1. tapered angle deviation detection method
Taper of the tapered roller angular deviation to use dedicated roller angle measuring instrument for measurements. Measurements will be tested when compared with the standard angle of roller, tapered angle deviation of the diameter measured by the change in angular deviation.
2. Benchmark end-shape detection method
Base end of the tapered roller surface shape measurement of surface profile measuring instrument, also standard models can be used to compare tests.
3. Detection method of chamfer
Chamfer angle of tapered rollers check Board for examination.
4. Detection of roller shape and bulging line method
Measuring roller generatrix shaped or convex roller, roller when you pull out, place the rollers being measured on the instrument, adjusting the rollers, roller generatrix at both ends at the same horizontal position, adjust the probe, leave the probe in the axial plane and a vertical roller in plain line being measured. In the entire effect line except for chamfer range measurement, the measured effect of trajectory line shape, the measured difference between the displacements of the Prime cable on both ends and the Middle protruding.
