T/DGGC 009-2020 Full-face Tunnel Boring Machine Remanufacturing with Reducer
Abstract
This standard specifies the remanufacturing inspection and evaluation of reducers for full-face tunnel boring machines (hereinafter referred to as reducers), the formulation of remanufacturing plans, remanufacturing design, disassembly and cleaning, parts inspection and evaluation, remanufacturing processing, remanufacturing assembly and debugging, acceptance, marking and storage, and safety and environmental protection requirements. This standard applies to waste/used reducers that meet the following conditions: -- The maximum speed of the high-speed shaft does not exceed 2,500 r/min; -- The gear linear velocity does not exceed 20 m/s; -- The working environment temperature is -40℃~+45℃.
