摘要:The article presents the modeling of cam drive mechanism of rotary table with periodic motion for products delivery to the feed zone of a screen printing press, conducted using the modern computer software.The author selected basic parameters of the mechanism, calculated the size of the radius vector of variable cam profile and appropriate racing rotary angles. Using the calculated data, in the program Autodesk Inventor cam profile was built and three dimensional cam itself was created, and the other elements of the mechanism were created: base, cylindrical gear which wheel acts as yoke disk, rollers, driven shaft. To load the mechanism, driving link was created as a rotary table of screen printing press with four positions for mounting products. A cam mechanism assembly was created with overlap of the necessary links between elements. According to the power parameters of a table, calculation was conducted, processing of the values was carried out and compared with values used for the calculations. It was determined that the deviation of data obtained as a result of modeling compared to the theoretical data is within acceptable limits at 1.3 %. Thus, the conducted simulation of a cam mechanism with periodic rotation using the new automated design program Autodesk Inventor Simulation allowed to confirm the workability of the proposed method of calculation and the correctness of the theoretical principles and adopted assumptions.
其他摘要:У статті проведено моделювання засобами комп’ютерного середовища Autodesk Inventor з метою підтвердження проведених аналітичних досліджень параметрів кулачкового механізму приводу поворотного столу подавання виробів у зону друку тамподрукарської машини, який перетворює обертальний рух постійної швидкості у періодичний обертальний рух, який описується диференціальним законом.
