Motion Analyse And Strength Research Of Drive System In Bread Cabin

According to modern war "sweeping require" and "mechanization demand", our army develop the SO3-field operations bread machining cabin. This equipment is mobile container, and have the ability to produce2400pieces of breads per hour. As the transmission and transportation system, roller chain play a important role in the bread cabin.This topic comprises of the following parts:1) Explain the bread machining cabin all over the world briefly.2) Survey the present development and trend of the chain all over the world, including chain products and chain technologies.3) Explain the basic transmission theory, mesh characters, chain types and the main transmission models briefly, analyze the existent problems, and propose some means to improve the chain products’ capability and performance.4) The present method applied in calculating the power transmission between the chain products has been not about vertical roller chain. Author presented a suite of functions to calculate the stress of vertical roller chain by comparing of two methods5) Calculate the stress of the chain plate, shaft plug and sleeve while being loaded via the functions of stress and displacement theory, get the contact stress value between the shaft plug and sleeve parts from the elastic mechanical theory.6) Bring forward a real model:bread machining cabin. Use ANSYS8.0to build a3-D model according with FEA theory. Analyze the displacement of the chain plates (including outer and inner), shaft plug, and sleeve parts. Analyze the contact strength of the shaft plug and sleeve parts. 7) compare the results of the theory with that of FEA analysis.8) Experiment study the roller chain efficiency in the different conditions, just as grease lubrication, water lubrication and without lubrication.
