2PGCS-710×2750Graded Crusher Critical Manufacturing Components Analysis And Study Of The Assembly

Modern coal industry rapid development both at home and abroad, ore reduction is an important part in coal preparation link, the crusher are common equipment used in the coal preparation link, but too aging now use the broken equipment control granularity, high energy consumption, low efficiency, dust control is not ideal. so this paper, taking huainan kaisheng heavy industry company project new type of2PGCS-710×2750type classification the development of the crusher is given priority to, mainly summarizes the study of the following aspects.In view of the coal production industry using the crusher defects and problems, put forward2PGCS-710×2750type classification crusher development significance, analyzed the working principle of the crusher, and the characteristics of the machine, and stress analysis was carried out on the crusher working parts. According to the above2PGCS-710×2750type classification crusher analysis, participate in designing the shape of the crusher roller tooth shape and the roller tooth arrangement, and process analysis was carried out on the main working parts;And has carried on the related drive device, transmission device design calculation and selection of working performance theory, which provides the theoretical basis of design model selection of crusher.According to a series of working parameters and size parameters using Auto CAD for crusher,2D drawings in Soild Works software crusher main working parts3D model is set up, for subsequent virtual assembly and static stress analysis laid a foundation.Using SoildWorks software assembly function was carried out on the3D model of crusher computer virtual assembly, this can save a lot of manpower, material resources, financial cost, convenient to verify the feasibility of virtual assembly process, and according to the virtual assembly process tracking crusher field assembly, the resulting object crusher machine. Finally, Application SoildWorks simulation software for the design of crusher static stress analysis, the main working parts are affected by load cases results of the stress distribution and deformation of parts;Verify that the design meets the design requirements of crusher working parts.In this paper, design of new type2PGCS-710×2750graded crusher with double toothed roll crushing, double motor drive, double insurance device (hydraulic coupling and electric control system of insurance device), automatic lubrication system, toothed roller graded crusher has high crushing strength, strict guarantee product particle size and grade of crushing double function, large capacity, small amount of pulverized coal, the whole machine has high reliability, simple structure, low power consumption.
