一、示值误差分析与诊断杠杆齿轮传动式千分表是通过杠杆齿轮传动 ,将测杆的直线杠位移变为指针角位移的计量器具 ,主要用于测量制作尺寸和形状、位置误差。杠杆齿轮传动式千分表示值误差形成的原因有内在和外在的 ,内因是指本身结构原理、制造精度、材质、装配等方面存在的缺 First, the error analysis and diagnosis of indication The gear-driven dial indicator through the lever gear transmission, the rod will be measured straight rod displacement into a pointer angular displacement measuring instruments, mainly for the measurement of the size and shape, position error. Lever gear-driven micrometer said the value of the reasons for the internal and external causes of error, internal refers to the principle of its own structure, manufacturing accuracy, material, assembly and other aspects of the lack
