农机维修时,常进行拆卸和安装,而农机的类型、牌号很多,构造不一,若乱拆硬装,就容易损坏农机。因此,在拆卸和安装时,应严格按规程进行。1.拆卸。应按农机构造的不同,预先考虑好操作程序,以免先后倒置。拆卸时,应从外到内、从上到下进行。操作时应使用专用工具,禁止用锤子直接在零件上敲击。要弄清零件的回松方向,对精密零件宜小心操作,如丝杆长轴零件须用绳索吊起,用布包好,以防弯曲变形和损坏。拆下的零部件,应按要求依次放置于木架上、木箱或零件盘内,不得置于地上,以防碰坏、锈蚀。拆下的零件应尽量按原结构套在一
Agricultural machinery maintenance, often for disassembly and installation, and the type of agricultural machinery, many brands, different structures, if the disassembled hardcover, it is easy to damage agricultural machinery. Therefore, in the demolition and installation, should be strictly in accordance with the rules. Disassemble Should be based on the construction of different agricultural institutions, pre-considered good operating procedures, so as not to have inverted. Disassembly, from outside to inside, from top to bottom. Operation should use special tools, prohibit the hammer directly on the parts percussion. To understand the direction of the back of loose parts, the precision parts should be careful operation, such as the long axis of the screw rod to be hoisted with a piece of cloth, to prevent bending deformation and damage. Remove the parts, according to the requirements should be placed on the wooden frame, wooden box or parts plate, shall not be placed on the ground, to prevent collision damage, corrosion. Remove the parts should be as far as possible in accordance with the original structure in one
