Detection and judgment method for included angle between inner ring conical rolling path and large flange

Abstract

Disclosed is a detection and judgment method for an included angle between an inner ring conical rolling path and a large flange. A block gauge (10) is padded under a stand column (14); the height of the block gauge is L1 sin beta; beta is an included angle between the large flange and an inner ring end face; L1 is spacing between a rotating shaft (15) and the stand column; an elastic hinge device (11) is positioned on the stand column through a bolt; an inner ring (12) is flatwise arranged on the elastic hinge device; the large flange is theoretically parallel to a guide rail (9) and a design included angle between the large flange and a conical outer rolling path is equal to omega; a gauge pin of a gauge (13) is pointed to the large flange and the gauge is set to a zero position; the gauge is pulled along the guide rail and change values of gauge reading are observed; if the gauge is still located at the zero position, the large flange is parallel to the guide rail and the included angle between the large flange and the conical outer rolling path is equal to the omega with no machining error; and if the gauge produces changes, the large flange is not parallel to the guide rail and the included angle between the large flange and the conical outer rolling path is not equal to the omega with a machining error. The detection and judgment method for the included angle between the inner ring conical rolling path and the large flange has the advantages of being intuitive and clear and definite in detection and judgment.

Description

technical field [0001] The invention belongs to the technical field of bearing raceway measurement, and in particular relates to a method for detecting and judging the angle between the tapered raceway of the inner ring of a tapered roller bearing and a large rib. Background technique [0002] figure 1 It is a schematic diagram of the cross section of the inner ring of a tapered roller bearing. The inner ring has a conical raceway. A small rib and a large rib are respectively arranged at both ends of the conical raceway. The small rib and the large rib The sides have the same inclination relative to the conical raceway. The end face of the inner ring adjacent to the small rib is called the small end face, and the end face of the inner ring adjacent to the large rib is called the large end face. Side length ≤ the side length of the large rib, and the horizontal width L corresponding to the large rib can be given by actual measurement, L={maximum outer diameter-outside of t...
