Abstract
Description
Technical Field
[0001] This utility model belongs to the field of casting machine equipment maintenance technology, specifically, it relates to a device for disassembling a spherical bearing. Background Technology
[0002] During operation, the casting machine's ladle platform requires frequent rotation and lifting movements to achieve precise positioning and conveying of molten metal. The ladle arm's spherical bearings must bear the weight of the ladle arm itself and the enormous load of the molten metal it carries. Because the molten metal reaches extremely high temperatures, often exceeding 1000 degrees Celsius, the environment in which the ladle arm's spherical bearings operate is extremely harsh. High temperatures not only cause the lubricating oil inside the bearing to rapidly deteriorate and fail, reducing lubrication effectiveness and increasing bearing friction and wear, but also alter the physical properties of the bearing materials, such as decreasing hardness and thermal expansion, further affecting the bearing's normal operation.
[0003] Over time, wear is inevitable in spherical bearings. Wear primarily occurs at contact points such as between the rolling elements and raceways, and between the cage and rolling elements. Even slight wear can cause noise and vibration during bearing operation, affecting the smoothness of equipment operation. As wear intensifies, the bearing clearance gradually increases, reducing the accuracy of the bearing's movement and hindering its ability to accurately receive and transfer molten metal, thus impacting product quality and production efficiency.
[0004] When the spherical bearings of the casting arm show wear or failure, they need to be replaced promptly to ensure the normal operation of the casting machine's large casting platform. Due to the lack of effective lifting and securing methods, maintenance personnel need to perform numerous auxiliary operations when replacing the bearings. Under traditional replacement methods, the lifting and securing of the casting arm is unstable, posing significant safety hazards. If the casting arm accidentally falls during replacement, it can cause serious bodily injury to maintenance personnel working on the job, and even endanger their lives. Furthermore, a falling casting arm can also damage surrounding equipment, causing serious accidents such as fires and explosions, resulting in huge economic losses and social impact for the company.
[0005] In view of this, this utility model is proposed. Utility Model Content
