ABSTRACT
On the basis of analyses of the present roof bolter’s structures, the pneumatic roof bolter with vane motor was proposed and researched. Structure principle of MFT-80Y type pneumatic roof bolter with vane motor was expounded. A new project of the rotary shearing mechanism with integrating pneumatic vane motor with epicyclic reduction gear unit was carried out. The mathematical model for optimum design of the rotary shearing mechanism was set up, and the optimum design for the rotary shearing mechanism was made by MATLAB optimization toolbox. Finally, performance of MFT-80 type roof bolter made with optimum method and the on site experiment were introduced.
