Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and more specifically, it relates to a balanced support bearing. Background Technology

[0002] As a core component in the mechanical industry, bearings function to convert the sliding friction between the rotating shaft and the bearing seat into rolling friction, thereby significantly reducing friction loss and ensuring the stable operation of the mechanical system. However, the rotor is prone to generating unbalanced inertial forces when rotating at high speed, which can cause equipment vibration, noise and other problems. This not only reduces machining accuracy and product quality, but also aggravates internal wear of the bearing. Therefore, a balanced support bearing is needed to maintain the normal use of the bearing.

[0003] For example, application number 202323329757.9 discloses a balanced support bearing, including an outer ring, rolling elements inside the outer ring, a cage movably connected to the outer wall of the rolling elements, and an inner ring inside the rolling elements. The cage separates the rolling elements to reduce frictional heat generated by the bearing, ensuring the rolling elements are evenly spaced to optimize load distribution. A sealing ring is provided on the outer ring to seal the rolling elements and the cage. In this invention, by creating a stop groove on the outer ring, the rolling elements and cage can be installed into the bearing without tools. Simultaneously, the sealing ring seals the installed rolling elements and cage. This bearing is easy to install and disassemble, facilitating bearing maintenance and improving the bearing's balance and support capacity.

[0004] Based on existing technology, it has been found that existing bearings are prone to rotor imbalance under high-speed rotation conditions. Due to the uneven distribution of imbalance forces on both sides of the bearing axis during the imbalance process, and the lack of a suitable and precise adjustment structure, it is difficult for the bearing to achieve efficient and precise balance adjustment, which in turn affects its ease of assembly and use as well as the overall stability of the machine operation. Utility Model Content

When an imbalance is detected on one side of the bearing, the inner adjusting screw can be rotated by inserting an external tool into the adjustment groove, driving the inner moving block to slide along the adjustment groove, thereby precisely adjusting the radial position of the balance ball and realizing the directional correction of the imbalance force on one side. At the same time, the hemispherical groove on the inner moving block is in close contact with the balance ball to ensure the stability of the balance ball position during the adjustment process, which facilitates the balance adjustment of the bearing.
