Abstract
The present application belongs to the technical field of mechanical equipment manufacturing, and particularly relates to a grease stirring resistance and viscous resistance measuring device and method. The stirring resistance and viscous resistance measuring device is designed according to the geometric configuration relationship between the rolling body and the rolling track, and can represent, calculate and evaluate the stirring resistance and viscous resistance of the rolling bearing grease. The gravitational potential energy is converted into kinetic energy and then into internal energy received by the rolling body during operation. The stirring resistance and viscous resistance of the grease under different motion conditions are calculated by using the energy conversion method. The reliability is verified through measurement tests, and the measurement results can be further used as a technical standard for judging the physicochemical properties of the grease, and have good application prospect. The device structure is simple and effective, the measurement means and method are standardized, and can provide a basis for estimating the stirring resistance and viscous resistance of the grease.
