Experimental findings confirm the vibrational nature of hinge wear in mining machines, suggesting design upgrades.
The authors of the article propose to improve the design of articulated units of mining loading and delivery machines with an articulated frame on the example of a hinge assembly for attaching a hydraulic cylinder rod to the front half frame. They presented the results of research on the wear of the hinge assembly under operating conditions in underground mines. They experimentally confirmed the hypothesis about the vibrational nature of the dismantling of a worn hinge assembly. They proposed a technical solution to improve the design of the hinge assembly. It allows you to increase the protection of the hinge from external dust and dirt. This makes it possible to ensure the operability of the hinge assembly.
