Abstract
The possibility of using the multi-sensory coordinate technology for measuring the selected elements of rolling bearings is presented. The results of spherical cap of conical roller radius and angle between the main and auxiliary track of the conical bearing inner ring measurements are also presented.
Highlights
Measurement of rolling bearing components due to their specificity and tolerances requires to use appropriate measuring devices to ensure sufficient value of the measurement uncertainty
In the case of a contact profilometer, there is a risk of collision due to the geometry of the roller cap and difficulty in positioning the measuring element, so that the measurement is performed along the meridian
Following standards were used to analyze the reliability of the conical roller cap radius measurement: step standard consisting of 2 K-class reference plates with a center lengths of 3 and 4 mm, U = 0.049 μm (k = 2), bonded to interference glass plate of class I with a maximum flatness of less than 30 nm, ceramic satin reference sphere with radius R = 15.00125 mm, determined with uncertainty U = 0.3 μm (k = 2), roundness deviation RONt = 0.074 μm, roller standard – cylinder with base radius R = 40.1024 mm, determined with uncertainty U = 0.9 μm (k = 2), RONt = 0.3 μm
Summary
The paper presents the abilities of multi-sensor coordinate technique to measurements of selected components of rolling bearings. The results of spherical cap of conical roller radius and angle between the main and auxiliary track of the conical bearing inner ring measurements are presented. The development of multi-sensor coordinate measuring devices in recent years makes it possible to use them to measure rolling bearings components. Measurement of these parts using methods that are applied in hitherto practice can be difficult or troublesome [1, 3]. The paper presents abilities of multi-sensor coordinate measuring technique to measure the radius of the spherical cap of conical roller and the angle between the primary running track and the auxiliary running track of the inner ring of conical bearing
