MG400900电牵引采煤机行走部设计

AbstractMG400 900-WD shearer is a multi-motor driven AC traction shearer.The electric traction technology used by this type of shearer has powerfulfunctions.This is an outstanding performance of China's technology.Icarried out a detailed analysis of the design and research of this shearer,carried out a detailed calculation of each parameter,analyzed eachimportant component of the electric traction shearer,and then determinedeach part of the walking part,and finally Completed the selection.At the same time when the type selection is determined,the researchof the gear is started.After detailed analysis,the material selectionof the gear and the overall transmission scheme are determined,and theneach part of the transmission is designed and checked in detail.The shaftdesign and material selection are finally completed Yes,it was alsochecked.This article also introduces the daily maintenance and maintenanceof the shearer at the end,which is also the result of detailed analysis.In short,the design of this article is to make the coal mining machinemore complete,adapt to the harsh underground environment,and createbenefits that can make the company progress.It is also to be able to carryout underground work more safely.Key word:Electric haulage shearer;walking part;gear;reductionmechani sm
