The design of a new gearbox for a coal shearer is developed. The authors developed and implemented a technology of gear manufacturing from new steels 18Х2Н4МАА and 38ХН3МФАА, providing the increase of gear’s life time. Research and bench tests of a gearbox for mining combine confirmed the benefits of design, technological solutions and new steels.
