Description

Technical Field

[0001] The utility model relates to the technical field of bushings, and particularly to an adjustable bushing structure. Background Art

[0002] A bushing is an indispensable component in mechanical equipment. It plays a crucial role in the operation of the equipment with its multiple functions. By reducing the direct friction between the shaft and the hole, the bushing significantly reduces wear, extends the service life of the equipment, and reduces maintenance costs. At the same time, it also has excellent sealing performance, effectively preventing medium leakage and ensuring the stable operation of the system. In addition, the bushing can absorb and disperse vibration energy, reducing equipment vibration and noise.

[0003] The existing patent (Publication No.: CN219712064U) discloses a high-strength bushing structure, which relates to the technical field of bushings. It includes a protection module and a loading and unloading module. The protection module includes a bushing body, an annular cavity opened on the inner wall of the bushing body, two rubber half-rings movably installed inside the annular cavity, a plurality of first magnets installed on the outer sides of the rubber half-rings, a plurality of second magnets connected to the inner wall of the annular cavity, a tightening spring connected between the first magnets and the second magnets, and a wear-resistant ring detachably installed between the two tightening springs. The inventor found the following problems in the prior art that have not been well solved during the implementation of this solution: This device uses a tightening spring to achieve damping and shock absorption, with a relatively complex structure, a high vulnerability rate, and high maintenance and replacement costs. This device cannot achieve the function of adjusting to adapt to the gap, and has a small application range. Summary of the Utility Model
