The MG250/591-WD type mining machine is that a kind of electricity draws the high-power mining machine, this machine fuselage is low, Installation is large in power,all electrical machineries are fixed up horizontally, mechanical drive is all the transmission of straight tooth, electrical machinery, walk case drive wheel package etc. can take from old pool side out, so the transmission is high in efficiency, easy to install and safeguard.
Calculate in design which cuts the cutting department of main introduction mining machine of this manual. It is made up of a gearbox and moderate breeze gear wheel transmission that the MG250/591-WD type mining machine cuts the cutting department, cut the electrical machinery of cutting department and put to fix up horizontally in the rocker arm, the power that the motor outputs leans on a round of transmission of department of gear wheel and planet round via the tertiary straight tooth, urge the cylinder to rotate finally. Cut the cutting department and adopt the floating structure of four planetary forms, have reduced the physical dimension, adopt the large angle to curve the rocker arm to design, have strengthened the space of coal, have improved the coal result of putting.
In the course of designing, to cutting the axle of the cutting department, gear wheel of the transmission, parts such as the bearing and spline linking using,etc have designed to calculate, the intensity is checked and selected for use. This manual mainly designs for main part one calculating to check with the intensity have narrated and introduced.
In addition,returning use for MG250/591-WD mining machine and maintenance proves,In order to be able to good full play performance of person who should mine, reach the best working result.
