Abstract

The invention relates to a rolling bearing vibration detection device. The rolling bearing vibration detection device comprises a bearing vibration measuring unit, a spindle rotation error measuring unit and a base, wherein the bearing vibration measuring unit and the spindle rotation error measuring unit are respectively and fixedly installed on the base and are located on the two sides of a spindle of a rolling bearing to be measured; the bearing vibration measuring unit comprises a contact-type vibration sensor and a three-dimensional micro-displacement platform, the contact-type vibration sensor is fixedly arranged on the three-dimensional micro-displacement platform, the three-dimensional micro-displacement platform is fixedly arranged on the base; and the contact-type vibration sensor can translate along the radial, axial and vertical direction of the rolling bearing to be measured; the spindle rotation error measuring unit comprises a displacement sensor and a two-dimensional micro-displacement platform, the displacement sensor is fixedly arranged on the two-dimensional micro-displacement platform, the two-dimensional micro-displacement platform is fixedly arranged on the base and the displacement sensor can translate along the radial and vertical direction of the rolling bearing to be measured. The invention further relates to a rolling bearing vibration analysis method.

Description

technical field [0001] The invention relates to a rolling bearing vibration detection device and analysis method, in particular to a rolling bearing vibration detection device and analysis method capable of eliminating the influence of the spindle rotation error. Background technique [0002] As the slewing support part of the spindle of high-speed precision CNC machine tool, the rolling bearing's own motion stability directly affects the machining accuracy of the machine tool. With the continuous improvement of the machining accuracy of modern CNC machine tools, the requirements for the dynamic performance of rolling bearings are getting higher and higher, and bearing vibration has become one of the items that must be assessed. Bearing vibration refers to the movement of the internal parts of the bearing that deviates from the ideal position in addition to the movement necessary for the function during the operation of the bearing. In practical application, when the bearin...
