回转窑筒体垫板和齿轮外径测量控制方法的探讨

Discussion on Control Methods for Measurement of Gear Outer Diameterand Cushion Plate of Rotary Kiln

分析了采用π尺直接测量回转窑垫板、齿轮外径的误差产生原因,提出了消除测量误差的控制方法和验证方法。结果显示,采用π尺直接测量垫板外径和小齿轮齿顶圆直径的误差较大,测量示值均小于实际尺寸;采用π尺直接测量垫板外径和齿轮顶圆直径须考虑测量误差补偿;根据相关理论尺寸可以推算“测量误差补偿值”,并应进行相应操作验证。

The causes of errors were analyzed when the outer diameter of gears and cushion plate for rotary kiln were measured to use π ruler in directly,and the control and verification methods for eliminating measurement errors were proposed.The results showed that the errors were bigger which were measured directly for the outer diameter of the shim plate and the diameter of the pinion tooth top circle usingπruler,and the measured values were less than the actual size.The measurement errors must be considered when theπruler was used to measure directly the outer diameter of the pad plate and the diameter of the pinion tip circle compensation.The measurement errors compensation value could be calculated according to relevant theoretical dimensions,and the corresponding operation verification should be performed.
