Design And Condition Check For The Planetary Gear Reducer Of The Roadheader

EBZ240boring machine is a vertical type cantilever roadheader, this machine ismainly used for deep coal mining rock roadway mining experience, and is also suitablefor the tunnel construction. The working parts of the cutting head are connected throughthe planetary reducer motor driven power and torque transmission. Planetary reducertransmission performance, structure influence the EBZ240tunneling machine cuttingperformance, structure and size, it is EBZ240boring machine work an importantcomponent of the machine, in the EBZ240boring machine mining roadway in thewhole process that plays a central role, its efficiency directly determines the efficiencyof the complete machine.EBZ240boring machine work mechanism reserved space and workingenvironment, requirements of planetary reducer can simplify the structure, reducevolume, reduce the gear modulus, enhance the mechanical properties of. This paperpresents a EBZ240boring machine planetary speed reducer structure optimizationscheme, distribution, set up at all levels of transmission ratio and gear tooth number, onits main components were optimized design and plan. The optimized EBZ240boringmachine planetary reducer reduces the transmission of shocks, the drive to improve thestability, low noise, simple structure, convenient manufacture, installation and repair.This paper uses ANSYS to EBZ240boring machine planetary reducer optimizationstructure of the gear and the planetary frame and other major components are finiteelement static analysis. after ANSYS statics analysis shows: EBZ240boring machineplanetary reducer main component produces the strain, stress, deformation anddisplacement variation is relatively stable, the large strain, stress, deformation anddisplacement is also in its own material permissible range. Through a series ofreasonable optimization of integration and the slowdown of the mechanics analysis, pluslive2400hours without fault experiments, proves this model of the planetary speedreducer structure optimization design is reasonable.
