate problems caused by uneven loads or shaft misalignment.
