其次，在擦伤最深处的圆周方向上移动第四种检查器到车轮踏面无擦伤位置进行测量（不少于3次）取平均值。Secondly,thefourthcheckerismovedinthecirculardirectionofthedeepestabrasiontothenon-abrasionpositionofthewheeltreadformeasurement(notlessthan3times)toobtaintheaveragevalue.两者的差值就是擦伤深度。Thedifferencebetweenthemisthedepthoftheabrasion.8.踏面擦伤或剥离长度的测量。用轮辋厚度测尺的外刻线，沿车轮圆周方向测量擦伤部位的长度，即为踏面擦伤长度。8.Measurementoftreadabrasion/strippinglength.Measurethelengthofthescuffedareaalongthecircumferenceofthewheelusingtheouterscribelineoftherimthicknessgauge,i.e.,thelengthofthetreadscuff.9.车轮外侧碾宽的测量。将踏面圆周磨耗尺框推向右侧，使踏面圆周磨耗测尺的测头贴靠(或指向)车轮外。用平尺接触轮辋外侧面，车轮外侧碾宽数值即为踏面圆周磨耗测尺3测头对应的刻度线。9.Measurementofouterwheelwidth.Pushtheframeofthetreadcircumferentialabrasiongaugetotheright,sothattheprobeofthetreadcircumferentialabrasiongaugeiscloseto(orpointingto)theoutsideofthewheel.Contacttheoutersideoftherimwithaflatruler,thevalueoftheoutergrindingwidthofthewheelisthetreadcircumferentialwearmeasuringtape3probecorrespondingtothescaleline.二、车轮直径检查尺Wheeldiameterinspectionruler尺架右主尺左主尺左定位板固定测头左尺框右主尺右定位板固定测头螺母二、车轮直径检查尺Wheeldiameterinspectionruler同一车轮须检查3次，其最大与最小之差，即为车轮直径差。Thesamewheelshallbeinspectedthreetimes,andthedifferencebetweenitsmaximumandminimumshallbethedifferenceinwheeldiameter.三、轮对内测距离检查尺

Wheelsetinternalmeasurementdistancecheckingruler将定位钩放在车轮轮缘上,将轮对内距尺的固定测头和活动测头靠在被测车轮内侧,摆动轮对内矩尺活动测头,寻找读数拐点,即读数最小值，当读数为最小值时,该读数即为被测轮对内侧距离。测量时，需沿车轮圆周方向每120度测一次，共测量3次。Placethepositioninghookonthewheelrim,thefixedprobeandmovableprobeofthewheelsetinnerdistanceruleragainsttheinsideofthemeasuredwheel,swingthemovableprobeofthewheelsetinnermomentrulertofindtheinflectionpointofthereading,i.e.,thereadingoftheminimumvalue,whenthereadingistheminimumvalue,thereadingthatisthedistanceoftheinsideofthewheelsetbeingmeasu
