A vibration velocity testing device for bearings

Abstract

The invention provides a vibration velocity testing device for bearings, which relates to the technical field of bearing testing, and includes a supporting device: a linkage propulsion part is installed on the support device; a mounting part is rotatably connected to the linkage propulsion part; A displacement expansion part is connected; the bottom of the linkage propulsion part is connected with a docking drive part; the support device is fixedly connected with a reverse acceleration device; the support device is fixedly connected with a main shaft drive part; the reverse acceleration device is slidably connected with a floating detection part; The structure is simple and efficient, the data is accurate, and the bearing coaxiality is high; the present invention solves the problem of low test efficiency of the current bearing vibration speed test device, which affects the accuracy of the test data, cannot realize the reverse acceleration test of the docking, cannot realize the floating detection, and has poor adhesion question.

Description

technical field [0001] The invention relates to the technical field of bearing testing, in particular to a vibration velocity testing device for bearings. Background technique [0002] Bearings are widely used and play an important role in the mechanical structure. It is an important basic component of various mechanical equipment. Its accuracy, performance, life and reliability play an important role in the accuracy, performance, life and reliability of the host It plays a decisive role, so the performance of the bearing needs to be tested before it is put into production. At this time, a good bearing vibration speed test device is particularly important in the bearing production process. [0003] However, as far as the current vibration velocity test device for traditional bearings is concerned, the test efficiency is low, and at the same time, the automatic expansion of the fixed bearing cannot be realized, and the coaxiality is poor, which affects the accuracy of the tes...

Problems solved by technology

[0003] However, as far as the current vibration velocity test device for traditional bearings is concerned, the test efficiency is low, and at the same time, the automatic expansion of the fixed bearing cannot be realized, and the coaxiality is poor, which affects the accuracy of the test data. The limit data is not complete, the safety is poor, and it cannot assist in the realization of floating detection. The test range of the bearing is small, it is not convenient to install the bearing, and the adhesion is poor during the vibration of the bearing.
