Design and Optimization Analysis of Flexible Shaft of Coal Winning Machine
WU Lei
Abstract：In order to protect the rocker gear system of the coal winning machine,improve the service life of the flexible shaft of the coal winning machine,and avoid its frequent damage,the stress distribution of the two flexible shafts of the arc structure unloading groove and the U-shaped unloading groove was analyzed by using the finite element method,and the arc structure was more suitable for the flexible shaft unloading groove structure.In addition,the control variable method was used to study the stress distribution and change law of the flexible shaft under different radius and different torques,and it was found that the smaller the radius was,the more obvious the stress concentration phenomenon at the position of the unloading groove was,and with the increase of torque was,the smaller the radius of the unloading groove was,the faster the stress growth rate was,and finally determined the optimal design parameters and provided guiding opinions for the design of the flexible shaft.
