Abstract

The invention discloses a flexible bearing noise test platform based on harmonic vibration, which comprises an alarm system, a loading system, a data acquisition system, a sensor and an electrical control platform, and is characterized in that the sensor is connected with the data acquisition system, the data acquisition system alarms for an abnormal signal through the alarm system, and the rotating speed of the test platform is controlled by the electrical control platform. Compared with a common bearing test platform, the flexible bearing noise test platform based on harmonic vibration has the advantages that the loading range is wider, the axial force and the radial force can be adjusted according to requirements, acquired data is more comprehensive and comprises noise, rotating speed and torque, and compared with the bearing test platform controlled by a common motor, a servo motor can steplessly control the rotating speed of the bearing. Generally speaking, the loading convenienceand intuition of the flexible bearing test platform are greatly improved, the data visualization effect is good, and the corresponding relation between the bearing noise and the working condition iscomprehensively and accurately tested.

Description

technical field [0001] The invention belongs to the technical field of bearing multifunctional test platforms, and relates to a bearing noise test platform, in particular to a flexible bearing noise test platform based on harmonic vibration. Background technique [0002] Harmonic flexible bearing is an important part of harmonic drive assembly, which has the characteristics of thin-walled deformation bearing. Under the working conditions of changing bearing radial force, axial force and input speed, the flexible bearing test platform can test the running noise of bearings in different states, and can also be used for more efficient, low-friction, low-noise harmonic reducer flexible bearings. test. At present, the domestic harmonic reducer is still in the stage of high noise. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a flexible bearing noise testing platform based on harmonic vibratio...
