| Abstract: | The pinion gear and ring gear of the carbon steel assembly in agricultural machinery are produced by investment casting with intermediate temperature wax and silica sol shell.The technical difficulties of castings,production conditions,mould design,shell making,metal smelting and pouring are discussed.The results verify that the process is reasonable and feasible,where the high quality products are produced with a low scrap rate.Such direct assembly in agricultural machinery not only can reduce the manufacturing cost,but also improve production efficiency. |
