齿轮齿条在使用过程中,齿面发生磨损,其原因是由于齿条一般都没有经过淬火,硬度低,磨损尤其严重。通常是局部磨损,磨损表面很粗糙,光洁度不好,磨损形式如图1所示。磨损最严重的地方是齿条经常使用的一段。从使用情况来看,如果使用在机床的走刀机构,加工的零件表面光洁度不好,一般表现出齿轮与齿条啮合不平稳,会加快齿条的磨损,因此必须及时进行修复。SK12立车刀架齿条属于重型齿条,重量大、体积大,重新制造所需的材料工时都多,而且制造的难度较大,同时齿条的其他部分又比较完好,报废重作很不经济,进行 Rack and pinion in use, the tooth surface wear occurs, the reason is because the rack is generally not quenched, low hardness, wear and tear is particularly serious. Usually local wear and tear, wear the surface is rough, poor finish, wear form shown in Figure 1. The most worn place is often used rack section. From the use of the situation, if the use of the machine tool body, the machined parts surface finish is poor, the general performance of the gear and rack engagement is not smooth, will speed up the rack wear and tear, it must be promptly repaired. SK12 vertical lathe rack rack is a heavy rack, heavy, bulky, remanufactured materials required for many hours and more difficult to manufacture, while the rest of the rack is relatively good, scrapped very much Economic, carry out
