Abstract
Electric traction machine has a high degree of mechatronics, increasing the installed power, speed, and doubled traction control system of energy saving, high transmission efficiency.
The design of the coal mining machine is suitable for use in thick coal seam no chain electric haulage shearer main content, design for electric haulage shearer traction of structure design, drawing speed for 0 ~ 7m/s, motor adopts horizontal layout, through the second straight tooth ary reducer with pleted. Content: the first is in different parison analysis and determination, followed by each structure size of design calculation, and finally to gear and the intensity of the transmission design and calculation results and meet the design requirements.
Keywords: coal winning machine, Electric traction, Traction,
