Detection method for included angle deviation of raceway of cylindrical roller bearing inner ring and reference end surface

Abstract

The invention provides a detection method for an included angle deviation of a raceway of a cylindrical roller bearing inner ring and a reference end surface. The bearing inner ring of which the inner diameter is greater than 300mm is self-defined as a large thin-wall sealed intersectional cylindrical roller bearing inner ring and is called as inner ring (5) for short, wherein the raceway of the inner ring is in a V shape; the two raceway edges of the V-shaped raceway are intersected to form an angle of 90DEG and respectively form angles of 45DEG relative to the symmetrical centerline of the V-shaped raceway; and the detected included angle deviation is compared with delta beta' in a graph 3 in a CSBTSTC98-13-1997 standard, so as to be judged whether satisfies the requirement of the standard or not. A dial indicator (1), a magnetic indicator stand (2), a sine gauge (3) and a block gauge (4) are used in the detection method, the difficult problems that the large bearing inner ring is difficult to detect and is detected incorrectly are solved, and angle deviations of raceways of inner rings in the whole batch can be detected repeatedly and rapidly after the sine gauge and the block gauge are well adjusted once, the influence of personal factors is reduced, the detection efficiency is obviously improved and the detection cost is saved.

Description

[0001] Technical field [0002] The present invention is a bearing measurement technology field, which specially involves a detection method for the corpus roller inner ring roller lane and the benchmark end surface angle deviation.The inner ring of the cylindrical roller bearing refers to the large thin -walled sealing cross -cylindrical roller bearing inner ring. [0003] Background technique [0004] Combine figure 1 , Customized the inner ring with the inner ring with a diameter of more than 300mm as a large cross -cylindrical roller bearing inner ring.At 90 °, the V -shaped road in the inner ring of the bearing is equipped with a circle of cross -cylindrical roller.Because the angle deviation of β = 90 ° is high, it directly affects the manufacturing accuracy and service life of the cross -cylindrical roller bearings. [0005] According to the standard CSBTS TC98-13-1997, large thin-walled sealing cross-cylindrical rolling inner ring needs to detect the deviation of the bear...
