Research on Parametric Design of Torsion Shaft of Coal Mining machine
In order to improve the reliability of the torque shaft of the coal mining machine,through the simulation analysis of the torque shaft,respectively,from the static mechanics and dynamics of the two aspects of the torque shaft stress changes,and found that in 1 times the rated power of the motor,the torque of the large shear stress of 304.07 MPa and 610.5 MPa,at this time the torque shaft to play the role of overload protection.At the same time,the static mechanical characteristics and fatigue characteristics of the torque shaft are analysed under different unloading groove radii,and it is found that the optimal unloading groove radius is 24 mm,and at this time,the torque shaft is able to overcome the fatigue damage of the material to meet the normal operation.
