The link chain is widely used in mining and transportation equipment, which is the core of the normal operation of the whole equipment. Therefore, the processing quality of the link ring will directly affect the production effect, so the quality requirements will become more and more strict!
The link ring is the connecting part on the scraper chain of the coal mine scraper conveyor. It plays an important role in the traction link, so it is necessary to control the various procedures to create a perfect link. The link ring consists of two identical shrimp-shaped half rings and one stable pin. The shrimp-shaped half ring is provided with two types of convex and concave tooth systems, and the tooth shape in each tooth system is provided with convex and concave arcs, and each tooth direction also has a circular arc. The two shrimp-shaped half rings are tensioned by the convex and concave teeth and are fixed together by the stabilizing pins. Due to its unique structure, it is determined to have superior tensile, torsional, flexural and fatigue resistance. The two concave and convex teeth on the shrimp-shaped half ring are provided with arcs in both directions, and each tooth system has high precision, so it is difficult to process. At the same time, due to its high strength requirements, the requirements for heat treatment are also high. The link ring has a high breaking capacity and requires high reliability in operation. Therefore, it is also an urgent technical requirement to study the stress of the link and improve the life of the link. We can also use the theory of elastic contact and deformation coordination to study the contact force and deformation of the pin and the link. The mining arc, ladder teeth, and flat chain link are analyzed under the condition of maximum tensile force, and the force received by the link ring is calculated, and the force of the link ring is analyzed. The design of the docking link structure is optimized by specifying design parameters.
