Description

Technical Field

[0001] The present invention relates to the technical field of bearing detection, and particularly relates to a bearing clearance detection device. Background Art

[0002] A bearing is an important component in contemporary mechanical equipment. Its main functions are to support a mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. There are many detection parameters for bearings, such as rotational accuracy, vibration, axial clearance, radial clearance, etc. Among them, the bearing clearance is also called the bearing gap. The so-called bearing clearance refers to the amount of movement when one of the inner or outer rings of the bearing is fixed while the other non-fixed side of the bearing clearance makes a radial or axial movement when the bearing is not installed on the shaft or bearing housing. The radial clearance of the bearing directly affects the operating performance of the bearing, such as noise, vibration, and service life. Therefore, the detection of bearing clearance is particularly important.

This device consists of a dynamometer, a clearance measuring instrument, a loading slide table, an unloading slide table, a bearing fixture, and a frame. The bearing fixture installs the spherical plain bearing between two dynamometers. The dynamometers are installed on the loading / unloading slide tables, and the loading / unloading slide tables are installed on the frame. The clearance measuring instrument is fixed on the frame. The present invention integrates the detection of the axial clearance and radial clearance of the spherical plain bearing into one device, and can measure the axial clearance and radial clearance of the spherical plain bearing by replacing different bearing fixtures.
