摘　　要：ZD6系列电动转辙机锁闭齿轮为不完全齿轮,不能按照标准齿轮的计算方法确定锁闭齿轮几何参数,无法使用三坐标测量仪或者齿轮测量仪测量锁闭齿轮齿形参数。为此,采用仿形法,利用锁闭齿轮参数,在计算机辅助制造软件中模拟加工过程,生成齿形铣刀廓形曲线。通过测量齿形铣刀廓形坐标,生成锁闭齿轮齿形图。提出采用锁闭齿轮齿高度和弦齿厚度,作为控制ZD6系列电动转辙机锁闭齿轮全齿和半齿齿形质量的参数。这些参数已经在ZD6系列电动转辙机实际生产中得到推广应用。The locking gear for ZD6 series electric switch machine is incomplete gear.The geometric parameters of locking gear cannot be determined according to the calculation method of standard gear.Neither three coordinate measuring instrument nor gear measuring instrument can be used to measure the tooth profile parameters of locking gear.Therefore,by using the profile modeling method and the parameters of the locking gear,the machining process was simulated in the computer aided manufacturing software to generate the profile curve of the tooth profile cutter.The profile diagram of the locking gear is generated by measuring the profile coordinates of the tooth profile cutter.The tooth height and tooth thickness of the locking gear are used as parameters to control the shape quality of the full teeth and half teeth of the locking gear for ZD6 series electric switch.These parameters have been popularized and applied in the actual production of ZD6 series electric switch machine.
