Research on Durability Test Method for Wheel Bearings

摘要

The paper discusses durability test methods for wheel bearings. Through studying on the offset between the center line of a wheel and the center line on which the tire is forced, we get the determination method for the simulating load position on the wheel bearing. Depending on the influence study of inner circle or outer circle rotating method to the life performance of the wheel bearings, we give the test method on the bench. Based on the discussing of the bench monitoring method of wheel bearings, we give the effective and simple method to determine the failure of wheel bearings with Kur tosis.
