Vibration speed testing device for bearing

Abstract

The invention provides a vibration speed testing device for a bearing, and relates to the technical field of bearing testing, and the vibration speed testing device comprises a supporting device which is provided with a linkage propelling part; the linkage propelling part is rotationally connected with a mounting part; a displacement expansion part is fixedly connected to the supporting device; the bottom of the linkage propelling part is rotationally connected with a butt joint driving part; a reverse acceleration device is fixedly connected to the supporting device; the supporting device is fixedly connected with a main shaft driving part; and the reverse acceleration device is connected with a floating detection part in a sliding manner. The vibration speed testing device is simple and efficient in structure, accurate in data and high in bearing coaxiality. The bearing vibration speed testing device solves the problems that an existing bearing vibration speed testing device is low in testing efficiency, influences detection data accuracy, cannot achieve butt joint reverse acceleration testing, cannot achieve floating detection and is poor in attaching performance.

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.
