Problems solved by technology

Since the accelerometer needs to be connected to the circuit board and the data cable, simply fixing the accelerometer to the detection part with fasteners such as screws will obviously lead to loosening of the fixed position, and the detection data of the accelerometer will also deviate

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as Figure 6-7 As shown in Fig. 1, a method for detecting three-axis vibration of a spindle bearing with a high-frequency uniaxial accelerometer, the spindle connector 1 is set on the spindle to be tested, and three high-frequency uniaxial accelerometer components are arranged on the spindle connector 1 2. The detection surfaces of the three high-frequency uniaxial accelerometer assemblies 2 correspond to the X, Y, and Z-axis directions of the main shaft respectively, and the frequency detection limit of the high-frequency uniaxial accelerometer assembly 2 is at least 10,000 Hz.

[0035] The main shaft connector 1 here may be a front end cover, a rear end cover or a shaft sleeve, etc., which is not limited here. The high-frequency uniaxial accelerometer assembly 2 is connected with a data line for conducting vibration detection data.

[0036] The X, Y and...

Abstract

The invention provides a method for detecting triaxial vibration of a spindle bearing through high-frequency uniaxial accelerometers, and belongs to the technical field of bearing spindle working condition detection. According to the method, a spindle connecting piece is arranged on a to-be-detected spindle in a sleeving mode, three high-frequency uniaxial accelerometer assemblies are arranged onthe spindle connecting piece, and the detection faces of the three high-frequency uniaxial accelerometer assemblies correspond to the X-axis direction, the Y-axis direction and the Z-axis direction correspondingly. Triaxial high-frequency detection can be achieved.

Description

technical field [0001] The invention belongs to the technical field of working condition detection of a bearing main shaft, and relates to a method for detecting three-axis vibration of a main shaft bearing by using a high-frequency single-axis accelerometer. Background technique [0002] Conventional accelerometers are electronic components used to measure vibration frequency. Accelerometers are divided into single-axis, double-axis and three-axis accelerometers. In the test of the working condition of the bearing spindle, it is usually necessary to detect the X, Y and Z coordinates. Vibration, so the choice of three-axis accelerometer is the first choice. [0003] The detection frequency of the commercially available three-axis accelerometer is usually between 500-1600Hz, and the price is about NT$70. During the working process of the spindle and the bearing, when the linear speed of the bearing meets the critical point, there will be an instantaneous high speed. Frequenc...
