Embodiment Construction
[0054]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0055] As mentioned above in the background art, the damping performance of the damping grease is mostly measured by testing the performance of the material itself. However, in actual use, the performance of the damping grease is greatly affected by the use environment. For example, if the temperature of the environment is too high or too low,...

The invention provides a grease damping testing device and method. The damping testing device comprises a base, a driving part and a rotating part, wherein the driving part is connected with the base, the rotating part is located between the driving part and the base, the first end of the rotating part abuts against the base, the second end of the rotating part is connected with the driving part, and the driving part can drive the rotating part to rotate relative to the base. The driving part is further used for being connected with a torsion testing piece, a grease storage area is formed between the first end and the base, and the grease storage area is used for containing grease. Through the damping testing device, the application environment of damping grease can be simulated, for example, the damping test device can be placed in different temperature environments, torsion data of a rotating part in different temperature environments can be obtained, namely the damping performance of the grease at different temperatures can be obtained, and then the influence of the temperature on the damping performance of the grease can be known, so that the judgment of the grease damping life is realized, and the accuracy and reliability of the judgment of the grease damping performance are effectively improved.
Description
technical field [0001] The invention relates to the technical field of grease damping performance testing, in particular to a grease damping testing device and testing method. Background technique [0002] Damping grease is a kind of lubricating grease with special purpose. It is applied between two friction surfaces for damping, lubrication, vibration reduction and sealing. It is widely used in electronic devices. For example, it is often used in devices such as mobile phones, telescopes, microscopes, cameras, and measuring instruments. [0003] Usually, the damping performance of damping grease is mostly measured by the properties of the grease material itself, such as the viscosity, consistency, dropping point or cone penetration of the grease. However, the damping performance of damping grease is different in different use environments, such as different temperature conditions. Therefore, the service life of damping grease is greatly affected by temperature, and the dam...
