METHOD AND APPARATUS FOR TESTING BEARINGS

摘要

PURPOSE: A method and a device for inspecting a bearing are provided to efficiently and rapidly perform a bearing test and to improve the accuracy of the test. CONSTITUTION: A device for inspecting a bearing comprises an upper jig(20), a lower jig(30), and an inner insulating membrane. The upper jig fixes the upper part of a bearing set(10). The lower jig fixes the lower part of the bearing set. The inner insulating membrane covers the upper jig, the bearing set, and an inner surface of the lower jig. A space where a gas or a fluid for controlling temperature can be injected is formed by the inner surface of the jig and the inner insulating membrane. The bearing set comprises an upper bearing having inner and outer wheels and a lower bearing and an adapter joining the upper bearing and lower bearing. The insulating membrane comprises one or more openings and the gas or the fluid for controlling the temperature is injected to the space through the opening.
