Abstract

The invention discloses self supporting type bearing vibration measurement device. It includes frame, platform, electric machine driving mechanism, baiting machine, transducer, and electric probe device. Its features are as follow: it includes lower bearing, coupling, flywheel, satellite, supporting machine, fast changing type core axle, and pendulous axis; the coupling is movable elastic coupling includes upper and lower two half couplings; the upper half coupling is fly wheel rigid coupling with the lower end of the pendulous axis of which upper end is muff coupling with the fast changing type core axle; the core axle is supported the tested bearing set on the supporting machine set the platform; the lower half coupling is connected with the electric machine driving mechanism. The invention adopts pendulous axis and tested bearing self supporting structure to make the bearing vibration measurement avoid the accurate spindle constraint, relies on bearing self parameter rotating to remove principal axis axiality and its vibration interference to further increase measuring accuracy.

Description

technical field [0001] The invention relates to a device for measuring mechanical vibration by detecting changes in electrical characteristics. It is a bearing vibration measuring instrument that uses the bearing itself to support the drive shaft to rotate, thereby reducing the measurement error caused by the coaxiality and vibration of the main shaft. Background technique [0002] In the prior art, the measurement of bearing vibration all adopts low-vibration precision spindle as the supporting shaft of the bearing under test. The measurement error caused by the coaxiality of the spindle and vibration is difficult to eliminate, thus limiting the accuracy of bearing vibration measurement. improve. In order to overcome the error caused by the spindle to the measurement, the most reliable way is to cancel the spindle seat, directly support the support shaft in the bearing under test, and make the bearing under test rotate with its own performance parameters.
