Fault Analysis and Form Discussion on Common Coupling of Coal Mining Machinery and Equipment

Abstract

By analyzing the possible faults such as wear, tooth breakage and deformation caused by couplings used in coal mine machinery and equipment, combined with practical application experience, the paper analyzes that the basic reason of causing coupling damage is the transient impact caused by overloading and design defects. In order to protect mechanical equipment from damage or shutdown caused by coupling failure such as overload and deformation, the advantages and disadvantages of rigid coupling, flexible coupling and safety coupling are compared, the author analyzes several kinds of couplings commonly used in coal mine machinery equipment, as well as the practical application occasions of various couplings, including the factors to be considered in the process of design and selection, etc., this paper provides a reference for the selection and design of couplings of coal mine machinery, and also provides ideas for the selection and design of couplings of non-coal mining machinery and other practical applications.
