Research on the Structural Improvement and Optimisation Design of Intermediate Shaft Device of Coal Mine Hoisting Winch
JC-300 winch is suitable for many working conditions,especially widely used in coal mines,the winch can be dispatched to load and unload coal materials,but also can be used to carry heavy loads.However,due to the intermediate shaft of JC-300 winch carries a large moment,the deviation of the manufacturing process leads to the determination of the tolerance fit size,in the process of meshing is prone to over-topping phenomenon between the slider and the intermediate shaft pinion,so that the slider jammed,and the intermediate shaft pinion can't rotate normally.Based on the actual problems occurring in the project,it is proposed to increase the guide wheel in the intermediate shaft pinion and slider of the winch respectively,and after the feasibility analysis of the programme,the strength analysis of the guide wheel shaft is carried out by using ansys software.The research results show the reasonableness of the design improvement and provide a basis for the optimisation design of the winch intermediate shaft structure.
