| Thin coal seam of drum shearer is ver y important to assure high production and efficienc y in coal mine production.Traction is an important part of coal winning machine,its performance determines the adaptability,reliability and stability of the drum shearer.Due to the limitation of coal thickness,in narrow working space,the design could satisf y the requirement of working drawing department is a must to solve the problem,based on the modern design method,the optimization of traction performance parameters,the final design of thin coal seam traction with large module and large gear ratio traction drives and walking wheel traction institutions.Meet the requirements of the coal mining machine of traction.In this paper,a coal mining working face in coal seam occurrence condition and the production requirements as the basis,design the overall parameters of shearer;According to the principle of form a complete set of these compressors,determine the shape of the traction part size,transmission system,the related parameters in the traction drive shaft,the gear ratio distribution,discussed the transmission form and traction drive arrangement,introduces the function and design method of traction of accessor y device;Then the drive gear and bearing of traction drive force analysis and intensity;And the shape of the transmission device the smallest size of the largest planetar y transmission mechanism as the optimization goal,optimization design was carried out,using the least function in MATLAB to solve,finally determine the related parameters of the traction drive device;Using three dimensional software walking drive finite element model is established,and the stress of the most complex walk round into the finite element design.Finall y solved within the limited space,large transmission ratio of shearer walking device design problems.According to the requirements of national standards,the use of professional experiment platform on the traction part,and through the real-time monitoring s ystem for monitoring and real-time collected test data,test process b y analyzing test data,the design of the traction drive high efficienc y,stable,reliable operation and through the thin coal seam of drum shearer machine test;Through the whole industrial test,verif ying the rationality of the traction part design and meet the performance requirements of coal winning machine work. |
