Tolerance of measurement
Measurement of the hole
Measurement of inner diameter
Inspection, the cover and base bolt, and then, including Kong and Central by two measuring method.
And inner cylindrical bore hole measuring vertical face
bore cylindrical holes by two measurements, including the full width of the different sections and angular position measurements. Cylindrical t = Dasmax-Dasmin.
Vertical face bore the measurement: the standard parts into the bearing, the base and then cover and bolt positioning (not tight), were measured with a feeler standard parts bearing bore face and shoulder clearance at both ends , the maximum gap value and the minimum gap value of the degree of deviation of the vertical face.
Center high measurement
center height Hs of the measurement (see Figure 2)
Measurement, place the base of the bearing platform, with a height measuring instrument measuring bearing bore bottom contour and the actual distance between the platform surface, according to equation (1) calculate the actual center of high Hs:
Hs = H3s + Das / 2
