大型直齿圆柱齿轮误差测量系统研究

针对大型齿轮在机测量存在必须停止加工过程，影响加工效率和经济效益的问题，研制了一种大型直齿圆柱齿轮离线自动测量系统．测量系统以PC为控制中心，可根据用户选择自动生成测量路径；其选用高精度测头和光栅尺，利用数控系统驱动x,y、Z轴及旋转载物台，可以实现测量位置的精确定位；可以实现齿形误差、齿距误差和齿向误差的自动测量．

Research on Large Involute Spur Gear Error Measuring System

On-line detection is by far the most common gear measurement technology, but the gear cutting process must be stopped during the measuring, which influences the efficiency of gear-making machine and the enterprise＇s economic benefit. To solve this problem, a large involute spur gear error measuring system was developed. Using computer as control center, probe sensor to collect data, x-y-z displacement platform and rotating stage to achieve the exact location of the mathematical point, the new system can make the large gear error measurement come true. Meanwhile the measurement system can also realize the automatic measurement of tooth profile, circular pitch and helix deviation.
