China Railway Publishing House, 2007, p. 1) established. This procedure was first formulated. Railway Locomotive wheel inspector verification proceduresScopeThe order applies to railway rolling stock wheel inspector (hereinafter referred to as the inspector) initial verification, subsequent verification And the use of checks. 2 Overview Check the thickness of the rim is mainly used for direct or indirect (such as contour method) locomotives, vehicles and EMU wheels Degrees, the tread wear depth, EMU wheel QR values or rolling stock vertical wheel flange wear, abrasion and local Tread Depression depth, rims (tire) Thickness, tread peeling length. Inspector Inspector divided locomotive wheels, vehicle car Check the wheel and the wheel EMU checker three, the structure diagram in Appendix A. Display device may be cursor and type Digital. NOTE. QR rim thickness measurement value is the point to the top of the rim at the level of the inside edge down to 2mm distance. 3 metering performance requirements 3.1 Measuring range Inspector of each measurement scale measurement range should meet the requirements of Table 1. Table 1 inspector measurement scale measurement range Unit. mm Measurements Inspector Type Measurement Range Flange thickness Check locomotive wheels 22 to 37 Check the vehicle wheels 20 to 35 EMU wheel inspector 20 to 37 Rim height Check locomotive wheels 25 to 40 Check the vehicle wheels 24 to 38 EMU wheel inspector 25 to 40 QR values EMU wheel inspector 3 to 13 Rim (hoop) Thickness Check locomotive wheels 38 to 95 Check the vehicle wheels 22 to 70 3.2 Face surface roughness Surface roughness Ra of the upper face of each inspector is 1.6μm. 3.3 scale mark width Vernier and main scale mark width of 0.12mm ~ 0.20mm, other scale marks width of 0.12mm ~ 0.25mm; variety of scale marks the difference in width should be less than 0.05mm. 3.4 vernier label side edge to the distance between the surface of the main scale marks Vernier label side edge between the main scale marks to surface distance should be no more than 0.3mm. ...... |
