TESTING DEVICE FOR THIN-WALLED LARGE-SIZED BEARING

摘要

A testing device includes: a face board allowing a thin-walled large-sized bearing as a test target to be installed thereon; a face board support mechanism supporting the face board such that the face board can be tilted about a tilting central shaft; an angle change drive device for changing a tilt angle of the face board; a bearing rotation motor for rotating an inner ring of the bearing; and a weight for generating a moment load to the bearing. The face board support mechanism and the angle change drive device are capable of changing the orientation of the face board in a range from a horizontal orientation through a vertical orientation to a tilted orientation. The face board is provided with a dedicated frame to be fitted to an outer circumference of the bearing and attached in a fitted manner to the face board.
