The MG700-WD mining machine is a kind of electricity drawing and high-power mining machine, this machine’s fuselage is low, installation-power is large, all electric motor are fixed up horizontally, mechanical drive is all the transmission of gear, electric motor、walking case drive wheel package etc, can take from old pool side out, so the transmission is high in efficiency, easy to install and maintain.
This manual main introduces the calculation of the cutting department of mining machine in design. The MG700-WD mining machine is made up of four level gear transmission, the electric motor of the cutting department is horizontally placed the inner of swinging arm, the output power of electric motor is drived by three level gear transmission and the department of planet, than drive the drum. The cutting department adopts the floating structure of four planetary forms, have reduced the physical dimension, adopts the large angle curve swinging arm design, have expanded the space of coal and bringed about a striking effect.
In the course of designing, to the axle of the cutting department, gear wheel of the transmission, parts such as the bearing and integral key etc, have been designed and calculated, the intensity is checked and selected for use. This manual mainly narrated and introduced the designs, calculation and intensity checking of main parts.
In addition, in order to be able to good full play performance of mining machine, reach the best working result, this manual have introduced the MG700-WD mining machine’s maintenance and use,.
