Technical Field

[0001] The utility model relates to the technical field of flange bearings, in particular to an aluminum-magnesium alloy flange bearing with strong load-bearing capacity. Background Art

[0002] Flange bearings are generally used in high-precision instruments and equipment such as fax machines or printers, making axial positioning simple; the biggest feature is that the flange and the bearing are integrated, and generally no bearing seat or other equipment is required to fix the flange bearing. However, the existing flange bearings have some shortcomings, such as:

[0003] Application number: CN202321332287.9 ​​is a silent flange bearing. The device is equipped with multiple groups of sound insulation cotton covering the main body at the outer end of the bearing structure, so that the device will not produce large noise during operation, thereby reducing the impact of noise on the environment. However, during use, since the device is not equipped with a self-supporting mechanism, the device may have insufficient bearing capacity when connected to heavier equipment, resulting in the ball and inner ring fitting together, causing the ball to wear, reducing the sliding performance of the device during use.

When the object rotates, the first inner ring 2 will slide under the drive of the first ball block 3, and the first inner ring 2 will also drive the rotating ring 7 to rotate, so that the rotating ring 7 drives the second inner ring 9 to rotate, so that the first inner ring 2 and the second inner ring 9 rotate at the same time, and at this time the first ball block 3 and the second ball block 10 will also slide at the same time, thereby increasing the sliding property of the device;

[0043] When the first bearing mechanism is performing pressure relief work, the first outer ring 1 will disperse the pressure to the support seat 4, so that the support seat 4 disperses the pressure to the fixing bolt 5, so that the fixing bolt 5 transmits the pressure to the fixing ring 11 and the support damper 12, so that the support damper 12 relieves the pressure on the first bearing mechanism and transmits the pressure to the support ring 13, so that the device can effectively carry the load when connected to an overweight object.
