农业机械产品中使用的传动件多为键联结结构，键槽加工的工作量较大，由于农业机械的传动精度一般低于通用机械，农机制造行业对孔用键槽常见的加工方法是用牛头刨床刨削加工，存在生产效率低、制造精度差、零件装配不能互换等缺点，在生产实践中我们设计制造了车床孔用键... Transmission parts used in agricultural machinery products are mostly key link structure, the key slot processing workload is large, because the transmission accuracy of agricultural machinery is generally lower than the general machinery, agricultural machinery manufacturing industry on the key groove with a common processing method is shaper planing Cutting, there is a low production efficiency, poor manufacturing accuracy, parts assembly can not be interchangeable shortcomings, in the production of our design and manufacture of the lathe hole with the key ...
