Description

Technical Field

[0001] This utility model relates to the field of bearing cleaning technology, specifically to an oil film bearing cleaning device. Background Technology

[0002] Oil film bearings are an important component in modern mechanical equipment; their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy.

[0003] In existing technologies, the cleaning of oil film bearings generally involves disassembling the bearing housing, placing the oil film bearing in a large water tank, adding cleaning fluid, and rinsing with running water. This method requires a large water tank area, has low cleaning efficiency, and consumes a large amount of water when using running water for cleaning.

[0004] To address this, those skilled in the art have developed a cleaning box for oil film bearings, as disclosed in CN201969707U, which improves cleaning efficiency to some extent and reduces the consumption of cleaning fluid and rinsing water. However, the aforementioned cleaning box still has the following problems to be solved: Since this cleaning box generally uses room temperature cleaning fluid, it is difficult to clean oil stains and other impurities on the bearings. Moreover, the binding effect with the cleaning agent is poor at room temperature, resulting in residual oil stains and other impurities after the bearings are cleaned, leading to poor cleaning effect. Furthermore, the design of the box cover is relatively complex, requiring counterweights to be placed on the cover to prevent tilting, making it inconvenient to open. In addition, this large, integrated, enclosed box structure is only suitable for gantry cranes to lift large bearings for cleaning. Cleaning small-sized oil film bearings is uneconomical, and the integrated enclosed structure is also not conducive to subsequent slag removal, impurity removal, and maintenance.
