实验3齿轮周节偏差与周节累积误差的测量Word文档格式.docx

1、3、数据处理：（1）由相对，依次求出累积周节相对偏差上面相对（n为齿序）。（2）求相对周节偏差平均值； （3-1） （3）周节偏差 （3-2） 取中绝对值最大者作为被测齿轮的周节偏差。（4）周节累积误差 （3-3）取中绝对值最大的正负二数的绝对值之和作为周节累积误差。（5）做出合格性判断。五、被测对象 图3.3 被测对象齿轮基本参数见表1-1。模数m齿数Z压力角齿轮精度3182012单个齿距偏差（um）66.0齿距累积总偏差168.0 表3-1 齿轮基本参数表六、被测数据记录员：刘自成表3-2 第一次测量数据序号相对周节偏差读数值（um）周节偏差周节累积误差1-281.12136-145.1-
