Northern heavy industry successfully developed the cutting reducer of high-power roadheader

China Construction machinery information

Guide: the development task of high-power (roadheader) cutting reducer of the group wolf plan project declared by the transmission equipment branch has been successfully completed, and the contract has been successfully signed and has been successfully produced. Ebz320 roadheader this type of cutting reducer has passed the strict pressure maintaining test and loading test, and all performances

the wolf project of the group company declared by the transmission equipment branch - most of the pore sizes in the high-power (roadheader) cutting materials are nano-sized cutting reducers. The development task has been successfully completed, and the contract has been successfully signed and successfully produced

ebz320 roadheader - this type of cutting reducer has passed the strict pressure maintaining test and loading test, and all performance indexes meet the use requirements. This type of reducer adopts advanced design concept, which greatly improves the "power volume ratio" of the reducer; Through the reasonable application of SolidWorks 3D mapping software and ANSYS finite element analysis software, the research and development process has become efficient and scientific; In order to meet the main machine's function of using high-pressure water flow to assist cutting, a reducer high-pressure water flow conveying mechanism has been innovatively designed, and this new mechanism has successfully obtained the national invention patent; Adopting the transmission structure of one-stage parallel plus two-stage planets, and using the technology of multi planet load sharing, the planetary transmission system is optimized and designed; It solves the sealing problem of reducer in harsh environment. Special gbt13229 (1) 991 metal low temperature tensile test method test in terms of stretching, bending, tightening or shearing is classified according to the direction of strain initiation and the speed of force application in the template

the technical level of the high-power cutting reducer developed by the transmission equipment branch this time is internationally advanced and domestically leading, providing a solid technical support for rapid occupation and expansion of domestic and foreign markets
