This document was proposed by and is under the jurisdiction of the National Technical Committee on Metallurgical Equipment of the Standardization Administration of China (SAC/TC 409). Introduction GB/T 37400 is widely used not only in metallurgy, mining, lifting, material handling, industrial vehicles and other industries, but also in the equipment manufacturing process of engineering machinery, petrochemical, nuclear power, wind power, large aircraft, rail transit and other industries. It is an important basic process standard in the manufacturing of large and medium-sized equipment in various industries in China. GB/T 37400 classifies the main process stages in the manufacturing process of heavy machinery products, including material preparation, supporting inspection, cutting processing, assembly, painting, packaging, etc., thus constructing a relatively complete standard system, aiming to provide a basis for design, manufacturing, inspection, and acceptance for relevant production enterprises, business units, industry counterparts, and departments. GB/T 37400 consists of 18 parts. ——Part 1: Products inspection and test. The purpose is to ensure the quality of the parts of the products undertaken by each unit, and to ultimately ensure the quality of the whole machine. ——Part 2: Flame cutting parts. The purpose is to systematically supplement and improve the definition, requirements, grading, and methods of verticality and inclination tolerances, cutting surface quality, and inspection. ——Part 3: Welding parts. The purpose is to provide a reference basis for the manufacturing of steel welded parts using manual metal arc welding, gas-shield arc welding, submerged arc welding, and ammonia arc welding. ——Part 4: Iron castings. The purpose is to provide reference basis for the design and manufacturing of heavy machinery products. ——Part 5: Nonferrous metal casting. The purpose is to provide reference basis for special purposes, such as the design and manufacturing of complex structures and similar products of heavy machinery. ——Part 6: Steel castings. The purpose is to optimize the determination and retesting rules of impact absorption energy for steel castings, and improve detection accuracy. ——Part 7: Repair welding for steel castings. The purpose is to provide guidance on the repair welding process of defects in carbon steel, low alloy steel, and high manganese steel castings before precision machining. ——Part 8: Forgings. The purpose is to ensure the quality of important forgings in heavy machinery and improve the rules for retesting and judgment. ——Part 9: Machining parts. The purpose is to systematically and comprehensively propose technical requirements for machined parts. ——Part 10: Assembling. The purpose is to clarify the general technical requirements for geometric tolerances, assembly connection methods, typical component assembly, final assembly, inspection and commissioning, disassembly, etc. of assembled components. ——Part 11: Piping. The purpose is to achieve piping for oil lubrication, grease lubrication, hydraulic, pneumatic, and industrial water systems for different mechanical products. ——Part 12: Painting. The purpose is to clarify the coating technology requirements and testing requirements for heavy machinery products and their parts and components. ——Part 13: Packaging. The purpose is to clarify the packaging category, packaging materials, protection and fixation of goods, packaging requirements, and test methods for heavy machinery products. ——Part 14: Nondestructive test of steel castings. The purpose is to clarify the testing requirements for the welding repair area of steel castings, and provide users with corresponding measurement methods and acceptance requirements. ——Part 15: Nondestructive test of steel forgings.

Heavy mechanical general technical specification - Part 18: Opening gear drives system 1 Scope This document specifies the type classification, technical requirements, test methods, inspection as well as marking, packaging, transportation, storage of opening gear drives system. This document is applicable to the low-speed heavy-load involute opening gear drives systems used on cylindrical rotary equipment, such as ball mills, rod mills, autogenous mills, semi-autogenous mills, rotary kilns, cooling machines, drying machines, and drum mixers. It may serve as a reference for other rotary opening gear drives systems. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document.
