Roller generatrix rough profile detection device and method of cylindrical roller bearings

Abstract

The invention discloses a roller generatrix rough profile detection device and method of cylindrical roller bearings. The detection device comprises a surface rough profile measuring instrument and a bearing clamping positioning device; the surface rough profile measuring instrument comprises a base, an upright column, a driving electric box, an electric inductance sensor and a measuring pin; the bearing clamping positioning device includes an X-axis worktable, a Y-axis worktable, a bearing positioning fixture and a bearing baffle, wherein the X-axis worktable is slidingly connected onto the base, the Y-axis worktable is slidingly connected onto the X-axis worktable, an X axis is the axial direction of a measured bearing of which the outer ring has been removed in detection, a Y axis is vertical to the X axis, the Y axis and the X axis are in the same horizontal plane; the bearing positioning clamp is arranged on the Y-axis worktable; the bearing baffle is arranged on the Y-axis worktable; after the outer ring of the measured bearing is removed, the measured bearing is installed in the bearing positioning clamp; one side end surface of the measured bearing of which the outer ring has been removed contacts with the bearing baffle. With the roller generatrix rough profile detection device and method of cylindrical roller bearings of the invention adopted, detection accuracy can be improved.

Description

technical field [0001] The invention relates to a device and method for detecting the roughness profile of a roller busbar, in particular to a device and method for detecting the roughness profile of a roller busbar of a cylindrical roller bearing, belonging to the technical field of bearing detection. Background technique [0002] As one of the key components of the motor, the reliability of the bearing directly affects the safe operation of the motor. Such as figure 1 As shown, the rollers of the used cylindrical roller bearings will have uneven wear on the surface of the rollers due to the intrusion of impurities or abnormal wear. dumbbell-shaped feature. [0003] The existing maintenance technical plan is to conduct a factory test for each motor returned to the factory, and the inspectors decide whether it needs to be replaced according to the vibration and abnormal sound of the motor cylindrical roller bearing. However, this method has extremely high requirements on ...

AI Technical Summary

Problems solved by technology

[0005] (1) The fixed bearing positioning fixture is used. Due to the narrow operating space of the equipment itself, it is very easy to touch precision components such as inductance sensors and probes during bearing clamping and disassembly operations, which affects the detection accuracy, resulting in poor detection accuracy. too reliable;

[0006] (2) The position of the tested bearing after being clamped cannot be adjusted according to the actual situation, which will also affect the detection accuracy

[0007] Therefore, the existing technology has shortcomings such as inconvenient operation and low detection accuracy, which cannot meet the needs of convenient and efficient bearing precision detection
