Abstract:

According to the original parameters of 40KW scraper conveyor and mine safety requirements and standards, permanent magnet coupler in coal mines is designed. The type of structure is standard type. The range of output torque is calculated with the design requirements. The material of permanent magnet selectes NdFeB N45SH. Combined with experimental data, the structural parameters of prototype and the overall design calculations are completed and finished. This paper also discusses the program of overload protection and the checking process of transmission shaft.

Key words: permanent magnet coupler, torque, overload protection, transmission shaft
